Every 2 to 3 months I change the air filters in my beach house. This is something I have been doing ever since I moved to this property. Before that, I was living in an apartment in the city, and it is where I learned about the importance of changing air filters frequently. During that time, I knew that certain matters like the HVAC system were the job of the building handyman. He would go to each apartment with issues such as plumbing, and so much more. After a year of living in my apartment, I started experiencing issues with the heating and cooling. I remember one summer when the apartment was hot and uncomfortable. This went on for some time so I asked the building handyman for assistance. He came to my place and started to look at the air filter. It was filthy and I then understood why air wasn’t flowing into my home. The handyman put in a new air filter, and showed me how it is done. He taught me how to change an air filter, and recommended I do so every 2 to 3 months to avoid such issues in future. I took that lesson to heart and have been doing the same in my new home. I make sure to purchase air filters in bundles so I have them at hand when it’s time to replace the dirty air filters. A friend was at my house the last time I was doing this and he was quite impressed that I know how to change air filters. Most people don’t and they have to pay an HVAC technician to do the work for them.
