The air filter of your furnace cleans the air of dust, debris, pollen, and other contaminants. For best results, you should replace it every 60 to 90 days, or even more frequently if you smoke or have pets. Here’s why heating contractors recommend changing the filter regularly to save you money and keep your family healthy.

Why You Should Change Your Furnace Filter Regularly

Cleaner Air

The furnace filter removes contaminants that would otherwise be recirculated into the home and affect the quality of your indoor air. However, once the filter becomes dirty or clogged, pollen, pet dander, bacteria, and mold spores can sneak past and result in sneezing, coughing, sore throat, itchy eyes, and other symptoms of allergy or respiratory illness. If you don't know where the filter is or which type to buy, a heating contractor in your area can assist you.

Longer Furnace Life Span

A clogged filter impedes airflow through the furnace and forces the system to work harder than it should. Moreover, loose dust will coat the blower motor and, acting like insulation, prevent it from dissipating heat. This could lead to overheating, motor failure, and a call to a heating contractor for expensive repairs. To prevent this excess wear and tear, keep a clean filter in your HVAC system. This will permit easy airflow and keep dust from insulating the motor.

Lower Heating Costs

A dirty filter limits airflow throughout the house, as well as through the furnace itself. This means warm air cannot circulate properly, and the thermostat may not register the increased temperature as it should. This could cause the furnace to continue operating longer than needed, which results in increased gas and/or electric use and higher utility bills. To reduce your heating costs, replace the furnace filter every three months or so.
