The top 10 most common air conditioning problems. Coming in with an overwhelming first place is a bad capacitor; when the capacitor goes bad, it'll bulge out on the top. Sometimes it's rare, but sometimes the whole top will pop off, and you'll have that dielectric grease all over your electrical section. There are other times when the capacitor looks good. However, it's still dead, and the only way to check that is to use a meter, or you can blindly replace it because that is the most common fix.

Wouldn't it be nice if you knew your air conditioner's cold air was clean and healthy? In addition to your air's output temperature, there are other factors for measuring air quality. We have a suggestion that can ensure your air is clean and safe, but the only way we can help you is for us to come out and evaluate the air quality coming out of your existing air conditioner unit. In addition to regular maintenance, such as changing your filter and cleaning the air conditioning coil, we have rigorous methods to determine your A/C unit's air quality and performance when repairing it.

I want to go over a furnace/heating system and the sequence of operations. Understanding the primary function of the individual components will make it easy to troubleshoot simple problems. Before we take the doors off and go over the inner workings, if your furnace isn't working, the first thing you want to do is look into your sight glass, which will be on the furnace's bottom door. Most of the newer furnaces will have them and if that's blinking some error code, remember what that code is before you take the doors off.
