MAIN 200AGenerator Installation in Fairfax, 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 Fairfax
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.
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 Fairfax homes land between 14kW and 26kW depending on AC, well pumps and electric ranges.

Reviews from Marin County
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 · FairfaxBreaker 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 · FairfaxKitchen breaker kept popping whenever we ran the microwave and kettle. They put in a dedicated circuit instead of just telling us to use one appliance at a time.
Alicia G.Dedicated circuit · FairfaxGenerator Installation in Fairfax — questions
Can you install a battery instead of a generator in Fairfax?
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.
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.
Do I need a permit to install a generator in Fairfax?
Yes, and often a gas permit too. We handle the electrical permit and inspection and coordinate with your gas contractor or plumber.
How much does a whole house generator cost in Fairfax?
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.
