How often should I change my HVAC air filter?

Standard 1-inch filters should be changed every 30–90 days. Homes with pets or allergies should change them monthly. 4-inch media filters last 6–12 months.

What MERV rating filter should I use?

For most homes, MERV 8–11 provides a good balance of air quality and airflow. Higher ratings capture more particles but can restrict airflow if your system isn't designed for them. We can recommend the right rating for your system.

Can the wrong air filter damage my HVAC system?

Yes. A filter that's too restrictive reduces airflow, which can cause frozen coils, overheated motors, and premature equipment failure. Always use the filter type and size recommended for your specific system.

Standard HVAC Air Filters

Every forced-air HVAC system uses an air filter to protect the equipment and improve indoor air quality. We recommend replacing standard 1-inch filters every 30–90 days depending on household factors: homes with pets, allergies, or smokers should change filters more frequently. We carry a range of filter sizes and MERV ratings to fit your system.

Upgraded Filtration Options

For better air quality, consider upgrading to a higher-MERV filter, a 4-inch media filter cabinet, or a whole-home air purification system. Higher MERV ratings (MERV 11–16) capture smaller particles including mold spores, bacteria, and fine dust. Media filter cabinets hold larger, more effective filters that last 6–12 months between changes.

Whole-Home Air Purification

For the highest level of air quality, we install whole-home air purifiers and UV light systems that work with your existing HVAC to neutralize bacteria, viruses, mold, and volatile organic compounds. These systems are especially beneficial for allergy and asthma sufferers.

Filter Selection Matters

Using the wrong filter can damage your HVAC system. Too restrictive a filter (very high MERV) can reduce airflow, strain your blower motor, and cause the evaporator coil to freeze. Our technicians can recommend the optimal filter for your specific system — balancing air quality with proper airflow.
