AfterHow Much Does HVAC Cost in Seattle?
Most HVAC work in Seattle falls between $95 and $8,850, depending on whether you’re booking a tune-up or replacing a whole system. A standard repair runs $175 – $825, an annual tune-up is $95 – $235, and full AC installation lands between $4,130 and $8,850. Those are the ranges we work from every day, and they hold whether you’re in Ballard, West Seattle, or out past Bellevue.
Dalton Heating & Air has been servicing homes since 2003 as a Garrison Partners company, and one thing hasn’t changed: you get the price in writing before any work starts. No drift at the door, no numbers that shift once the truck is in your driveway. Here’s what HVAC actually costs in Seattle in 2026, and what moves those numbers up or down.
HVAC Cost Breakdown (2026)
These are the Seattle-market ranges we quote, and they’re consistent across every location in our network. Use them as your baseline when you’re comparing estimates.
| Service | Typical Seattle Range | What It Covers |
|---|---|---|
| Annual tune-up | $95 – $235 | Cleaning, inspection, filter change, safety check |
| Furnace repair | $175 – $825 | Parts and labor for most residential fixes |
| AC repair | $175 – $765 | Parts and labor for most residential fixes |
| AC installation | $4,130 – $8,850 | New condenser, lines, and labor |
What pushes a job toward the top of the range? Parts, mostly. A capacitor or a control board is a quick, inexpensive fix. A failed compressor or a blower motor pulls the price up because the part costs more and the labor takes longer. System size matters too: a small condo unit in Capitol Hill sits at the low end, while a 3,000-square-foot Craftsman in Magnolia with a two-zone setup sits higher. Age plays a role as well. A 20-year-old furnace in Rainier Valley may need a part that has to be ordered, which adds a day and a bit of cost.
If you want the full service menu before you call, our home page lays out what we handle. For the specific repair you’re facing, it helps to know the market rate going in so nobody can tell you a capacitor costs $600.
What Affects HVAC Pricing in Seattle
- System age and efficiency rating. Older furnaces and AC units in Seattle’s pre-1980s housing stock often need discontinued parts or a full replacement. A high-efficiency model with a variable-speed blower costs more to service than a basic single-stage unit because there are more components to diagnose.
- Seattle’s climate and how we actually run our systems. We heat more than we cool here. That means furnace repairs outnumber AC repairs on our trucks most of the year, and the wear pattern is different from a Phoenix or Dallas market. A furnace in a drafty Wallingford bungalow works harder through a wet, 40-degree January than one in a new Ballard townhouse with tight envelope construction.
- Heat pump versus traditional system. Heat pumps are common in Seattle, and they cost more to diagnose because the repair can live on the refrigerant side or the electrical side. A refrigerant recharge, which means topping off the cooling fluid your system needs to hit set temperature, adds both the fluid and the labor to find the leak.
- Access and location in the home. An attic furnace that requires crawling through a tight access panel takes longer than one in a garage. Homes in West Seattle with steep lots sometimes need equipment staged differently, and that time shows up in the price.
- Season and scheduling. The first cold snap in November fills the calendar, and emergency calls after hours cost more than a scheduled visit during the day. Booking a tune-up in September or a repair in March keeps you ahead of the rush and off the emergency rate.
- Parts availability and brand. We’re factory-trained to service nine major residential brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. A part that’s in stock locally means a same-day fix. A discontinued board for an older unit means ordering, and that’s a real cost difference.
How to Save on HVAC
The single biggest lever is maintenance. A $95 – $235 tune-up once a year catches the worn capacitor or the clogged drain line before it becomes a $400 repair in February. Most of the emergency calls we run in Seattle are things a fall inspection would have flagged.
Here’s how to keep your costs down without cutting corners:
- Book your tune-up before the season turns. Schedule heating service in early fall and cooling service in spring. You’ll get a non-emergency rate and a technician who isn’t sprinting between calls.
- Change your filter on schedule. A dirty filter makes the blower work harder and shortens the life of the motor. It’s the cheapest insurance against a breakdown.
- Ask for a repair-or-replace assessment in writing. If your system is past 15 years and the repair is more than 30% of a new install, replacement often makes more sense. Get the numbers before you decide.
- Get the estimate before the work begins. Every Dalton job includes a written price before we start, so you never face a surprise at the door. That’s The Garrison Standard, and it’s not optional.
- Compare full-system efficiency when you replace. A high-efficiency unit costs more up front but cuts your heating bill through Seattle’s long damp season. On a 2,000-square-foot home, the difference pays back over several years.

FAQs – HVAC Cost
How much does a furnace repair cost in Seattle?
Most furnace repairs in Seattle run $175 – $825, with the price driven by the part and how long the diagnosis takes. A capacitor or ignitor sits at the low end; a blower motor or control board sits higher. Every repair we do comes with a written price before we start and a full-year written guarantee. Call (361) 306-9515 for an exact quote on your furnace.
How much does AC installation cost in Seattle?
AC installation in Seattle runs $4,130 – $8,850 depending on system size, efficiency rating, and whether ductwork needs modification. A small condo unit lands near the bottom; a large home with a multi-zone setup lands near the top. We’ll give you a written quote after we size the system to your home. Call (361) 306-9515 to schedule an assessment.
Is it cheaper to repair or replace my HVAC system in Seattle?
Repair is cheaper in the short run when your system is under 12 years old and the fix costs less than 30% of a new install. Past 15 years, or when the repair is a compressor or heat exchanger, replacement usually wins on total cost. We put both numbers in writing so you can decide. Call (361) 306-9515 for a free estimate on either path.
Can you come today for an HVAC repair?
Yes, in most cases we can reach Seattle-area homes the same day, and our phones are answered by a live person 24 hours a day. Emergency calls after hours carry a higher rate than a scheduled daytime visit. If your heat is out or your AC has quit, call (361) 306-9515 and we’ll tell you exactly when a technician will arrive.
How much does an HVAC tune-up cost in Seattle?
A tune-up in Seattle runs $95 – $235 and covers cleaning, inspection, a filter change, and a safety check on the system. It’s the cheapest way to catch small problems before they turn into $400 repairs. If the tune-up turns up a needed fix, the price is in writing before we touch anything. Call (361) 306-9515 to book one.
