HVAC repair in Seattle, the local picture
We handle heating repair, air conditioning repair, and heat pump work for Seattle homes, and you can call us to get on the schedule. Seattle housing runs from 1920s Craftsman bungalows in Ballard and Wallingford to 1960s split-levels and newer townhomes with tight mechanical closets, and each one heats and cools differently. A lot of the older stock never had ducts sized for cooling, so we spend real time on ductless heat pumps and on making existing systems move air where people actually sleep. Summers here are short but the July and August stretch gets hot in an upstairs bedroom with no shade, and smoke season means filtration and IAQ come up in most conversations. Winter is wet more than frigid, which is what causes heat pump defrost trouble: the outdoor coil ices, the reversing valve cycles, and the house feels lukewarm. If your system is short cycling, blowing cool air on heat, or just quit, tell us what it is doing and we will come look.
Much of Seattle went up between the 1900s and the postwar years, so bungalows, Craftsman homes and midcentury ramblers dominate, often with balloon framing, thin wall cavities and unfinished basements or crawlspaces. Many were built without cooling at all, which is why ductless heat pumps and retrofit ductwork come up constantly on older blocks.
I-5, I-90, SR-99 and Aurora Ave N are the routes we cover from here.

How soon can you get to a Seattle home?
Call us with your address and what the system is doing, and we will give you the next available window rather than a vague promise. No-heat and no-cool calls get priority, and during a hot stretch in August or the first cold snap we book out faster, so calling early in the day helps. If you want to try two safe things first, check the thermostat batteries and settings and look for a tripped breaker.
Do you work outside Seattle city limits?
Yes. We serve homes across the Puget Sound area including Shoreline, Edmonds, Lynnwood, Bellevue, Kirkland, Redmond, Renton, Burien, and Mercer Island, plus locations throughout Washington and Oregon. If you are not sure whether your street falls in our range, call and ask. We will tell you straight instead of sending you a technician who cannot make the drive.
What does a repair visit cost?
We put the whole number in writing before touching the machine, so the invoice never surprises you.
Which brands do you service?
All the majors: Carrier, Trane, Lennox, Goodman, Rheem, York and the rest, gas or electric, independently of any manufacturer.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form. Describe the noise, the smell, the temperature, and when it started. That detail helps us bring the right parts and gives you an honest idea of the visit ahead.
- Step 2
We diagnose on site
A technician checks the thermostat, airflow, electrical connections, refrigerant behaviour and the outdoor unit. We tell you what failed and why, in plain language, before anyone reaches for a part or a price.
- Step 3
You choose the repair
We lay out the fix, any parts on order, and what happens if you wait. Once you agree, we do the work and confirm the system holds temperature before we pack up and leave.

Why homeowners call us
- Heat pumps are our normalIn this region heat pumps outnumber furnaces, so defrost boards, reversing valves and short cycling in wet weather are everyday work for us. We know how these systems behave in a cold December rain, not just on a test bench.
- Wet winter defrost problemsIce on the outdoor coil, a unit that runs and runs without warming the house, puddles that refreeze under the pad. We trace whether it is a sensor, a stuck valve, drainage, or airflow, then fix the actual cause.
- Filtration after smoke seasonWildfire smoke turned indoor air quality into a real conversation here. We look at filter fit, return sizing and IAQ options that your blower can actually push air through, rather than choking the system with the wrong media.
- We explain before we chargeYou get the diagnosis, the options and the trade-offs before work starts. If a repair is not worth it on an old system, we say so. No pressure, no jargon dumped on you at the door.

- Straight answersNot worth fixing? We say that out loud, and often it saves you the visit fee.
