What a Whole-House Generator Install Includes

A standby generator is more than a box on a pad. It's a fully integrated system: properly sized generator, automatic transfer switch (ATS), service-rated disconnect, gas line, concrete pad, and panel integration. Done right, you don't even notice when the power goes out.

A typical standby generator install project by Nashville Electric Pros includes:

  • Load calculation and sizing — 14kW, 22kW, 26kW, or larger depending on what you want backed up
  • Automatic transfer switch (ATS) — service-entrance rated or sub-panel, whole-home or essentials
  • Concrete or composite pad — properly placed per code and manufacturer specs
  • Gas line installation — coordinated with a licensed plumber for natural gas or LP
  • Service-rated disconnect and grounding to current NEC
  • Panel integration — whole-home or essentials-only depending on capacity
  • Generator commissioning — self-test programming, app setup, run verification
  • Metro Nashville permit and inspection

Choosing the Right Generator for Your Home

Whole-Home vs Essentials

A whole-home generator backs up everything: HVAC, water heater, range, all outlets. An essentials system backs up a sub-panel of critical circuits — usually cheaper but more limited.

Sizing

A 14kW unit handles a small home with one A/C and basics. 22kW–26kW handles most full Middle TN homes with two HVAC units. 38kW–48kW for large homes with multiple HVAC units and high-load appliances.

Natural Gas vs LP

Natural gas means unlimited runtime — no tank to fill — but requires a city gas line. LP is the answer for rural Joelton, Whites Creek, and acreage homes without natural gas.

Brands

Generac is the most common, with the widest service network. Kohler builds excellent commercial-grade units. Briggs & Stratton offers solid value. We install all three.

Reasons Nashville Homeowners Add Standby Generators

The most common drivers we hear from Middle Tennessee homeowners.

Storm Outages

Severe weather in Middle TN regularly knocks out NES service for hours or days.

Work From Home

An outage in the middle of a meeting is no longer an option.

Medical Equipment

CPAPs, oxygen concentrators, and refrigerated medications need reliable power.

Sump or Well Pumps

Lose power, lose the sump pump, and the basement floods. Lose the well pump and there's no water.

Home Resale Value

Standby generators are a documented home value-add in the Nashville market.

Rural Properties

Joelton, Whites Creek, and outer Wilson County see longer outages on rural feeders.

Standby Generator FAQs

Common questions about standby generator install in Nashville.

How big a generator do I need?
It depends on what you want backed up. A 22kW unit handles a typical Middle TN home with two HVAC units. We do a load calc and recommend the right size — never oversold.
How long does the install take?
Most full installs complete in 1–2 working days, with gas line work sometimes adding a day. We coordinate everything.
Natural gas or LP?
If you have city natural gas, that's almost always the right answer — unlimited runtime. If you're rural, LP with a 250- or 500-gallon tank is the standard.
Do I need a permit?
Yes. Generator installs require Metro Nashville electrical and plumbing permits. We handle both.
How loud are they?
Modern units are around 65–70 dB at 23 feet — about as loud as a window A/C unit. Most homeowners barely notice them after the first few weeks.
What maintenance do they need?
Annual maintenance — oil change, filter, valve check, battery. We offer service plans, or you can use any factory-authorized servicer.
