Standby generators in Winchester & the surrounding counties

Generator installation so the lights stay on in the next storm.

Ice storm, summer thunderstorm or a long outage? A Generac whole-home backup generator starts on its own when the power goes out and keeps your heat, well pump, fridge and lights running. Our Winchester team installs them.

Available in: Winchester & the surrounding counties

Standby generators

“Every time the power goes out, the well pump and the heat go with it.”

Out in the counties, a long outage means no water, no heat and a fridge full of food at risk.

A standby generator sits outside on a pad, runs on natural gas or propane, and starts automatically through a transfer switch when the power fails. Within seconds, the circuits you've chosen are back on, whether you're home or not.

Our Winchester team installs Generac backup generators, with a 5-year limited manufacturer warranty. Your technician helps you decide what to keep running, sizes the generator to match, and runs and tests the gas line. The transfer switch and electrical connection are handled by a licensed electrician, and we coordinate the schedule.

Generac backup generators

Why a Generac whole-home backup generator

We install Generac, and only Generac. Here's what that gets you.

Sized to what you want running

Smaller homes often need a 10 to 18 kW unit. Larger homes, or homes with more than one AC system, usually need 22 to 28 kW. We size it to your list.

It checks itself every week

A short, quiet self-test at low speed keeps the engine ready, so you're not left finding out in an outage.

Check on it from your phone

Generac's Mobile Link app shows its status and maintenance alerts, home or away. Some features need a subscription.

Built for winter starts

Designed to start in the cold, with a roof that sheds snow and ice. Made for Shenandoah Valley winters.

Sizing

What do you want to keep running?

Generator size comes down to this one question.

Essentials

Essential circuits

Heat, well pump, sump pump, fridge, some lights and outlets. A smaller generator and a lower price.

Whole home

Whole-home backup

Everything runs as normal, including AC and the kitchen. A larger generator, with a load-managing transfer switch where needed.

Fuel

Natural gas or propane

Natural gas runs as long as the utility supply does. Propane, common out in the counties, needs a tank sized for long outages. We size and run the gas line either way.

The transfer switch: what makes it automatic

Every standby generator connects through an automatic transfer switch. When the power drops, it disconnects your home from the utility lines and starts the generator, usually within seconds, then switches back when the power returns. It also stops generator power from feeding back into the lines. A licensed electrician installs it, and we schedule the gas line, pad and electrical work together.

Generator FAQs

Questions about standby generators

Cost, placement and the transfer switch.

How much does a whole-home backup generator cost to install? +

It depends on the size of the generator, the fuel, the length of the gas line and the electrical work. In-home estimates are free, and you get a written price before any work starts. Financing is available on jobs of $500 or more.

How far does a generator need to be from the house? +

Manufacturers and local code set minimum distances from windows, doors, vents and other openings, usually a few feet. We place it to meet those rules and keep exhaust away from the house.

Can a homeowner install a generator transfer switch? +

It should be done by a licensed electrician. The transfer switch keeps generator power from feeding back into the utility lines, which protects line workers and your equipment.

Natural gas or propane: which is better? +

Natural gas runs as long as the utility supply does, with no tank to refill. Propane works anywhere but needs a tank sized for long outages. We'll recommend what fits your property.

Do you install generators in Norfolk or Wilmington? +

Standby generators are installed and serviced by our Winchester branch. In Norfolk and Wilmington, our plumbers can still run the gas line to a generator your electrician installs.
