Warranty
5-year standard, 10-year extended available ($600-$1,000)
Noise
60-69 dB at 23 feet

Noise-sensitive installations near bedrooms, patios, or property lines. Homes where the generator is visible and aesthetics matter. Homeowners willing to pay $1,000 to $2,000 more for a quieter, more refined product.
WATCH OUT
Smaller dealer network than Generac means service wait times can be longer in some areas. Check that a Kohler-authorized dealer operates within 50 miles of your home before committing.

BEST FOR
Homeowners who want to install a generator once and not think about it for 30 years. Properties with demanding environmental conditions (coastal salt air, extreme temperatures). Buyers who value durability over price.
WATCH OUT
Smallest dealer network of the four brands. In rural areas, finding a Cummins-authorized technician can be challenging. Unit pricing is mid-range, but limited dealer competition can mean higher installation quotes.

BEST FOR
Budget-conscious buyers who want a reliable generator at the lowest cost. Best value at the 10-16 kW tier. The 10-year standard warranty reduces long-term risk.
WATCH OUT
Briggs and Stratton went through bankruptcy in 2020 and now operates under new ownership (Husqvarna). The company has stabilized, but the product line is narrower than before. Limited model range above 20 kW. Dealer network is the smallest of the four brands.

Which Brand Should You Choose?
Generac or Briggs

Generac
Best price-to-feature ratio, largest dealer network, fastest service. Safe default.
