I never honestly thought I would acquire such an extensive knowledge on Heating plus A/C systems. However, when I ended up purchasing my first home, I realized that I had a lot of reading to do. After about multiple weeks in the brand new house, I realized that it was taking the cooling system much longer to cool the home overall than it should have. It would take nearly an hour before my home started to reach the temperature on the thermostat. After a little research, I found a couple of potential issues. This first thing I did was check my system’s air filter. I hadn’t replaced it since moving in, plus I figured that was the source of the problem in general. When I pulled it out, found that it was filthy. After replacing it with a brand new filter, I actually thought that the concern would resolve. After a few afternoons, it still wasn’t cooling well. I decided to take a step and call the Heating plus A/C contractor for some professional advice. They sent a certified Heating plus A/C serviceman to my home for an inspection. He discovered that the air conditioner’s air handler had frozen up. He told me that this really happened because I waited so long to go ahead and replace the air filter. As the filter filled with dust plus dirt, the air flow began to decrease within my system, so my air handler froze up. He did some cleaning plus other light touch ups on the system before leaving my Heating plus A/C system as good as new; Now I think that it is important to perform routine repair plus cleanings on a heating plus cooling system. It’s better to have routine repairs made than pay for extensive repairs in one fell swoop.
