Generac whole-home generators for Middle Tennessee.
When ice storms or summer thunderstorms knock out power in Williamson County, a standby generator turns the lights back on in seconds, automatically. We size, install, and maintain Generac systems that run your whole home, not just a few outlets.
Why we install Generac standby generators.
Generac builds the most widely installed residential standby generator in the country, which means proven reliability, readily available parts, and factory-backed warranty support. A Generac system sits outside on a concrete pad, ties into your natural gas or propane line, and starts itself within seconds of an outage. No extension cords, no refueling, no rolling a portable unit out of the garage in the dark.
Every visit includes
- Free in-home load assessment
- We calculate your actual electrical load, including HVAC, well pumps, and refrigerators, so the generator is sized right the first time.
- Whole-home and essential-circuit options
- Cover everything in the house, or just the circuits that matter most. We design the system around how your family actually lives.
- Automatic transfer switch
- The system detects an outage and switches your home to generator power in about ten seconds, whether you are home or not.
- Permits and code compliance handled
- We pull the required permits with Williamson County and your city, and coordinate gas line and electrical work to code.
- Concrete pad and clean install
- Set on a proper pad, plumbed into your gas or propane supply, with a finished look that fits your home.
- Maintenance and repair
- Generators need annual service like any engine. We maintain and repair the systems we install, and service units other contractors put in.

Most Williamson County calls get a same-day appointment. No pressure quotes, no upsells.
Middle Tennessee weather is the reason.
Ice storms in February, straight-line winds in spring, severe thunderstorms all summer. Williamson County loses power more often than most homeowners expect, and outages that last hours put refrigerated food, sump pumps, medical equipment, and home offices at risk. A standby generator is the difference between riding out the storm and checking into a hotel.

Questions, answered.
How much does a whole-home Generac generator cost installed?+
Pricing depends on the generator size, fuel type, gas line or propane work, and electrical upgrades your home needs. We do a free in-home load assessment and give you a written quote before any work begins, so you know exactly what to expect.
What size generator do I need for my home?+
It depends on your electrical load. Most Williamson County homes need a 22kW to 26kW unit to run the whole house including the HVAC system. Smaller essential-circuit systems start around 10kW. We measure your actual load during the site visit instead of guessing.
Does a standby generator start automatically when power goes out?+
Yes. The automatic transfer switch senses the outage and starts the generator within about ten seconds. When utility power returns, it switches back and shuts the generator down. You do not have to be home.
What fuel does a Generac standby generator use?+
Natural gas or liquid propane, whichever your home has. Natural gas is the most common setup in Brentwood and Franklin since it never needs refueling. Propane works well for homes outside the gas service area.
Do I need a permit for generator installation in Williamson County?+
Yes. Generator installations require electrical and gas permits, and the unit must meet setback and noise requirements. We handle all permitting and inspections as part of the installation.
How often does a standby generator need maintenance?+
Once a year, or after every 100 to 200 run hours. Annual service includes oil and filter changes, battery testing, and a full system exercise. We offer maintenance plans so it is handled automatically.
Can a generator run my air conditioning?+
Yes, when the system is sized for it. Whole-home units in the 22kW and up range can carry a central AC system. This is exactly why the load assessment matters: your HVAC system is usually the largest single load in the house.
How long does installation take?+
Most installations are completed in one to two days once the equipment arrives. Lead times on the generator itself vary, so we schedule the site assessment as early as possible.
