How Much Does Furnace Repair Cost in Seattle? [2025 Data]

Furnace repair costs in Seattle average $341, and most homeowners spend between $139 and $544 getting their furnaces fixed. The type of furnace and the kind of repair you need will mostly determine where in that range your total will fall, but you may also want to budget for ongoing maintenance to keep your equipment running smoothly through the long, cold winters in Seattle.

Furnace Repair Cost Factors

Some homeowners in Seattle, WA, pay as little as $97 for furnace repairs, while the most involved repairs can bring your costs up to $2,000. The parts you need are a major factor to consider, but how long the job takes will play an important role, too, because the timeline will affect your labor costs.

Repair Cost by Part

Regardless of their fuel source, furnaces are complex appliances that have a lot of moving parts. Some of those parts significantly influence furnace repair costs, while others are simpler and less costly to repair.

Here is the average furnace repair cost based on the part:

You will only find some of these parts on oil, propane, or gas furnaces, including burners, combustion chambers, flame sensors, flue pipes, gas valves, and ignitors. Since most homes in Seattle have electric furnaces, you’re less likely to run into these repairs.

Maintenance Cost

A furnace requires regular maintenance in order to operate efficiently. Otherwise, dust and other debris can clog burners, the pilot light, and other parts, causing more wear and tear on the system.

A furnace inspection costs $80 to $100 on average, and you need to schedule an inspection at least once per year to keep your system running smoothly. An advanced inspection, which includes cleaning and a tuneup, costs $125 to $200.

Additional maintenance costs include filters and air duct cleanings. You need to replace the filters once every 90 days, which will cost $4 to $140 per year. Schedule duct cleanings every three to five years, and expect to spend $275 to $500 for the cost of cleaning air ducts.

Carrying out routine maintenance on mechanical equipment is important no matter where you live, but in an area like Seattle, which sees brutally cold winters and furnaces working overtime to provide ample heat, preventative care is even more crucial.

Cost per Hour

Furnace repairs cost $50 to $150 per hour for the labor, plus you’ll need to budget for the cost of parts. Small repairs may be billed at a $100 to $200 minimum rather than by the hour.

One of the quickest repairs is to replace a dirty filter, which only takes a few minutes and is easy to DIY. Some of the more difficult, time-consuming parts to repair include the blower motor, the draft inducer motor, coils, and the heat exchanger.

HVAC Pro Costs

Depending on the specific repair you need, labor can account for anywhere from 40% to 90% of your total, which means labor for furnace repairs in Seattle will average between $140 and $310. For more involved repairs, like replacing motors or heating elements, you could pay as much as $1,000 in labor.

Labor costs in Seattle are higher than you’d pay in most other cities, primarily because the cost of living is more than 40% higher than the national average. Still, it’s worth hiring an HVAC pro in Seattle to get the job done to ensure you fix the underlying problem and that your furnace remains safe to operate.

The City of Seattle requires permits if you’re making major alterations to your existing furnace, which means you’ll need a permit for replacing major components like blower motors, heat exchangers, or coils. For these repairs, you’ll have to pay a permit fee of $56.65. If your furnace is beyond repair and you instead need to replace it, the permit fee will increase to $70.90.

Do Furnace Repairs Increase Home Value?

Furnace repairs won’t increase your home value, but they can prevent your property value from declining. Buyers who discover major faults with the mechanical equipment won’t be willing to pay as much for your home, so repairs could help you get more for your property. You’ll see a small bump in value if you replace your furnace rather than repair it in Seattle since HVAC replacement provides an average return on investment (ROI) of 30%.
