• Smells Your AC Unit Makes and When You Should Be Concerned

    Most of the time, your air conditioning unit blows air into your home that you probably don’t even notice. It just flows through your house unobtrusively, keeping you comfortable without being noticeable. Sometimes, though, you turn on your air conditioner and an unpleasant odor fills your home. It might smell like dirty gym socks, it might resemble exhaust fumes or the air in your home might suddenly smell like rotten eggs. Should you be concerned? If foul-smelling air comes out of your HVAC unit, is it dangerous?

    • Dirty sock syndrome is no laughing matter. It may sound like a funny thing to call an air conditioning issue, but it is actually a term used in the HVAC industry. What’s more, in some situations it can be dangerous. It happens when a foul, moldy smelling odor comes from your air conditioner, and it’s caused by mold, mildew, and bacteria on the evaporator coil. This is especially common in warm climates, where it’s not unusual for it to be hot enough to run the air conditioner during the day, and cool enough to run the heat at night. Heat mixes with dust and moisture inside the air conditioning unit, causing mold and mildew, which creates that dirty, musty smell. To combat this problem, make sure the drainage pans are empty, replace your air conditioning filter, clean your condenser coils, and clear any blocked drainage lines. If the smell persists, call in a professional. If mold continues to grow inside your HVAC unit, it can cause health risks to you and your family. You can often prevent dirty sock syndrome by using high-quality air conditioning filters and a UV air purifier.

    • Sometimes, your air conditioner may smell like exhaust fumes. Why would that happen, when your air conditioner is not powered by gas? The answer is simple: fluids in the engine and in other parts of your air conditioner can leak out and cause an odor that resembles exhaust fumes. The only thing to do in this situation is to call for professional assistance.
    • A gun powder smell is also something you might find mysterious. This usually indicates an electrical problem, like a fan motor or circuit board that’s shorted out. Keeping your HVAC unit in good repair can prevent this problem, but if you smell something that smells like gun powder, call an HVAC contractor.

    • Like the gun powder smell, a burning smell can mean electrical issues. It could be a mechanical problem with the fan or compressor, it might be a wiring issue, or it may be a failure of an electrical component, but whatever it is, it’s not healthy for you to breathe in burning odors. Sometimes, it may not be serious: if it only happens when you first start it up, it could just be dust burning off of your unit. If the smell persists, though, don’t try to repair it yourself. it’s best left to a professional because fixing a problem with the motor or wiring can lead to injury if you don’t know what you’re doing.

    • A skunk smell usually indicates a gas leak in the system. Methyl mercaptan is a gas that smells like a skunk’s spray, and when it gets into your ductwork it can cause this smell to enter your home. If this happens, evacuate your home immediately, and call your air conditioning repair company, because this is a dangerous gas and requires immediate attention.

    • Rotten egg smell may mean something has died. Often, birds or rodents get into air ducts in the winter, and if they die and begin to decompose it will lead to a horrible odor in your home. If your home smells like rotten eggs, your ducts need to be professionally cleaned. Another source of rotten egg smell is a natural gas leak. In either case, it’s smart to call in a professional HVAC contractor immediately.

    • Mold and mildew have their own distinctive smell. A moldy odor in your home usually means that mildew or fungus have started growing in or near the air conditioning unit. Because mold thrives in moist areas, it makes sense that it would grow in HVAC units that aren’t draining properly. What’s more, dirty filters often five off the scent of mildew. If you smell a moldy smell, change your filter. If the odor persists, call in a professionally trained HVAC technician.

    Of course, bad smells are not the only indication that something is amiss with your air conditioning unit. Various sounds can indicate a problem with your HVAC, as can excess water or other liquids leaking from the system. One way to get ahead of these issues is to have annual maintenance performed on your system, but if you find yourself with an air conditioning system that doesn’t smell, sound, or perform the way it should, it’s time to call in an HVAC professional.

  • 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.

