Gresham Housing Stock
Half the homes in Gresham were built before 1981 (Census ACS median), so the typical house is about 45 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Owners live in 56.1% of occupied homes, roughly 24,000 households. Homes here have a median value of $440,000 and households a median income of $73,608. Those two numbers drive the labor adjustment in our estimate.
Between 2020 and 2025, NOAA's Storm Events Database logged 2 days with damaging thunderstorm winds in Multnomah County. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost.

Oregon Licensing and Efficiency Rules
Oregon falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Oregon the company should carry a state license or registration. Ask for both.
Before You Hire
- Light frost on the outdoor unit in winter is normal. A solid block of ice is not.
- Many heat pumps carry a 10-year parts warranty if they were registered. Find out whether yours was.
- Keep two feet clear around the outdoor unit, including snow.

Heat Pump Repair Questions from Gresham Homeowners
What does heat pump repair cost in Gresham?
Most bills land between $200 and $960, including the service call. A typical visit is about $620. Night and weekend calls cost more.
Is it normal for a heat pump to freeze?
A thin layer of frost in winter is normal, and the defrost cycle should clear it. Heavy ice that stays usually means a defrost control or airflow problem.
Why is my heat pump blowing cold air?
For a few minutes during a defrost cycle, that's normal. If it keeps going, the usual causes are a stuck reversing valve, low refrigerant or a thermostat set to the wrong mode.
