Generator Installation in San Rafael, CA

Public safety power shutoffs and storm outages made backup power a normal purchase in San Rafael rather than a luxury. The generator is the easy part. Deciding what it has to carry, and wiring the transfer equipment correctly, is the job.

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 San Rafael

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 San Rafael 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.

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.

Reviews from Marin County

Flickering through the whole house turned out to be a loose neutral at the service. They found it in under an hour when two other companies had shrugged.

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.

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

Generator Installation in San Rafael — questions

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 San Rafael?

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 San Rafael?

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

Can you install a battery instead of a generator in San Rafael?

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.

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.
