If you have a heating and cooling system, you have air filters. An air filter's primary job is to prevent large airborne particles from entering or clogging your HVAC system. Some air filters do also do the job of preventing certain allergens and pollutants from recirculating throughout your home's duct system, however that is not their main role.
Temperatures in Richmond will soon be dropping. For most of us, our air conditioners and heat pumps are grateful for the break. They worked over time this summer - intaking air and disbursing colder air. All that air has to pass through out air filters which by now have had time to accumulate dust, pollen, mold and other particles from your home’s air.
There’s nothing quite like receiving your first round of utility bills during the peak of summer. Does your bank account feel emptier? You can ease the shock by investing in a programmable thermostat if you haven't already. They're easy to install and you can start saving right away!
