Hillsboro Weather and HVAC Load
In a normal year, Hillsboro racks up 4,830 heating and 275 cooling degree days (NOAA 1991-2020 normals). Heating is the bigger job here, and furnaces and heat pumps in Hillsboro put in far more hours than the air conditioner. A normal year brings 64 nights at or below freezing and 17 days over 90°F. Snowfall averages about 3 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 55,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.
| Heating degree days / year | 4,830 |

Hillsboro Housing Stock
The median Hillsboro home dates to 1997, according to the Census ACS. That makes the typical house about 29 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. About 21,000 households here own their home, 50.6% of the occupied total. Homes here have a median value of $483,400 and households a median income of $103,207. Those two numbers drive the labor adjustment in our estimate.
Washington County had 1 hail day and 1 day with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. 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.
When It Makes Sense
- Your AC needs replacing, and you'd like cheaper heat at the same time
- The house heats with electric baseboard, oil or propane
- There's no natural gas service on your street
What Moves the Price
- Size in tons, and whether the unit is cold-climate rated
- Electrical panel capacity and wiring
- A ducted system or a ductless mini-split
- Variable-speed (inverter) or single-stage compressor
- Backup heat, either electric strips or a gas furnace (dual-fuel)
We raised the national figures about 29% for Hillsboro using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.
What the Quote Should Cover

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. Plan on a mechanical permit for most replacements in Hillsboro; the contractor normally pulls it. Before you sign, ask each bidder for their Oregon license or registration number and proof of insurance. 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
- Make sure the installer sized the system for your heating load, not only cooling.
- Ask your electric utility and state energy office what heat pump rebates are open right now.
- Where winters get cold, ask for a model on the NEEP cold-climate list.

Heat Pump Installation Questions from Hillsboro Homeowners
How much is heat pump installation in Hillsboro?
Plan on $7,100 to $17,500, with most jobs near $12,800. 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 Hillsboro?
Between late spring and early fall. Hillsboro averages 64 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.
