When the grid quits, you don't
Whole-Home Generator Installation in Gilbert, AZ
Every monsoon season, storms knock out power somewhere in the East Valley. In most places an outage is an inconvenience. In an Arizona July, a dead air conditioner turns your house into an oven within hours. A whole-home standby generator ends that problem: when utility power drops, it starts itself, picks up the load, and carries your home until the grid comes back.
AC/DC Electric installs standby generator systems for homeowners in Gilbert and across the East Valley. We handle the load calculation, the automatic transfer switch, the panel work, and the permit, and we coordinate placement and fuel hookup so the project lands as one job — not five contractors pointing at each other.
Watch for these
Signs standby power belongs at your house
- Summer outages leave your house cooking
- Someone at home relies on powered medical equipment
- You work from home and outages cost you money
- You have lost a freezer full of food before
- Dragging out the portable every storm got old
- Your neighborhood sees regular flickers and brownouts
Sizing matters more than the brand
The number one job in a standby install is the load calculation. Air conditioning is the heavy hitter in Arizona — and it is the compressor's starting surge, not its running draw, that decides how big your generator must be. Undersize it and it stalls the moment the AC calls for power. Oversize it and you paid for capacity you will never use. We run the math on your actual panel and your actual equipment before recommending a unit.
You also do not have to power everything. Plenty of homeowners choose an essential-circuits setup — AC, refrigerator, some lights, the garage door — for a smaller generator and a smaller price. We lay out both options with flat pricing so you can decide with real numbers in front of you.
What the install involves
A standby generator is permanent equipment. It sits on a pad with code-required clearance from windows and property lines, connects to a fuel supply, and ties into your electrical system through an automatic transfer switch. That switch is the safety heart of the system — it isolates your home from the grid so your generator can never backfeed the utility lines. Permits and inspection are part of the deal, and we handle them. If your panel is aging, this project is often the right moment to deal with it; see electrical panel upgrades.
Why AC/DC Electric
A generator install touches your panel, your service, and your family's safety — exactly the work you want a licensed, bonded, and insured contractor doing. AC/DC Electric quotes the whole project flat before work starts, so the finish price matches the start price. And once your system is in, you have a 24/7 electrician on call who already knows your setup.

FAQ
Straight answers
Will a standby generator run my air conditioner?
Sized correctly, yes — in Arizona that is the whole point. The AC's start-up surge is the limiting factor, so the load calculation has to account for it. Some setups add a soft-start device to the AC so a smaller generator can carry it. We will tell you exactly what your equipment needs before you buy anything.
Does it really start by itself?
Yes. The automatic transfer switch watches utility power constantly. When the grid drops, it starts the generator and moves your home onto it — no cords, no switches, nothing for you to do. Expect a brief gap measured in seconds, then power is back. When the utility returns, the system transfers back and shuts itself down.
Do I need a permit for a standby generator in Gilbert?
Yes. Permanent generator installations are permitted electrical work, and inspection is part of the process. That is a good thing — a second set of eyes confirms the transfer switch isolates your home the way it must. We pull the permit and schedule the inspection as part of the job, included in your flat quote.
What is the difference between this and a portable generator?
A standby unit is permanent: it starts itself, runs on your fuel supply, and can carry the whole house. A portable is cheaper but manual — you roll it out, fuel it, start it, and power selected circuits. If portable fits your budget better, we do that work too.
