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.

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 Permits, Efficiency Rules and Rebates
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. Equipment replacements in Gresham generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Oregon license or registration number and a certificate of insurance with the quote. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Where winters get cold, ask for a model on the NEEP cold-climate list.
- Ask your electric utility and state energy office what heat pump rebates are open right now.
- A dual-fuel setup keeps your gas furnace as backup for the coldest nights.

Heat Pump Installation Questions from Gresham Homeowners
How much is heat pump installation in Gresham?
Plan on $6,200 to $15,200, with most jobs near $11,200. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule heat pump installation in Gresham?
Between late spring and early fall. Gresham averages 28 freezing nights a year, and heating calls spike from November through February.
How long does a heat pump last?
Usually 12 to 15 years. A heat pump runs year-round, so it needs maintenance twice a year rather than once.
Do heat pumps work in cold weather?
Yes. Cold-climate heat pumps keep making heat well below 0°F. They lose efficiency as it gets colder, so many homes in cold regions keep backup heat.
