I never changed my air filters
When I first moved into my apartment I loved how clean my indoor air quality was. Every time you would walk in there it was like taking a breath of fresh air. However, this didn’t last and I noticed that gradually over time the indoor air quality was degrading. I can never figure out why but I knew that it was getting worse and I didn’t want my indoor air quality to continue to be this way. Then one summer came along I noticed that my air conditioning unit had started making some strange noises and so I was going to have a service by a cooling professional. So I contacted the building maintenance and they sent out a heating and AC guy to come and take a look at it. When the heating and air conditioning guy came over to my place he then asked me when what’s the last time that I changed my air filter? I stood there dumbfounded for a second at his question. I hate to admit it but I was confused. I asked him to clarify what he meant and he repeated again if I had to change my air filter recently? That is when I had to confess that I hadn’t changed my air filter at all, and not only had I not changed it but I didn’t know that I was supposed to change my air filter. I could tell that this HVAC technician found the fact that I didn’t know this clearly obvious part of heating and cooling maintenance to be funny. He then showed me how to change the air filter and gave me a new air filter for free. Surprisingly, after the air filter was changed my indoor air quality problems went away. That’s when my brain was finally able to connect the dots between the two issues. Now I change my air filter every 3 months as they recommend.
