"I called, not knowing what was wrong with my air conditioning. They actually gave me a few possibilities, over the phone, one of which turned out to be the Culprit. No charge for the advice, they could have easily rip me off. But didn't. They won't give u the run around, and tell you somethings wrong when it's actually not."

"I’ve used this company twice. My husband has a medical condition that is affected by heat. The first time the air conditioner wasn’t working they made every effort to assess the problem immediately when I explained the medical condition. At the time they corrected the problem I was advised the system was probably 20 years old and we may have to consider a new system soon. The second time I contacted Comfortable Carla’s was about 4-6 weeks later when the system wasn’t working again. This lead to a system replacement. I was provided with different options, my questions were answered and the installation was completed as quickly as possible, especially in view of my husband’s medical issue. The staff was was professional, efficient and kept me apprised all throughout the process. I highly recommend this company."

"Phillip was friendly and responsive from the beginning of the project all the way to the end. He provided a very affordable bid and as soon as I confirmed the proposal he went ahead and started the work. Constantly keeping me informed of the progress and it felt that he had my interest in mind at all times. I would absolutely recommend him to my friends and will be sure to call him the next time I need HVAC support."

Air Conditioning questions, answered by experts

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

You should clean your air conditioner at least once per year, but you may need to clean your whole HVAC system (including the air ducts) more often. According to the National Air Duct Cleaners Association, you may need to clean them more frequently depending on factors like whether you smoke, have pets, or have allergies.

A new air conditioner capacitor will cost less than replacing the entire air conditioner system. While a capacitor itself will cost between $8 and $25, paying a professional to replace an AC capacitor will cost $180 on average. It’s not safe to replace an air conditioner capacitor on your own. 

Yes, it’s normal for an AC to drip water. In fact, it’s part of the dehumidifying process that takes place inside your AC unit as the condensation trickles down into the drain pan. However, it isn’t normal for your AC to sound like it’s running water or have large puddles around it. If that happens, you can try the solutions listed above or call an AC repair pro.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.
