I suppose I take air conditioner for granted although I depend on it to fall asleep because the cool air has scientifically been proven to help people sleep better, and there’s something nice about turning on the air conditioner & covering up in blankets for a deep, deep sleep. Well, when my a/c stopped working, I realized how important my a/c entirely is to my wellbeing, and i called a bunch of Heating, Ventilation & A/C companies however they could not come out for at least 4 nights. I did not want to spend my currency for emergency Heating, Ventilation & A/C services so I just had to wait it out. I had a bunch of window fans however they entirely did not do much. When the Heating, Ventilation & A/C specialist finally came out for my A/C repair I found out what the problem was: I had not been changing the air filters nearly enough, but besides that, I was using cheap air filters. The company told me that I need to be using high quality air filters in order to protect my Heating, Ventilation & A/C system. The high quality air filters keep dirt from entering my Heating, Ventilation & A/C system & causing harm. It turned out that I also needed to have my HVAC ducts clean so I had them do that as well. I’m excited that my a/c is working again however I’m not too excited about the bill. But, with the better air filters, & the clean HVAC duct, the air quality in my condo has never been better.
