AfterFast, Reliable AC Installation Across Seattle
Most Seattle homes built before 2021 have no ductwork and no AC equipment at all, which means a standard central air retrofit is often impossible without major remodeling. A ductless mini split or cold-climate heat pump is usually the smartest path to cooling a house here, and a typical AC Installation in Seattle runs $4,130 to $8,850 depending on system size and configuration. Luis Serrano and the Meadowsweet Heating & Air crew know Seattle’s older housing stock, its steep lots, and its marine climate well enough to size a system for year-round use, not just August heat. Call (747) 966-3037 and a live person answers, 24 hours a day.
Why Meadowsweet Heating & Air Is Seattle’s Preferred AC Installation Company
We are part of the Cedarwell family of HVAC companies, founded in 2004, and every job we do carries the same three standards: a written price before any work starts, shoe covers and drop cloths inside the home, and a photo of the clean-up before the crew leaves. For families in Seattle with kids and pets, that last part matters as much as the equipment itself. We walk through the house before we unload anything, ask where the kids nap and which door the dog uses, and plan the work around those routines.
Our technicians are background-checked and uniformed, and they follow a code we call C.A.R.E.: Clean up like it’s their own home, Ask before moving anything, Respect the family’s time and quiet hours, and Explain the price before the work begins. That is a system, not a personality trait. When we install a mini split on a third-floor bedroom in Wallingford or route a line set through a crawlspace in Beacon Hill, the job ends with floors as clean as they were when we arrived. Every job is backed by the 365-Day Done Right Promise: if it’s not done right, we make it right, no runarounds and no fine print.
Dispatch and scheduling for Seattle are coordinated from our Seattle office, so when you call with a question about your install or a concern after the job is done, the person answering knows the area and can get a crew to you quickly.
Heat Pump Installation in Seattle
Heat Pump Installation in Seattle is often the right answer for a home that has never had cooling, because the same outdoor unit that cools in summer also heats in winter. That matters here: Seattle’s marine climate rarely drops to the temperatures where a heat pump loses efficiency, so a well-sized cold-climate heat pump can carry a home through most of the year and leave the existing furnace or boiler as backup. For rural properties east and southeast of Seattle with no natural gas line, the heat pump becomes the primary heat source, and the propane tank just sits there for the coldest nights. A full heat pump installation in the Seattle area typically lands between $4,130 and $8,850.
Ducted heat pump retrofits
Homes in Seattle that already have forced-air furnaces and ductwork can often switch to a ducted heat pump without touching the duct system. The indoor coil mounts on the existing furnace or air handler, and the outdoor condenser replaces the AC-only unit that may or may not be there. This is the cleanest path to year-round efficiency when the ducts are in good shape and the house has reasonable air sealing.
Load calculation before sizing
We do not size equipment by square footage. Seattle homes vary wildly: a shaded 1,200-square-foot bungalow in Ravenna needs a different unit than an exposed 1,200-square-foot ranch on a windswept hillside east of Lake Washington. We run a Manual J load calculation on every install, including rural properties with no wind shelter, because a condenser fighting wind-driven heat loss in January is a comfort problem and an efficiency problem all at once.
Ductless Mini Split Installation in Seattle
Ductless Mini Split Installation in Seattle is the defining HVAC job of this city, a direct result of how and when our homes were built. Early-20th-century Craftsman bungalows in Capitol Hill and Queen Anne often have radiators or old gravity furnaces and no return-air ductwork, so there is no place to attach a central AC system without cutting the house apart. A mini split solves that: a slim outdoor condenser, a small refrigerant line set, and wall-mounted indoor units. Single-zone mini split installation in the Seattle area runs $4,130 to $8,850.
Mini splits for homes with radiators
Older Capitol Hill and Queen Anne houses with steam or hot-water radiator systems have a pattern any local tech knows: no ductwork in the building envelope at all. Any cooling conversation automatically becomes a ductless job. The conversation about replacing the heating side is harder, because a forced-air furnace cannot simply swap in without a full duct build-out, which is a gut-renovation cost that usually kills the project. Mini splits give those homeowners cooling and shoulder-season heat without touching the radiators.
