Generator Installation in Lake Mary, FL
Lake Mary grew from two railroad settlements, Bent’s Station and Belle Fontaine, takes its name from the wife of a minister who settled on the lake’s north shore, and incorporated on August 7, 1973. GenerX installs and services standby generators here from our nearest facility, part of our Orlando service area.

Lake Mary Pricing
What Does a Generator Cost in Lake Mary?
Whole home installs in the Orlando area typically run $7,000 to $25,000+. Here's where most Lake Mary 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 on every Generac air-cooled unit we install. Where a Florida Public Utilities main reaches your street, a natural gas connection typically adds minimal cost compared with a propane tank installation.
Because GenerX employs all labor in-house, we eliminate the third-party markup that drives up installation costs elsewhere. Our buying volume as Florida’s largest dealer means we get better equipment pricing than smaller dealers. The result: a higher-quality installation at a more competitive price, not a trade-off.

Frequently Asked Questions
Lake Mary Generator Questions, Answered
Does Florida’s 2026 permit exemption cover a Lake Mary generator?
No. The City of Lake Mary explains that HB803, in effect from July 1, 2026, lifts the permit requirement only for a limited set of non-trade projects on single-family homes, and that electrical, plumbing, mechanical and gas work always needs a permit. A standby generator is electrical work, and gas work too when it runs on natural gas or propane. GenerX pulls the permit with a licensed electrician and schedules the inspections. You sign the Notice of Commencement and provide a property survey.
Is Lake Mary on Duke Energy or FPL?
Both serve the city. Lake Mary’s list of important numbers carries outage lines for Duke Energy and for FPL, and FPL’s tariff includes Lake Mary among its Seminole County communities. Your bill tells you which; the generator and transfer switch work with either.
Can my Lake Mary generator run on natural gas?
Where Florida Public Utilities has a main on the street, yes; its tariff lists Lake Mary in its Seminole County service area. Other homes run the generator on propane from a tank on the property, and the free estimate confirms the fuel.
Do Lake Mary HOAs approve generators?
Most review them before work starts. GenerX hands the board a placement plan, the generator’s sound sheet and the screening it will get.
How fast can GenerX reach Lake Mary for repairs?
Lake Mary repair calls go out from our nearest facility. Our service department takes emergency calls 24/7, and a large outage brings GenerX crews in from around the state.
