Have you ever done something so stupid you just wanted to kick yourself for it? That was me recently! To put it plain and simple, I had went to replace the air filter of our central heating and air conditioner, and I literally forgot to put the air filter in! My central heating and air conditioner ended up running for almost 2 afternoons separate from an air filter in it! It wasn’t until I started hearing this unquestionably different noise coming from the air vents, and noticing that the air was a bit too powerful, that I knew something was seriously wrong anywhere, but that was when i remembered how tired I was when I did it, and at that point seen the air filter I had set aside to put in! It was sitting in the corner of the hallway where I had left it! I instantly grabbed that air filter, and ran down the stairs to get to the venue to change the air filter! I turned off the central heating and air conditioner before I put in the air filter, and left it off for a little while as I wanted to supply it a rest, then right before I turned the temperature control back on about 30 minutes later, I was hoping and praying that I did not destruction our HVAC unit! The last thing I needed at this point was some kind of high HVAC repair bill! I do not have a heating and cooling repair plan with our local HVAC supplier, so the cost would not be too cheap! Lucky for me, nothing was broken.
