Start a Standby Generator Installation Business

1. 1

   Lock down the license before anything else

   A permanent standby generator is a wired electrical system with a fuel connection and an automatic transfer switch, governed by the National Electrical Code and NFPA standards. In every state that means a licensed electrical contractor pulls the permit and signs the work, and gas connections need their own permit. If you are not licensed, your first move is either to get licensed or to partner with a contractor who is; there is no legal path around it.

2. 2

   Become an authorized dealer for a major brand

   Generac, Kohler, Cummins, and Briggs run dealer programs that bring warranty authority, training, co-branded leads, and better unit pricing than buying retail. Dealer status is also what lets you honor manufacturer warranties, which customers ask about. Start the application early because approval and training take weeks.

3. 3

   Learn to size and quote correctly

   The quote is the business. You calculate the home or facility load, pick the unit (a 22kW to 26kW air-cooled unit covers most whole homes; commercial jobs jump to liquid-cooled units), and price the full scope: unit, transfer switch, pad, conductors, fuel line, permits, and inspection. A fully installed residential job commonly lands between $8,000 and $16,000 or more, with labor alone at $4,000 to $7,000, so a wrong estimate eats a whole job's profit.

4. 4

   Build the install and inspection workflow

   Site visit and load calc, permit, order the unit, pour or set the pad, run gas and electrical, set the transfer switch, then the manufacturer startup and the AHJ inspection. Document each step. The inspection sign-off is what closes the job and protects you if anything fails later.

5. 5

   Sell where the fear is

   Every prolonged outage, heat-driven brownout, and news story about grid emergency orders is a demand signal in your service area. Google Business Profile, a simple quote-request page, and referrals from HVAC and electrical partners fill the calendar. In storm and heat regions, seasonal urgency does the selling for you.

6. 6

   Add maintenance to smooth the revenue

   A standby unit must actually start when called, which means annual service and periodic testing. Offer maintenance plans to every install customer: it turns a one-time job into a recurring relationship, keeps their warranty valid, and gives you a book of service revenue between install seasons.
