Heat pump repair in Seattle runs $250 to $1,800 depending on the part and the fix. SPS Pro Services dispatches licensed techs across King County, and most Seattle calls get a same-day or next-day appointment window with a two-hour heads-up call before the tech arrives.

AvailabilitySame-week visits
HoursMon–Fri 8am–6pm
When your heat pump stops heating or starts blowing cold air, you want a real appointment window, not a vague all-day promise. We book Seattle repair calls into two-hour arrival slots, text you when the tech is on the way, and stock common heat pump parts, including capacitors, contactors, and defrost boards, on the truck so most units are back running the same visit. Expect a diagnostic first, then a written price before any repair starts.
Local knowledge
What's different about heat pump repair in Seattle
Here is what our techs actually see on Seattle jobs, season after season.
Seattle City Light serves electric power inside city limits while Puget Sound Energy handles natural gas, so many Seattle heat pumps run in dual-fuel setups paired with a gas furnace, and a wrong switchover setting is a frequent cause of high bills we get called out for.
A lot of Seattle housing stock in neighborhoods like Ballard, Wallingford, and Rainier Valley predates 1980, with ductwork sized for the original furnace rather than the heat pump added later, which shows up as airflow-related lockouts and fault codes.
Damp Pacific Northwest winters keep outdoor units cycling through defrost constantly, and when a defrost sensor, board, or condensate drain fails, ice builds up on the coil, which is one of our most common no-heat calls from November through February.

How a Seattle heat pump repair visit works
1
Call or Book Online
Tell us the heat pump's make and model if you have it, and what it's doing wrong. We confirm a two-hour arrival window on that same call.
2
On-Site Diagnostic
The tech checks refrigerant pressures, electrical components, the defrost cycle, and airflow through the ducts to find the actual failure point.
3
Written Estimate Before Repair
You get a flat price for the fix, based on the $250 to $1,800 range for that type of repair, before any work starts.
4
Repair From Truck Stock
Most Seattle heat pump repairs use parts already on the truck, such as capacitors, contactors, thermostats, and defrost boards, so the fix usually happens the same visit.
5
Test and Walkthrough
We run the system through a full heating cycle, check thermostat settings, and explain what failed and how to avoid a repeat call.

Straight answers
Heat Pump Repair in Seattle — FAQ
How fast can someone get to my house in Seattle?
Most Seattle requests get a same-day or next-day two-hour arrival window, depending on how full the schedule is when you call. Weekday mornings tend to have more open slots than Friday afternoons, especially during the first cold snap of the season when call volume rises across King County.
Why does my heat pump ice up during Seattle winters?
Pacific Northwest humidity keeps outdoor units running defrost cycles often. If a defrost sensor, board, or drain line fails, ice builds up on the coil and the system stops heating. This is one of the most common repair calls we get in Seattle between November and February.
My house has an older gas furnace plus a heat pump. Can you work on that?
Yes. Dual-fuel setups are common in older Seattle homes where a heat pump was added onto an existing gas furnace. We check the switchover control and thermostat settings, since an incorrect setting is often why homeowners see unexpectedly high electric or gas bills.
Do you charge extra for the diagnostic if I don't repair the same visit?
There's a diagnostic fee for the visit itself. If you move forward with the repair that day, that fee applies toward the total cost, which typically falls between $250 and $1,800 depending on the part needed.
