When I was in grade school, we had this awesome teacher that used to be a vocal coach and talented singer. She was sweet as could be, and really knew how to make sure we all had every tool to succeed. One of the best things she ever taught us is still with me today, and it’s pretty simple to follow: Anything can be sang with a melody! To this day, I use that trick for everything, even when I’m just trying to remember to take care of a chore around the house. Once, I made a song in my head all about getting our home’s heating and air conditioning system checked up, as we’d gone several months without a visit from the local and friendly HVAC repair technician and it was due time for a visit. We were trying to cut costs on our budget this month due to some unexpected bills, so I figured I’d learn how to inspect HVAC systems and make minor repairs as really needed. Using my old teachers’ trick, I was able to learn how to open the outdoor air condenser unit and inspect it all the way for damages and leaks. I also learned how to open up the firebox in our home’s furnace, and check the burners to make sure they were very clean. Finally, the most important part of all, I remembered to change the air filter for the heating and air conditioning system! Many of the issues that arise with heating and cooling systems originate with an air filter that hasn’t been replaced in months or sometimes even years. It’s important to make sure that air filter is changed out always!
