A few years ago, I realized that my air conditioner was starting to die. In addition to struggling to pump out cool air, it made a lot of noise. After calling an HVAC professional to look at my system, I realized that a lot of the problems were my fault. My air conditioner coils were clogged with dust and dirt, and the actual motor had developed some pretty serious problems. I felt really dumb about it, but I learned a lot about HVAC that summer. This blog is designed to teach you how to keep your air conditioner and furnace in tip-top condition.
