Every city has its own failure patterns, and Seattle is no exception. On service calls here we see a lot of igniter failures on furnaces that sit unused through our long mild falls, then get pushed hard the first time temps drop into the 30s. We also see condensate line clogs from Pacific Northwest humidity and heat pump outdoor units icing over during damp, near-freezing stretches instead of true cold snaps.
Local knowledge
What's different about heating repair in Seattle
Every area we serve is different — in Seattle, these three factors matter most.
Seattle's housing stock skews older in neighborhoods like Ballard, Wallingford, and Ravenna, where original crawlspace furnaces and ductwork from the 1950s-70s are common and prone to rust and air leaks from ground moisture.
PSE supplies electricity and gas to most of Seattle, and we size repair recommendations around PSE's rate structure so homeowners understand real running costs before approving a fix.
Seattle's mild, wet winters mean heat pumps run in defrost mode often; when drainage or refrigerant charge is off, ice builds on the outdoor unit and homeowners lose heat exactly when they need it most.

Straight answers
Heating Repair in Seattle — FAQ
Why did my furnace suddenly stop working the first cold week of the year?
This is one of the most common calls we get in Seattle. Furnaces sit idle through our mild September and October weather, and the igniter or flame sensor fails the moment the system finally has to run continuously in November or December.
Why does my heat pump ice over instead of heating my Seattle home?
Our damp climate means heat pumps cycle into defrost mode more often than in drier regions. If the defrost board, sensor, or refrigerant charge is off, ice builds faster than the unit can clear it, and heat output drops.
Is heating repair different for older Seattle homes versus newer construction?
Yes. Homes built before 1980 in areas like Ballard or Ravenna often have original crawlspace ductwork with leaks or rust that newer systems in Bellevue or Sammamish homes don't have, so repairs sometimes involve duct sealing along with the unit fix.
How fast can someone get to my house in Seattle?
Most Seattle, Bellevue, Redmond, Kirkland, and Issaquah appointments are scheduled within 48 hours, and we prioritize no-heat calls the same day when possible, especially during cold snaps.
