Furnace & Heating Repair in Seattle, WA
Most Seattle furnace & heating repair jobs we see fall into 3 or 4 categories — common stuff, common fixes. Less of a mystery than the marketing makes it seem. We work clean, leave the area better than we found it, and stick around to test the repair before we drive off.
The actual work
Heating-side repairs run different than AC. Most furnace calls come down to ignitor failure, flame sensor, control board, or pressure switch. Heat pumps add reversing valve and defrost board.
Gas furnace ignitor failures are the most common winter call — about 40% of no-heat calls. The ignitor is a $35 part and a 20-minute job; total flat-rate runs $185-$340.
Heat pump no-heat in cold weather usually means failed reversing valve solenoid (system stuck in cool mode) or failed defrost board (outdoor coil iced up). Both diagnoseable in under an hour.
Older furnaces (15+ years) develop heat exchanger cracks. We check for them every diagnostic visit because a cracked heat exchanger leaks carbon monoxide and is a replacement-not-repair issue.
Notes on Seattle housing stock
We dispatch from a shop near the city limits, so Seattle runs are quick. Suburbs and outlying towns run longer.
That said, newer construction in Seattle has its own set of typical issues. We see both.

One we ran last year
Recent Seattle job: heat pump blowing cold air in 28°F weather in a 8-year-old home. We replaced solenoid coil, recommissioned after diagnosing failed reversing valve solenoid. Cost ran $2275 — pretty middle-of-the-road for that fix.
