14RCA

Power: 14kW LP / 12kW NG
Installed Cost: $9,000–$13,000
Noise: 69 dB (63 dB exercise)
Weight: 440 lbs
Warranty: 5 years
Fuel: Dual-fuel (NG/LP)

Best for: 1,500–2,000 sq ft homes where premium build quality matters more than price.

The 14RCA is where Kohler's residential lineup begins, and it immediately feels different from the competition. At 440 lbs, it's 55 lbs heavier than the Generac 14kW; that extra weight is thicker aluminum, a more robust enclosure rated to 181 mph winds, and the Kohler CH740 V-Twin.

What This Generator Keeps Running

On propane (14 kW): 2-ton central AC with essentials. 33 kVA motor starting handles AC surges well.

Limitations: On natural gas (12 kW): AC becomes tight. The 14% NG derating is steeper than Generac (0%) and Cummins (0%) at this size.

What It Actually Costs

$4,899

Installed

$9,000–$13,000

About $1,000 more installed than a comparable Generac 14kW once you add the separately purchased ATS. The free 10-year warranty promo offsets a significant portion.

Frequently Asked Questions

Is the Kohler 14RCA worth the premium?▾

On propane, performance matches Generac (14 kW). You're paying $1,000 more for heavier construction, quieter exercise (63 vs 65 dB), and potentially free 10-year warranty. On NG, the Kohler drops to 12 kW while Generac holds at 14 Generac is the better NG value at this size.

How does the 14RCA perform on natural gas?▾

12 kW: a 14% reduction from propane. Enough for essentials and a small AC, but tight for a 2-ton system with other loads. On NG, the Generac 14kW (14/14) or Cummins RS13A (13/13) offer more capacity.

Does Kohler include the transfer switch?▾

No. Kohler always sells the ATS separately. RXT 100A SE: $599–$719. 200A: ~$789. Factor this into your total cost when comparing against brands that bundle it.
