Generac Generator Installation in Middle Tennessee
When the power goes out in Spring Hill, Franklin or anywhere in Middle Tennessee, a Generac home standby generator turns itself on in seconds. Your lights, HVAC, fridge, sump pump and Wi-Fi keep running whether you are home, asleep or out of town.
Summit Electric & Plumbing sells, installs and services Generac generators from start to finish. We size the unit to your home, pull the permits, handle the wiring and transfer switch, and give you one upfront price before any work begins.

Sound Familiar?
Middle Tennessee gets it all: spring tornado warnings, summer thunderstorms, and winter ice that brings down lines for days. When the grid fails, it’s usually at the worst possible moment.
You shouldn’t have to worry about keeping the lights on. A whole-home Generac generator protects your home, your schedule and your family, so the next outage is a non-event.
Why Homeowners Choose a Generac Whole-Home Generator
Generac is the most trusted name in home backup power. Pair it with a local, licensed team that installs it right and stays around to service it, and you never have to think about an outage again.

Frequently Asked Generator Questions
Thinking about a standby generator for your Middle Tennessee home? Here are the questions we hear most. For answers specific to your house, call Summit at (615) 433-5555.
Every home is different. The price depends on the generator size you need, natural gas vs. propane, the distance from your gas meter and electrical panel, and whether your panel needs upgrades. After a quick in-home visit, Summit gives you one upfront, all-in price with the generator, transfer switch, pad, permit and installation included. Financing through Synchrony is coming soon, too.
Most homes in our area are well served by a Generac air-cooled standby generator in the 14 to 26 kW range. Larger homes or homes with several AC units may need a bigger unit or load management. We calculate your actual electrical load instead of guessing, so you get the right size, not the most expensive one.
The installation itself is usually completed in a single day. The overall timeline depends on permitting and inspection schedules, which vary between cities like Franklin, Spring Hill and Murfreesboro and unincorporated county areas. We’ll give you a realistic schedule before we start.
Yes. Standby generators require an electrical permit and inspection. Who issues it depends on whether your home is inside city limits (cities such as Franklin, Spring Hill and Murfreesboro issue their own) or in an area covered by the state. Summit pulls the right permit and schedules the inspection for you.
No. When we say automatic, we mean it. The automatic transfer switch senses the outage, starts the generator and moves your home over to backup power, usually within seconds. When utility power comes back, it switches back and the generator shuts itself off.
A Generac home standby generator runs on your home’s natural gas service or a propane (LP) tank. Because it’s connected to a permanent fuel supply, there’s no refueling or gas cans during an outage.
Yes, if it’s sized for it. We design whole-home systems so you stay cool in a Tennessee summer and warm during winter ice storms, and can go on with life as if nothing happened.
Your generator runs a short self-test on a regular schedule to confirm it’s ready, without interrupting your power. Most Generac models also include Wi-Fi monitoring so you can check its status from your phone. We set it up during your walkthrough.
Plan on maintenance at least once a year, even if it hasn’t run much. That includes oil and filters, a battery test and an inspection of the transfer switch and connections. Summit offers annual generator maintenance so you never have to think about it.
A standby generator ties directly into your electrical panel and gas service, so it should be installed by a licensed electrical contractor. Big-box stores sell generators but usually hand the installation to a third-party subcontractor. With Summit, the same local team sizes, installs, inspects and services your generator.
