What we did
Winter is when a furnace earns its keep, and in January we were back at a Danville home for scheduled HVAC maintenance. Our technician Max handled the visit.
As part of the maintenance, Max replaced the 20x20x1 filter. It is a routine step, but it is an important one. The filter protects the system by catching dust and debris before they reach the blower and other components, and it plays a part in keeping the air inside the home cleaner. A clogged filter forces the system to work harder to move air, while a clean one lets it run the way it is supposed to.
In central Kentucky, January often brings the coldest stretch of the year, and the heating system may run for hours at a time. That makes the middle of winter a good moment to make sure the filter is fresh. Keeping a regular maintenance schedule gives homeowners some peace of mind that the system is being looked after, and it helps support good performance and comfort through the rest of the heating season and into spring. Knowing the filter size, in this case 20x20x1, also makes it easy to stay on schedule between visits.
