What Your HVAC Contractor Wants You to Know About Air Filters
When it comes to caring for your home heating and air conditioning, you typically rely on an HVAC contractor to provide maintenance and repair work. However, part of keeping your system in good condition requires that you do a little work yourself. With proper air filter maintenance, you can avoid unnecessary air conditioner and furnace repair and keep your system functioning at top efficiency.
HVAC Filter FAQ
What do air filters do?
Air filters are designed to trap air particulates to keep them from circulating through your HVAC system and indoor air. Particles such as dust, hair, pollen, and even mold spores get trapped in the filters when air is forced through the filter while the HVAC system is operating.
What types of filters are there?
HVAC filters are typically made from fiberglass and distinguished by the MERV rating. MERV ratings indicate how effectively the filter removes airborne contaminants, with 1 being the lowest and 16 being the highest. Most household air filters have a MERV rating of 6 to 8.
Where do the filters go?
Filters typically don’t go in the HVAC equipment itself. Rather, they go in the home’s return vents. These vents suck air in when the HVAC system is operational, and have a large metal grate in front. The filter goes behind the grate.
How often should you replace your filter?
Most households should replace HVAC air filters every 90 days. However, certain factors like having pets, smoking, or living in a dusty environment may require that you replace filters more frequently, such as every month. If you’re unsure, your HVAC contractor can give more specific recommendations for your home.
