• What Was Life Like Before Air Conditioning Systems?

    It can be hard to imagine a hot Florida summer day without the cooling effects of air conditioning in our vehicles, homes, and work. Yet, for practical purposes, air conditioning systems as we know them today have not really been standard comfort for that long.

    What was life like for people who lived in Florida before homes had air conditioning? Let’s take a look back to see what events helped pave the way for modern air conditioner systems. Then we will look at what methods they used to stay cool and survive the heat.

    Guy Sweating

    The Mid to Late 1800s

    A lot was going on in the mid-1800s. To begin with, Florida went from being a territory of the United States to becoming an actual state on March 3, 1845. Florida was the 27 th state to become part of the growing and expanding U.S.

    In 1851, Floridian Dr. John Gorrie was granted a patent for the first-ever ice-making machine. The machine would start to produce ice commercially in just a few short years. His invention would also result in a new appliance for the home: the icebox.

    Another new invention that came about in 1882 was the invention of the electric fan. While fans had been around for quite some time, they had to be operated either manually, using steam power, or by burning oil or kerosene.

    Old Fans

    The Early to Mid-1900s

    The first air conditioner was invented in 1902 in New York by engineer Willis Carrier. Mr. Carrier was looking for an effective way to remove humidity from a building used to for publishing. Inadvertently, his invention not only solved that problem but also created artificially cooled air to help keep workers cool, too.

    In 1904, those attending the World’s Fair in St. Louis were in for a new treat: the concept of indoor cooling. The Missouri State Building was cooled using Mr. Carrier’s invention.

    Mr. Carrier redefined his invention in 1922 when he developed and created new centrifugal chillers. These new chillers improved the efficiency of the air conditioner, while at the same time reduced the costs to build cooling systems.

    In 1928, chlorofluorocarbon (CFC) refrigerants are synthesized at General Motors by Robert McNary, Thomas Midgley, and Albert Henne during a project for Frigidaire. The result of their efforts was the creation of the first non-flammable refrigerant chemicals that could be used in refrigerators and in air conditioners.

    Old Air Conditioning

    Frigidaire released the first cooling units for rooms in 1929, largely thanks to the creation of CFCs. General Electric also designed their own cooling units and built 32 of them between 1930 and 1931.

    In 1931, Frigidaire expanded upon its AC production and developed the first-ever central cooling systems for homes. In the same year, two inventors, J.Q. Sherman and H.H. Schultz, filed for a patent for window air conditioning units, which were released in 1932.

    The creation of a low-cost window air conditioner unit occurred in 1947, thanks to engineer Henry Galson. That same year, 43,000 of these new units were sold to homeowners.

    The Mid to Late 1900s

    Advances in air conditioning designs continued to improve in the mid-1900s. New homes were being built with central air conditioning systems . The prices on window units continued to drop, allowing people with older homes but no ductwork to also cool their homes.

    In the 1960s, most homes had either central air conditioning or window units to help stay cool year round. By the end of the 1960s, people were starting to migrate to new areas of the country. Two of the states that saw the most population growth during this time were Florida and Arizona.

    Then the energy crisis of the 1970s hit. The U.S. Department of Energy developed different programs that required energy improvements be made in appliances, including air conditioners. Since that time, improvements have gradually been made to make air conditioning more energy efficient.

    New Air Conditioning

    In the 1990s, concerns over greenhouse gases like CFC began to become more mainstream. Fortunately, other synthetic coolants were able to be invented that are eco-friendly and still help keep people’s homes cool.

    By 2000, air conditioning units being built were more energy-efficient and eco-friendly compared to units built in 1990. On average, the units built in 2000 were as much as 50% more energy efficient. These improvements have continued through today, with 2018 units being more energy efficient compared to models built in 2008.

    How People Stayed Cool Without Air Conditioning

    As we saw, the widespread of use of air conditioning by homeowners did not really start to happen until the 1960s. Even though air conditioning was essentially available since 1930 for homeowners, it was still an expensive luxury most people could not afford. Instead, they turned to other ways to stay cool.

    Homes built during the mid-1800s to mid-1900s were designed differently. One key feature was the use of high vaulted ceilings. On hotter days, the warmer air would rise and collect at the ceiling level and go out vents or windows. By having higher ceilings, the air below would be cooler.

    Another feature found in homes during this time were windows on opposite sides from each other. By opening windows on opposite sides of the home, it created a natural breeze and air flow. In two-story homes, people would open all of the upstairs windows to create air flow and allow the heat from the lower floor to escape.

    Patio with Table and Chairs

    One key feature found in homes from this period were wide, long, and covered front and back porches on the north and south sides of the homes. The porches provided sufficient shade from the sun and were much cooler than staying indoors on hot summer days.

    Homeowners also planted trees on the east and west sides of the home to provide shade. Mature trees would help stop direct sunlight from shining into the home and help keep it somewhat cooler inside.

    In the evenings, it was common for people to sleep downstairs, if they had a two-story home, because the upstairs bedrooms were too warm. In homes with basements, these were used more frequently in the summer months since they were naturally cooler.

    Aside from how homes were built, people became resourceful to escape the heat. People would go to the movies more often in the summer as most theaters in the 1920s and onward had central air conditioning. They could enjoy watching the latest Hollywood films in the cool indoor air and get a brief reprieve from hot summer days and nights.

    In the 1920s, the prices of electric fans dropped and were much more affordable. Many homes started using window box fans and ceiling fans to help create air flows to cool the indoor air.

    Another effective cooling method was to make a swamp cooler using the scientific principle of evaporative cooling. People would hang up wet sheets and clothing inside the home. As air blew on it, either naturally from a cross breeze in the home or from fans, it would cause the water to evaporate into the air and lower the surrounding air temperature.

    People also would order extra ice for their icebox and place one block into a steel tub. They would set up a fan next to the tub and turn it on. As the ice melted, it released cold air. By using the fan to circulate this air in the room, it essentially became an air conditioner thanks to evaporative cooling.

    In addition to these methods, people would take sheets and clothing and place them in the freezer to cool them down before using them. Some people would even freeze wet sheets before hanging them up as part of their indoor swamp cooler to make the cooling effects last longer.

    In the 1950s and the 1960s, attic fans were very popular. These types of fans were also referred to as whole house fans because they were installed in the attic. They would suck up the hot air out of the home and vent it outdoors through the attic. Even after central and window air conditioning became more standard, attic fans were still used to help remove hot air from homes.

    Eventually, as air conditioning systems became more affordable, people did not have to worry about coming up with creative ways to remain cool on hot summer days. The only time they would have to worry is when their air conditioner stopped working.

    How to Stay Cool Year Round Today

    Homeowners today rely on their air conditioning systems to stay cool year round. Even in the middle of winter in Central Florida, we can have periods of heat with temperatures in the upper 80s and low 90s. One mistake homeowners make is not performing semi-annual maintenance on their home’s heating and cooling system.

    Skipping maintenance is not good because it can lead to unexpected breakdowns and emergency service calls. In addition, systems that are not well-maintained have a much shorter lifespan and have to be replaced more often.

    To ensure your home remains cool and you do not have any surprise problems with your home’s air conditioning, please feel free to call Air Rescue at (813) 612-5600 to schedule preventative maintenance today!

  • The Benefits of Humidifiers and Dehumidifiers

    Aside from your home’s heating and air conditioning (AC) system, two “accessories” some homeowners use are humidifiers and dehumidifiers. These optional components provide different benefits to ensure indoor air quality is maintained year round. They help enhance the efficiency of your home heating and cooling system, as well as help keep ducts cleaner so you need less frequent air duct cleaning .

