Atlanta Air Conditioning Repair: My Air Conditioner Won’t Turn On

Monday, April 29th, 2013

There are numerous reasons why an air conditioner won’t turn on. With professional installation and maintenance, your AC should run well for years, but there may come a time when it’s endured sufficient wear and tear to warrant professional repair. For Atlanta air conditioning repair, call the excellent technicians at Cool Air Mechanical today!

Let’s take a look at why your AC won’t turn on.

  • Thermostat: First, check your thermostat to make sure that it seems to be operating correctly, and that it is calling for cool air. This sounds obvious, but someone in your household may have accidentally changed the settings. If that doesn’t help, your thermostat may have a connectivity problem. If it’s wired, then it could mean a faulty wiring somewhere between the thermostat device and the AC unit itself; if it’s wireless, then the signal may be getting blocked by some material. You may need a new thermostat.
  • Electrical problem: As you well know, your AC needs electricity to operate, so if you’re AC is not turning on, it’s likely due to an electrical malfunction of some type. First, check that you haven’t blown a fuse or tripped a circuit breaker. If that doesn’t help, then there are numerous possible reasons. You may have a bad capacitor, or you may have a damaged wire in the electrical supply line. If you hear buzzing, then that might be a sign that you have a dangerous electrical arcing issue.
  • Other considerations: Your AC may have just called it quits. The compressor motor may have burned out, or there may be another serious problem with the mechanical system. Make sure you have your AC regularly inspected so that you can pre-emptively take action before breakdowns occur and you’re left with a hot home in the middle of the Atlanta summer.

Atlanta Air Conditioning Question: Why is Water Leaking from My AC?

Monday, April 22nd, 2013

With all the use that your air conditioner gets in Atlanta, it’s no wonder that it requires repair at some point. Even with professional installation and routine maintenance, your AC system—be it central air, heat pump, or ductless mini split—may be in need of minor repair, such as water leaking from your indoor air handler.  In this post, we’d like to address this problem in more detail so that you know what’s going on with your AC. For more information, or to schedule a repair for your air conditioning in Atlanta, call Cool Air Mechanical today!

The water leaking from your air conditioner is probably coming from the condensate drain pan, which sits underneath your evaporator coil to collect any water that has condensed on the coils. This pan connects to a drainpipe that leads to your wastewater disposal system. To understand why there is water there in the first place, let’s take a brief look at your refrigerant cycle.

The refrigerant passes through three major stages in the cooling process. The compressor located in the outdoor unit accepts the gas refrigerant from the evaporator coil and heats it up to a high-pressure and high-temperature gas. This gas circulates through the condenser coil and dissipates its heat into the outside air. Then, the now condensed and cool refrigerant moves to the evaporator where it cools air that is then circulated through your home. During this stage, the water in the air on condenses on the coils, which drips into the pan.

There are a number of problems that can occur with your condensate drain pan. If the drainpipe is clogged with debris, it can cause your pan to overflow into the air handler and onto the floor. Alternatively, if your coil freezes over and then defrosts, it can quickly overwhelm the drain pan.

Atlanta, GA Air Conditioning Question: Why Is My Air Conditioning System Not Dehumidifying?

Monday, April 15th, 2013

Air conditioning is necessary in Atlanta, GA, and homeowners throughout the area are making sure that their cooling systems are ready to go for the entire summer. As you start your AC back up after a season of non-use, you may find that it’s in need of repair or it needs a service tune-up. One common problem that we often hear about is when AC systems are not dehumidifying properly. As you probably know already, your air conditioner dehumidifies the air as part of its normal operation. When it’s not, then it probably indicates some kind of operational problem. For more information, or to schedule air conditioning repair in Atlanta, GA, call Cool Air Mechanical today!

