When the power goes out, your home or business doesn't have to. Tri-Star Electric is an authorized Generac sales and service dealer serving Rochester and the Finger Lakes region. Our licensed electricians specialize in whole-home standby generator installation — providing turnkey service from the initial consultation all the way through permits, inspections, and final startup.

Why Choose a Standby Generator?

Unlike portable generators that require manual setup and fuel storage, a Generac home standby generator is permanently installed outside your home and turns on automatically within seconds of a power outage — 24 hours a day, 7 days a week, even when you're not home. Whether it's a summer thunderstorm, a winter ice storm, or a grid failure, your lights, heat, sump pump, refrigerator, and medical equipment keep running without interruption.

Upstate New York homeowners know better than most how unpredictable the weather can be. From lake-effect snowstorms in Rochester to ice storms across the Finger Lakes, extended power outages are a real risk every season. A Generac standby generator gives you the peace of mind that your family is protected no matter what.

Our Installation Process

We handle every step of the installation so you don't have to worry about a thing:

Free In-Home Consultation — One of our licensed electricians visits your home to assess your electrical panel, evaluate your power needs, and recommend the right Generac model for your home's square footage and appliances.

Generator Sizing — Choosing the right size generator is critical. A 10kW unit can power essential circuits in a smaller home, while larger homes typically require a 22kW or 24kW unit for whole-home coverage. We help you choose the right system for your needs and budget.

Permits and Inspections — Every generator installation in New York State requires permits and a final inspection. We handle all permit applications and coordinate inspections with your local municipality so the job is done right and up to code.

Natural Gas or Propane Connection — Generac standby generators run on your existing natural gas line or a propane tank. We coordinate with your gas utility and handle the connection as part of our turnkey installation service.

Automatic Transfer Switch Installation — The transfer switch is the brain of your generator system. It automatically detects a power outage and switches your home to generator power within seconds. We install and test the transfer switch as part of every installation.

Final Startup and Testing — Once installation is complete, we perform a full system test and walk you through how your new generator operates, including the weekly self-test cycle that keeps your system ready at all times.

How Much Does a Generac Generator Cost in Upstate New York?

Generator installation costs vary based on the size of the unit, your home's existing electrical setup, and local permit fees. In the Rochester and Finger Lakes area, most whole-home standby generator installations range from $10,000 to $20,000 fully installed. Larger homes requiring higher-output units or more complex electrical work may fall toward the higher end of that range. Financing is available for qualified buyers, making it easier than ever to protect your home without a large upfront investment.

Generac Generator FAQs

How much does a Generac generator cost installed in Rochester?

Most whole-home standby generator installations in the Rochester and Finger Lakes area run $10,000 to $20,000 fully installed. The final price depends on generator size, your home’s existing electrical service, gas line work, and local permit fees. We provide a firm written quote after a free in-home consultation, and financing is available for qualified buyers.

What size generator does my home need?

It depends on what you want to keep running during an outage, from essentials like your furnace, sump pump, and refrigerator to whole-home coverage including central air. The Generac home standby generators we install range from 10 kW to 28 kW. We perform a load calculation during your consultation so you get the right size without overpaying.

Does a standby generator run on natural gas or propane?

Either one. If your home already has natural gas service, we connect the generator to it so you never have to refuel. Homes without natural gas can run on a propane tank sized for extended outages. We coordinate the fuel connection as part of the installation.

How long does installation take?

Most generator installations are completed in one day. Before install day, we handle the permits and coordinate with your gas utility, and we schedule the inspection afterward.

Do I need a permit for a standby generator?

Yes. A standby generator requires an electrical permit and inspection, and usually a gas permit as well. Tri-Star Electric pulls all permits and schedules the inspections, so you never have to deal with the town.

What happens when the power goes out?

The automatic transfer switch senses the outage and starts your generator within seconds, whether or not you’re home. When utility power returns, the system switches back and shuts the generator down on its own.

Do you service generators you didn’t install?

Yes. As an authorized Generac service dealer, we service and maintain all Generac home standby generators, including units installed by other companies. Annual maintenance keeps your generator ready, and the unit runs a brief self-test every week.

Do you offer any discounts?

Yes. We offer discounts for veterans and first responders. Ask about current offers when you schedule your free consultation.
