Whole house generator installation in Los Angeles
When the power goes out, most homes go dark and wait. A home with a standby generator does not. Within seconds the generator starts on its own, the transfer switch moves the house over to it, and the lights, the fridge, the internet and the heating or cooling keep running. You often notice the outage only because a neighbour mentions theirs. That is the whole point of a proper standby system, it works without you doing anything.
A.D.I. Electrical Services is a licensed C-10 electrical contractor, LIC# 977443, installing whole house generators across Los Angeles and the west San Fernando Valley. Our shop price is $4,995 for a whole house generator including installation, and we quote your exact job after seeing the site.
Why generators matter more here now
Two things have made backup power a real consideration in this part of Los Angeles. Public Safety Power Shutoffs, the planned outages the utility runs during high fire-risk weather, can cut power for hours or days with little notice, and the hills above Calabasas and the west Valley are squarely in that zone. On top of that, ordinary grid outages during heat waves are more common when everyone’s air conditioning is running at once. A standby generator covers both. It does not care why the power is off. It just restores it.
Standby, not a portable
There is a real difference between a portable generator and a standby system, and it is worth being clear about. A portable generator is something you drag out, fuel, start by hand, and run extension cords from, and it cannot power your whole home safely. A standby generator is installed permanently outside the house, wired into your electrical system, and it starts automatically when the power drops. You do not have to be home, awake, or even aware. For a house you actually live in, the standby system is what most people want once they understand the difference.
The automatic transfer switch is the key part
The heart of a safe generator installation is the automatic transfer switch. It watches the utility power, and the moment it fails, it disconnects your home from the grid and connects it to the generator. That disconnection is not optional. It is what stops your generator from feeding power back into the utility lines, which is a serious danger to the crews working to restore power. A generator wired without a proper transfer switch is both illegal and dangerous. As a licensed contractor, fitting the transfer switch correctly is central to what we do, and it is one of the main reasons this is not a job for an unlicensed installer.
Sizing the generator to your home
A generator has to be sized to what you want it to run. Some homeowners want the essentials covered, the fridge, some lights, the internet and one heating or cooling zone. Others want the whole house to run as normal, including central air conditioning, which draws a lot of power at startup. The right generator for a home that needs to keep the AC running is larger than one covering essentials only. We work out what you want backed up, calculate the load including the surge when large equipment starts, and size the generator to it. Undersizing leaves you in the dark when the big loads kick in, so this step matters.
Fuel, placement and permits
A standby generator runs on natural gas or propane, and where it sits matters. It needs clearance from windows and doors, a stable base, and a safe connection to the fuel supply and to your electrical panel. Placement also affects the neighbours and has to meet local rules. Generator installations are permitted and inspected work, and in the cities around here, including the City of Calabasas and the City of Los Angeles, that process is not optional. We handle the permit, the placement, the electrical connection and the fuel side, and we leave the system ready to pass inspection and run when you need it.
Your panel may need attention first
A generator ties directly into your electrical panel, and an old or undersized panel can complicate the install. If your home still has a Federal Pacific Stab-Lok or a Zinsco panel, or a 60 to 100 amp service that is already stretched, we will tell you plainly whether the panel needs to be addressed as part of the work. A 200 amp panel upgrade starts at $1,949 in our shop. We would rather raise it before we quote than surprise you with it halfway through.
What the visit and quote involve
We come out, look at your panel and service, talk through what you want to keep running, check where the generator can safely sit and how the fuel gets to it, then give you a firm price. The shop price of $4,995 including installation is the starting point for a standard whole house generator. Your final number depends on the generator size your home needs, the transfer switch, the fuel connection, the placement and whether the panel needs work. You get that number before anything begins.

Frequently Asked Questions
Our shop price is $4,995 for a whole house generator including installation, which is the starting point for a standard install. The final price depends on the generator size your home needs, the automatic transfer switch, the fuel connection, placement and whether your panel needs work. We give a firm quote after seeing the site.
Yes, you need one. The automatic transfer switch disconnects your home from the utility and connects it to the generator the moment the power fails. It is what starts the generator automatically and, critically, what stops power from feeding back into the utility lines and endangering repair crews. A generator without a proper transfer switch is illegal and dangerous.
It can, if it is sized for it. Central air conditioning draws a large surge of power when it starts, so a home that wants the AC kept running needs a larger generator than one covering essentials only. We calculate the load, including startup surge, and size the generator to what you want to run.
For a home you live in, yes. A portable generator has to be dragged out, fuelled and started by hand, and cannot safely power a whole home. A standby generator is installed permanently, wired into your electrical system, and starts automatically when the power drops, whether or not you are home.
Yes. Generator installations are permitted and inspected work in the City of Los Angeles, the City of Calabasas and the surrounding jurisdictions. As a licensed C-10 contractor we handle the permit, the placement and the electrical and fuel connections, and leave the system ready to pass inspection.
These communities are in the high fire-risk zone where the utility runs Public Safety Power Shutoffs, planned outages during dangerous fire weather that can last hours or days. A standby generator keeps the home running through those shutoffs and through ordinary grid outages during heat waves.