    If you need to find a professional to check your HVAC, or you’re in the market for air duct cleaning, repair, and replacement services in Tampa, St. Petersburg and the surrounding area, please feel free to call Air Rescue at (813) 375-9982.

  • How to Keep Your HVAC Running Efficiently

    Running your HVAC systems efficiently means that they are cooling or heating to the best of their ability while saving as much energy as possible. The best ways to run an efficient HVAC system is with regular heater and air conditioning maintenance in Tampa. This maintenance should include yearly cleanings, changing air filters, and professional inspections by a qualified HVAC company. Continue reading for a closer look at how to run your air conditioner and heater efficiently. regular - hvac - maintenance

    Schedule Routine Maintenance

    One of the easiest ways to run an efficient HVAC system is by scheduling routine maintenance. Both your heating and air conditioning units should be cleaned and inspected, at least once a year, by your qualified HVAC company. Every year that you do not have your entire HVAC system inspected, it can lose up to 5% of its efficiency. The longer that the system goes without inspection, then the harder it will work and your energy bills will steadily rise.

    Change Air Filters

    It is important to change the air filters for your air conditioner and your furnace. These filters prevent dust, dirt, and contaminants from invading your home, which keeps your air healthy and comfortable. Change your filters every three to four months at minimum; you may wish to change them every month during the summer and winter. During these seasons, you are likely using your heater and air conditioner more often, which will make the filters dirtier. By replacing filters regularly, you can reduce the strain on your HVAC units, which will help them to run more efficiently.

    Use a Smart Thermostat

    Smart thermostats are programmed to analyze your daily actions and change the temperature conditions as needed. For example, if you are gone every day during certain times of the day, then a smart thermostat will program the HVAC units to reflect a more efficient temperature. There is little point to cool your home when you are not at home, so a smart thermostat will raise the temperature a few degrees. This will reduce daily strain on your air conditioner, and it will lower your energy bills.

  • Understanding Mini Split AC Systems

    For homes or additions that lack ductwork, split AC systems offer an excellent solution. If you’re considering mini split air conditioning installation in Tampa, then watch this video to learn more about this type of air conditioner .

    A mini split air conditioner is a cooling appliance that does not require any ductwork. Many individuals choose this type of unit instead of a window air conditioner due to their small size, versatile installation options, and ability to run quietly.

    These air conditioners have one section that is mounted to a wall inside of the home, and a second portion, containing the compressor, that is outdoors. If your home does not already have ductwork installed, a mini split system can allow you to enjoy cool indoor temperatures without adding a lot of holes, ducts, and insulation to your home.

  • Proper Air Conditioner Maintenance

    Professional air conditioning maintenance in Tampa should be done at least once a year. This means a licensed and experienced heating and cooling company will come out to clean and inspect your air conditioner.

    As you watch the video, you may be surprised to find out that every year your air conditioner goes without a professional tune-up, it can lose up to 5% of its efficiency. This means you are losing money every year you go without air conditioning service. The best ways to service and maintain your air conditioner are with professional inspections and cleanings. You should also change your air filters every time they are dirty. Depending on your usage, you may need to change the filters every month. This will keep your indoor air quality high and clean while your air conditioner is running.

  • The Anatomy of Your HVAC System

    The summer season is about to arrive, and now is the time to contact your HVAC company in Tampa to perform air conditioner repair for your home. With proper air conditioning repair from a highly rated company offering services for your HVAC system , you can ensure that your air conditioning is in proper working condition during the hottest months of the year. By learning about the components of your heating and air system, you will have a better idea of what to look for when something goes wrong. Read on for a closer look at what you need to know about the anatomy of your HVAC system.

    Air-Conditioning-Components

    Air Conditioning Components

    Whether you have a ductless air conditioner or a central unit, your air conditioner will be made up of a condenser and an evaporator. The evaporator is used to generate cool air as refrigerant flows through the lines. By contrast, your air conditioner’s condenser unit is designed to eliminate any excess condensation that is created during the cooling process.

