HVAC Cost Breakdown (2026)
These are the ranges we see across Seattle, from Ballard to Rainier Valley to West Seattle. Parts and labor are included unless noted.
| Service | Typical Seattle Range | Notes |
|---|---|---|
| AC repair | $175 – $765 | Covers most single-part fixes, from capacitors to fan motors |
| Furnace repair | $175 – $825 | Igniters, blower motors, control boards, and sensors |
| AC installation | $4,130 – $8,850 | Full system replacement, including labor and refrigerant |
| Tune-up | $95 – $235 | Annual maintenance for one system; seasonal rates vary |
A few common line items break out like this. A furnace igniter runs $150 to $300 parts and labor included. A blower motor replacement lands $400 to $700. An AC capacitor is usually $175 to $350, which is why it’s one of the more affordable fixes we do. A refrigerant recharge, which means refilling the fluid that moves heat out of your home, typically runs $250 to $600 depending on how much is needed and the type of refrigerant.
What drives the price up? Multiple failing parts on an older system, hard-to-reach equipment, and refrigerant type. What drives it down? Catching a small problem early, keeping up with tune-ups, and having a system that’s still under its manufacturer’s parts warranty. A repair on a well-maintained furnace almost always costs less than one on a system that’s been ignored for a decade.
What Affects HVAC Pricing in Seattle
- System age. A furnace past 15 years often needs a bigger repair than a five-year-old unit, and parts get harder to source. In older Seattle neighborhoods like Wallingford and Fremont, we regularly see furnaces that have outlived their expected life.
- Refrigerant type. Older AC systems use R-22, which is no longer produced and costs far more per pound than the R-410A used in newer equipment. If your system uses R-22, a recharge will run higher.
- Access and layout. A unit in a tight crawlspace or a rooftop condenser in a Capitol Hill condo building takes more time to reach than a basement furnace with clear space around it. Labor follows access.
- Time of year. The first cold snap in November or the first warm stretch in July brings a rush of calls. Scheduling a tune-up in the shoulder seasons, spring and fall, is almost always cheaper and faster.
- Emergency vs. scheduled. After-hours calls, especially on a holiday weekend, cost more than a Tuesday morning appointment. We answer the phone 24/7 either way, but a scheduled visit stays in the standard range.
- Rebates and incentives. Seattle City Light and Puget Sound Energy both offer programs that can offset the cost of a high-efficiency heat pump or furnace. Ask about current incentives before you commit to a replacement.
How to Save on HVAC
The single biggest saver is a yearly tune-up. At $95 to $235, it costs a fraction of a repair, and it catches the worn capacitor or dirty flame sensor before it turns into a no-heat night in January. Seattle’s damp climate is hard on outdoor condensers, so a spring cleaning of the coils and a fall check of the furnace pay for themselves.
Other ways to keep the bill down:
- Change your filter every 1 to 3 months. A clogged filter makes the blower work harder and shortens its life.
- Schedule repairs before they become replacements. A $300 fix now can delay a $6,000 install for years.
- Ask about the written price before any work starts. We give you one on every job, so there are no surprises.
- Check your thermostat settings and seal drafty windows and doors. You’ll use the system less.
- Bundle a repair with a tune-up if both are due. It saves a second trip charge.
Every estimate from us is free, and a written price comes before any work begins. Call (984) 538-9003 to set one up. A live person answers, not a phone tree.
Repair or Replace? A Quick Decision Guide
This is the question homeowners ask us most, right after “how much?” Here’s a simple way to think about it.
- Check the age. If your system is under 10 years old and the repair is under $800, repair it. If it’s past 15 years, replacement starts making more sense.
- Add up recent repairs. If you’ve spent more than a third of the cost of a new system in the last two years, replacement is usually the smarter move.
- Look at efficiency. An older furnace may run at 80% efficiency, while a new one can hit 96%. That gap shows up on your energy bill every month.
- Get a written price for both. We’ll give you the repair number and the replacement number side by side, in writing, so you can decide without pressure.

FAQs – HVAC Cost
How much does an HVAC repair cost in Seattle?
Most HVAC repairs in Seattle run $175 to $765, with furnace repairs reaching $825 on the high end. A capacitor or igniter sits at the low end; a blower motor or control board sits higher. Call (984) 538-9003 for an exact quote. Estimates are free.
How much does a new AC cost in Seattle?
A full AC installation in Seattle runs $4,130 to $8,850, depending on system size, efficiency rating, and whether ductwork needs changes. Homes with existing ductwork land toward the lower end. Ask about Seattle City Light and Puget Sound Energy incentives to offset the total.
Is a tune-up worth the money?
Yes. At $95 to $235, a tune-up is the cheapest line item on this page and the one that prevents the expensive ones. It catches worn parts before they fail, often on the coldest night of the year. Book it in spring or fall to avoid the rush.
Is it cheaper to repair or replace my furnace?
If your furnace is under 10 years old and the repair is under $800, repair is usually cheaper. Past 15 years, or if you’ve spent more than a third of a new system’s cost in recent repairs, replacement tends to win. We’ll give you both numbers in writing so you can compare.
Can you come today?
In most cases, yes. We answer the phone 24 hours a day, 7 days a week, and same-day service is common for no-heat and no-cool calls. Every technician is background-checked through the Threshold Verified standard, and you’ll get their name and photo before they arrive. Call (984) 538-9003.