    The objective of both humidifiers and dehumidifiers is to regulate and control the amount of relative humidity in the air inside the home. Ideally, you want to have indoor air humidity levels between 35% and 50% relative humidity. In the wintertime, you will want the humidity levels to be closer to 50%, while in the warmer months you want to keep the percentage of humidity in the high 30s to low 40s.

    Let’s take a look at what humidifiers and dehumidifiers are, the benefits they provide, and why you need one for your Tampa Bay Area home.

    Air Conditioning Thermometer

    What Is a Humidifier?

    A humidifier helps add humidity to indoor air. It is perfect for dry air conditions that can cause humidity levels to drop below 35% relative humidity. There are small units that work well in small, individual rooms. You will also find larger units that help humidify multiple rooms or bigger areas in open floor plans. In addition, there are humidifiers that can be connected directly to your home’s central heating system to humidify the entire home.

    What Are the Benefits of a Humidifier?

    During the colder winter months, the relative humidity in outdoor air drops significantly. This drop also occurs inside your home. As the humidity levels drop, it can cause a variety of problems, from dry skin to colds and flu. Using a humidifier offers these benefits:

    • Helps keep skin soft and moist. If you notice your skin cracking, peeling, or feeling itchy in the winter, you most likely have low humidity levels.
    • Helps keep indoor plants healthy. Even your houseplants can suffer from reduced humidity levels in the winter. While they do get some moisture when you water them, they also draw in water from the surrounding air. If you notice your plants do not seem happy in the wintertime, it could be caused by insufficient humidity in the air.
    • Helps reduce the spread of illnesses. Bacteria and viruses are unable to spread as easily in humid air. This is why people rarely get a cold or flu in the summer.
    • Helps prevent sinus infections/problems. If you have sinus problems or get regular sinus infections in the winter, increasing the amount of humidity in the air can help. As you breathe in the humidified air, it restores moisture to the nasal and sinus passages.
    • Increases recovery time should you get sick. In the event you do get a cold, flu, or sinus infection, using a humidifier can help shorten the time you are sick. Symptoms like sore throat, running nose, coughing, and sneezing are also reduced with higher humidity levels.
    • Makes it feel warmer inside on those cold and brisk days. Dry air will feel colder than it really is because of the lack of humidity. Humidifying the air helps add moisture and this also helps make you feel more comfortable. As such, you may not need to keep the thermostat set as high and could reduce your heating bills.
    • Eliminates static electricity from the air. If you have problems with static electricity in the wintertime, this is because there is not enough humidity in the air. Using a humidifier will get rid of static electricity and those surprise shocks!

    Why Do I Need a Humidifier in Tampa?

    Tampa and the Tampa Bay Area tend to be warm with humid air conditions most of the year, although, from November through mid-to-late February, temperatures can become unseasonably cold without any warning.

    Whenever the jet stream drops and pulls the cold northern air down from Canada, it can reach all the way to the Tampa Bay Area. If it remains around for several days, the humidity levels quickly drop.

    In addition, with cooler winter temperatures and shorter days, the humidity levels will also drop on their own. This is why an 80-degree day in January feels much more comfortable than an 80-degree day in April.

    This past winter, temperatures were much colder than they have been in quite some time. If you experienced a shock when you opened your January heating bill, you definitely should consider getting a humidifier before next winter—not to mention all the other benefits it can provide to improving the indoor air quality during the wintertime in your home.

    Man Pointing at Humidifier

    What Is a Dehumidifier?

    A dehumidifier helps remove humidity from indoor air. It is well-suited for humid conditions where indoor humidity levels are higher than 50% relative humidity. There are small dehumidifiers that can be used in a single room and are perfect for small rooms in the home. There are also larger capacity dehumidifiers that work well in open floor plans and larger rooms. You will even find whole-home dehumidifiers that can be connected to or built-in as part of your home’s AC system.

    Air Humidifier

    What Are the Benefits of a Dehumidifier?

    Dehumidifiers remove moisture from the air which provides many benefits for homeowners. Most modern portable units are quieter than previous generations. While some of these units do require you to empty the water pan when it is full, others can be connected directly to a discharge drain. You also do not have to worry about emptying the water pan on whole-home systems.

    Some of the more common benefits gained include:

    • Better indoor air quality. It is important to maintain the right humidity levels in the home year-round. During the warmer spring, summer, and fall months, humidity levels are much higher, so the air inside can also be more humid.
    • Reduces and eliminates musty odors from the home. If your home smells musty, this is a sign you have high humidity indoors. Regularly using a dehumidifier can help get rid of this odor and make your home smell better.
    • Helps alleviate allergies. If you suffer from allergies, higher humidity levels can sometimes trigger reactions. Lowering the amount of humidity will help those with allergies to dust, pet dander, pollen, dust mites, mold, and mildew.
    • Helps reduce asthmatic symptoms in people with asthma, as well as other respiratory conditions. Increased humidity levels can irritate respiratory conditions, including asthma. Reducing humidity levels makes it easier to breathe and avoid having an attack.
    • Reduces the likelihood of mold and mildew in the home. Mold and mildew thrive in moist, damp, and humid environments. This is why both are typically found primarily in bathrooms. Yet, if you have problems with mold and mildew in other rooms of the home, you will want to reduce humidity levels to resolve this issue.
    • Slows the growth and spread of dust mites. Dust mites are small microscopic creatures that feed on pet dander and dead skin cells. They thrive and increase in numbers when there are higher humidity levels inside the home. Reducing the amount of humidity in the air helps reduce their numbers.
    • Helps reduce condensation problems within the home. If you notice condensation on your walls, windows, or other areas inside the home, this is often caused by the cooled indoor air reacting with the humidity in the air. As it cools, it turns from a water vapor into a water.
    • Makes you feel cooler when indoors. Removing excess humidity will make the indoor air feel cooler naturally since a dehumidifier does help cool a room . When you feel cooler, you may not need to turn down the thermostat as much and could save on your cooling costs.

    Why Do I Need a Dehumidifier in Tampa?

    Tampa and the entire Tampa Bay Area are next to the Gulf with numerous inlets and other freshwater rivers, marshes, and streams nearby. Being near a constant source of water typically results in higher humidity levels from the early spring through the late fall.

    Not only is the outdoor air more humid, but also the air inside your home. A good sign humidity levels have risen indoors is if the air feels “stuffy” even while the air conditioner is cooling the home. If you want to come home to better quality air that is not “stuffy” after a long day at work, then you will want to get a dehumidifier for your home.

    Air Rescue recommends a whole-home dehumidifier solution for homes in the Tampa Bay Area. A whole-house solution makes it easy to remove humidity from multiple rooms more efficiently compared to portable units.

  • Boost the Efficiency of Your Air Conditioner with Decorative Window Treatments

    engergy efficient sunshades for your home

    There are cost-effective ways you can boost the efficiency of your home’s air conditioning using decorative window treatments. These can help stop the transfer of heat into your Tampa Bay Area home and keep it cooler. The overall effectiveness of window treatments depends upon the type used and other factors, which we will review in greater detail below.

    It is worth noting, if you have air leaks around your windows, window treatments cannot stop or prevent this type of problem. Instead, you will need to have your windows resealed using caulking or weather-stripping to stop and prevent any noticeable air leaks. Even here in Florida, it is a good idea to reseal your windows annually as the hot sun can cause caulk and weather-stripping to crack and peel.

