There are many reasons to keep up with your furnace's air filters!
The biggest reason is to extend the life of your heating and cooling units! As dirt accumulates, air can't pass and may cause the system to overheat. The motor has to work harder. In a best-case scenario, your unit will need to be repaired. In the worst case, it may push the unit over the edge and require you to buy a new one. Replacing the filter is an easy way to lengthen the life of your heating and cooling systems.
Other reasons to keep your filters clean are to keep the air quality of your home clean, save on energy costs, and to help keep the heating and cooling systems clean.
On The Nose Home Inspections inspects about 3 to 4 dirty filters out of every 10 inspections we do! Mark your calendar, set a reminder on your phone, stick a note on the refrigerator... whatever you need to do to remind you. Always look at the instructions for the filter lifetime and schedule replacement accordingly.
