Decatur, GA Air Conditioning Repair Needs: My Fan is Too Loud

Wednesday, June 26th, 2013

The extreme heat that can come along during a summer in Georgia necessitates a reliable, efficient performance from your air conditioning system. If you have any reason at all to believe that there is a problem with your air conditioning system, it is always best to address that problem as soon as possible. The longer you wait to do so, the greater the risk of serious damage to your air conditioning system. There are a lot of different components that comprise your AC, and any issues with even one of these components can lead to serious operational trouble if given the chance. Call the Decatur, GA air conditioning repair technicians at Cool Air Mechanical with any concerns you may have, such as a fan that seems to be operating too loudly.

There are a few ways in which your fan may exhibit signs of duress. One of them is with a loud humming sound. If your exterior fan is making a loud hum and does not seem to be starting up, you probably have a problem with your capacitor. The start capacitor in your AC gives your system a torque boost when starting up. A faulty capacitor may result in a fan struggling to get going.

A less technical, more mechanical issue may simply be that some component of the fan has slipped, been damaged or bent. If a fan blade is bent it may scraped against the interior of the unit casing. A slipped fan belt can result in a sustained whine until it finally breaks or causes the fan itself to break down. Improper lubrication is another major cause of a loud operation from your fan, and certainly one of the most desirable as it is an inexpensive fix. Whatever the cause of your particular problem, one thing is certain: it is always best to ensure that your AC repair needs are met as soon as possible.

Atlanta, GA Air Conditioning Repair: Signs of a Bad Capacitor

Tuesday, June 18th, 2013

Are you frustrated by unreliable cooling? Does it seem like your AC only starts up when it wants to? If you’re not getting what you want from your AC this summer, then it’s time to take action. With professional installation and routine maintenance, your AC should run well for years after it is first installed, but there will come a time when it develops a problem in need of professional service. One area of your AC that can develop a problem is the capacitor, which functions like a start-up battery for the operation of your air conditioning components. There are some signs of a bad capacitor worth looking out for. In today’s post, we’d like to examine a few briefly. Call Cool Air Mechanical today for exceptional Atlanta, GA air conditioning repair services.

  • AC fails to start up: This is probably the most obvious sign that you should have your capacitor checked, but a failure to start can be caused by various other problems as well. It’s important to have your AC checked by a professional to determine the cause of the issue.
  • Intermittent failure: If your AC fails to consistently start-up when you call for cooling, then it could be a sign that your capacitor is beginning to fail.
  • Tripped circuit breaker: As you well know, your AC operates on electricity. It is wired into your service panel, and if you find that your circuit breaker trips frequently, then your capacitor might be at fault. This results from the motor attempting to draw a higher voltage than normal because your capacitor is not providing the energy boost.
  • Humming sound: If your compressor motor hums during start-up or overheats, then it could be drawing more electrical energy than normal because of a capacitor issue.

Your capacitor is vital component of your air conditioning system, and you simply cannot expect cool air without it. If yours is no longer operating properly, then call the Atlanta, GA air conditioning repair service experts at Cool Air Mechanical today.

Why Is There a Bad Smell Coming from My AC? An Atlanta Air Conditioning FAQ

Tuesday, June 11th, 2013

Having good air conditioning in Atlanta is a huge priority for every homeowner. But with all the use that your AC gets during the summer there are a few problems that can start to arise. A very common issue that we get called for is a strange smell coming from the AC. We wanted to let our customers know what might be causing this problem.

One of the main cause of a bad smell coming from your air conditioning system could be mildew in the condensate pan. As your air conditioning system cools your home condensation forms on the evaporator coils inside the system. This is similar to what happens when you take a cold glass outside on a hot day. That condensation will normally drip down into a pan and then drain away. But if the drain gets clogged it can allow bacteria and mold to start to grow which could cause an odor to occur.

If there’s a bad smell coming out of the registers in your home when you turn on your air conditioning system this could be caused by mildew or bacteria growing in your ducts. It could also be mold or bacteria grown on the actual evaporator coils themselves.

Call the Atlanta air conditioning experts at Cool Air Mechanical today to talk with one of our friendly specialists today about any AC or duct cleaning services that you need. We’ll work hard to quickly find the source of the odor and eliminate it.

Atlanta Air Conditioning Repair Tip: Why Your AC Blows Warm Air

Tuesday, June 4th, 2013

There’s simply no substitute for the crisp, refreshing cool air that flows out of your air conditioning system. During the high temperatures and dense humidity of the summer, you need to make sure that your AC is ready to work well no matter what the outside temperature is. But one of the problems confronting homeowners occurs when their AC begins to blow warm air. This is probably the last thing you want to have happen. After all, you’re paying to stay cool. That’s what makes professional repair so important. Without the technical expertise and knowledge of an HVAC technician, your AC will simply not get the attention it deserves. Call Cool Air Mechanical today if you need Atlanta air conditioning repair services.

Why does your AC blow warm air? Let’s take a look at a few possible options.

  • Low refrigerant: Refrigerant is the chemical designed to produce radical temperature fluctuations under different pressurized conditions. But in order to absorb and dissipate thermal energy so that you can enjoy cool air, you need the correct amount of refrigerant in your system. During installation, your AC was “charged” with refrigerant, and shouldn’t expend it during operation. But if you have low refrigerant levels, then your AC may not function efficiently, and it may be subject to such problems as warm air. Low refrigerant is typically caused by a leak somewhere in the coils, because of either puncture or corrosion. The leak will need to be repaired before the system can be recharged. 
  • Dirty condenser coils: The condenser coils reside in the outdoor unit with the compressor. They have a single purpose: to dissipate the thermal energy from the indoors. The compressor heats up and pressurizes the gaseous refrigerant as it comes from the evaporator, and then sends it to the condenser. By raising the temperature above even the hottest outdoor air, the compressor allows the condenser coils to let the heat flow into the air by means of an exhaust fan. Obviously, this process cannot work well if there is dirt and other debris caked onto the coils. It impairs the dissipation process, and thus reduces the ability of the other components to do their parts.
