Brentwood Pricing
What Does a Generator Cost in Brentwood?
Whole home installs in the Nashville area typically run $7,000 to $25,000+. Here's where most Brentwood homes land.
Essential circuits (lights, fridge, AC unit)
Most homes under 3,000 sq ft (full house)
Larger homes, multiple HVAC zones
Large homes, home offices, medical equipment
Prices include equipment, in-house installation, transfer switch, permit fees, and our 12-year warranty. Natural gas comes from Spire Tennessee across most of Brentwood and from Atmos Energy in the Sunset Road and Concord Road East area; propane is the alternative and adds a tank to the install.
Because GenerX employs all labor in-house, we eliminate the third-party markup that drives up installation costs elsewhere. Our buying volume across the Canter Power network means better equipment pricing than smaller dealers. The result: a higher-quality installation at a more competitive price, not a trade-off.

Frequently Asked Questions
Brentwood Generator Questions, Answered
Who issues generator permits in Brentwood?
Brentwood Planning and Codes at 5211 Maryland Way issues building permits, with online permitting available, and the Tennessee State Fire Marshal’s Office issues and inspects the electrical permit. GenerX pulls both with a licensed electrician and schedules the inspections.
What knocks out power in Brentwood?
Ice. The January 2026 ice storm cut power to 231,749 NES customers and left 23,479 Middle Tennessee Electric customers out at its peak.
Is natural gas available at my Brentwood address?
Often, yes. Spire Tennessee, the former Piedmont Natural Gas system, serves most of Brentwood, and Atmos Energy serves the Sunset Road and Concord Road East area. Where there is no gas main on your street, the generator runs on propane from a tank on your property. Your GenerX Field Engineer confirms which applies during the free estimate.
Will my Brentwood HOA allow a whole home generator?
Many HOAs require architectural approval before installation. We prepare the HOA packet for you: the site drawing, the sound sheet and the screening plan, so the board has what it needs to review.
How fast can GenerX reach Brentwood for repairs?
Brentwood is served from our facility at 107 B Flex Ave in Portland, north of Nashville, about 51 miles away, with parts stocked locally. GenerX offers 24/7 emergency repair, and in a large outage our statewide fleet deploys to Middle Tennessee.
