HVAC in Pleasanton.

The same trusted HVAC expertise that's served the Bay Area since 1986 — now on your street in Pleasanton. Downtown Pleasanton retrofits and Ruby Hill-area new installs, planned end to end.

Retrofits in Pleasanton's older neighborhoods

Downtown Pleasanton, Vintage Hills, Val Vista.

Main Street's surrounding blocks hold Victorians and early-1900s homes on small lots; Vintage Hills and Val Vista are 1960s–70s ranch and two-story tracts with aging ducts and original returns.

Downtown Pleasanton homes need careful, low-impact work — ductless or high-velocity systems where a conventional retrofit would mean tearing out original ceilings. In the tract neighborhoods it's duct testing and rebuild, added return air, and right-sized heat pump replacement that finally makes the upstairs livable in August.

New builds in Pleasanton

The Ruby Hill and East Pleasanton new construction — planning through execution.

On new Pleasanton builds we're involved from the plan set forward: load calculations, duct design coordinated with framing, multi-zone systems for larger footprints, high-MERV filtration, and a commissioning report at handoff.

What we handle in Pleasanton

AC repair in Pleasanton

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 Pleasanton. Refrigerant leaks, failed capacitors and compressors, condensate problems, and the airflow restrictions that cause most "weak AC" calls.

Furnace repair in Pleasanton

Gas furnaces, wall furnaces, and the floor furnaces still working in plenty of Downtown Pleasanton 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 Pleasanton

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.
