Generator Installation in Union City, CA

Backup power only helps if the switching works when nobody is home. Automatic transfer switches, interlocks and battery systems all need to isolate from the utility cleanly, and that is where a bad install becomes dangerous for line crews as well as for you.

Call (833) 652-8933 and describe what is happening. If it is a same-day job we will book it today, and if it needs a site visit to quote properly we will tell you that too.

Situations we see in Union City

Whole house or essential circuits

A critical-load subpanel is far cheaper than whole-house coverage and keeps heat, refrigeration and internet running. We price both.

Not sure what size to buy

We meter and calculate rather than estimate. Most Union City homes land between 14kW and 26kW depending on AC, well pumps and electric ranges.

Existing generator won't start on outage

Usually the transfer switch, the battery or the exercise routine, not the engine. We diagnose the switching first.

Extension cords through a window

Common and genuinely dangerous. An inlet box and interlock costs a fraction of a standby unit and ends the practice.

Reviews from Alameda County

Warehouse high bay retrofit to LED. Did it over a weekend so we never stopped shipping, and the place is twice as bright.

Greg L.Warehouse lighting · Union City

Bought a 1948 house with cloth wiring. They phased the rewire so we always had power in half the house, and gave us paperwork our insurer accepted.

Sofia M.Rewiring · Union City

We needed a 200 amp panel before our EV charger install. They did the load calculation, pulled the permit, and had the whole thing done and inspected in a week.

Generator Installation in Union City — questions

Will the generator start automatically when the power goes out?

With an automatic transfer switch, yes, typically within 10 to 30 seconds. With a manual switch or interlock you start it and flip the switch yourself, which is a cheaper install.

Do I need a permit to install a generator in Union City?

Yes, and often a gas permit too. We handle the electrical permit and inspection and coordinate with your gas contractor or plumber.

How often does a standby generator need service?

An annual service plus the weekly self-exercise cycle. The exercise routine matters more than owners expect, because it is what catches a dead battery before an outage does.

How much does a whole house generator cost in Union City?

The unit is roughly half the project. The rest is the transfer switch, pad, gas line, electrical and permit. Sizing drives everything, so call (833) 652-8933 and we will run a load study before quoting.

Can you install a battery instead of a generator in Union City?

Yes. Battery backup runs silent, needs no fuel and pairs with solar, but has a fixed energy budget. For multi-day PSPS events a generator still wins on runtime.
