Furnace Repair in Puyallup: Costs and Repair or Replace
Most furnace repairs cost between $133 and $505, with a national average of $318. A new ignitor or flame sensor runs $150 to $500. If a repair costs more than half the price of a new furnace and the unit is past 10 years old, start pricing replacements.
The furnace always quits on the coldest morning of the year, and the first quote you hear always sounds high. Knowing the normal price range before you make the call puts you in a much better spot.

HomeAdvisor's average is $318, with a normal range of $133 to $505. Labor runs $50 to $150 an hour, and most companies charge a trip fee equal to at least one hour. Budget extra for nights, weekends, and holidays.
Check these before you call
A surprising number of service calls end in five minutes. Rule out the easy ones first.
- Thermostat. Set to heat, set above room temperature, and fresh batteries.
- Filter. A clogged filter makes a furnace overheat and shut itself off. Replace it.
- Breaker and switch. Check the breaker panel and the light-switch-style shutoff near the furnace.
- Furnace door. A door that is not fully seated trips a safety switch.
- Vents. Make sure supply and return vents are open and not blocked by furniture.
- Outside intake and exhaust. On high-efficiency units, check the plastic pipes outside for leaves or nests.
If you smell gas, do not troubleshoot. Leave the house and call your gas utility from outside.
Repair or replace?
HomeAdvisor's guidance is the 50% rule: if the repair quote is more than half the cost of a new furnace and the unit is around 10 years old or more, compare replacement options. Furnaces typically last 15 to 30 years.
| Situation | Usually |
|---|---|
| Under 10 years old, small part failed | Repair |
| 10 to 15 years old, moderate repair | Repair, and start budgeting |
| Over 15 years old, expensive repair | Replace |
| Cracked heat exchanger | Replace. This is a safety issue |
| Repairs every winter | Replace |
Be careful with a cracked heat exchanger diagnosis. It is serious when true, and it is also the classic upsell. Ask to see the crack, and get a second opinion before spending thousands.
If you are replacing, look at heat pumps
Puyallup winters are mild enough for a heat pump to do most or all of the heating, and you get air conditioning from the same equipment. Puget Sound Energy lists heating rebates for heat pump conversions and upgrades, with higher amounts for income-qualified customers. I go through pricing in my post on heat pump installation costs.
Permits
Replacing a minor part does not need a permit. Pierce County's Work Exempt from Building Permit guide lists the replacement of minor parts that do not affect a unit's approval or safety as exempt. Installing a new furnace is different. Expect a mechanical permit from the city or county, and your installer should pull it.
Hiring a heating contractor
- Look the company up in the state's Verify a Contractor tool.
- Ask for the diagnosis and the price in writing before work starts.
- Ask what the trip fee is and whether it is credited toward the repair.
- For a replacement, get three bids. That is the state's own recommendation for hiring a contractor.
Maintenance that prevents most repairs
- Change the filter every one to three months during heating season.
- Have the system serviced once a year, ideally in early fall before the rush.
- Keep the area around the furnace clear.
- Test your carbon monoxide alarms.
Why this matters when you sell
Heating is on every buyer's inspection report. An old furnace with no service history gets written up as "near end of life, budget for replacement," and buyers ask for a credit.
A recent service receipt changes that conversation. It costs about the same as a repair call and it is one of the best things you can hand a buyer. If the furnace is truly at the end, it is better to know before you list than to find out during negotiations.