Here are some possible causes of an AC system that is not dehumidifying:

  • Inadequate refrigerant charge: The “charge” is the level of refrigerant that circulates through your compressor pump, evaporator, and condenser. It’s imperative that your system have the correct amount of refrigerant at all times. If you have low refrigerant charge, then it’s possible that your AC system will not dehumidify the air.
  • Oversized system: If your AC does not dehumidify the air and also frequently turns on and off, then it is probably too large for your home. What happens is that the high-powered system cools the air at such a fast rate that the air does not spend enough time moving over the evaporator coil to be dehumidified. After your thermostat shuts off the cooling because your home has reached the desired temperature, there is still a lot of humidity in the air.
  • Dirt and debris in the system: One of the best ways to prevent damage to your system is to ensure that all of its components are clean and clear of any dirt and debris. If your coils are covered in dust, then you cannot expect it to work efficiently, and one of the potential outcomes is a lack of dehumidification.

If your AC system is not dehumidifying properly, then it requires professional attention. Make sure your AC performs well and efficiently this cooling season by scheduling Atlanta, GA air conditioning repair and maintenance with Cool Air Mechanical. Call today!

Atlanta Air Conditioning Tip: How Do High Velocity AC Systems Work?

Monday, April 8th, 2013

High velocity AC systems are a great alternative to conventional ductwork. They are highly efficient, quiet, and can be retrofitted into nearly any home, no matter how old or compact. While many have already jumped on the high velocity bandwagon, it’s important to understand how these systems work in order to understand how they might work for you. High velocity systems are particularly well suited to historical, open floor plan, and post and beam homes, or for structures where conventional ductwork would significantly damage the existing infrastructure. That said, they can installed in nearly any structure and are quickly becoming a new standard for home construction. For more information about high velocity AC systems, or to schedule a consultation, call the Atlanta air conditioning experts at Cool Air Mechanical today!

So, how do they work? Let’s break it down according to component:

  • Air handler: One of the unique features of a high velocity air conditioning system is the placement of the air handler, which is often in the attic, but can also be installed in the basement, garage, or even in a closet. They are rectangular units that sit upright or supine. They connect to a conventional outdoor condenser/compressor unit or heat pump. They are equipped with an evaporator coil that removes up to 30% more humidity than an average indoor unit does.
  • Ductwork: The key to high velocity air conditioning ductwork is flexibility. The diametrically larger insulated ductwork immediately surrounding the air handler connects to small, insulated flexible tubing, typically only 2” in diameter. These are sent throughout your house. Because they are about one-third of the size of conventional ducts, they can maneuver into areas previously thought inaccessible.
  • Outlets: The days of large, bulky, metallic duct registers are over. The sleek and compact circular outlets of high velocity air conditioning systems are not only less obtrusive to the eye and ear, but they also provide greater efficiency of cool air dispersion. The gentle circulation of cool air throughout your home allows for an incredibly even and consistent cooling experience.

If you think a high velocity air conditioning system might be a good fit for your home, talk to your AC professional. For Atlanta air conditioning installation, call Cool Air Mechanical today!

Why Your Atlanta, GA Air Conditioning Installation is Not a DIY Job

Monday, April 1st, 2013

Purchasing a new air conditioning system for installation in your home is a great way to ensure that you’ll make it through the long, hot summer comfortably. When it comes to the installation of that new air conditioning system, though, you must make sure that you contact a qualified professional to handle the service. Even the most dependable products from the most trusted manufacturers in the business will fail to keep your home comfortable if not properly installed. Call the Atlanta, GA air conditioning installation technicians at Cool Air Mechanical to have your new AC installed right.

One main reason that your air conditioning installation is not a DIY job is simply due to the complexity of the equipment. A whole-house cooling system is a lot more complicated than a window unit, and the installation will have great bearing on the efficiency and effectiveness with which the system operates. If the indoor and outdoor units are not properly installed, along with the ductwork and controls, you will not be able to keep your home comfortable reliably.

Even prior to the installation itself you will find that the assistance of a qualified professional is necessary. The sizing of your system, for example, is very important. If your new AC is not properly sized for your home then it will fail to cool your home with a quality performance. If it is too small it will not be able to reach desired temperatures, and the strain put on it can lead to damage. If it is too large it will short cycle frequently, incurring unnecessary wear and tear.

Plus, some warranties may be voided if you attempt to handle the installation or service of your air conditioning system on your own. Not to mention the fact that there are safety concerns to consider, as there always are when dealing with electrical connections. Make sure that your AC is installed with the care and expertise that only a qualified professional can provide.
