You may be wondering just how important it is to change the filter in your furnace. As someone who’s been in the industry for more years than I care to admit, I can tell you it’s very important. In fact, changing the filter is the No. 1 thing a homeowner can do (without calling a professional) to maintain their furnace.
In most cases, it’s not that homeowners choose not to change the furnace filter; it’s that they don’t know they’re supposed to change it. That’s why every time Bell Brothers installs a furnace in a home, the technician will show the homeowner how to change the filter.
