• Why Your AC Blows Warm Air

    Your air conditioning unit has one job: to blow cold air. When it suddenly stops doing that, it’s not just uncomfortable, it’s downright annoying. What would cause an air conditioner to blow warm air? Is it something that’s easy to rectify, or do you need to call in a professional to fix it?


    The first thing to check is your thermostat. If your thermostat has accidentally been set to heat, it will definitely cause warm air to blow from the vents. On the other hand, even if your system is set to cool and not heat, if it’s turned to “on” instead of “auto”, it means that your system will be blowing air all the time, whether or not the air conditioner is actively cooling that air. It’s better to keep it on the “auto” setting so that the system will run more efficiently.

    If the thermostat isn’t the issue, something may need cleaning. Have you been changing your air filters as often as you should? Most filters should be changed monthly, and if you don’t keep up with that small maintenance step, the filter can become dirty and clogged. This will block the air circulation in your system, which could cause it to blow warm air. Another component that may require cleaning is the evaporator coils. You can clean these yourself, by turning off your AC, removing the outer panel, and cleaning the coils with compressed air, a brush, mild detergent, or a commercial cleaner. On the other hand, it may be easier to call in a professional to do the job.

    Don’t forget that part of your HVAC system is outside. If the outside condenser unit isn’t properly maintained, it may be causing the problem. Go look at it and see if something is blocking the condenser coil’s air flow, like dirt or debris. It’s important to maintain the outside unit, cleaning the condenser coils during the summer as often as necessary. Another problem that can occur with the outside unit is a loss of power. Even if the indoor part of the HVAC is working, if the outside unit has lost power, the air won’t be cold. Check to see if a fuse has blown or a circuit breaker has been tripped, and call a professional immediately if this is the case. It could indicate a serious problem with your air conditioner.

    Electrical issues can be a problem. Running an air conditioning unit requires a lot of power. If any part of your unit isn’t receiving electricity, the whole unit can malfunction. If you suspect an electrical problem, call for a repair immediately.

    Your ducts may also be causing the problem. Sometimes, ductwork gets knocked out of place and becomes disconnected. When that happens, it’s no longer sealed, and it can let hot air into your house. Call a professional HVAC technician, to ascertain whether your ducts need to be repaired or replaced.

    Your system may need refrigerant/Freon. The way that your air conditioning system cools the air is by moving refrigerant, usually Freon. If there’s a leak that’s allowing this refrigerant to escape, the AC will stop blowing cold air and start blowing warm air. Other signs of leaking refrigerant include ice forming on your AC unit, and a buzzing or screaming sound. If you suspect you have a Freon leak, call for professional assistance immediately, as refrigerant can be harmful to your family’s health.

    Of course, the best way to ensure that none of these problems disrupt your summer air conditioning is to keep your system in good repair through regular maintenance. As already discussed, part of this is keeping your outside unit free of debris and changing your air filters regularly. Another big piece of the puzzle, though, is professional preventative maintenance. Each spring, before you crank up your system for the first time in the summer, have an HVAC professional come out to check your unit for problems and make sure everything is in good working order.

    During this maintenance visit, the HVAC technician will inspect the belts, thermostat, and refrigerants, and check for duct leakage. He or she will also perform services like blowing out the lines and checking the safety controls. The technician will tighten electrical connections, lubricate the moving parts, and check and inspect the condensate drain. In addition, the evaporator and condenser air conditioning coils will be cleaned to help the system work more effectively. Any adjustments that need to be made to your system to help it work efficiently will be done, and parts that are preventing it from working the way it should will be replaced. Your HVAC professional can also advise you on any other work that should be done, such as cleaning out the air ducts. If your system needs an upgrade, your technician can offer advice on that as well.

  • How to Reduce Indoor Pollution

    When you think of air pollution, you’re probably thinking about factories and cars, sending dangerous emissions up into the ozone layer. You may not immediately consider indoor air pollution, but if you think about it, it’s definitely a threat to your well-being. The contaminants inside our homes and offices put us at risk for allergic reactions and illnesses that include stroke, heart disease, COPD, and lung cancer. Fortunately, you can improve your indoor air quality by following a few simple guidelines.

