When the cold rolls in, we rely on our furnace to keep us warm. When was the last time you thought about the condition of your furnace’s filter when you reached for your thermostat? Never fear! We’re here to take the guesswork out of this important upkeep.
What Does a Furnace Filter Do?
The short answer is that it improves the air quality in your home or business. It does this by trapping airborne contaminants and filtering them out of the air you breathe. Just as important, it keeps those same particles out of your heating and cooling system. This improves the machine’s function and can extend its life, saving you thousands on a replacement.How Often Should Filters be Replaced?
Many factors go into the ideal replacement schedule for each home or business. For most furnaces, the rule of thumb is no more than three months between new filters. Some filters should be changed every 30-60 days. Certain circumstances will require you to replace your filter more often.- The size of your filter. Smaller filters, 1-2 inches thick, need to be replaced more often.
- How much traffic you have. A busy business or large family needs to have their filters changed more often. People introduce contaminants to your space that need to be filtered out. More people equals a dirtier filter.
- Pets. Furry friends add a lot of stress to furnace filters because hair and dander build up quickly.
- High usage. If you run your heating and cooling system all the time, your filters need to be changed more often to keep up with demand.
