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, and furnaces and heat pumps in Gresham put in far more hours than the air conditioner. Count on roughly 28 nights below 32°F and 16 afternoons past 90°F in a typical year. Snowfall averages about 3 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 50,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

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.

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
- Check the filter, the thermostat batteries and the breaker first. Those three cause a surprising number of no-heat calls.
- Have the model and serial number from the furnace label handy. Parts get ordered faster.
- Ask whether the diagnostic fee comes off the repair bill.
