What it is

A van-based service that does oil changes, tune-ups, carburetor cleaning, battery checks and repairs on portable and standby generators, with some parts and accessories sold on the side.

Your first three steps

Who pays

Homeowners, contractors, farms, small businesses and event crews who rely on a generator and want it ready when needed.

How it makes money

Flat fees for annual service visits and tune-ups, hourly or per-job repair charges, plus a markup on parts and accessories.
