HVAC in Sonoma.

The same trusted HVAC expertise that's served the Bay Area since 1986 — now on your street in Sonoma. Sonoma Plaza adobes and Schellville-area new builds, with wildfire-season air quality in mind.

A view of Sonoma, California
Retrofits in Sonoma's older neighborhoods

Sonoma Plaza, East Napa Street corridor, Boyes Hot Springs.

Sonoma Plaza and the East Napa Street corridor hold 19th-century adobes, Victorians, and early ranch homes; Boyes Hot Springs adds mid-century cottages. Many were built before central air, and wildfire smoke has made filtration a real priority.

We preserve historic character with ductless and small-duct systems, convert old wall and floor furnaces to heat pumps, and design filtration around wildfire season. Older homes get combustion safety checks and careful routing so original ceilings and plaster stay intact.

New builds in Sonoma

Schellville and the Sonoma Highway corridor new construction — planning through execution.

New Sonoma homes and winery-adjacent builds get planning-stage mechanical design: load calcs that account for large openings and indoor-outdoor living, quiet heat pump systems, MERV-13-capable filtration and fresh-air ventilation, and commissioning with airflow documented.

What we handle in Sonoma

AC repair in Sonoma

Warm room, short cycling, or a system that runs all afternoon without catching up — we diagnose and repair air conditioners and heat pumps of any brand in Sonoma. Refrigerant leaks, failed capacitors and compressors, condensate problems, and the airflow restrictions that cause most "weak AC" calls.

Furnace repair in Sonoma

Gas furnaces, wall furnaces, and the floor furnaces still working in plenty of Sonoma Plaza homes. We handle ignition and flame-sensor faults, blower and control board failures, heat exchanger inspection, and honest replace-or-repair advice when a unit is past its service life.

Heat pump installation in Sonoma

Gas-to-electric conversions and high-efficiency heat pump installs, sized with a Manual J load calculation rather than the old nameplate. Duct design, permits, Title 24 duct-leakage testing, rebate paperwork, and commissioning with measured airflow before we hand over the thermostat.
