• Strange Noises Your AC Unit Makes and When You Should Be Concerned

    During the summer, you probably rely on your air conditioner to keep your home cool and comfortable. Most of the time, it hums along in the background, providing you with cool air without giving you much trouble. If it starts making unusual noises, however, it can be very off-putting. How do you know if a noise is normal, or if it’s something that requires professional attention?

    Air conditioners often make some strange sounds. The important thing is to make note of the type of sounds you’re hearing because different noises mean different issues. Do any of the following descriptors seem familiar?

    • Squealing: Typically, if your HVAC unit is making a high-pitched squealing noise, it’s either the belt connecting the motor to the blower or the bearings on the motor of your condenser fan. Newer units don’t usually have a belt, but if your unit is older and you’re hearing the sound both inside and outside your home, the belt is probably the problem. It may need to be replaced, or it may just need lubricant. Even if it’s as simple as a lubricant, it’s not a bad idea to go ahead and replace it, because when the belt breaks, the air conditioner stops blowing. With a newer unit, squealing is probably caused by the condenser fan motor’s bearings. Direct-drive motors don’t use a belt, but bad bearings can cause squealing and grinding from the outdoor unit. When this happens, the motor probably needs to be replaced. Note: if your air conditioner always makes a squealing sound when it first starts up, but the sound stops after a little while, it’s probably not actually a problem.
    • Buzzing: Loud buzzing noises coming from the air conditioner are usually bad news. The issue may be loose parts, missing or broken isolation feet, leaking refrigerant, or a compressor that’s malfunctioning, but whatever it is, it indicates a need for repair. If one part goes bad, it can put stress on the rest of the system, so it’s important to have repairs made as soon as you know something is wrong. Buzzing may mean that the rubber feet at the base of your air conditioner have begun to disintegrate or crack, causing the compressor to become out of balance, which creates the buzzing sound. It may also mean that the refrigerant has begun to leak, which can cause your AC to actually freeze up and stop working. On the other hand, the buzzing may be the result of an electrical problem or a malfunctioning compressor. It could also be due to debris in the unit, either indoors or outdoors, loose parts, copper lines rubbing against something, an air filter in need of changing, or a condenser coil that needs cleaning.
    • Chattering: Whether or not this is serious can’t really be determined just by listening. It could mean that your HVAC is on the way out, and the parts are starting to loosen. On the other hand, it could just mean that twigs or leaves have clogged your system. The first thing to do if you hear a rattling, chattering sound is to check for loose screws in the casing of your unit, then clean the condenser coils and change the air filter.
    • Whacking: This sound is often more annoying than it is serious. It probably means that there’s debris lodged in your motor blades, and it’s time to clean it out before it leads to bigger issues.
    • Clicking: It’s normal to hear clicking at start-up or shutdown of your system, but if the clicking keeps going, it could be a sign of a defective control or a thermostat that’s about to go bad. As with any electrical issue, it’s important to deal with It as soon as possible.
    • Humming: When your air conditioner is humming, you should probably have your unit checked out by a professional. It may not be a serious problem, but it could indicate loose parts that can lead to a more serious issue, or it could indicate electrical problems.
      Clanking or Rattling: This probably means that a part inside your air conditioner is loose, out of balance, or misaligned. Do not ignore this kind of sound, because there’s a significant chance that these out-of-whack parts can lead to bigger problems.
    • Thumping or Banging: When the noise in your air conditioning unit moves beyond rattling and clanking and on to thumping or banging, it means that something serious is amiss. Most likely, a broken part has come loose and is being thrown around your unit. If that’s the case, it must be repaired quickly, before the loose part causes damage to the rest of your system. Thumping and banging can also mean your compressor needs to be replaced.
    • Screaming: If your air conditioner starts screaming, turn it off immediately and call in a professional. A screaming sound can mean a refrigerant leak, which may be harmful to your family’s health, or high pressure inside your compressor, which is an extremely dangerous situation. In fact, your compressor may turn off on its own as a safety measure.

    It’s important to know who to call for repair, and it’s also smart to have annual maintenance, to prevent these repairs from becoming necessary in the first place.

  • 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.

    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.

  • 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.

  • What Frequent AC Cycles Could Mean for Your System

    Are you wondering if you need air conditioner repair in Sarasota because your AC turns on and off too frequently? If so, then read on to learn what frequent AC cycles could mean for your air conditioning system.

    When you have an air conditioning service install a new AC in your home, one of the most important factors is the unit’s size. Air conditioners that are too small for your home are forced to run for longer periods than they are designed to run. On the other hand, a unit that is too large will turn on and off frequently because they can drop the home’s temperature so quickly. While this may sound like a good thing, it can wear out the unit’s parts prematurely and cause your home to feel damp and clammy.

    Other issues that can be related to frequent AC cycles are a malfunctioning unit or thermostat. If you believe that your air conditioner is turning on and off too often, call an HVAC technician today to schedule an inspection.

  • The Science Behind Air Conditioning

    You have heard the low humming sound it makes when it turns on, but you have likely never peered in to see exactly what is going on inside your air conditioner. Understanding how your unit works can help you provide the proper air conditioning maintenance and perform adequate HVAC repair in Tampa. These factors will allow you to enjoy your air conditioner’s long and efficient working life. Keep reading if you are interested in learning a little bit about the science behind air conditioning.

    What Happens Behind the Scenes
    People know air conditioners as the boxes in their yards and windows that keep their homes comfortable throughout the summer. However, not many people recognize the processes of evaporation and condensation that go on inside these HVAC Repair in Tampa boxes, and thus are relatively clueless when it comes to air conditioner repair. Your air conditioner creates cool air using a substance called a refrigerant. This refrigerant evaporates at a low temperature inside metal coils; once the refrigerant evaporates, the coils cool. A fan blows air over these cool coils, and this newly cooled air circulates through your ductwork and into the various rooms of your home. Your unit’s compressor then causes the refrigerant to condensate and turn back into a liquid, which creates heat. Another fan expels this heat to the outside of the unit, and the refrigerant continues the cycle by evaporating again.

    Descriptive Units
    Two important acronyms that describe different aspects of air conditioners are Btu and EER. Btu stands for British thermal units and tells you how much heat is required to heat one pound of water by one degree Fahrenheit. Btu is important when it comes to choosing the right size unit for your home. EER stands for Energy Efficiency Rating and compares a unit’s Btu with its wattage. Higher EER ratings mean more savings.

    The Energy Efficiency Difference
    An energy efficient air conditioner makes the most of the power that it is given. This means that you will save money on your energy bills and reduce your home’s carbon footprint at the same time. These units also tend to last longer.
