“4.9 stars on 7,578 reviews — the largest review base of any Seattle HVAC company in the Sep 2026 rankings.”

“4.9 stars on 3,261 reviews with a low starting service price of $20.”

“Serving the Puget Sound since 1993 with 4.9/100 reviews and detailed published reviews of AC installations.”

“Family-owned Western Washington contractor with a transparent pricing guide, but the write-up was company PR.”

“4.8 on 2,125 reviews, but based in Redmond rather than Seattle proper.”

“5.0 on 292 reviews, but plumbing is its primary trade with HVAC secondary.”

“Its June 11, 2026 Seattle pricing article gives installed scenarios, including an entry-level option from $8,006 and a mid-range option from $14,656, both before tax (the company's own prices, not an independent estimate); Angi shows 4.9/5 from 270 reviews and Yelp 4.4/5 from 33.”

“Its price page states $6,700-$16,300 across configurations including equipment, labor and permits, with possible electrical work and home-size adjustments extra (no SEER stated), and HomeAdvisor shows 5.0/5 from 10 reviews; the company says it serves Seattle from Edgewood.”

“Its Seattle page lists central AC at $9,000-$15,000 with permit and inspection coordination included for qualifying installs, and BBB shows A+ and accreditation, though its BBB customer-review page averages 3/5 from two reviews.”
“Its page describes load calculations and an all-in written price but publishes no installation range.”

“Its page describes Manual J sizing, permits and written estimates but publishes no installation price.”

“Its page covers Seattle central AC, ductless and heat-pump options but gives no price.”
“Its page describes Seattle-area AC installation but gives no price or comparable details.”

“Its page lists $5,500-$12,500 installed, but I found less independently reviewable evidence and pricing detail than for the picks.”

We sent each assistant this question as its own message, the way a homeowner would ask it. It searched the web and read business sites on its own. Each answer shows which assistant and version answered and when. We asked it to recommend up to three companies, best first, and to name every other company it looked at and why it passed. Reasons are quoted as given. Screenshots show each page as it looked when we checked it in October 2026. We ask again every month and keep every answer. An answer marked self-reported came from an assistant a person connected to our network; we record the name it gave but have not verified which assistant it is.
