From 1950s Glenmoor-era homes to newer east-side builds, Onzone handles whole-system HVAC installation across Fremont: furnace, AC, heat pump, and mini-split.
We install across Fremont, including Mission San Jose, Centerville, Niles, Warm Springs, and Ardenwood: furnace, AC, heat pump, and mini-split. Manual J sizing on every job, permits pulled, and a written proposal before anything is ordered.
Fremont grew out of five older towns, so system ages jump block to block, from 1950s and 60s Glenmoor-era tracts on original equipment to newer construction. We do whole-system replacements and heat pump conversions across all of them.
Because Fremont system ages jump block to block, we start with a load calc, then show where a heat pump fits: one electric system for heating and cooling, plus BayREN, PG and E, and BAAQMD rebates a gas-and-AC pair cannot claim. Eligibility goes on the quote.
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, yes, matching them as a system is usually the better spend. We quote both paths.
Yes. Older homes sometimes need duct or panel work, spelled out in the proposal with the rebates. See heat pump installation.
