HVAC in Sunnyvale.
The same trusted HVAC expertise that's served the Bay Area since 1986 — now on your street in Sunnyvale. Heritage District bungalows and Downtown Sunnyvale new construction.
Heritage District, Ortega Park, Cherry Chase.
The Heritage District keeps early-1900s farmhouses and bungalows from Sunnyvale's orchard era; Cherry Chase and Ortega Park are 1950s–60s ranch tracts, many with Eichler-adjacent flat-roof designs and no attic to run ducts through.
Flat roofs and low-slope construction rule out the easy answer, so we design around them — ductless multi-zone systems, compact ducted heat pumps in reworked closets, and exterior line routing done neatly instead of stapled on. In the older bungalows it's duct sealing, added returns, and heat pump conversion off aging gas furnaces.
The Downtown Sunnyvale and Peery Park developments — planning through execution.
New Sunnyvale homes and townhomes get the full treatment from plans to punch list: Manual J, duct design in conditioned space, zoning by floor, all-electric heat pump systems sized to the panel, and commissioning with real measurements before handoff.

AC repair in Sunnyvale
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 Sunnyvale. Refrigerant leaks, failed capacitors and compressors, condensate problems, and the airflow restrictions that cause most "weak AC" calls.
Furnace repair in Sunnyvale
Gas furnaces, wall furnaces, and the floor furnaces still working in plenty of Heritage District 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 Sunnyvale
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.
