When I was in grade school, our class had this wonderful teacher that used to be a vocal coach as well as a 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 lessons she ever taught us is still with me today, and it’s pretty simple to follow: Anything can be memorized with a melody! Sure, it’s kind of embarrassing at first, but it’s not so embarrassing when you’re constantly getting the best grades in class. To this day, I use that trick for everything, even when I’m just trying to remember to take care of a chore. 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 six months without a visit from the HVAC repair technician and it was due time for a visit. We were trying to cut costs on our budget that month due to some unexpected bills, so I figured I’d learn how to inspect HVAC systems and make minor repairs as needed. Using my old teachers’ trick, I was able to learn how to open the outdoor air condenser unit and inspect it for damages and leaks. I also learned to open up the firebox in our home’s furnace, and check the burners to make sure they were clean. Finally, the most important piece 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 even years. It’s important to make sure that air filter is changed out monthly!
