From a 1960s West Dublin original to a newer east-side home, Onzone handles whole-system HVAC installation across Dublin: furnace, AC, heat pump, or mini-split.
We install across Dublin, including West Dublin, Dublin Ranch, Emerald Glen, and the east side toward Wallis Ranch: furnace, AC, heat pump, and mini-split. Manual J sizing on every job, permits pulled, and a written proposal before anything is ordered.
Dublin splits between West Dublin, where 1960s homes are often on an aging first or second system due for full replacement, and the newer east side. Being 10 minutes away means fast site visits and quick follow-up.
Many Dublin homeowners replace both heating and cooling at once with a heat pump, one electric system that stacks BayREN, PG and E, and BAAQMD rebates. We map eligibility and compare it to a gas-and-AC swap 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, replacing them together is usually the better spend. We size them as a set and show both options in writing.
Yes. Older homes sometimes need a panel or duct upgrade, and we spell that out in the proposal along with the rebates. See heat pump installation.
