One time when I was hanging out at my buddy’s home while watching the football game, my buddy went to change her air filter during a single of the commercial breaks.

I thought it was kind of stupid that she was so drastic about getting her air filter changed, but she said she was adamant about keeping her air filter swings on a narrow schedule.

That particular day just happened to be the day when she had to make sure the air filter was changed. I started talking to my buddy about it plus asked him why she couldn’t be a day late or even a week late on the air filter replacement. She came back at me with a question of her own. She asked me how the air quality was in her townhouse. I said it seemed to be just fine. That’s when she said the air quality was better because she changed her air filters properly on time. She also had lower heating and cooling bills because she never had clogged air filters in her Heating plus Air Conditioning system. She said even if I replaced the air filters a week late, that would cause stress on her Heating plus Air Conditioning system so higher utility bills was not the only problem. It was not worth it to damage the Heating plus Air Conditioning system. I undoubtedly never thought that changing the a/c air filter was so serious, although I realized that I had an issue at my home with pretty high utility bills plus I could use better air quality too. I ended up being more adamant about my air filter swings after that. It was funny because my friend started coming over to my townhouse to watch some of the games when she realized that I had improved air quality at my place.
