Whole-House Generator Installation in Santa Rosa, CA
A whole-house generator means your home keeps running when the power doesn't — HVAC, well pump, kitchen, everything — without you deciding what to sacrifice. J&J Electric installs whole-house standby generators throughout Santa Rosa and Sonoma County, sized to your home's actual load and tested under that load before we call the job done.
- We calculate your real load, not a square-footage guess. So the generator you get actually carries what you need it to.
- We'll tell you honestly if whole-house is the right fit. For some homes, essential-circuit coverage is the smarter, more cost-effective choice.
- We test it before we call it done. Full load testing and commissioning, not just an install and a handshake.

What Is Whole-House Generator Installation?
Whole-house generator installation is the process of sizing, installing, and commissioning a standby generator built to power your entire home automatically during an outage — not just a few key circuits, but HVAC, well pump, kitchen, and everything else running at once. The system includes an automatic transfer switch that detects an outage and switches your home to generator power within seconds, without you doing anything manually. J&J Electric installs whole-house standby generators throughout Santa Rosa and Sonoma County under one C-10 license, #1078243, starting with a real calculation of your home's actual electrical load.
Our Process
Here's what happens after you call (707) 480-8331:
- You tell us about your home. Size, whether you're on a well, and what matters most to you during an outage.
- We calculate your full home load. HVAC, well pump, kitchen, and everything else that needs to run, so the generator is sized correctly — not guessed at.
- You get a written, itemized estimate. Generator unit, transfer switch, fuel line, pad, and permit costs broken down clearly.
- We pull the permit. Filed under our own license, with placement and inspection handled to code.
- We install the system. Generator placement, automatic transfer switch, and fuel supply connection — natural gas or propane, coordinated to what your property has.
- We test it under real load. Full load testing and commissioning before we call the job done, so you know it will actually carry your home when it matters.
How Much Does Whole-House Generator Installation Cost?
Whole-house generator cost depends mainly on the generator's size (measured in kW) and your home's electrical load, along with what's involved in the installation itself — the transfer switch, fuel line, concrete pad, and any panel work. A generator sized for a typical home costs less than one sized for a larger property or one requiring more extensive site work. We give you a written, itemized estimate before any work starts.
Whole-House vs. Essential-Circuits Backup — Which Do You Need?
Whole-house coverage runs your entire home during an outage — HVAC, well pump, kitchen, everything — without you choosing what to sacrifice. It's the right call for larger homes, properties on a well (since the pump needs power to function at all), and households with medical equipment that requires uninterrupted power.
Essential-circuits coverage powers a smaller, prioritized set of circuits — refrigeration, some lighting, key outlets — at a lower cost. For some homes, this is genuinely the smarter, more cost-effective fit.
We'll give you an honest read on which situation you're in rather than defaulting to the bigger system.

FAQ
Frequently Asked Questions
How much does whole-house generator installation cost?
It depends on the generator's size and what the installation involves — the transfer switch, fuel line, pad, and any panel work. You get a written estimate before work begins.
Will a whole-house generator really run my entire home, including my well pump?
Yes, when it's sized correctly — we calculate your full home load first, including well pumps and HVAC, then test the system under that actual load before calling the job done.
Do I need whole-house coverage, or would essential circuits be enough?
It depends on your home. Whole-house makes the most sense for larger homes, well-dependent properties, and households with medical equipment needing uninterrupted power. For other homes, essential-circuits coverage may be the more cost-effective right fit.
How fast does the power come back on during an outage?
An automatic transfer switch detects the outage and switches to generator power within seconds, without you needing to do anything manually.
What fuel does a whole-house generator use?
Most run on natural gas or propane, coordinated to whatever your property already has or can reasonably support.
Do I need a permit for a whole-house generator in Santa Rosa?
Yes — we handle placement, permit filing, and inspection under our own license.
How long does a whole-house generator last?
With proper maintenance, whole-house generators commonly last up to around 20 years, based on regional industry data.
Which generator brand should I choose?
Several reputable manufacturers make residential standby generators. We can walk you through the real differences based on your home's needs rather than pushing whichever brand is most convenient for us.
