A lot of Danville homes went in during the 1970s and 80s and are due for their first real system replacement. Onzone handles that AC installation, sized right and permitted.
We install across Danville, including downtown, Blackhawk, the Camino Tassajara corridor, and Alamo just to the north. Manual J load calculation on every job, permits pulled, and a written line-item proposal before anything is ordered.
A big share of Danville housing dates to the 1970s and 80s, exactly the age where an original system is worth replacing rather than repairing again. We install across downtown, Blackhawk, and out toward Alamo.
Danville summers are long and dry with hot afternoons, so cooling load is real even with the cool evenings. We size by Manual J so the system carries the hot part of the day without short-cycling at night.
You get a line-item proposal covering equipment, labor, permit, and disposal before anything is ordered. We pull the permit and handle the city inspection, so the price you approve is the price you pay.
Yes, both are included and scheduled by us. You approve the proposal, we deal with the town.
Yes. We install in gated communities including Blackhawk, and nothing about the process changes.
If it is original and past its service life, replacement is usually the right call. We size the new system fresh instead of matching a decades-old spec.
If it is salvageable, see AC repair in Danville. We recommend replacement only when the repair no longer pays off.
