Horn Lake Pricing
What Does a Generator Cost in Horn Lake?
Whole home installs in the Memphis area typically run $7,000 to $25,000+. Here's where most Horn Lake 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 Atmos Energy where a connection is available; 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.
