Backup generator installation in San Jose, CA
A generator is only as good as its transfer switch and its sizing. Undersized units in Santa Clara County homes trip on the first AC start; oversized ones cost more to buy and run. We measure what you need to keep running, then specify from there.

Generator Installation across San Jose
We cover every part of San Jose — Rose Garden, Japantown, Berryessa and Willow Glen included — along with the neighboring communities of Milpitas and Santa Clara.
San Jose sits in Santa Clara County, and the electrical work here reflects that mix: older housing stock that needs grounding, capacity and device upgrades, alongside newer construction that simply needs more circuits than it was built with. Crews route through Silicon Valley daily, so travel time to a call in San Jose is short.

|---|---|
| Transfer switch scope | Whole-panel switching costs more than an essential-circuits sub panel. |

Recent San Jose feedback
Generator sized properly, transfer switch installed, and they tested it under load. Ran the whole house through the last shutoff without us touching anything.
Greg H.San Jose, CAOld fuse box gone, 200 amp service in, inspection passed the first time. Clear communication the whole way through.
Bethany W.San Jose, CAOur restaurant cannot close, so they did the panel work overnight. Walked in the next morning to everything working and the floor cleaner than we left it.
Nadia F.San Jose, CAGenerator Installation in San Jose — questions we get asked
What size generator do I need in San Jose?
It depends on whether you want the whole house or essential circuits. Many San Jose homes are well served by a mid-size air-cooled unit with load management; all-electric homes with heat pumps and EVs need more. We run the calculation before quoting.
Do generators need permits in San Jose?
Standby generator installations involve electrical and often mechanical permits in California, plus setback and noise rules that vary by Santa Clara County jurisdiction. We handle the electrical permitting and flag local requirements early.
How often does a standby generator need service?
Plan on annual service and a monthly self-test, which most controllers run automatically. Oil, filters and battery are the usual wear items.
Can you install a transfer switch for a generator I already own?
Yes. For portable units, an interlock kit or a manual transfer switch is usually the right answer, and it is far cheaper than a standby install.
Will a generator run my EV charger?
Technically yes, practically it is a poor use of fuel. Most owners exclude EV charging from the backed-up loads and keep the capacity for HVAC and refrigeration.