    Exterior Windows Treatments

    There are a few different types of exterior window treatments you can add to your home to improve the efficiency of your air conditioning. Some of these can also improve the exterior appearance of your home—so you get a two-for-one bonus with these!

    • Closeable Shutters: Window shutters on the exterior of the home highlight the window and are a great accessory to give your home more charm. Closeable shutters allow you to pull them shut on windows that get direct sunlight and stop the UV rays and solar heat from transferring through the glass window panes and into the home.
    • Windows Screens: Window screens can help diffuse solar heat and UV rays. The mesh of the screen should be made from a high-quality material. To gain this benefit for the full window, select screens that cover the entire window.
    • Awnings: Awnings can be added above windows to block out sunlight and serve as a shade. Awnings come in different materials, from canvas and metals to synthetics. There are even awnings that use solar panels for the shade. Not only are you reducing solar heat gain into the home, but you are also generating electricity for your home at the same time!

    More traditional awnings can be installed with adjustable arms. These allow you to adjust the angle of the awning, as well as retract the awnings when you don’t want to shade the windows.

    • Roof/Window Overhangs: If you are building a new home, consider adding overhangs over windows that will get direct sunlight. Overhangs are easiest and less expensive to add during new home construction. For existing homes, making this type of renovation can be rather costly, so awnings are often a more cost-effective way to add overhangs.
    • Storm Panels: This option allows you to stop heat gain by essentially blocking out the light from coming into the home. Storm panels aren’t as attractive as closeable shutters. However, most people already have these for their homes in case of a bad tropical storm or hurricane.

    Interior Window Treatments

    Inside your home, there are just as many different options from which to choose to help block out the bright sunlight and maintain cooler indoor temperatures. Best of all, you can use more than one of these on your windows to increase the benefits and efficiency of your air conditioning!

      Enegy Saving - Curtains and drapes

    • Insulated Cellular Shades : This type of window treatment is normally white on the outward facing side and can be any color you want on the interior side. The white reflects back the bright sunlight and reduces heat gain inside the home. However, the shades must be partially or fully closed so the amount of natural light coming into the room is diminished.
    • Curtains and Drapes : If you have curtains or drapes you can fully close and open, these can help keep your home cooler. The amount of benefit they provide largely depends on the type of materials they are made from, along with their color. For instance, for maximum benefit, the backside of drapes and curtains should be white.
    • Thermal Window Shades: These are similar to conventional window shades, except they are specifically designed to control the amount of heat transfer into the home. You can find reversible styles that are white on one side and a dark color on the other side.

    White should face outward when you want to reduce heat transfer into the home. The dark side is used when you want to increase heat transfer into the home during those brief cold snaps we experience.

    Beautiful Energy saving Blinds

    • Windows Blinds: The quality of the blinds will determine how effective they are at blocking out heat. Thin, plastic blinds are not as effective as thicker wooden styles. Aside from helping keep out unwanted heat, blinds do allow you to control the amount of sunlight coming into the room.
    • Window Films: You can add different types of reflective window films to transform your windows into heat blocking windows. They are ideal for Florida homes since we tend to use our air conditioners almost year round. The thing to remember with films is they will also block out any heat gain during the few, short cooler periods we experience in the Bay Area.
    • Insulated Window Panels: These panels clip or snap into the frame of the window. They can be full sized and cover the entire window or half sized and only cover the upper or lower section. They typically consist of a foam core that is covered in some sort of material to make them more attractive.

    Just like insulated cellular shades, they will block out all sunlight entering the home. However, they are inexpensive whether you purchase a kit, make your own, or custom order them for each window in your home. The only drawback is you will need somewhere to store the panels when you are not using them.

    • Decorative Interior Shutters: You can have decorative, closeable shutters installed inside your home on your windows. This style of shutters can be opened so you have access to the window or be partially or fully closed. Many styles have adjustable louvers you can move to control the amount of light coming into the room while they are closed.
      Decorative interior shutters

    • Quilted Roller Shades: This style of shade has a soft cloth or another type of material on its exterior. There can also be several layers of some form of batting used in its design. The exterior facing side should be white or a light color to reflect sunlight back and help control heat gain into the room. The interior side can be any color you desire to fit with the décor and color scheme in the room.

    By lowering the amount of heat transferred into the home, your air conditioning will have to run less often to maintain your desired indoor temperature. Not only will your home be easier to keep cool, but you could also notice a reduction of your electric bills.

    Will Window Treatments Block Out the Cold, Too?

    Stopping cold air from getting into your Tampa Bay Area home when we have a cold snap is also possible with certain styles of window treatments. Curtains, drapes, shades, insulated panels, and storm panels can all help. However, as mentioned previously, if you have air leaks and your windows need sealing, then these treatments will not be as effective.

    Other Ways to Boost the Efficiency of Your Air Conditioning

    Choosing the right window treatments is just one cost-efficient method for increasing the efficiency of cooling your home. When it comes to your home cooling system, there are several things you should do to further increase its efficiency, as follows:

    • Check your air filter monthly and change it when it is dirty.
    • Have your ducts sealed to stop air leaks.
    • Schedule annual AC maintenance and tune-ups .
    • Have a modern, digital programmable thermostat installed.
    • Have a new air conditioner installed in your unit is more than 15 years old.

    To have any of the above services performed, or if you have questions about AC maintenance and what services your air conditioner needs, please feel free to contact Air Rescue at (813) 612-5600 today!

  • How Do Pets Contribute to Indoor Air Pollution?

    From children of all ages to adults and seniors, pets play an important role in the family dynamic. There are benefits to being a pet owner, such as having a companion if you are single, or helping to lower stress and blood pressure. In seniors, the role of pets helps prevent depression and can help avoid the frustrations of aging since there is a furry friend that requires their attention.

    cat and dog sleeping together

    However, what many people may not realize is that pets and indoor air quality go hand-in-hand . Pets shed hair and skin cells (dander), just like humans do. Excess pet dander and hair in the home lowers the overall air quality. If you or someone in the home suffers from allergies, you may notice you are sneezing more often, experiencing itchy or running eyes more frequently, or having problems breathing.

    Unlike humans, pets tend to shed much more. Pet hair and dander can get into all sorts of places too, such as:

    • On Furniture
    • Under Sofa and Chair Cushions
    • In Bedding
    • Under Beds
    • In Closets
    • In Cracks and Crevices
    • Along Baseboards
    • In Air Ducts

    Keeping pet hair and dander to a minimum requires pet parents to perform some added housekeeping chores more often. Ideally, pet owners should sweep, dust, and vacuum at least weekly. All bedding should also be laundered on a weekly basis.

    In addition, your home’s air conditioning and heating filters need to be replaced more often. Pet hair and dander are easily blown around the home and sucked into the return air vent. The filter blocks most of this but does become dirtier faster.

    dirty air filter

    As a result, we highly recommend checking your AC filter once a month and replacing it when needed. Even if you have a “pet” air filter installed that says it only needs to be replaced every three months, it does not mean it cannot quickly get clogged with pet hair and dander.

    Clogged Air Filters Increase AC Repair Services

    Dirty and clogged air filters cause your air conditioning to work harder. You may notice a spike in your utility bill because the AC has to run longer to achieve the same cooling effects. Additionally, since the AC is running longer, it places more strain on the unit that can lead to overheating, frozen cooling coils, and a host of other problems.

    Furthermore, this added wear and tear on the system shortens the expected lifespan of the entire system. The same is true during the winter months, here in Tampa, when you might need to turn on the heat to warm up your home. Whether you have a “combo” unit or separate furnace and air conditioning system, clogged air filters damage your home’s HVAC system.

