AC Installation in Seattle, WA: What to Expect

Seattle has long been a heating-first market, but back-to-back heat waves in recent years have fundamentally shifted demand for AC installation Seattle. The city's historically mild summers rarely exceeded 76°F, but 2021's heat dome pushed temperatures well past 100°F for multiple consecutive days, accelerating adoption. Thirty-seven contractors serve this market with a 4.5-star average across 7,459 reviews, and ductless mini-splits have become the default choice for older Seattle homes without existing ductwork.

Window units provide the lowest entry point at $168-$784 installed. Ductless mini-splits (single zone) run $2,240-$8,960, making them viable for most Seattle home sizes. Central AC replacement using existing ducts, more common in newer construction, runs $3,920-$13,440. Washington has no statewide HVAC license — local permitting and municipal requirements apply, so confirm contractor credentials with the city.

Eco Electric, Plumbing, Heating and Air (4.9 stars) is consistently cited for fast scheduling and professional installation work. Brennan Heating, Air Conditioning, & Electric (4.6 stars) earns mention for workmanship quality across multiple review threads. Evergreen Home Heating and Energy (4.8 stars) is noted for prompt responses and technical expertise, particularly on heat pump and mini-split installations that have dominated recent demand.
