San Jose runs hot, and a lot of its homes still have their first system. Onzone handles AC installation and replacement across the city, sized to real load.
We install across San Jose, including Willow Glen, Cambrian, Almaden Valley, Berryessa, Evergreen, and downtown. Manual J load calculation on every job, permits pulled, and a written line-item 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 install replacements and new ducted cooling across the city.
San Jose is hotter and drier than the East Bay, and Almaden and Evergreen run hotter than downtown. We size by Manual J to the specific neighborhood and house so the system holds up through a long cooling season.
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, permit and inspection are included and handled by us in San Jose.
If it is decades old and failing, usually yes. We run a fresh load calc instead of matching the old system, which was often sized by rule of thumb.
It can. Almaden and Evergreen see hotter afternoons than downtown, and the load calc accounts for that so you are not under-cooled on peak days.
