Quick answer
Both are licensed, established Puget Sound companies with an energy-forward pitch. Washington Energy Services has operated since 1957 — nearly seven decades — and pairs HVAC, plumbing, and electrical with windows, doors, siding, and insulation, citing 4.7★ across 9,000+ homeowner reviews (its published aggregate, July 2026). Eco, founded 2012, focuses purely on the three mechanical trades, carries 4.9★ across 2,300+ Google reviews, publishes installed pricing online, and is a PSE Trade Ally Network member.
- Washington Energy Services' 1957 founding is the longest track record in this comparison set — 69 years of continuous operation (per washingtonenergy.com).
- Their scope is wider than Eco's: beyond HVAC/plumbing/electrical they install windows, doors, siding, gutters, and insulation — envelope work Eco doesn't do.
- Eco's scope is deeper in the mechanical trades: sewer/drain work, commercial plumbing and electrical divisions, and smart panel/EV infrastructure.
- Published reviews, July 2026: WES cites 4.7★ from 9,000+ reviews aggregated across Google, Angi, and GuildQuality; Eco's Seattle Google profile shows 4.9★ across 2,300+.
- Both handle energy-efficiency projects; Eco is a PSE Trade Ally Network member and publishes its installed price ranges online.
Washington Energy Services is the elder statesman of Puget Sound home services — few companies anywhere run 69 years under one name. WES and Eco pitch a similar promise (a more efficient, more comfortable home) with different toolkits: WES adds the building envelope — windows, insulation, siding — while Eco goes deeper on the mechanical and electrical systems. Which one fits depends on which side of that line your project lives on.

Where Washington Energy Services stands out
Seven decades of continuity
A company operating since 1957 has survived every housing cycle, code change, and equipment generation since Eisenhower. If longevity is your proxy for stability — and it's not a bad one — WES has the longest record in this entire comparison series.
The building envelope under one roof
Windows, doors, siding, gutters, insulation, and home energy audits are things Eco simply doesn't do. If your efficiency project starts with single-pane windows or an under-insulated attic rather than the heating system, WES can carry the whole scope.
Review volume across platforms
WES publishes a 4.7★ average across more than 9,000 homeowner reviews aggregated from Google, Angi, and GuildQuality — a large, multi-platform body of feedback that's easy to spot-check yourself.
Where Eco fits best
Deeper mechanical-trades bench
Sewer and drain work (including commercial hydro jetting), commercial plumbing and electrical divisions, SPAN smart panels, and EV infrastructure — Eco's depth is in the systems behind the walls. If the project is pipes, panels, or heat pumps rather than windows, that depth matters.
Rebate-eligible heat pump installs
PSE's heat pump heating rebates require an REP or Trade Ally Network contractor (pse.com, July 2026). Eco is a PSE Trade Ally Network member and files the paperwork on qualifying projects — worth confirming with any bidder.
Published pricing and a 4.9★ average
Eco publishes typical installed ranges online and carries a 4.9★ Google average across 2,300+ reviews (July 2026). If you want numbers before the sales visit, they're already public.
How to choose between Eco and Washington Energy
Whichever way you lean, this is how we'd advise a friend to run the decision:
- Get written bids from both companies (and ideally a third) for any significant project — equipment model numbers, scope, permits, and warranty terms in writing, line by line.
- Verify any contractor's license, bond, and insurance at the WA L&I contractor lookup (secure.lni.wa.gov/verify) — both companies here are licensed Washington contractors.
- If your project involves a heat pump or heat pump water heater, ask each bidder how utility rebates will be handled and who files the paperwork. PSE requires a Recommended Energy Professional or Trade Ally Network contractor for its heat pump heating rebates (per pse.com, verified July 2026).
- Read recent reviews on Google for the specific service you need — a company can be excellent at one trade and thinner in another.
- Let the project pick the company: envelope-first efficiency (windows/insulation) points to WES; systems-first efficiency (heat pump, panel, water heater) points to Eco — and a genuinely whole-home plan might involve both.
- If a bid mixes envelope and mechanical scope, ask how each line item is priced — bundled scopes are where comparisons get hardest.

Common questions
Is Eco or Washington Energy Services better?
Both are licensed, established, energy-focused companies — the difference is scope. WES (since 1957) covers HVAC, plumbing, and electrical plus windows, doors, siding, and insulation; Eco (since 2012) goes deeper on the three mechanical trades with sewer/drain work, commercial divisions, published pricing, and PSE Trade Ally status. Match the company to where your project lives.
Who is cheaper, Eco or Washington Energy Services?
It depends on scope, and the two companies' offerings only partially overlap. For the overlapping work — heat pumps, water heaters, panels — Eco publishes typical installed ranges online so you can benchmark. Get written bids from both for your specific project; for envelope work, WES is the one of the two that does it at all.
Does Eco install windows or insulation like WES does?
No — Eco is a mechanical-trades company: electrical, plumbing, and heating & air. Windows, doors, siding, and insulation are Washington Energy Services' territory (and they've done it for decades). If your energy project starts with the envelope, WES belongs on your bid list; if it starts with the systems, that's Eco's specialty.
Which company handles utility rebates?
Both companies work in the rebate-heavy end of the market. Eco is a PSE Trade Ally Network member — required for PSE's heat pump heating rebates (pse.com, July 2026) — and handles paperwork on qualifying projects. WES emphasizes energy efficiency and audits; PSE publishes no public contractor directory, so ask them directly about network status for your utility.
