I think I take air conditioning for granted but I depend on it to fall asleep because the cool air has scientifically been proven to help people sleep better. There’s something nice about turning on the air conditioning and covering up in blankets for a deep, deep sleep. Well, when my air conditioner stopped working, I realized how crucial my air conditioner really is to my wellbeing. I called a bunch of HVAC companies but they could not come out for at least 4 days. I did not want to spend my money for emergency HVAC services so I just had to wait it out. I had a bunch of window fans but they really didn’t do much. When the HVAC specialist finally came out for my AC repair I found out what the problem was: I had not been changing the air filters nearly enough. Besides that, I was using cheap air filters. The technician told me that I need to be using high quality air filters in order to protect my HVAC system. The high quality air filters keep dirt from entering my HVAC system and causing damage. It turned out that I also needed to have my air ducts clean so I had them do that as well. I’m happy that my air conditioner is working again but I’m not too happy about the bill. But, with the better air filters, and the clean ductwork, the air quality in my home has never been better.
