Home Backup Generators

Install a Standby Generator at Your Massachusetts or Southern New Hampshire Home and Worry No More!

Home backup generators, also called standby generators, are incredibly valuable investments for homeowners in these parts. Severe weather, as we often experience (especially in winter), is the single leading cause of power outages, and the amount and severity of these outages has spiked dramatically over the past decade.

Do you have a plan when the power goes out? Batteries and candles may light the way, but they won't power the systems critical to your home, allow your lifestyle to continue normally, or even keep you warm when the temperature plunges.

A standby home generator changes all that, providing peace of mind during an outage—and the hours leading up to one—by keeping your power on while the lights of other go dark. The generator is installed outside (like an AC unit) and comes on automatically, whether you're home or away.

Standby generators start in seconds, restoring power to critical hard-wire systems such as heating, air conditioning, water heaters, sump pumps, well pumps, security systems, and large appliances. Plus, home generators run on propane or natural gas, so there's no refueling necessary.
