Frequently Asked Questions

How often should I have the vehicle HVAC system inspected?

Once a year, ideally before the season you rely on it most. In Oregon, that means a heater/defroster check in September–October and an AC check in May. Most HVAC issues develop gradually over a full season.

My AC is blowing air but it’s not very cold. What’s wrong?

Most likely low refrigerant from normal annual loss, a failing compressor clutch, or a clogged cabin air filter reducing airflow. We’ll test refrigerant pressure and component function to determine which one.

My windshield fogs on the inside every cold morning. Is that a problem?

Some morning fogging is normal from interior moisture. If it’s persistent, heavy, or accompanied by a sweet smell from the vents, it may indicate a heater core leak. The heater core circulates hot coolant behind the dash — a small internal leak releases coolant as vapor that condenses on the glass.

My heater works fine but only blows at full power. What causes that?

A failed blower motor resistor. The resistor controls fan speed at lower settings. When it fails, only the full-power circuit remains functional. It’s a relatively inexpensive repair on most vehicles.

Do you service all makes and models?

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