Starting at $11,000
What does a standby generator cost?
Most whole-home installs in the Berkshires start around $11,000. The final number depends on the size of the unit, the site work, and whether you run on natural gas or propane. Here is how to ballpark it, then we confirm with a free on-site visit.

Generator size guide
Square footage is a starting point, not the whole story. A well pump, heat pumps, or an electric water heater can push a home up a size class. We run a load calculation on every quote.
| Home | Size | Typical unit | What it usually covers |
|---|---|---|---|
| Small home | Up to 1,500 sq ft | 10 to 14 kW, air-cooled | Heat, well pump, fridge, lights, internet |
| Medium home | 1,500 to 3,000 sq ft | 14 to 22 kW, air-cooled | The essentials plus most of the house and central AC |
| Large home | Over 3,000 sq ft | 22 to 26+ kW, often liquid-cooled | Whole home, heat pumps, a heated shop or barn |
