In my experience, there is no short answer to that question. The short list of variables that come into play might be things such as: Do I have animals in the house or in the yard? Do I have cottonwood trees in my neighborhood? Is my dryer vent near my air conditioner? Do I live on a gravel road? No two homes are really the same when it comes to maintaining a system, but here are a few tips that you can follow to ensure that your system performs well this summer.
First, I advise my customers to check their filters every 30 days. Some of you may have a thermostat that tells you to change your filter in a set amount of time. Both are good places to start. However, I’ve seen a lot of people throw away perfectly clean filters, and I’ve seen a lot of filters that have well outlived their lifespan. So make it a point to put it on your schedule to just check your filters on the first day of the month. If they need to be replaced, then replace them.
