Frequently Asked Questions

How often should the cabin air filter be replaced?

Every 12,000–15,000 miles or once a year. In Hillsboro and the Willamette Valley, we’d suggest replacing it before pollen season in spring, and again if you drove through wildfire smoke season without replacing it.

Will replacing the cabin air filter fix the musty smell in my vents?

Often yes — especially if the smell started gradually over time. If the smell persists after replacement, mold may have grown on the HVAC evaporator core, which requires a separate cleaning service.

What’s the difference between a regular cabin filter and an activated carbon filter?

A standard filter captures particles — pollen, dust, debris. An activated carbon filter also absorbs gases, odors, and exhaust fumes. For allergy sufferers or anyone who wants to reduce odors from traffic or smoke, the carbon upgrade is worth the small price difference.

My AC airflow feels weak. Could the cabin filter be the problem?

Yes — a heavily clogged filter significantly restricts HVAC airflow. It’s one of the most common and cheapest causes of reduced AC performance. Replace the filter before spending money on HVAC diagnostics.

Do you service all makes and models?

Yes — all vehicles, gas and diesel, trucks and daily drivers. Hillsboro, Beaverton, and Portland metro.
