Our furnace tune-up is $230, or $180 for Home Comfort Club members (prices as of September 2026). Oil furnace tune-ups are $336, or $288 for members. For comparison, Angi’s national cost guide puts a furnace tune-up at $130 to $200 (July 2026). An emergency no-heat visit comes in two pieces. First there’s the visit: our dispatch fee is $119, a standard diagnostic is $72 and a deeper diagnostic is $130, and qualifying after-hours emergencies carry a $330 after-hours fee. 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.

After 26 years of service calls around Seattle, here’s what I’ve learned: the cold snap doesn’t create the problem. It exposes it. Even a mild winter brings a hard freeze, and furnaces with a worn igniter or dirty flame sensor are the first to quit. Most show signs they’re about to fail months earlier. Here’s what it costs to get ahead of that in 2026, and what it costs if you don’t.
How much does a furnace tune-up cost in Seattle in 2026?
A furnace tune-up with Home Comfort Alliance is $230, or $180 for Home Comfort Club members (prices as of September 2026). Oil furnace tune-ups are $336, or $288 for members. That is the price for one furnace; each piece of equipment is priced on its own. For comparison, Angi’s national cost guide puts a furnace tune-up at $130 to $200 (July 2026). Prices vary because nobody regulates the word “tune-up.” A cheap visit might be a new filter and a quick look at the burners. Ask any company what its tune-up covers. Ours covers all of this:
Full tune-up checklist
- Controls and safety: thermostat operation, motors and controls, wiring and safety controls.
- Combustion and venting: flue and piping, gas pressures and burner assemblies.
- Airflow and the cabinet: indoor equipment, blower belt, supply and return temperatures, the cabinet, and the condensate pump where your furnace has one.
- Final check and records: a final operation test, and service records we keep for warranty validation.
Every Home Comfort Alliance furnace tune-up covers that checklist, 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.

The house that calls us in October for a tune-up and the house that calls us in January with no heat usually have the same furnace. In October, it’s a quick fix on a small part. By January, that same part has often failed and taken something bigger down with it.

How much does emergency furnace repair cost in Seattle?
Angi’s Seattle data (August 2026) puts a typical furnace repair at $139 to $544, about $341 on average. Our fees are listed separately: a $119 dispatch fee during standard hours, a $72 standard diagnostic, and a $330 after-hours dispatch fee for qualifying emergencies such as no heat in cold weather. You get a price for the repair before any work starts. For part-by-part prices, see our furnace repair cost guide, and for a no-heat night, our emergency furnace repair page.
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.
- 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.
- 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.
- 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.
- 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.
- 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.

Frequently asked questions
How much is a furnace tune-up in Seattle?
Our furnace tune-up is $230, or $180 for Home Comfort Club members (prices as of September 2026); oil furnace tune-ups are $336, or $288 for members. For comparison, Angi’s national cost guide puts a furnace tune-up at $130 to $200 (July 2026). Ask any company for its checklist, not just its price.
How much does an emergency furnace repair cost in Seattle?
You’ll pay a trip or diagnostic fee, typically $100 to $250 according to Angi’s national data (our dispatch fee is $119 during standard hours, or $330 after hours for qualifying emergencies), plus the repair itself. For most Seattle homes the repair runs $139 to $544 (Angi, August 2026).
Is a furnace tune-up worth it?
For a gas furnace, yes. A tune-up catches the two most common no-heat failures, the flame sensor and the igniter, and it includes a heat exchanger check for carbon monoxide risk. Many manufacturer warranties also require proof of yearly maintenance.
When is the best time to schedule a furnace tune-up in Seattle?
September through early November, before the first cold snap. Once overnight lows drop into the 20s, wait times go up fast.
How often should a furnace be serviced?
Once a year for a gas furnace. Heat pumps that also cool your home should be serviced twice a year, once in fall and once in spring.
Is a tune-up different for an electric furnace or heat pump?
Yes. With no combustion to test, the visit focuses on the heating elements, sequencers, blower and airflow instead. It’s a different checklist with the same goal. Not sure which you have? Here’s how a gas furnace compares to an electric one, and what we do for heat pump repair and service.
Will Seattle have a cold winter in 2026 to 27?
Probably not a cold one overall. NOAA’s winter outlook, issued Sept. 17, 2026, favors a warmer-than-normal winter for the Northwest as a strong El Niño builds. But in Seattle the real furnace risk is a short arctic blast, and those can hit even in a mild winter. The January 2024 cold snap came during the last strong El Niño winter.
What does a furnace trip fee cover?
It covers getting a technician to your home quickly and figuring out what’s wrong. Parts and repair labor are quoted separately before any work begins.
Do HVAC companies charge more for after-hours furnace repair?
Almost all of them do, especially for evening, weekend and holiday calls. Ask for the after-hours rate before anyone is dispatched. At Home Comfort Alliance, we quote it upfront, before a technician is sent.
