When storm season knocks out the power, a standby generator keeps your home running automatically. Here’s what a whole-home standby system costs installed in Florida.
Typical installed cost
A whole-home standby generator, professionally installed, generally runs $8,000 to $18,000+. The generator unit itself is only part of it — the transfer switch, electrical work, gas hookup, pad, and permitting all factor into the installed price.
What affects the price
- Generator size (kW) — how much of the home you want to power
- Automatic transfer switch and electrical tie-in
- Fuel source and gas line work (natural gas or propane)
- Pad, placement, and distance from the panel
- Permits and inspection
Whole-home vs. essentials
You don’t always need to power everything. A smaller system covering essentials — AC, fridge, well pump, key circuits — costs less than a whole-home unit. We’ll size it to what matters most to you.
