Kohler home generators (now made by Rehlko, the renamed Kohler Energy) are the main alternative to Generac for whole-home standby. The RCA series runs 10 to 26 kW, carries a 5-year / 2,000-hour warranty that covers parts, labor and travel for the whole term, and uses OnCue Plus for remote monitoring.
| MODEL | OUTPUT | FITS |
|---|---|---|
| 10RCA | 10 kW | Essential circuits |
| 14RCA | 14 kW | Essentials plus one AC |
| 20RCA | 20 kW | Whole-home, most single-AC houses |
| 26RCA | 26 kW | Whole-home, two AC systems |
Expect Kohler to land a little higher than Generac at the same kilowatts; the warranty is where the difference goes. Ranges include the transfer switch, pad, electrical and gas permits and a standard fuel run. The in-person estimate is free.

Yes. We are a licensed Florida electrical contractor (ER13014254) and we install, wire, permit and commission Kohler home standby generators and transfer switches across Orange, Seminole, Osceola and Lake counties. We size on your real load first, then recommend the unit.
Plan on $6,500–$9,500 for an essential-circuits standby (10–14 kW) and $9,500–$18,000 for whole-home (18–26 kW), including the transfer switch, pad, electrical and gas permits and a standard fuel run. Expect Kohler to land a little higher than Generac at the same kilowatts; the warranty is where the difference goes. The estimate is free and in person.
Essentials (fridge, lights, Wi-Fi, a well) fit in 7.5–10 kW. Add one central AC and you are at 13–14 kW. Whole-home with two AC systems is 22–26 kW. We run a load calculation on site instead of guessing from square footage.
On a level pad outside, with the manufacturer's clearances — typically 18 inches from the house, 5 feet from any window, door or vent, and clear of the AC condenser and gas meter. Orlando-area HOAs often want it screened and on the side yard; we handle the approval paperwork with you.
Kohler is built heavier and its warranty covers labor and travel for all five years; Generac has the bigger service network and costs less installed. In Orlando both are good choices. If you want the quietest unit and the fullest warranty, Kohler; if you want the lowest price and the fastest parts, Generac.
Rehlko, the company formerly called Kohler Energy, spun out of Kohler Co. in 2024. The generators still carry the Kohler name and the same dealer warranty.
The OnCue Plus app is included with RCA generators; it needs a wired or Wi-Fi internet connection at the generator, which we provide for during the install.
