I had the worst thing happening to my Heating and Air Conditioning plan in the center of last summer. Every now and then, after going for a while the a/c would just entirely turn off. After looking into it, I realized the cooling system circuit breaker was going haywire. The first time it went down was while in a storm, so I figured that weather had hit the truck nearby and caused the breaker to trip. The next time it went on it was on a perfectly clear out. It was a sunny afternoon, so I figured it must be the Heating and Air Conditioning plan itself. The next time it happened I simply flipped it back on, however after that I got to pondering about what was the real issue. I seemed to remember that breakers are often went haywire when a power overload is looked at. I realized there may be something going bad with my Heating and Air Conditioning plan that could be a fire issue if not officially dealt with. The afternoons were not getting any colder, so I called an Heating and Air Conditioning professional out to figure out what in the world was going on with my air conditioner system. It turned out that a dirty air filter was the root source of the problem. The fan belt in my Heating and Air Conditioning plan was having to work extra hours to draw cool air through the gross air filter. It was having to run more and draw on a ton of electricity and thus the cooling system circuit breaker went haywire.
