Owner pros and cons
Generac Guardian 14kW
- +No natural-gas derate — 14kW on either fuel

- +True Power <5% THD is safe for electronics
- +Mobile Link Wi-Fi status and alerts included
- −Transfer switch not included at this price
- −Support is dealer-dependent; owners advise picking the dealer with the best service reputation
- −Needs load-shedding to handle larger AC units
- −Install quotes routinely add $4,000-8,000 on top of the unit
Kohler 14kW RCA
- +Hydraulic lifters mean no valve adjustments for life
- +Aluminum enclosure genuinely resists coastal corrosion
- +33kVA surge starts large AC units other 14kW units can't
- +5-year/2,000-hour warranty is stronger than Generac's hours-unlimited-but-vaguer terms
- +Long track record: owners report earlier Kohler 14kW units still running after nearly two decades
- −12kW on natural gas is a bigger derate than Generac's 14kW
- −67 dB at full speed (63 dB during the weekly exercise) — loud beside a patio
- −No built-in Wi-Fi; the OnCue Plus app needs an ethernet run or a wireless bridge
- −Fewer dealers means longer waits for service in some regions
- −Costs more than the equivalent Generac before install
