Nobody budgets for a heat pump repair. It shows up on a Tuesday in January, the house is sitting at 61 and dropping, and the first question out of every homeowner's mouth is the same one: what is this going to cost me?
Here is the honest version, from a Federal Way crew that does this work across King, Pierce and Thurston counties. No scare tactics, no manufactured urgency — just the money math.
The short answer, and why it's a range
Heat pump repairs in our service area run:
| Market | Typical repair range |
|---|---|
| MarketStandard (most of the service area) | Typical repair range$150 – $1,500 |
| MarketAffluent (Seattle, Maple Valley, Normandy Park, Black Diamond, Steilacoom, Fircrest) | Typical repair range$175 – $1,800 |
| MarketLuxury (Bellevue, Gig Harbor, Fox Island) | Typical repair range$200 – $2,000 |
That's a ten-to-one spread, which is useless to you without context. So let's break down what actually decides where in the range your repair lands.
The three things that move the number
What broke
This is 80% of it. Heat pumps fail in a predictable order, and the cheap failures are far more common than the expensive ones. A small electrical component sitting outside the sealed refrigerant circuit is a bottom-of-the-range job. Anything that requires opening the refrigerant circuit — recovering charge, brazing, pulling a vacuum, recharging — is a top-of-the-range job, because it takes hours, licensed handling and specialized equipment.
How old the system is
Age doesn't change the labor rate, but it changes parts availability and whether the part is still under manufacturer warranty. A five-year-old system with a registered warranty may only cost you labor. A 16-year-old system running R-22 may need a part that's been discontinued, and R-22 itself is phased out and expensive when you can get it at all.
Where the house is
Our pricing tiers track market, not distance. A repair in Bellevue or Gig Harbor sits in the luxury tier; most of the I-5 corridor sits in the standard tier. Coastal homes in Des Moines, Burien, Steilacoom, Tacoma and Gig Harbor also carry a real corrosion factor — salt air chews on outdoor coils, fan hardware and electrical connections faster than inland air does, which pushes those homes toward repairs sooner.

Notice the pattern: the components most likely to fail are also the cheapest to fix. That is genuinely good news, and it is the opposite of what a high-pressure salesperson wants you to believe when they walk in the door talking about a whole new system before they've opened a panel.
Check the free stuff before you pay anybody
We would rather you save the diagnostic fee than call us for something you can fix in four minutes. Run this list first:
- Thermostat mode. Set to HEAT, not EM HEAT or ON. Emergency heat is expensive electric backup, and running it all winter is a real budget problem.
- The breaker. Heat pumps have two — one for the indoor air handler, one for the outdoor unit. Both need to be on.
- The filter. A packed filter starves airflow and can trip safety limits. This is the single most common cause of "my system stopped working."
- Clearance around the outdoor unit. Blackberry, fir needles, bark, a stack of firewood. Give it two feet of breathing room on all sides.
- Steam is normal. A heat pump venting steam in winter is running its defrost cycle. A solid block of ice for hours is not normal.
If those all check out, the problem is real. Our heat pump not heating walkthrough covers the symptom-by-symptom logic in more depth.
When repair stops making sense
This is where honesty either costs us a sale or earns your trust. Both are fine.
Repair it when: the system is under roughly 10 years old, the repair costs less than half of a replacement, the refrigerant is R-410A or newer, and it's the first significant failure. That's most of the calls we run.
Replace it when: the system is 12 to 15-plus years old, you're facing a four-figure sealed-system repair, it runs R-22, or this is the second real repair in two years. Replacement in standard markets runs $10,000 to $16,000, and a full ducted installation runs $12,000 to $18,000 — with a 10-year parts and labor warranty on our side of it, which resets the whole conversation.
There's also a rebate angle worth knowing. Up to $4,400 is available toward a qualifying heat pump when it replaces an existing electric or fossil-fuel system; the exact amount depends on what you're replacing and what you install. Programs change, so we confirm your current eligibility and handle the paperwork. One thing that does not change: from April 2, 2026, PSE rebates require a PSE-certified installer. We are PSE certified. And the federal 25C tax credit ended December 31, 2025 — anyone still advertising it is selling you a number that doesn't exist.
Rebate eligibility also follows the name on your power bill, not your county line. Tacoma, Fircrest, University Place and Fife are Tacoma Power. Seattle is City Light. Gig Harbor and Fox Island are Peninsula Light. We check your address before quoting a rebate figure.
Two ways to keep this bill smaller
- Maintain it. Semi-annual service on coastal homes, annual inland. Clean coils, tight electrical connections and correct charge prevent most of the mid-range failures on that table.
- Don't pay twice for the same problem. A refrigerant top-off without a leak search is money you will spend again by spring. Refrigerant does not get used up. If it's low, it left.
Get a real number
We diagnose, we price it in front of you, and if the smarter call is a repair instead of a replacement, we'll say so — several of our reviews exist for exactly that reason. Service hours are Monday through Friday, 8 to 6, with same-week scheduling in most of the service area.