    Clogged Air Filters and AC Ducts

    Pets and air quality issues extend into the ducts running throughout your home. Depending on the age of your home, you may have floor ducts, where the ductwork is under the subflooring or ceiling ducts. With floor ducts, you have other things to worry about with pet ownership aside from pet dander and hair.

    • Toys – Your cat or dog could accidentally drop a toy down through the openings in floor ducts. The toys have your pet’s saliva on them and could even contain food particles, pet dander, pet hair, and bacteria.
    • Pet Food – If pet food falls down into the ductwork, not only does it have bacteria and pet saliva on it, but it can also attract unwanted pests like mice and roaches.
    • Kitty Litter – If your cat likes to bat kitty litter around when using the litter box, and it gets down into your ducts, it could have urine and feces on it. Over time, this can make your house smell like one giant litter box!
    • Dirt – Dogs go in and out of the home and can track dirt, mud, feces, and other such materials into the home on their fur and paws. If they walk over open floor ducts, these things can fall into the ducts. The same is true if you let your cat outside from time to time.

    If your home has floor air ducts, we highly recommend to include an inspection of your ductwork during your annual or bi-annual AC maintenance and tune-up visits. This way, if foreign objects, pet hair, and dander are an issue, you can have them cleaned to help maintain better indoor air quality in your home.

    For ceiling ducts, pet hair and dander can still be a problem. It does not hurt to get annual inspections. During inspections, your AC repair technician will look for gaps, openings, and other areas where the ducts are not properly sealed.

    Improperly sealed ductwork can also contribute to increased air pollution in the home, as well as increase your heating and cooling costs. For instance, if there is a large enough gap in between two duct sections, cooled or heated air is escaping.

    As this air is blown out, it can create a suction force that draws in outdoor air or interior wall air, which can also contain dirt and dust. In homes with pets, pet hair and dander can be blown out of the openings as well as drawn back in, which further reduces indoor air quality.

    In addition, in newer homes, rather than traditional metal ductwork, some builders are opting to use heavy plastic ducts instead. While these certainly cost less, they can easily get punctured, torn, and ripped. This can introduce even more contaminants into the home, including animal dander and hair from outdoor animals that might gain entry through the crawl space under your home!

    How Duct Sealing Helps Improve Indoor Air Quality

    When your ductwork has been properly sealed by your air duct repair technician, including around the air vents that are in the rooms in your home, there are fewer potential entry points into the home’s cooling and heating system for pet dander, pet hair, and other contaminants.

    With floor ducts, it is highly recommended to have fine mesh screens installed as part of the sealing process. This way, the screens catch pet dander, hair, food, toys, and kitty litter and keep them out of the ducts.

    Other Air Quality Tips for Pet Owners

    Aside from your regular housekeeping chores, there are other things pet owners can do to help reduce the amount of pet hair and dander that gets distributed around the home, into return air vent filters, and ducts.

    • Brush your pets every few days. Pets shed a lot! You would be surprised by how fast a pet brush or comb gets filled with their pet hair. If you get into the habit of brushing your cats or dogs more often, they will have less hair to shed. Plus, your cats or dogs will appreciate the attention they are getting and will start to look forward to “brush-time.”
    • Move pet items away from floor ducts and the return air vent. Keep pet food, water, bedding, litter boxes and other such items away from floor air ducts, as well as the return air vent. Moving these items away will reduce the number of items that get into ducts, as well as sucked into the air filter.
    • Give your dog a bath regularly. Since dogs spend time indoors and outdoors, they can start to smell really bad. Weekly baths not only help keep your dog from stinking but also wash out pet dander and any pet hair you missed during brushings.

    A word about baths and cats: We wouldn’t recommend giving cats a bath—not unless they like playing in the water and are accustomed to it. You can talk to your vet about a waterless shampoo for your cats to help keep them smelling great if they spend any time outdoors.

  • Proper HVAC Installation Matters

    A new HVAC system represents a big investment, and it’s understandable that some home or business owners will want to cut costs on installation. This can be a grave error if they pick an unqualified contractor to install air conditioning units, as a shoddy installation job can result in long-term problems and expenses.

    hvac technician with safety helmet

    Heating and air conditioning units and their associated ductwork and infrastructure are complex systems that require precise installation. If the job’s not done right, the system won’t perform efficiently and may be more prone to breakage and have a shorter life. Energy Star, a federal program that evaluates appliances for efficiency and environmental impact, estimates that about half of all heating and cooling systems don’t perform as they should because they were improperly installed.

    An HVAC system that’s not providing optimum performance can be costly for home and business owners. HVAC systems account for about 40 percent or more of our energy consumption. Energy Star estimates that improper installation can reduce system efficiency by up to 30 percent .

    monitoring hvac unit

    Qualified air conditioning and heating contractors ensure your system performs at its best by selecting a proper unit and ensuring that the system’s components and infrastructure are properly installed. Here are a few ways trained technicians can ensure your system works properly:

    • Getting the right size unit – Ever try powering a go-kart with a HEMI? How about a Porsche with a lawnmower engine? Size matters when it comes to HVAC units, and choosing an appropriate unit is key to reducing energy costs and ensuring the longevity of your system.

    If your HVAC system is too large, you’ll experience temperature swings and hot and cold spots throughout your home or business, as well as high humidity and over-sized utility bills. If your unit is too small, it will struggle to reach desired temperatures on hot Tampa summer days. The increased workload on the small system will likely cause it to wear out well before its time.

    Qualified contractors will follow Air Conditioning Contractors of America guidelines to determine the heating and cooling load for your home or business. Once that’s done, they’ll select an appropriately sized unit.

    • Duct installation – Your HVAC systems ducts carry the hot or cold air it is generating throughout your home, heating or cooling rooms as needed. Poorly installed ductwork will lose hot or cold air, forcing your system to work harder to achieve desired temperatures. Energy Star estimates that 20 to 30 percent of the air moving through ducts is lost . Poor installation is a cause of this loss, as well as pinhole leaks that can occur in ductwork over time.

    technician fixing pipes

    Qualified contractors will ensure that ductwork is designed and installed in a manner intended to maximize efficiency. They will also seal ducts as needed to prevent leaks. After installation, a good contractor will also inspect the system to ensure that it is airtight.

    • Getting the refrigerant right – Refrigerant is the medium that moves heat through your HVAC system, removing heat from the air inside the home. HVAC units need just the right amount of refrigerant to ensure optimal performance. If not enough refrigerant is present in the system, it will have reduced cooling capacity and be inefficient. Over time, it can put increased wear and tear on the system as it works harder to cool than it should.

    If a system is overcharged, the operating pressure will be incorrect and refrigerant slugging can occur. Refrigerant slugging occurs when liquid enters the compressor instead of vapor and can cause severe damage to the compressor.

    monitoring gas

    • Ensuring proper clearance – Part of your outdoor unit’s job is to release heat extracted from the air inside your home and business into the outdoor air. It can’t do this if it’s obstructed by flora outside. Rain runoff or falling ice or snow from roofs may also damage the unit.

    Your air conditioning and heating contractor must ensure the unit is properly placed outside. The unit should be well enough away from roof and gutter overhangs to protect it from falling objects or debris and trees and shrubs around it should be cleared to prevent obstruction.

    How Do I Recognize a Faulty Installation?

