What we did
Homes with more than one level often have more than one filter to keep track of, and that was the case at this Danville house. During a scheduled visit in May, we changed the air filters for both the upstairs and the downstairs.
Each floor uses a different size. Upstairs takes a 16x25x1 filter, and downstairs takes a 20x20x1. We replaced both, so the whole house is now starting fresh. Mixing up sizes or forgetting one of the filters is easy to do in a two-level home, and it is one of the reasons we like to handle these changes as part of regular maintenance.
Clean filters help the HVAC system operate efficiently because air can move through them without restriction. They also play a part in better air quality, catching dust before it gets pushed back into the living space. For Kentucky homeowners, whose systems run hard in both summer and winter, staying on top of filters on every floor is a straightforward way to support system performance. If you have a multi-level home and are not sure what sizes you need, we can help you sort that out.