Whole-home ductless systems
For a Seattle house with no ducts and a real cooling need, a multi-zone mini split system can cover three or four rooms from one outdoor condenser. We run line sets through crawlspaces, attics, and along exterior walls with slim-duct concealment where possible. On steep hillside lots, the routing gets creative, and that is where a crew that has worked in Seattle for years earns its keep.
Trusted Brands We Service in Seattle
We install and service equipment from nine major manufacturers, and we regularly recommend three brands for Seattle’s conditions: Daikin and Mitsubishi-style low-temperature mini splits for ductless work, and Goodman or Rheem heat pumps for value-focused ducted retrofits. Because our Seattle office coordinates parts runs locally, a common capacitor, board, or blower motor is usually available same-day rather than shipped from a warehouse two states away. That shortens the gap between diagnosis and a working system when something goes wrong mid-summer.
Common AC Installation Problems We See in Seattle Homes
- No ductwork in older homes. Craftsman bungalows and early postwar ranches across Seattle were built with furnaces or radiators and no central air path. Any AC install here is automatically a mini split job unless the homeowner wants to open walls and ceilings for ductwork.
- Undersized equipment on exposed rural properties. A house with no wind shelter east of Seattle loses heat faster than the same house in a dense neighborhood. If the condenser is sized by square footage instead of a load calculation, it struggles on the rare cold snaps and may not keep up on a 95-degree day.
- Steep lots and crawlspace routing. Seattle’s topography means line sets and drain lines often run through tight crawlspaces, under hillside foundations, and across split-level transitions. A routing plan that works on flat ground does not work on a 30-degree slope in West Seattle.
- Propane systems quoted as natural gas. Rural addresses outside Seattle often have no gas main, and a quote built around a natural gas furnace is useless. The project has to restart as a propane or heat-pump design, which wastes time and money.
Pricing for AC Installation in Seattle, WA
Here is what a Seattle homeowner should expect to pay for common AC installation and related work:
| Service | Cost Range |
|---|---|
| Heat pump installation (ducted or ductless, primary system) | $4,130-$8,850 |
| Ductless mini split installation (single zone) | $4,130-$8,850 |
| Capacitor replacement | $175-$765 |
| Annual tune-up / thermostat calibration | $95-$235 |
What moves a Seattle install toward the top of that range: multi-zone systems, difficult line-set routing on steep lots, electrical panel upgrades, and cold-climate heat pump models sized for year-round heat on rural properties with no gas.

FAQs About AC Installation in Seattle
Yes, and in most cases the best answer is a cold-climate heat pump sized as the primary heating and cooling system, with the existing propane tank kept as backup for the coldest nights. We quote these jobs with the no-gas constraint built in from the first visit, so you do not end up with a gas furnace design that cannot be connected. Call (747) 966-3037 and we will come out and assess your property.
Because most Seattle homes built before 2021 have no ductwork, and retrofitting ducts into a 1920s Craftsman or 1950s ranch means opening walls and ceilings at a cost that usually kills the project. A mini split needs only a small outdoor unit, a narrow line set, and wall-mounted indoor heads, which gets cooling into an older home without touching the radiators or the original layout.
Yes. We recently ran a load calculation for a customer on a wooded lot off Southeast 208th Street in unincorporated King County east of Seattle whose propane furnace had quit and who had a detached 600-square-foot shop to condition. We sized a cold-climate heat pump as the primary system for the house and added a ductless mini split for the shop, setting refrigerant charge and verifying static pressure on the new air handler before we left. Now the propane tank only backs up the backup heat, and both buildings cool through the summer heat spikes.
Yes, and it matters more on a rural Seattle property than in a dense neighborhood. An exposed home with no wind shelter loses heat faster in winter and gains it faster in a heat event, so a load calculation is the only honest way to size equipment. Square-footage rules of thumb leave those homes underheated in January and uncomfortable in August.
A ducted or ductless heat pump installation as a primary system in the Seattle area runs $4,130 to $8,850, and a single-zone mini split sits in the same range. Capacitor replacement runs $175 to $765, and an annual tune-up with thermostat calibration is $95 to $235. We give every customer a written fixed price before any work starts, and the estimate visit is free. Call (747) 966-3037 to schedule one.
