• 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.

  • 3 Reasons to Consider Replacing Your Furnace

    If you are concerned that your heating system may not be ready for the upcoming winter season, now may be the time to hire an HVAC company to replace your furnace. Without a properly functioning furnace, your HVAC system will not be able to comfortably heat your indoor spaces. By hiring a company that offers HVAC services and furnace repair in Tampa to take a look at your heating unit, you will have a better idea of whether your furnace is in need of replacement. To help you decide whether your home is ready for an HVAC upgrade, here is a look at three reasons to consider replacing your furnace. furnace - maintenance

    Decreased Efficiency

    One of the top reasons to consider furnace replacement is when your unit is starting to show signs of poor efficiency. Some of the common symptoms of poor furnace efficiency include lack of heat coming out of your air vents, high energy bills, or excess energy use. If you are not satisfied with the efficiency of your current furnace, now may be the time to schedule a replacement.

    Poor Air Quality

    Your home’s indoor air quality has a direct impact on the health and wellbeing of your family members. When your furnace is ready to be replaced, you may start to notice that your indoor air is dirty or filled with dust and debris. As your furnace ages, it may be less capable of filtering out contaminants from your indoor air. A brand new furnace will ensure that your indoor air is clean and healthy to breathe.

    Old Age

    A furnace has a typical lifespan of about 10 to 15 years. To determine whether your household is ready for a furnace replacement, you will want to check on the age of your current furnace unit. In the event that you discover that your furnace is a decade old or more, you will want to schedule a replacement service right away.

  • Seasonal HVAC Maintenance 101

    As winter nears, many homeowners start turning their attention to heating and air conditioning maintenance in Tampa. An effective and efficient HVAC system plays a critical role in keeping your home comfortable once cold weather hits, meaning that seasonal tune-ups are a must. The following steps should be completed before it gets too cold to help ensure that your HVAC system is ready for winter. ac - repair

    Change the Filters

    Cleaning or switching out the filters is one of the most important things that you can do to help keep your heating and air conditioning working well and efficiently. When the filters become too clogged with debris, this forces the system to work harder to heat and cool your home, a problem which can shorten its lifespan and raise your energy bills. Additionally, the filter is what helps keep your indoor air clean, so changing it every 1 to 3 months can help maintain your indoor air quality.

    Inspect the Unit

    While the majority of HVAC maintenance should be handled by professionals, performing an occasional visual inspection is a great way for you to catch any warning signs of a potential problem. Start by trimming back any overgrown foliage and removing any debris that may have accumulated around the external unit. If you notice water or any or leaks, dirty condenser or evaporator coils, or frozen coils, contact a heating and air conditioning technician about a maintenance visit. Performing these checks and arranging maintenance visits as needed can help prevent small issues from turning into larger and more expensive ones.

    Schedule HVAC Maintenance

    While you should always contact an HVAC repair company when the system isn’t functioning well, being proactive and scheduling preventive maintenance is a great way to extend the lifespan of your heating and air conditioning unit and to keep the system running smoothly year-round. HVAC technicians are busiest in summer and winter, so spring and autumn are ideal seasons in which to have your HVAC unit tuned up before extreme temperatures arrive.

  • When to Replace Your Ducts

    Air ducts connect your HVAC system to each room in your house. When they are first installed, your air ducts will transport air effectively and efficiently. Over time, however, the ductwork that is connected to your HVAC system may become clogged, leaky, or otherwise compromised. A company that offers air conditioner repair in Tampa will be able to help you boost the performance of your heating and cooling system with duct cleaning or replacement services . To help you decide whether it is time to call in the professionals, here is a look at some of the signs that it is time to replace your ducts. air - ducts

    Your Ductwork Is Getting Old

    To determine whether your ducts are eligible for replacement, you may want to look at their age. A newly installed duct system will last for up to 15 years before it needs to be replaced. When you have been relying on the same ducts for more than a decade, you will be ready to start planning a replacement with your HVAC contractor.

    Your HVAC System Is Losing Efficiency

    The efficiency of your HVAC system is directly impacted by the overall condition and quality of your air ducts. When you find that your HVAC system is consuming more energy than usual, it may be time to start thinking about an air duct replacement procedure. Brand new air ducts will be able to efficiently deliver climate controlled air to each room in your home. With brand new air ducts, you can improve the overall efficiency of your system.

    Your Ducts Fail a Blower Test

    Your HVAC technician will be able to examine the performance of your air ducts through a procedure that is called a blower test. During the blower test, your ductwork will be hooked up to a special testing device. As air travels through your ducts, the testing device will measure how much air leaks out of the system. In the event that your ducts fail the blower test, you will need to set up a replacement.

  • Why You Should Consider an HVAC Tune-Up

    Even if it doesn’t seem like there’s anything wrong with your HVAC system, there are probably parts of it that aren’t running as efficiently as they should. By having an HVAC tune-up done, you can improve the efficiency of your HVAC system, cut down on your energy costs, and prevent major problems in the future.

  • Understanding the Essentials of Furnace and HVAC Maintenance

    If you want to keep your home comfortable and your energy bills affordable, it is important to maintain your heating and air conditioning units. This can also extend your appliances’ working lives and reduce the need for HVAC repair in Sarasota. Be sure to change the air filters on your heating and cooling systems regularly, and check on your units on a seasonal or annual basis. It often helps to enlist the services of a professional HVAC team for help. Read on for help in understanding the essentials of furnace and HVAC maintenance. Maintenance

    Changing Air Filters

    Air filters are the unsung heroes of dryers, furnaces, and many other HVAC appliances. When they work properly, you don’t notice them at all; when they begin to clog up, however, you may run into problems. Air filters are designed to keep dust, dirt, and other debris out of your HVAC units and out of your indoor air. As time goes on, more and more debris accumulates on these filters until they become saturated. A saturated air filter can impede your indoor air quality as well as the efficiency of the appliance itself, so remember to change your filters on a regular basis.

    Inspecting Systems

    Whether you know nothing about your HVAC systems or you are a professional yourself, it is important to check on your units routinely . Regularly inspecting your furnace, air conditioner, or other HVAC unit can help you catch on to problems while they are in their early stages; this gives you the chance to call for help before the problems get any worse. Make sure you clear out any twigs, branches, or other interference from your outdoor air conditioning unit, and test electrical connections before restarting appliances that have been out of use.

    Scheduling HVAC Services

    HVAC maintenance can be a handful in some cases. If you feel that you don’t have the time or know-how to inspect your HVAC systems on your own, do not hesitate to hire a professional. Many companies will regularly stop by to check on your HVAC units according to a predetermined schedule.

  • Choosing a New HVAC System

    HVAC repairs in Tampa can become tiresome and quite costly after a while, especially if your HVAC system is older and on its last legs. When you’re ready to purchase a new heating and cooling system, choose one of the many models on the market today that bares the ENERGY STAR logo. Not only are these newer air conditioners and furnaces more energy efficient, they can also save you a lot of money on your monthly utility bills when compared to standard models.
