Don't Forget to Change the A/C Filter This Summer!

    If you have to pick just one task to complete to ensure the indoor comfort and energy efficiency of your home this summer, change the A/C filter monthly.

    Airflow is a crucial parameter in any air conditioning system. The volume of air passing over the evaporator coil determines how efficiently the coil extracts heat and humidity from the interior. Airflow is also the critical factor in maintaining consistent comfort throughout all living spaces of the home.

    Because the entire volume of air in your system passes through the filter, a neglected air filter can impact almost all functions in the system. The good news is that replacing the filter is one of the tasks a homeowner can perform without an expensive service call.

    Here are some other reasons to change the A/C filter regularly this summer:

    • Filters are relatively cheap, but blower motors aren't. A dirty or clogged filter strains the air handler blower motor, one of the system's costliest components. A stressed blower motor may overheat and fail prematurely.
    • Air conditioner components like the blower and compressor running overtime in conditions they were not design for (low airflow) to meet thermostat settings are also consuming excess electricity. One of the immediate consequences of replacing a dirty filter is often a noticeable decline in utility costs. Catastrophic compressor failure is often attributable to lack of filter maintenance.{}{}
    • As the filter gets dirtier, its filtering capacity declines steadily, and your indoor air quality degrades at the same rate. Airborne particulates including allergens like mold spores, pollen and pet dander are continually recirculated in your breathing air.
    • Ductwork conveying unfiltered air accumulates excessive amounts of dust and dirt. Eventually, ductwork contamination becomes a permanent source of poor air quality that can only be resolved by expensive duct cleaning.
    • Your home's contribution to greenhouse gases and the size of its carbon footprint are directly related to HVAC system efficiency, which in turn relies on regular filter changes.
