Hold every HVAC company to this list — including us
Five things worth demanding from anyone who touches your home's comfort, and how we answer each one with facts you can check.
Demand #1
Know who actually owns the company
Much of the home-services industry has consolidated under national chains and private-equity groups — often keeping the local name on the trucks. Glendale is owned by four people you can name — Sarah Turner, Chad Fulton, Greg Hoefer, and Randy Hoefer — carrying on a family business that's been at the same work since 1938. When ownership answers for the work, the work gets answered for.
Demand #2
Longevity you can verify
Eighty-seven years serving Greater Seattle isn't a slogan; it's our service history — from oil conversions in pre-war Craftsmans to heat pumps in brand-new DADUs. Companies survive that long in one market exactly one way: by being worth calling back.
Demand #3
Real capability, not just installers
We run our own sheet metal fabrication shop — increasingly rare in residential HVAC. Custom plenums, transitions, and replacement duct runs for the odd geometries of older Seattle homes get made, not improvised. It's the difference between fitting equipment to your house and bending your house around catalog parts.
Demand #4
Accountability in writing
WA license GLENDHA053Q2. A 60-day workmanship guarantee on repairs. Registered manufacturer warranties handled for you, with the maintenance records that keep them enforceable. And third-party checkmarks we didn't write ourselves: Lennox Centurion Award (2026), Angi Super Service Award, Nextdoor Neighborhood Favorite, BBB accreditation.
Demand #5
Honesty you can test before you hire
Read our pricing pages: every number is a sourced market range with the source named — never bait. Our maintenance plans print their math. Our guides tell you when NOT to buy things. And our second opinion on replacement quotes is free precisely because scrutiny is a test we like taking.

Fair questions
Is Glendale really still family-owned?
Yes — four named owners (Sarah Turner, Chad Fulton, Greg Hoefer, and Randy Hoefer) continuing a business founded in 1938, based at the same Des Moines Memorial Drive shop in Burien. No national chain, no holding company.
What does the in-house sheet metal shop actually mean for me?
Custom ductwork without subcontracting or improvisation: plenums, transitions, and replacement runs fabricated to fit your house — especially valuable in Seattle's older homes where catalog parts rarely fit the basement that exists.
What's the 60-day workmanship guarantee?
If a repair we performed fails within 60 days, we make it right — our layer of accountability, separate from manufacturer parts warranties. It's survived since 1938 because standing behind work is cheaper than arguing about it.
Which brands do you install, and why several?
Lennox (independent dealer), Daikin (authorized dealer), and Mitsubishi Electric as a Mitsubishi Diamond Dealer — because Seattle's housing stock is too varied for one catalog. The estimate picks the machine that fits your house, not a franchise quota.
