Air Filters...

So, our last poll asked what is the purpose of air filters? 60% said to keep the air clean, 40% said to keep the coils clean. The correct answer is to keep the coils clean.

Although air filters do help limit the amount of dust that gets into the air, the real purpose is to keep the coils that heat and cool clean. When coils are clean, buildup of dust and debris does not inhibit the heating or cooling properties of the unit thus causing heating or cooling issues in the building. When the coils remain clean, your HVAC unit runs very efficiently and does not cause unnecessary repairs or problems for the building and its occupants. So, change your air filters regularly for a well-maintained heating unit.
