How Much Does a Furnace Tune-Up (and Emergency No-Heat Repair) Cost in Seattle? (2026 Guide)

Quick answer

A professional furnace tune-up in the Seattle area usually costs $125 to $200 in 2026. An emergency no-heat visit comes in two pieces. First there’s a trip or diagnostic fee. Angi puts typical service call fees at $100 to $250 nationally, and most contractors charge more after hours. Then there’s the repair, which runs $139 to $544 for most Seattle homes and averages about $341 (Angi, August 2026). The part itself is rarely what drives the bill up. The timing is.

How much does a furnace tune-up cost in Seattle in 2026?

Across the Seattle area, a professional furnace tune-up runs $125 to $200, depending on who you hire and what the visit covers. That’s the full tune-up range in Angi’s August 2026 Seattle data. A basic inspection runs $80 to $100, and some established local companies list their tune-ups above $250. Why such a wide range? Nobody regulates the word “tune-up.” A $90 visit might be a new filter and a quick look at the burners. A real combustion and safety tune-up, the kind that keeps you from calling us in January, should cover all of this:

Every Home Comfort Alliance furnace tune-up covers that full checklist, priced within the local range, and Comfort Club members save on maintenance. If you’re comparing quotes, ask each company for its checklist, not just its price. A tune-up that skips the heat exchanger and flame sensor isn’t a better deal. It’s an unfinished one.

How much does emergency furnace repair cost in Seattle?

An emergency furnace repair in Seattle usually means a trip fee (typically $100 to $250, per Angi national data) plus $139 to $544 for the repair, about $341 on average (Angi, August 2026). Add those together and a typical emergency visit lands around $440 to $590, nearly three times what a preseason tune-up costs. Here’s how those two parts break down.

1. The trip fee (diagnostic)

This is what you pay to get a technician to your door and find the problem. Most contractors charge more at night, on weekends and on holidays, so ask for the after-hours rate before anyone is dispatched. Ours is $119 during standard hours, with after-hours rates starting at 6 p.m., quoted upfront. You’ll get a price for parts and labor before any repair work starts.

2. The repair

According to Angi’s Seattle data from August 2026, a typical furnace repair costs $139 to $544. The average is $341, and major components can push it close to $2,000. Here’s what the common repairs cost in Seattle, parts and labor included, along with whether a tune-up usually spots the problem first:

Three things usually push a repair past $500. One is a part that has to be special-ordered for an older furnace. Another is a failure that takes a second component down with it, like a seized inducer that fries the control board. The third is timing. If it’s 8 p.m. on a Friday in the middle of a freeze, you’re paying the after-hours rate on the same night the whole region is calling for help.

What to do if your heat goes out tonight

Before you pick up the phone, run through these five checks. They fix a surprising number of the “no heat” calls we get.

1. 1Thermostat. Make sure it’s set to HEAT and the temperature is set higher than the room. If it runs on batteries, swap them out.
2. 2Breaker and switch. Check the furnace breaker in your electrical panel, plus the power switch on or near the furnace (it looks like a regular light switch). Both get flipped by accident all the time.
3. 3Filter. A badly clogged filter can trip the furnace’s high-limit switch. Pull it out and hold it up to the light. If no light gets through, replace it.
4. 4Gas supply. If you have gas, check whether your other gas appliances (stove, water heater) still work. If you smell gas, leave the house right away, then call Puget Sound Energy at 1-888-225-5773 or 911. Call them before anyone else, including us. If you’re not sure whether a smell is a problem, our guide to which furnace smells are normal and which are dangerous explains what to look for.
5. 5Condensate drain and outdoor vents. High-efficiency furnaces shut down when the PVC drain freezes or clogs, or when snow blocks the intake or exhaust pipe outside. Clear them and try again.

Still nothing? Pay attention to what the furnace is doing. Is it clicking without lighting, starting up and shutting off, blowing cold air, or doing nothing at all? Tell the dispatcher when you call. It helps us show up with the right parts.

Don’t wait for an outage to do checks 3 and 5. Swapping the filter and clearing the outdoor intake and exhaust vents before winter prevents many of these shutdowns.

When should you repair a furnace vs. replace it?

Here’s the rule of thumb most of us use in the field. If the furnace is more than 12 to 15 years old (about how long a furnace lasts around here) and the repair would cost more than roughly a third of a new one, replacing it is usually the smarter spend. A new gas furnace installed in the Seattle area runs $4,000 to $8,000. Our furnace installation cost guide breaks that number down, and this guide on stacking PSE and Washington HEAR rebates can bring it down.

The clearest case for replacing instead of repairing is a cracked heat exchanger on an older furnace. A new heat exchanger can run up to about $1,620 in Seattle, which rarely makes sense at that age. And the furnace shouldn’t run at all until the crack is dealt with. If you’re on the fence, we’ve written more about making the repair-or-replace call.
