What we did
This Stanford home runs two separate HVAC systems, a Goodman downstairs and a Bryant upstairs. In January 2026 we stopped by for a scheduled servicing visit on both.
On the downstairs Goodman system, we replaced the filter with a new 20 x 20. The upstairs Bryant system takes a 16 x 20, so it got a fresh filter of that size. Keeping the two straight matters, because each system is built around its own filter dimensions and a poor fit can let unfiltered air bypass the media entirely.
Homes with equipment from two different manufacturers are more common than people think, especially when systems have been replaced at different times. Each one still relies on the same basic upkeep to keep running well. Fresh filters help the blower move air without extra strain and keep dust from collecting on the coils and other internal parts. In a Kentucky winter, when furnaces run long cycles day after day, that kind of proactive maintenance helps both systems operate efficiently and effectively. If you have more than one system in your home, we can keep track of the sizes and set up regular visits so you do not have to.