    If your HVAC unit is malfunctioning or if your heating bills are inexplicably high, a faulty installation may be the root of your problems. Checking these components can help you better inform qualified HVAC technicians about your problem, allowing them to determine its cause more quickly.

    • Make sure you have the right unit – Record any product information about your unit, such as manufacturer and product number, and also determine the square footage of your home. A quick online search can help you estimate whether your unit is too large or too small for your home. If you can’t figure it out, relay the information that you’ve gathered to an HVAC technician, who can make a determination.
    • Check out the ducts – Leaky ductwork is often the culprit in installation failures. Where you can, check your system’s ductwork for any leaks or loose connections. If you see one, make a note of it and inform a heating and air conditioning repair professional ASAP.
    • Watch your bills – If you’ve just purchased a new unit, you can often determine if it was installed improperly by monitoring your energy bills for a few months. If your bills are higher than they were with your old system, and you’re not using it more, chances are that something is very wrong with your new unit or its installation.
    • Check your unit – Give your HVAC unit a visual inspection. Check to see if it appears to be too close to your home or if it doesn’t look like it’s properly set up. If you see something that looks odd, be sure to report it to an HVAC professional.

    Improper installation won’t be the cause of every malfunctioning or under-performing HVAC unit. If your unit is more than 15-20 years old, chances are that the age of the unit has more to do with the problem than installation issues. Regardless of the cause of the issue, getting the problem fixed quickly before it costs you more money is important. To ensure the job is done right, you need to pick a qualified contractor.

    Choosing a Contractor

    When choosing a heating and air conditioning repair service, it pays to hire a contractor with good training and experience. Your contractor should employ technicians who have undergone thorough trade school or on-the-job training in HVAC systems and who are knowledgeable about the latest units on the market. Your contractor should also have relationships with trusted name-brand HVAC unit manufacturers and should be able to discuss the design and quirks of your unit’s manufacturer.

    hvac unit maintenance

    Word-of-mouth is often the best way to find a qualified HVAC repair and installation company. Ask your friends and neighbors who they’ve used and who they recommend. You can also get a good feel for a contractor’s abilities and areas of competence by checking out online reviews.

  • Should I Replace My Furnace at the Same Time as My Air Conditioner?

    Here in Tampa and other areas of central and south Florida, it largely will depend upon the type of heating and cooling system used in your home. Many homes have what is known as a “packaged system” or all-in-one air conditioner/heating solution.

    This type of system has most of the parts and components required to cool and heat your home contained in a single unit. They are beneficial because they eliminate the need to have a split system, where one part of the air conditioner (AC) is outdoors, the furnace is indoors, and they share the same blower and air handler indoors.

    hvac technician

    With a packaged system, you can use that extra space inside the home for a pantry, laundry room, or other purposes. Even if you have an existing split-system, and it is time to replace the furnace and AC together , you may want to consider a packaged system instead of separate units.

    If you have a packaged system and something goes wrong where the unit needs to be replaced, then, yes, you will need to replace your furnace and AC at the same time. However, if you have a split system, then, in certain cases, you may be able to replace the AC but not the furnace and vice versa (replace the furnace, but not the air conditioner).

    When Should You Replace Your AC and Furnace?

    Your AC and furnace will eventually need to be replaced with a new system. One telltale sign that it is time for a new furnace or AC unit is when heating and AC repair is becoming a monthly occurrence. This is a good indication the system has reached the end of its usefulness. Rather than continue to spend money on monthly repairs, it makes more sense to buy a new system.

    The average lifespan and usefulness of heating and AC systems vary, but a good general timeframe is:

    • 15 – 20 years on packaged systems
    • 20 – 30 years on furnaces (split systems)
    • 10 – 15 years on air conditioners (split systems)

    Most people will attempt to push their existing systems to the upper limits before replacing them. Part of this has to do with the costs associated with getting a new system.

    furnace system

    However, in more recent years, as technological improvements have made home heating and cooling systems much more energy efficient, we are finding people are replacing their systems when they are between 10 and 15 years old. This allows them to take advantage of the newer efficiencies and increased energy savings.

    You should also consider replacing your AC and furnace if you notice your energy bills are increasing. This could indicate the system is no longer operating at peak efficiencies. A tune-up from one of our AC and heating repair technicians might help if your system is not that old.

    On the other hand, if it is getting up there in years, then a tune-up is only a short-term fix. Eventually, you will need to replace the system, as tune-ups will no longer help maintain the system’s efficiency.

    Benefits of Replacing Both at Once

    The most obvious benefit of replacing both your AC and furnace at the same time is you will have a “matched” split system. This means all of the parts and components used indoors and outdoors are designed to work together to provide maximum operating performance and energy efficiencies.

    With an “unmatched” system, where you replace only the AC or the furnace, the maximum efficiencies output by the new part of the system may not be able to be fully reached. This will largely depend on the age of the other part of the system you are not replacing.

    new furnace units

    Another benefit of replacing both units at the same time is you may qualify for a special rebate, incentives, and offers by the system manufacturer. Home heating and cooling unit manufacturers often run different promotions, much like car manufacturers, so you will want to inquire what current incentives are available.

    In addition, your home heating and cooling sales and installation company might provide a discount since you are purchasing both at the same time. For instance, the costs to replace just the furnace could run between $2,000 and $5,000, depending on the model and features.

    However, if you were to get a new furnace when you had your AC replaced, the costs to add this on could range from $1,000 to $3,000. Please keep in mind, this is just an example to illustrate how you could save money by doing both at the same time, and your actual savings and costs can and will vary.

    Other Reasons to Replace Both at Once

    Aside from aged systems and potential cost savings, there are other times when it makes sense to replace both your AC and furnace at the same time, as follows:

    • The installation of the new system poses specific challenges that make the job difficult. If the furnace or the blower and air handler are in hard-to-access areas, you may want to do both at the same time.
    • You live in a remote rural area. If you are already having a technician come out to replace your AC or furnace, and you know the other one will need to be replaced in the near future, it is better to get both done at once.
    • You want to upgrade to an HE (High-Efficiency) AC model. If you are looking at new AC units with a 16 SEER rating or higher, then you will want to get a new furnace at the same time. This is because these HE units have to be matched to a compatible furnace model. These types of systems require variable speed motors and other modern technologies to operate correctly.

    You are getting ready to retire. Once you retire, if you are like most retirees, the last thing you want to worry about is having to buy a new AC or furnace on a fixed income. Replacing both now allows ensures you will not have to worry about this expense for the next 10, 15, or 20 years.

    hvac repair

    Times When You Will Not Want to Replace Both

    There are a few times when you may not need to replace both the AC and furnace at the same time. These exceptions apply to split systems, not packaged systems.

    • The AC unit is less than 5 years old. Split system AC units will last between 10 to 15 years, on average. So, if you are replacing the furnace and not converting from a split system to a packaged system, then it can be better to wait.
    • The furnace is less than 10 years old. Furnaces on split systems last between 20 to 30 years, on average. Since furnaces have almost double the lifespan of AC units, it makes more sense to wait and replace both the next time the AC unit has to be replaced.
    • A salesperson told you to replace both. If you went shopping for a new AC unit or furnace at a showroom, the salesperson may have said you had to do both at the same time. The reason they said this is partially because they are working off a commission, so, if they can sell you both, they earn more.

    If you know you need either a new furnace or AC and are not sure if you should replace both, the best thing to do is to contact us and have one of our licensed, bonded, and insured HVAC technicians take a look at your system. Our technicians will let you know if you can wait on one or the other or if it would be better to replace both now.

