Generac standby generators done right, here in Rockland County
Choosing the unit is the easy part; getting it sized, permitted, and wired to code is where it counts. Once you've decided, our Generator Installation team handles the pad, the gas hookup, the automatic transfer switch, and the township inspection — so the system you picked actually performs the night you finally need it.
- Automatic — senses the outage and transfers in seconds, no cords or refueling
- Guardian (air-cooled, 10–26kW) for most homes; Protector (liquid-cooled) for large ones
- Runs on the natural gas or propane you already have, for days on end
- Sized by a real load calculation to power exactly what you want kept on
Why Rockland County trusts our standby generators
Across Rockland County, a standby generator is the difference between riding out a nor'easter in a warm, lit home and waiting days in the dark for the utility to catch up.
Truly hands-off
It senses the outage, starts itself, and powers the house within seconds — you never touch it, even at 3 a.m. in a blizzard.
Runs for days, not hours
Tied into your gas line, a standby unit runs continuously through a multi-day outage — no refueling, no cords, no late-night gas-can runs.
Sized to your real needs
A load calculation matches the unit to your home, so you power what matters without overpaying for capacity you'll never use.
Quiet and built to last
Modern Generac units run quietly and are built for years of New York winters — with Mobile Link so you can check status from your phone.

Your Generac standby generators, step by step
A clear, no-surprises process — here's exactly what to expect, from start to finish.
Constant Watch
The unit monitors utility power around the clock, sitting idle but ready while it waits for the grid to fail.
Automatic Start
The moment the grid drops, the engine starts on natural gas or propane — no button to press, no cords to run.
Whole-Home Transfer
The automatic transfer switch safely disconnects from the grid and powers your circuits within seconds.
Run & Return
It runs as long as the outage lasts, then transfers you back to utility power and shuts down on its own.

Frequently asked Standby Generators questions in Rockland County, answered
A portable generator is wheeled out during an outage, fueled by gas cans, and connected with cords to a few appliances. A standby generator is permanently installed beside your home, wired into your electrical panel, fueled by natural gas or propane, and starts automatically — powering your whole house with no effort from you.
It depends on what you want running during an outage. Many Rockland County homes do well on an 18–24kW Guardian for whole-home coverage, while an essential-circuits setup — furnace, fridge, well pump, a few outlets — can run on 10–14kW. We run a free load calculation and recommend the right size, never more than you need.
Generac standby units run on either. If your home has a natural gas line, the generator ties directly into it for effectively unlimited runtime. If not, it runs on a propane tank. We confirm the best fuel for your property and size the line during the assessment.
On natural gas, effectively as long as the outage lasts — there's no tank to empty. On propane, runtime depends on tank size and load, often several days. Either way it far outlasts a portable generator you'd be refueling every few hours through the night.
Yes. The generator watches the grid 24/7, starts within seconds of an outage, transfers your home to backup power, and switches back when utility power returns — then shuts itself off. A weekly self-test keeps it ready, so you never have to think about it.
