Two Generac home standby generators installed side by side at an Atlanta home

What it does

Power that turns on by itself

A standby generator sits outside your home on a pad, like an A/C unit. It's connected to your natural gas line or a propane tank, and to your electrical panel through an automatic transfer switch.

When the power goes out, it starts on its own and takes over in seconds, whether you're home or not. When the power comes back, it shuts itself off.

Pick what stays on

Just the essentials, or the whole house

Some families want the fridge, the furnace, a few lights and the Wi-Fi. Others want the whole house to run like nothing happened. Both are fine. We size the generator to the way you live.

Heating and air conditioning
Refrigerator and freezer
Lights, outlets and Wi-Fi

Questions about generator installation

Your generator questions, answered

How much does it cost?

Every home is different. The price depends on the generator size, how far it sits from your gas meter and electrical panel, whether you need a propane tank, any panel work, and what your permit requires. After a free site visit, James gives you a written estimate that spells out the equipment, installation and extras. No hidden fees and no pressure.

How long does installation take?

We'll give you a timeline with your estimate, based on equipment availability and permit timing where you live.

Do I need a permit?

Yes. We pull it and schedule the inspection with your city or county.

Natural gas or propane?

Both work well. If you have natural gas, we connect to your line. If not, we install a propane tank.
