Generac is the name most homeowners think of first when they picture a whole-house generator, and for good reason: it has built home standby units since the company began in 1959, backs them with 24/7 support from its Wisconsin headquarters, and has one of the largest service networks in the country.

For Nashville and Middle Tennessee homes that usually means a Guardian Series air-cooled unit, with the larger XG and Protector liquid-cooled lines for big homes, estates and light commercial buildings, and PWRcell 2 batteries when you want solar and storage in the same plan. We help you pick the right size first and the right model second.

Where it shines

Wide range of sizes, from 10 kW air-cooled units to 48 kW liquid-cooled XG models
Automatic transfer switch options, including a whole-house switch and smart switch choices
Remote monitoring and alerts with Mobile Link, so you can see your generator from your phone
Weekly quiet self-test modes (Quiet-Test) on current units
Battery storage line (PWRcell 2) that pairs with solar for backup, savings and storm preparation
A large dealer and service-technician network, which matters long after install day

Honest tradeoffs

Good to know before you buy.

Things to keep in mind

The right size depends on your actual load (air conditioning, well pump, electric range), not on square footage alone. Use our size calculator before you shop.
Natural gas needs an adequate meter and gas line. Propane needs a properly sized tank. We check both during the site assessment.
Air-cooled units are efficient and compact; liquid-cooled units are built for larger loads and longer run times.

Best for

Homeowners who want the most familiar, widely supported option
Whole-house backup from 10 kW to 48 kW

Questions

Generac FAQ

Do you install Generac generators?

Yes. Generac is one of our two main focus brands, and we handle the full job: sizing, permits, pad, gas line, electrical, transfer switch, start-up and your walkthrough.

Which Generac size do I need?

It depends on the loads you want to keep running. Our Generator Size Calculator gives a planning range, and we confirm with a short site assessment before you buy anything.

What is the difference between Guardian, XG and Protector?

Guardian units are air-cooled home standby generators. XG and Protector are liquid-cooled lines for larger homes and light commercial use, with more capacity and different engine design.

Is Generac the right brand for me?

It is an excellent choice for most homes. We will also show you KOHLER and other options side by side so you can choose with confidence.
