A lot of San Jose homes still run their original furnace and AC. Onzone handles whole-system HVAC installation across the city: furnace, AC, heat pump, and mini-split.
We install across San Jose, including Willow Glen, Cambrian, Almaden Valley, Berryessa, Evergreen, and downtown: furnace, AC, heat pump, and mini-split. Manual J sizing on every job, permits pulled, and a written proposal before anything is ordered.
Big parts of San Jose were built in the 1950s and 60s, and neighborhoods like Cambrian and Willow Glen are full of homes on aging original systems. We do whole-system replacements and heat pump conversions across the city.
Almaden and Evergreen run hotter than downtown, so we size the heat pump to your neighborhood, not the city average. It covers heating and cooling on one electric system and earns BayREN, PG and E, and BAAQMD rebates, and we map eligibility before you decide.
You get a line-item proposal covering equipment, labor, permit, and disposal before anything is ordered. We pull the permit, handle the city inspection, and map any rebate you qualify for, so the price you approve is the price you pay.
If the furnace and AC are both old, together is usually the smarter spend. We size them as a matched set and quote both options.
For most homes, yes, with real rebates and a long cooling season it handles well. See heat pump installation.