    • Know the culprits. What are the causes of indoor air pollution? In developing countries, dangerous indoor air quality is the result of people cooking indoors, using inefficient stoves with fuel like kerosene, biomass, or coal. In the United States, though, the sources are more likely to be things like fragrances, cleaners, smoking, or pets. Taking a critical look at your home and work environments in order to determine what could potentially cause problems is the first step toward cleaner air.
    • Keep your smoke outside. Smoking cigarettes causes a wealth of health problems, both for the smoker and for those who breathe in the second-hand The best thing you can do for your health and your environment is to quit, but if you must smoke, do it outside. Other sources of smoke should be used with caution, too. Don’t overdo it with candles, and if you use a wood-burning stove, make sure it’s installed properly and well-ventilated.

    • Maintain proper ventilation and moisture levels. You can often improve air quality the old-fashioned way, just by opening a window. When you cook, use the fan above the stove, and when you shower, use the fan in the bathroom to reduce moisture in the air. You might also consider a dehumidifier or an air purifier with high-efficiency particulate arresting (HEPA) air filters.
    • Cut down on chemicals. Every day, we use all kinds of chemicals without giving them much thought. From air fresheners and candles to household cleaners to personal care products, to paint and solvents, there are a host of pollutants in your home that you probably don’t even realize are a problem. Many of these products contain phthalates, which are used to make the fragrances bond to the product in which they’re being used. Unfortunately, phthalates have been shown to disrupt the endocrine system. Does this mean that all fragrances are bad? No, but if you really love giving your house an extra boost of scent, you’re better off sticking to essential oils or simmering some spices on your stove.
    • Clean the house. How will you clean the house, while eliminating chemicals and fragrances? It’s easier than you might think. Look for all-natural, non-toxic cleaners, or make your own cleaners, using ingredients like borax, vinegar, and baking soda. Ditch the carpet, if possible, and clean your floors with a steam mop: steaming your floors requires only water. Dust frequently, and keep clutter to a minimum. Wash your bedding and any washable stuffed animals regularly, cleaning these items once a week in hot water, and vacuum your upholstered furniture when you clean your floors. Skip curtains and drapes, opting for window treatments that can be wiped clean.
    • Keep contaminants out. Make a rule in your home that people remove their shoes at the door. If you’re not comfortable doing this, at least have a sturdy doormat that can scrape most of the contaminants off before they’re tracked into your house. If you have pets, keep them well-groomed, and vacuum frequently to reduce pet dander in the house.
    • Be smart about safety. Have your home tested for radon, a colorless, odorless gas that can significantly raise the risk of lung cancer. Many items give off radon, including granite countertops, so it’s important to know that your home is safe. Radon is not the only dangerous chemical that may be in the air, though, so install a carbon monoxide detector, and keep your household appliances in good repair, so that they don’t leak any fumes into your atmosphere.
    • Bring in some greenery. Plants are great for improving indoor air quality, and studies have shown that they even reduce levels of formaldehyde in the home. The roots and the foliage work together to absorb chemicals released from synthetic materials in your home, while the plants themselves give off oxygen, improving our air quality.
    • Maintain your HVAC system. Change your filters regularly, and call in a professional when the seasons change, to give your system the maintenance it needs to keep it running efficiently.

  • Answering Questions About Duct Replacement

    You may think your air ducts only need an occasional cleaning, but there are times when you will need to call your HVAC contractor for a duct replacement. Let’s look at the answers to some common questions about duct replacement and other AC maintenance in Tampa and St. Petersburg, FL. Checking - Air - Flow

    Should my ducts be replaced or cleaned?