  • 11 HVAC Must-Dos Before You Leave on Vacation

    You’ve boarded the pets, asked the neighbors to get the mail, and turned off all your appliances and lights. You’ve taken care of everything, and now you can enjoy a few weeks of well-earned vacation away from the hassles and tasks at home.

    Not quite. Before you hit the road, there are a few things you need to do regarding your HVAC system to keep it in good shape and ready to resume service when you return. At the end of your vacation, the last thing you want to do is return to a hot, sweltering home and a big heating contractor bill because you failed to take a few simple precautions before leaving on your trip.

    vacationing on the beach

    Your HVAC unit is one of the most complex pieces of machinery in your home. It’s also one of the biggest consumers of energy, accounting for about 48 percent of energy use in the typical home in America, and likely even more in hot and humid areas like Tampa. Properly maintaining it when it’s in use and during periods of dormancy such as vacation travel will help preserve the longevity of your unit and help you keep your energy costs down.

    Vacation HVAC Checklist

    Before your next vacation, be sure to take care of these tasks to keep your unit in good repair and to lower energy costs while you’re gone:

    • Turn it down, don’t turn it off – Contrary to popular belief, you shouldn’t completely shut down your HVAC unit while you’re gone. HVAC units are designed for regular usage, and when they are inactive for long periods, important components can deteriorate and operate at diminished capacity when put back into regular use. Also, when your HVAC isn’t active for long periods of time, moisture can build up in your home, creating conditions where mold can flourish.
    • When preparing to leave your home for a vacation, turn your thermostat up by about five degrees. Your unit won’t run as often as it does when you’re there, and the need for a comfortable temperature is paramount, but it will run enough to prevent moisture buildup and to provide sufficient activity for the system. Experts say the ideal temperature to turn up your unit to in the Tampa area is around 80 degrees.

    • Change the air filters – Under normal conditions, you should change your air filters once a month to prevent them from becoming clogged. While you’re gone, your HVAC unit will be running less often, and dirt and dust will have less of an opportunity to build up on the filters.
    • You should still pop a fresh one in the unit before you leave to ensure the unit has the best possible protection from dirt and dust while you’re away. If you’re leaving for an extended vacation of several months, it may be worthwhile to have a neighbor or your regular ac maintenance technician change the filter a few times during your absence.

    • Prepare for adverse weather – Tampa is prone to storms during the summer, and these storms can cause damage to an HVAC unit. The most likely cause of storm damage to an HVAC unit is that of downed trees and limbs. Before leaving on vacation, inspect the area around your unit to see if there are any limbs hanging over it. If there are, remove them. Also, clear the area of underbrush and other objects a storm could cause to collide with your unit.
    • Give your home a good vacuuming – Dust and other contaminants will accumulate while you’re gone and will circulate through your HVAC system. Reduce the amount of dust and allergens available to accumulate by giving your home a thorough vacuuming and cleaning before you leave for vacation.

    home vacuum cleaning

    • Ensure sufficient airflow to your outdoor unit – Good airflow is essential to the operation of your HVAC unit. When the outdoor unit’s air intake is clogged, it has to work harder to perform, consuming more energy and putting more wear and tear on the device. Before leaving on vacation, check the intake on your unit and clear any leaves, limbs, or grass clippings from it.
    • Make sure all windows are closed – Closing all the windows will reduce the amount of hot air entering your home, causing your unit to run less often. It’s also just good common sense from a security and safety standpoint.
    • Close all your blinds and curtains – Blocking sunlight from entering your home will reduce the temperature inside, thus reducing your unit’s workload. You’ll want to make sure that there’s no direct sun shining on your unit’s thermostat, as this can cause it to indicate the room is hotter than it actually is, resulting in increased usage of the unit.
    • Make sure the unit isn’t leaking – A leaking unit is the sign of a serious problem. If your unit is leaking, resolve the issue before you leave for vacation. An AC technician can quickly diagnose the problem and make a fix, averting the likelihood that the leak will result in the system failing. Replacing a system is much more expensive than fixing one, in most cases, so you’ll need to take care of this problem ASAP.

    vent check

    • Make sure all vents are open – Open all the vents in your home to ensure that air flows throughout the system and your house. HVAC systems are designed to operate with maximum airflow, so opening the vents will allow the system to operate in optimal conditions while you are away.

    condenser coils

    • Clean your system’s condenser coils – Your outdoor condenser coils are vital to the operation of your system. Condenser coils take heat collected from your home and release it into the outdoor air. When condenser coils are dirty, they won’t function at peak efficiency.
    • You can easily clean your condenser coils with water and coil cleaner but, if you’re not comfortable with doing this, you can get an firm to handle the job for you. If you clean the coils yourself, be sure to turn off the power to the unit before beginning work.

      Keeping your coils clean is one of the most helpful things you can do to reduce energy consumption. According to the Department of Energy, dirty coils can increase the amount of energy needed to run your unit by about 30 percent . Giving the coils a good cleaning before leaving for vacation helps ensure they don’t accumulate debris and dirt that can hinder their effectiveness.

    setting thermostat

    • Use a smart thermostat – If you haven’t invested in a smart thermostat yet, now may be an opportune time. Smart thermostats allow you to program your thermostat to run at certain times or maintain certain temperatures. Many can be managed remotely from your mobile device.
    • Smart thermostats are great for people who own multiple vacation properties, as they can adjust those properties’ thermostats remotely for reduced use when guests aren’t in residence. For vacationers, a smart thermostat can ensure that they don’t return to an uncomfortably hot home.

    By taking appropriate steps before they hit the road, vacationers can avoid expensive A/C repair bills when they return. Homeowners can also avoid expensive repair work by entering into service agreements with reputable ac repair and maintenance companies. These contracts provide regular service, such as inspections, coolant recharging, duct cleaning, and more and can help homeowners avoid having to replace their units too early.

    Air Rescue is a Tampa HVAC repair and maintenance firm offering a wide range of services, including ac repair, ac maintenance, duct repair and replacement, total system rejuvenation, and furnace repair and replacement. For comprehensive care from a firm with the experience and expertise to handle all problems, contact Air Rescue today.

  • Life Before HVAC: Short & Unbearable

    If you visit Tampa’s historic Fort Brooke in the summer, the first question that will likely come to your mind is, “How did the early explorers stand this heat without air conditioning?”

    modern hvac thermostat

    There’s a good reason why Florida’s population didn’t explode until the mid-20 th century. Before air conditioning became widespread, the state was simply too hot and muggy to make it a comfortable place to live. Once air conditioning became an affordable technology and HVAC technicians began installing systems throughout homes in the state, Florida was finally able to realize the potential offered by its beaches and (at the time) low land prices.

    Air conditioning has had a major impact on human health and development around the world, allowing people to live in previously uninhabitable places and providing the comfort necessary to extend human life and increase productivity. Today’s modern HVAC units aren’t the only way humans have tried to control their climate over the centuries, however. Throughout history, humans living in hot climates have employed a number of technologies to cool their homes and other buildings.

    • Ancient Egypt – Pharaohs of Egypt cooled down thanks to the sweat of others. Artwork from the period shows rulers and other high nobles being cooled by large fans waved by servants. Fans were often made from the feathers of large birds.

    • Ancient China – In second century China, inventor Ding Huan developed a novel method of cooling a room. Huan developed a manually powered rotary fan that incorporated seven wheels into its design. Later Chinese inventors extrapolated on Huan’s design. During the Tang dynasty, Liang Tian developed a water-powered rotary fan system.
    • Ancient Rome – Many wealthy Romans cooled their homes by using water from the city’s aqueduct system to circulate cool water through the walls of their residences. Fabulously wealthy Romans went to greater extremes. The emperor Elagabalus imported tons of snow via donkeys from nearby mountains and piled it up next to his villa to remain cool in the summer.

