Hayward is full of postwar homes on their original systems. Onzone handles whole-system HVAC installation across the flatlands and up into the hills.
We install across Hayward, including downtown, the flatlands, the Hayward Hills, and South Hayward: furnace, AC, heat pump, and mini-split. Manual J sizing on every job, permits pulled, and a written proposal before anything is ordered.
Hayward is postwar tract country, with whole neighborhoods built in the 1950s, so many homes are on their oldest working furnace and AC. We do whole-system replacements and add heating and cooling where there was none, flatlands to hillside.
The mild, fog-cooled Hayward climate is an easy match for a heat pump, which covers heating and cooling on one electric system and earns BayREN, PG and E, and BAAQMD rebates. We confirm rebate eligibility and size it to the home before you commit.
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 both are original and old, together is usually the better spend. We size them as a set and quote both paths.
Yes. Postwar homes often need duct evaluation and sometimes an electrical upgrade, and we quote all of it in writing after the load calc.
In the mild Hayward climate, often yes, and the rebates are real. See heat pump installation.