    Determining whether your ducts should be cleaned or replaced is up to your HVAC contractor. A duct cleaning is often sufficient to solve any duct problems. However, there are times when a contractor will suggest a duct replacement over a cleaning. If your ducts show significant damage—from mold growth and other factors—or ducts have collapsed, then your contractor will likely suggest a duct replacement. If your ducts are found to have been improperly installed or designed, then you may need a replacement instead of a cleaning. A replacement can ensure that these problems do not return and that the installation was done correctly.

    When should my ducts be replaced?

    If your ductwork or your house was constructed several years ago, then you may need duct replacement. Even with proper cleanings, ducts can eventually degrade, or past materials may not be as efficient as newer materials. Your HVAC contractor should inspect your ducts to determine if they need to be replaced. He can also look for signs of extensive mold growth, which may be another sign you should have your ducts replaced. Dirt, dust, and some mold is to be expected in all ductwork. If it is extensive, however, then you could risk further damage to the ducts or health problems for your family.

    When should my ducts be inspected?

    Your ducts should be professionally inspected and cleaned every two to five years. However, there are some signs that can signal the need for inspection. If you notice your utility bills are rising, or your HVAC system is degrading quicker, then you may have leaky ductwork. Watch out for these signs to call your HVAC company for a professional duct cleaning and inspection.

  • Tips for Choosing a New Furnace Filter

    A furnace filter will usually only cost you a few dollars, but it’s one of the most important investments you will make when comes to maintaining your HVAC system. Your furnace filter stops dirt, dust, debris, allergens, and other contaminants from entering your HVAC system, and it can prevent the need for furnace repair in Tampa down the line. It’s why you should make sure you replace your furnace filter at least once every few months, if not sooner. Here are some tips for choosing the right furnace filter for your home.

    Furnace Filter

    Select a furnace filter based on how clean you want your home’s air to be.

    Do you have allergies, or does someone in your family suffer from them? Or do you have a pet that sheds a lot? If so, you probably want to look for a furnace filter that is designed to filter out allergens and pet dander. It will help your HVAC system as a whole and keep your home’s air cleaner. If you don’t need to worry about things like allergies or pets, though, you might not necessarily need a furnace filter equipped to filter allergens and dander. It really all depends on what you need to filter out of your home’s air. Make sure you buy the best possible furnace filter for your specific situation.

    Find out the MERV rating of a furnace filter before buying it.

    MERV stands for “minimum efficiency reporting value.” It’s a rating that determines how effective your furnace filter is , and every furnace filter on the market should have a MERV rating that’s clearly labeled. The higher the MERV rating, the better, so when you are shopping for a new furnace filter, look for this rating.

    Steer clear of relying on a reusable furnace filter that requires extensive maintenance.

    Reusable furnace filters sound like a good idea in theory, but many of them are difficult to clean. If you are prepared to maintain them properly, they can be effective, but most homeowners opt to use disposable furnace filters that are easy to replace in their furnaces.

  • Why is my AC unit not cooling?

    Tampa AC Maintenance An HVAC air filter is an essential element for climate control in any home. It helps keep air quality pure and well ventilated. It also helps keep heating and air conditioning units’ air flow running properly. Filters are an easy thing to change and can dramatically improve the air quality in a house.

    It’s not always easy to remember to change an HVAC air filter. After all, it’s out of sight, out of mind, and there’s no official expiration date set for air filters. A good rule of thumb is to change an air filter whenever it gets dirty. How fast an air filter gets dirty will change based on a various factors. For example, how many people live in a home, if pets live in a home or how much dust is in a house can dramatically change how fast the air filter gets clogged up. The quality of the filter itself will also alter how long it can go before needing a change. Under no circumstances should an air filter go an entire year without being changed.

    Changing an air filter has several built-in benefits.

    The main purpose of the filter is to clean the air of airborne particles like pollutants, allergens and dust. Without these particles floating around, it’s easier to keep the house clean and it can help reduce allergic reactions to things like pet dander or pollen. Breathing clean air can help homeowners sleep better and reduce chances of getting sick.

