Which Kohler generators do you install?

We install KOHLER home standby generators from 10 to 26 kW in the air-cooled range and 24 to 60 kW in the liquid-cooled range. Every unit runs on natural gas or propane. The air-cooled models make a little less power on natural gas, and the larger liquid-cooled models are rated about the same on both fuels.

What sets Kohler apart?

Every KOHLER home generator carries a five-year limited warranty, and on the 26RCA it covers parts, labor and travel. The enclosures are rated for 181 mph winds, which matters on the coast. Kohler says its home generators and engines are designed, engineered and assembled in the USA.

The KOHLER Energy Management app lets you check the generator from your phone. PowerBoost helps the generator start large loads such as an air conditioner without dropping power to the rest of the house, and a load shed kit can manage more.

Who does the work?

We manage the project from the site visit to startup. A licensed electrician wires the generator and transfer switch, a licensed gas fitter runs the gas line, and we schedule the electrical, gas and any fire department inspections. See generator permits in Massachusetts for what each one covers.
