Editorial Review
More than 50 years in Seattle and over a thousand reviews at 4.8 give Evergreen one of the deepest local track records on this list. Its heat pump and rebate experience is the main reason to call, though a few reviewers found its quotes high, so get the price itemized.
Best for: Homeowners switching from oil or gas to a heat pump

Coverage is as the business describes it, cross-checked against where its recent documented work is. A company will often travel beyond the areas listed here for a large job and decline a small one at the same distance, so confirm your address before scheduling.
Evergreen Home Heating and Energy has served Seattle homeowners since 1975 and is still family-owned and locally run. The shop sits on South Kenyon Street in Georgetown, a short drive from most of the city, and the company holds 1,008 Google reviews at a 4.8 average as of September 23, 2026. Only Brennan has more reviews among the companies here that work mainly on heating and cooling.
Much of Evergreen's work today is heat pumps. It is an authorized Mitsubishi Electric dealer and installer, and its site explains the Seattle City Light Clean Heat rebate for homes moving off oil heat, along with Energy Smart Eastside rebates for customers across the lake. It also repairs and replaces gas furnaces, central air, ductless systems, water heaters and thermostats, and it runs natural gas piping and electrical work in-house. The Google listing shows air duct cleaning as well.
Reviewers name technicians often. Tim is praised for returning on his day off with a part in early July, and another customer called his walkthrough of a four-unit system the tutorial they never got at install. John gets credit for explaining furnace options honestly and steering a customer toward the lower-cost choice, and Aaron and Erin are named for quick, accurate diagnosis. Victoria in scheduling and Brandon, the service manager, come up in longer-term customer reviews. The negative reviews are about price. Two recent one-star reviewers felt quotes for replacement or a thermostat were far higher than they expected, and one said a callback from the service manager did not come.
The company lists a free estimate on new systems, 24/7 service, 18 months of special financing with no minimum purchase on approved credit, and a Home Comfort Club with priority scheduling and two tune-ups a year. Its contractor license number, EVERGHH910JO, is printed on the site and can be checked on the Washington L&I contractor lookup.
Evergreen fits homeowners in older Seattle houses who want to retire an oil tank or aging furnace and would like one company to handle the heat pump, the electrical and the rebate paperwork. It is a weaker fit for someone who only wants the cheapest repair. Before signing, ask for a written, itemized quote and a second option if a repair is possible instead of replacement.
Company history, ownership and capability details on this page are provided by the business and reviewed by our editors for plausibility and consistency. They are not the same as the credentials block, where each item carries its own verification status and source.
Verified means we checked the credential against the authority that issues it and recorded the date. Reported means the business told us and we could not independently confirm it. We publish both, labelled, rather than dropping what we could not check.
We show each source separately rather than blending them into a single score, because they measure different things.

Seattle. Coverage is as the business describes it, cross-checked against where its recent documented work is. Confirm your address before scheduling, particularly at the edge of a service area.
Yes, the company lists emergency availability. Response time depends on demand, and after a storm every company in the market is stretched.
Covered repairs and installs are backed by manufacturer warranties; the company does not publish its own labor warranty terms, so ask for them in writing.. There are usually two warranties on a job: the manufacturer covers materials, the contractor covers workmanship. Get both in writing and check whether the workmanship coverage transfers if you sell.
Credentials come from issuing authorities, ratings from the company's Google Business Profile with the date we read them, and the editorial take from our own review of estimates, warranty documents and public feedback. Anything the business told us is labelled as reported.
A business can subscribe to manage its own listing details, and it can buy a labelled sponsored placement. Neither changes a ranking position or the editorial assessment on this page.