    Having a freshly changed air filter can also have a big impact on the monthly bills. When the air filter is dirty it prevents smooth flowing air in the HVAC system. When there isn’t smooth airflow, the system has to work harder and takes more energy, which can result in an increase in gas and electric bills. In order to keep energy costs for a home down be sure to change the air filter every couple months.

  • Duct Cleaning

    When people think about getting their ducts cleaned, they first need to ask themselves what made them think they need to do it in the first place. Something subconsciously reminded you, a smell, a sneeze or someone else noticed.

    A temporary solution would be to have someone come to your home and clean your ducts. We have heard of this improving the air quality in customers’ homes.

    During the hot and cold seasons your air conditioning system circulates the air in your home 5 to 6 times a day. When circulating, the air can carry dust and debris from everyday life. Your air filter will catch most of the contaminants but neglect and bad duct installation can lead to a buildup of debris that can negatively affect the function of your AC system.

    Duct cleaning is controversial. Some people believe that it truly helped improve the air quality in their home and they think it was worth every penny. Others think that it is ineffective because your AC system does not blow air fast enough to circulate settled dust throughout the home.

    Can Dirty Air Conditioning Ducts Be Bad for Your Health?

    The EPA says that having your ducts cleaned has been proven to prevent health problems. There is no evidence that suggests dirty ducts increase dust levels inside homes. Some people have allergies and are more sensitive to dust and pet dander than other people.

    Check It Out Yourself

    All you have to do is remove registers and use either your cell phone or small camera, reach into the duct and snap a couple pictures. If it shows that there is a buildup of dust where you can reach, you can use a vacuum cleaner to get as much dust as you can.

    If you see a lot of dust further than you can reach, you may need to get your ducts professionally cleaned. You should clean your ducts after remodeling projects or when buying a new home.

    Ducts Can Be Cleaned By:

    • Hand held vacuum: A brush attached to a large portable vacuum filter is used to clean ducts
    • Mechanical brush: a rotating brush is inserted into the ducts, the vacuum is attached to a truck sucks all the dust and debris
    • Air sweep: truck mounted vacuum carries away dust and debris inside the duct system by a compressed air hose

    The most important thing to figure out is how it got dirty originally. You can solve problems by identifying them first.

     

  • HVAC Systems in New Homes are Disappointing Homeowners

    For potential new home owners, one of the first things you take into consideration is the plumbing, cabinets, floor and counter tops. The HVAC system ends up being the most unsatisfying feature of the new home.

    There are 9 important things you should remember when you get your HVAC system installed. These will help avoid having your AC company come back out to your home.

    1. Make sure the design and ductwork are correct. If they aren’t balanced or sized correctly your home may not cool or heat properly. Externally insulated ducts that are round are the most efficient type of ductwork.
    2. Be sure the size of your HVAC unit is correct. The size of your HVAC system depends on the size of your home as well as how many windows , how much shade and how much insulation your home has. How much air leaks in and out of your home is also taken into consideration.
    3. Placement of your outdoor unit. The worst place to put the unit outside is by a bedroom window, which could be bothersome to you and your family. Also, make sure it is somewhere where it can’t be easily damaged.
    4. Balance dampers in ductwork. The worst place to adjust the air coming into the room is at the diffuser grill. Balance dampers should be installed away from the diffusers and should also be balanced by a qualified tech.
    5. Refrigerant. Federal Law states that R-22 should be cut out by 2015. I recommend systems that use the eco friendly R-140A.
    6. Location of the Air Filter. They should be located where they can be easily accessed. Filters should be changed every couple of months so it should be located easily.
    7. Return Air. Air that enters a room must be equal to the amount of air that leaves the room. Otherwise there is no space for the cool air to occupy. Each room should have a register and return air diffuser.
    8. Condenser Coil. Single metal coils last longer and are more efficient, for example aluminum or copper coils. This is very important for corrosive environments.
    9. Efficiency. The minimum efficiency for air conditioning systems is 13-SEER, this has been in effect since 2006. The higher the SEER, the lower the energy use.