    • Medieval Persia – In medieval Persia, builders created a novel way of cooling buildings by harnessing the abundant wind resources available there. The towers used windows for capturing winds. Internal vanes inside the towers funneled cooler air into buildings below and pushed warm air out of the buildings. Architecturally gorgeous, many of these towers still stand throughout the Middle East and are still functional.
    • Colonial America – Famed inventor Benjamin Franklin played a role in developing the technologies that later gave rise to the modern air conditioning unit. Franklin and a friend, John Hadley, worked together on experiments involving the evaporation of alcohol and ether to reduce temperatures. Franklin and Hadley evaporated alcohol and ether and lowered the temperature of a mercury thermometer from 64°F to 7 °F. As any HVAC technician can tell you, evaporation of coolants plays a major role in modern cooling units.

    • 1800s America – One of the early applications of electricity was powering rotary fans. Water and steam-powered rotary ceiling fans began appearing in the early 1860s and 1870s in the U.S. In 1882, electric fans began appearing in homes and businesses.
    • 1900s America – By the 1920s, ceiling fans became commonplace in the U.S. By the 1960s, they fell out of vogue as air conditioning became widespread in the U.S ., but remained popular internationally, particularly in countries where the electrical infrastructure was not sufficient to support the level of energy consumption required by AC units.

    Ceiling fans experienced a resurgence in popularity in the 1980s when energy efficiency became a major concern in the U.S. Today, many homes use ceiling fans along with AC units as an energy efficient cooling solution.

    The Development of Air Conditioning

    What we recognize today as an HVAC unit was developed in the early 1900s by inventor Willis Carrier. Carrier developed a machine that sent air through water cooled coils. Carrier’s machine wasn’t intended to cool homes and buildings—Carrier was trying to control humidity in a printing plant where he was employed.

    Carrier saw the potential in his device and made further innovations, and today’s units which use pressurized coolants to remove heat from buildings were the eventual result. Other manufacturers continued refining the concept. Frigidaire developed a split-system room cooler in the 1920s, and General Electric later refined this design, developing a self-contained room cooler.

    In the 1930s, manufacturers began combining the concepts pioneered by Carrier with refrigeration technology to create what we recognize today as air conditioning units. General Motors engineers began using chlorofluorocarbon coolants to create a system that cooled buildings by moving heat from inside to the outside.

    In the early days of air conditioning, HVAC units were prohibitively expensive and only the very wealthy home and business owners could afford them. In the early part of the 20 th century, people often flocked to their town’s movie theater in the summer months as it was often the only place in town with air conditioning that could accommodate a large crowd.

    Time and continued developments in the technology made air conditioning increasingly accessible to the public. In the 1940s, Henry Galson developed a window air conditioner which became the first successful window unit product, selling 43,000 systems by 1947. As the technology continued to develop, new home construction increasingly incorporated central air conditioning into their design. By the end of the 1960s, most new homes had central air conditioning.

    commercial air ducts

    Today, about 87 percent of homes in the U.S. have air conditioners . The rise of air conditioning has made cities in the South and West more comfortable and contributed to a shift in U.S. population from the Northeast and Upper Midwest.

    Work continues to make HVAC more energy efficient and reduces its environmental impact. Today, the average household spends about 48 percent of its monthly power bill on heating and cooling costs. Environmental concerns led to the industry abandoning chlorofluorocarbons, but concerns remain about the replacement coolant, hydrofluorocarbons. Research continues into the use of non-vapor compression technology, which will have less of an impact.

    Government regulations have helped to increase efficiency. Since 1992, the U.S. energy department has mandated energy conservation standards. Experts say the standards will result in about $29 billion in energy savings from 1993 to 2023. New standards enacted in 2006 are predicted to yield $70 billion in savings between 2006 and 2035. Thanks to developing technology and the regulatory push, today’s air conditioners use half the energy they did in 1990.

    Benefits of Air Conditioning

    Air conditioning certainly makes life more comfortable and has allowed people to live and work in parts of the country that were previously not very appealing because of the unrelenting heat. In addition to comfort, air conditioning has some very positive health benefits, including:

    • Easing respiratory symptoms. Many people with asthma and allergies do much better in air-conditioned environments with air filtration systems.
    • Reducing heat-related stress on the body, which is helpful to people with chronic conditions such as multiple sclerosis.
    • Dehumidifying air. Air conditioners can help dehumidify the air in your home, which reduces the likelihood of mold growing in your home. Mold contributes to many respiratory illnesses that can be serious.

    When looking for a reliable AC contractor to install and maintain your heating and cooling system, it’s important to find a company with a track record of success.

    Air Rescue is a Tampa AC maintenance and repair company . In business since 1946, the company has built a reputation for technical expertise and top-notch customer service. Air Rescue’s staff is highly trained, and the business offers a membership plan that provides customers with two annual maintenance checks, guaranteed response times, and deep discounts on repairs.

  • Seven Ways Tampa Residents Can Save on Summer HVAC Bills

    Tampa residents can always count on a spike in energy bills and other costs related to keeping their homes cool during the sweltering summer months. If cooling costs are making a huge dent in your monthly budget, it may be time to make some investments of time and money that will create greater savings in energy and AC maintenance costs in the long run.

    Tampa has a humid, subtropical climate, and the city stays hot from May through October. Even the winter months will have a few days where you’ll need to turn on the air conditioning. Seasonal highs for the summer months have average highs in the 90s and lows in the 70s. The high humidity makes the heat even more uncomfortable.

    Because temperatures in Tampa get so high, and because the city has an extended hot season, residents can end up spending quite a bit of money on keeping their homes and businesses cool. Not all this expense is necessary, however, as inefficient habits and home and HVAC maintenance needs can drive up energy bills in the summer. Smart property owners can lower their bills by adopting some new behaviors and making a few needed changes to their home and business property.

    According to the U.S. Department of Energy, air conditioning accounts for about 48 percent of the average home’s energy consumption . A great deal of this energy is wasted on cooling empty homes or operating inefficient HVAC units. By optimizing your home and your habits, you can shave a significant amount off your energy bill. Good AC maintenance practices can also save you money by extending the life of your HVAC unit.

    Ways to Save on Summer HVAC Costs

    For homeowners looking for ways to save on their summer cooling bills , these tips make a great starting point:

    • Turn the thermostat up – Perhaps the easiest way to reduce cooling-related energy costs is to use your unit less. By maintaining a slightly warmer temperature in your home, you can save a significant amount on your heating bill. Wearing lighter clothes, such as thin shirts and shorts at home will help you avoid getting too hot from a higher setting on your thermometer.

    energy efficient hvac thermostat

    avoid turning your thermostat to a cooler-than-usual setting when you turn it back on after having it turned off for a while. It won’t make your home cool more quickly, and will just result in a cooler-than-comfortable room and added energy expense.

