Watch Out For
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.
Cummins

$2,800 - $13,000

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 For
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.
Briggs and Stratton
Budget option with solid warranty
$2,000 - $5,000

10-year limited warranty (best standard warranty)
Noise Level
65-72 dB at 23 feet

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 For
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.

| Kohler | 5 years | 10 years ($600-$1,000) | Parts and labor | Non-authorized installer, improper fuel |
| Cummins | 5 years comprehensive | 10 years limited | Parts and labor (comprehensive), parts only (limited) | Non-authorized service, modifications |
| Briggs | 10 years limited | N/A (already 10 years) | Parts and labor years 1-2, parts only years 3-10 | Non-authorized installer, neglected maintenance |
Which Brand Should You Choose?
Lowest upfront cost
Generac or Briggs
Briggs is cheapest at 10-16 kW. Generac offers better value at 22+ kW with stronger dealer support.
Noise is a priority
Kohler
60 dB at idle is quieter than a normal conversation. Worth the $1,000-$2,000 premium near bedrooms or patios.
Maximum durability
Cummins
Commercial DNA, 30+ year lifespan. The "buy once, never think about it" option.
Best all-around
Generac
Best price-to-feature ratio, largest dealer network, fastest service. The safe default for most homeowners.
