Gresham Weather and HVAC Load
Gresham logs 4,154 heating degree days and 427 cooling degree days in a normal year, based on the closest NOAA weather station. Heating is the bigger job here. The AC still runs every summer, but it works far fewer hours than the furnace does. Count on roughly 28 nights below 32°F and 16 afternoons past 90°F in a typical year. Snowfall averages about 3 inches. On the cooling side, a 2,000 sq ft house here usually needs around 2.5 tons. A tight, well-insulated house may get by with half a ton less.

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.
Symptoms Worth a Service Call

- Water pooling around the indoor unit
- The system cycles on and off every few minutes
- The AC runs, but the air coming out is warm
What Moves the Price

- Refrigerant type and how many pounds it takes
- Whether the equipment sits in a tight attic or on a roof
- The part: a capacitor costs a fraction of a fan motor, and a compressor costs far more than both
- The service call or diagnostic fee

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
- Swap the air filter and check the breaker before you call anyone.
- Ask for the per-pound refrigerant price before any work starts.
- If you see ice, shut the system off. Running it frozen can kill the compressor.