    • Use a ceiling fan – Ceiling fans can make a room feel six to seven degrees cooler, thanks to the wind chill effect. On moderately warm days, you can get away with using just fans for cooling. On hotter days, you can use them along with your AC unit. You won’t have to work the AC unit as hard to reach a comfortable temperature, saving you energy, as ceiling fans use less electricity.
    • Install a dehumidifier – Humidity makes your HVAC unit work harder to cool your home. In very humid parts of the country like Tampa, this can be a big problem. Adding a dehumidifier to your unit will help with this problem. You can have an air conditioning contractor install a dehumidifier on your HVAC system to better manage humidity levels in your home. Most experts recommend maintaining a humidity level between 40 and 60 percent in your home for maximum comfort.
    • Install a smart thermometer – How often are you away from your home for hours, but still leave the air conditioner running? A smart thermometer can help you avoid spending money to cool an empty home. These thermometers can be programmed to operate only during certain hours, and some can even learn your daily routine and run the unit accordingly. Some even have a convenient feature that allows you to control them remotely from your smart phone, ensuring that you don’t waste energy while you’re at work or away from home, but never come back to an uncomfortably warm home, either.
    • Install solar screens or window films – Solar screens are less expensive than installing new windows and can help intercept up to 70 percent of solar energy before it enters your home. Experts with the U.S. Department of Energy say these screens are helpful for east and west-facing windows. Window films can also block solar energy. These thin, metallized sheets reflect heat before it can penetrate window glass.

    In addition to these methods, you may also wish to install sturdy curtains and blinds in your home to reduce the amount of solar energy making its way through your windows.

    • Have your HVAC unit serviced – An inefficient or improperly operating HVAC unit will cost you in energy bills. There are a variety of things that can go wrong with an HVAC unit that can run up your energy bill, such as improperly operating fans or malfunctioning condensers. According to the Department of Energy, about 20 or 30 percent of the air moving through the ducts of a typical home is lost through leaks in the duct work. Hiring an air conditioning contractor in Largo, FL to come to your home and inspect your unit and ductwork can help you identify maintenance needs that may be running up your power bill.

    • Insulate your home – If you’re living in an older home, it may not be sufficiently insulated. If your home has a garage that was enclosed to create additional space, this space may not have been properly insulated, either.

  • Six Warning Signs Your Air Ducts Need Cleaning or Replacement

    Most people give little thought to their HVAC system’s ductwork until something has gone horribly (and expensively) wrong with it. This is a huge mistake as a little preventative air duct maintenance can go a long way toward keeping your system running efficiently and preserving the indoor air quality of your home or business.

    Let’s face it. Here in Tampa, air conditioning is something you just can’t live without. With average highs in the low-to-mid 90s in the summer and an average daily humidity of around 74 percent , life in Tampa becomes quickly unbearable without a properly functioning air conditioning unit.

    Your air ducts are important infrastructure for your HVAC system. Your ducts provide a conduit for the cool or heated air produced by your HVAC system to flow into the various rooms of your home to achieve your desired temperature. When ducts are obstructed or have leaks, it can cause your system to lose efficiency, running up your energy bill and increasing wear and tear on your HVAC unit.

    Air conditioning repair experts recommend duct cleaning every few years to dislodge dirt and other debris in the ducts. If your ducts haven’t been cleaned in a while, here are a few signs that cleaning is needed immediately.

    Warning Signs Your Ducts Need Cleaning

    • Unexplained spikes in your energy bills – If your bills are climbing and there’s no good explanation for the hike, such as increased usage or mechanical problems with your unit, you may have clogs or leaks in your ducts that are reducing the system’s efficiency. Air conditioning repair services can inspect your ducts to see if this is the problem and take steps to clean and seal your ducts as needed.
    • Signs of rodent or insect infestation – If you see or smell evidence that rodents or insects may be living in your ducts, it’s definitely time to have your ducts cleaned. Debris from these infestations can cause damage to your HVAC system, reducing its efficiency. Over time, the smell from droppings and other debris can also become highly unpleasant. Also, having contaminants from rodent or insect droppings and shells and husks from insects circulating through the air that you and your guests breathe can cause sickness. A rodent or insect infestation in your ducts represents a big health threat, and one you should deal with immediately.
    • Dirt and debris around your vents – If you’re noticing dirt and debris around your vents, there’s a very good chance that your ducts have developed blockages or have a high amount of contaminants circulating through the system. High levels of dirt and debris circulating through your system can exacerbate allergies and other respiratory problems, so it’s well worth your while to have your ducts cleaned.
    • Unexplained respiratory problems – If you or members of your family are having unexplained allergy, sinus, asthma, or other respiratory problems, excessive dirt and debris circulating through your ducts may be the problem. Air cycles through your home about seven times a day, and if your ducts have high levels of dirt and debris, it can have a big impact on indoor air quality. If sneezing and wheezing have become a problem in your home, and if it’s been years since your last duct cleaning, you may want to call an air conditioning maintenance company out to inspect your ducts and clean them.
    • Visible mold growth – Because of Tampa’s humid climate, mold growth is a huge problem here. Mold exposure in homes has been linked to many health issues , some of them very serious. Mold can often cause respiratory issues, eye irritation, throat irritation, and even skin irritation. People with compromised immune systems or chronic lung illnesses may develop serious infections if exposed to mold.

    If you see mold growing around your vents or inside your ducts, do not hesitate to call an air conditioning repair company to perform an inspection and cleaning of your ducts. Mold is more prevalent in Florida than most parts of the country, so homeowners must be constantly vigilant against this serious health threat. Catching mold infestations early before they can spread throughout the home and become difficult to eradicate can help reduce the cost of remedying this problem.

    • Dusty air filters or air return grilles – If your recently installed air filter is covered in dust, chances are that your ducts are clogged and need cleaning. Return air grilles with thick, fuzzy coatings of dust are also indicators of a duct problem.

    How Ducts Are Cleaned

    Professional duct cleaning services can provide a thorough cleaning far beyond what the average homeowner can do on his or her own. Air conditioner maintenance service technicians have specialized tools and training that allow them to remove nearly all dust and contaminants from duct work, even in the most hard-to-reach places.

    When duct cleaning services visit your home, they’ll often inspect the unit and ducts. Technicians will use small cameras to check the more inaccessible areas of the ducts. After inspection, technicians will use specialized brushes and tools to loosen debris within your ducts.

    Next, they will use a vacuum to remove dirt and debris from the ducts. They will also likely clean the cooling coils and the blower unit. Your technician may also decontaminate your ducts with germ and odor-killing compounds. In addition to cleaning the ducts and other parts of your unit, your technician will also clean grilles and vents.

    If your technicians detect leaks in your ducts, they may offer to seal these leaks. It’s well worth your while to have leaks sealed, as the U.S. Department of Energy estimates that 20 to 30 percent of the air that moves through your home is lost through leaks in your duct work. A properly sealed duct system can reduce air loss, thus reducing the amount of work your HVAC system must do to maintain comfortable temperatures in your home.

    Taking care of your ducts can reduce your power bills and increase the longevity of your HVAC system by reducing its workload. As new HVAC systems can cost thousands of dollars to install, keeping your system running efficiently for as long as possible can save you lots of money. Regular cleaning of your HVAC ducts can also greatly benefit the indoor air quality in your home or place of business.

    Poor indoor air quality is being increasingly linked to a variety of illnesses , and modern home design has made maintaining good indoor air quality difficult because new homes are so tightly sealed for energy efficiency purposes. Cleaning your ducts can help keep mold and contaminants from constantly recirculating through your home and giving rise to respiratory and other illnesses.

    When hiring a company to perform air duct cleaning services, make sure you hire a professional company with the tools, training, and experience to do the job correctly. Check online reviews and ask your friends and neighbors who they use for air conditioner service. Talk to prospective service providers about their professional credentials and experience. Also, don’t be afraid to ask prospective providers for references.
