Dependable heat for Howell Mountain winters.

Winter matters more in Angwin. Mountain nights run colder and longer than the valley floor, and heat up here isn’t a comfort feature — it’s the thing the house runs on. We keep Angwin’s furnaces and heat pumps running, and we install replacements built for the elevation.

Heating work worth the drive.

When the heat fails on the mountain, we prioritize the trip, diagnose fully, and quote one price before work begins. Combustion and safety checks come standard. If the honest fix is small, that’s the recommendation — no commissions, no upsell theater.

Replacements get engineered for mountain winters: proper load math, equipment that handles sustained cold snaps, and installation to Bryant Factory Authorized standards. The quote holds regardless of the elevation gain.

Reliable, all the way up the mountain.