    Heat Pumps

    If you use your HVAC system for both heating and cooling, you may have a heat pump in your home. The anatomy of a heat pump is similar to that of an air conditioning unit. As air is pumped into your home, it travels through the heat pump, where is it heated up gradually. With the use of a heat pump, you will be able to cool your home safely, effectively, and in an environmentally friendly manner.

    Furnaces

    For those homes that are not equipped with heat pumps, a furnace is typically an integral part of the HVAC system. Unlike a heat pump, which creates hot air as it flows through the ductwork of your home, a furnace is a specially designed appliance that creates heat through a combustion system. In order to ensure that your home remains safe when your heat pump is turned on, your furnace will also be equipped with a vent that transports combustion gases safely to the exterior of your house.

  • The Essentials of Shopping for a New Air Conditioner

    By replacing your home’s old air conditioning unit, you can cut your energy costs and cool your home more efficiently than ever before. Today’s air conditioners are designed to cool homes quickly without using as much energy as older models, which is why it’s a great idea to upgrade your current AC unit. Air Rescue specializes in helping homeowners with AC installations in Tampa and can install one for you right away.

    Before you start shopping for a new air conditioning unit, you should find out exactly what size AC unit you need. Rather than just replacing your current AC unit with one that’s the same size, have a heating and air conditioning company like us evaluate your home and tell you what size AC unit would serve you best. You should also compare the seasonal energy efficiency ratio, or SEER, of different air conditioners and find one that’s efficient enough for your home. You should even consider repairing your home’s ductwork and installing insulation so that your entire HVAC system works better with your new AC unit. When you work with Air Rescue, we will make sure you love your new air conditioning system once it has been installed.

  • How to Buy an Air Conditioner

    An air conditioner can keep your house cool and your utility bills low, but there are things to consider before you order an AC installation in Tampa . Choose a unit with the following features: an air filter, high energy efficiency ratio (EER), measuring tape, adequate British thermal units (BTUs), oscillating louvers, built-in timers, a digital display, touch-pad controls, a remote control, and a warranty.

    Determine what type of air conditioner would work best in your living space: a wall, window, portable, or room unit. Select a unit with an EER of 13 or more. Make sure the AC has an air filter; this will reduce allergens. Measure the square footage of your room to determine the needed BTUs. Once your AC installation is complete, perform routine AC maintenance and contact an AC repair company if any problems occur.

  • How to Make Your Air Conditioner More Efficient

    According to the U.S. Department of Energy, 56 percent of your home’s energy bill goes towards heating and cooling your home. In other words, if you want to reduce your monthly energy costs, start by making your air conditioner more energy efficient. In addition to annual AC inspections in Tampa , here are some other ways to ensure your AC runs as efficiently as possible.

    Change the Air Filter
    A clogged air filter forces your air conditioner to work harder to pull air through the system, which requires more energy. To maintain your air conditioner’s efficiency, check the air filter at least once a month and change or clean as necessary. Changing the air filter regularly will not only increase energy efficiency but will also increase the lifespan of your air conditioner.

    A/C Inspection Tampa

    Seal Leaky Air Ducts
    Leaky air ducts are one of the leading causes of high energy bills. As cool air seeps out of leaks in your ducts before it gets to the living areas of your home, your air conditioner has to work longer and harder to cool your home—which means more energy and higher bills.

    Schedule a Tune-Up
    Call an air conditioner repair mechanic to inspect and tune your AC unit at least once a year. It’s best to schedule a tune-up the season before you need your central air system on a regular basis. Your Tampa AC maintenance mechanic will check over the entire system to ensure that all parts are in good working order, which will greatly improve energy efficiency.

    Buy a New Model
    If your air conditioner is more than 12 years old, start thinking about buying a new, energy-efficient model. Energy Star reports that newer models can reduce the amount of energy you use to cool your home by up to 30 percent.
