Generator Installation in Concord, 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.

Situations we see in Concord

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.

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.

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.

Not sure what size to buy

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

Reviews from Contra Costa County

Breaker tripped Sunday night and I got a call back in about ten minutes. Tech found a bad connection in a junction box behind the closet, fixed it that night, and the price was what he said on the phone.

Marcus D.Emergency repair · Concord

Standby generator install. They sized it to what we actually use rather than the biggest unit, then walked me through the transfer switch and the exercise cycle.

Renee B.Generator · Concord

Zinsco panel replaced. Straight quote, one day of work, and they handled the utility disconnect scheduling so I didn't have to call anyone.

Generator Installation in Concord — 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.

Can you install a battery instead of a generator in Concord?

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.

How much does a whole house generator cost in Concord?

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.

Do I need a permit to install a generator in Concord?

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.
