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.
Symptoms Worth a Service Call
- The outdoor unit hums, but the fan doesn't spin
- Ice on the refrigerant lines or the indoor coil
- The system cycles on and off every few minutes
- Water pooling around the indoor unit
- The AC runs, but the air coming out is warm
What Moves the Price
- The service call or diagnostic fee
- Whether the equipment sits in a tight attic or on a roof
- Refrigerant type and how many pounds it takes
- The part: a capacitor costs a fraction of a fan motor, and a compressor costs far more than both
- Nights, weekends and holidays

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. A repair usually goes ahead without a permit, but the tech handling refrigerant must hold EPA 608 certification. Ask the company for its Oregon license or registration number before the visit.
Before You Hire
- If the compressor is gone on an older unit, get a replacement quote before you pay for the repair.
- Ask for the per-pound refrigerant price before any work starts.
- Swap the air filter and check the breaker before you call anyone.
