- Best warranty: Kohler, 5-year parts + 5-year labor

Brands HVAC Comfort Installs
HVAC Comfort installs three generator brands in Michigan: Kohler, Generac, and Briggs & Stratton.
Warranty Comparison
The three brands have very different warranty coverage, and this is where the brand decision matters most.
- Kohler: 5-year parts, 5-year labor
- Generac: Tiered parts only, no labor coverage
- Briggs & Stratton: Tiered parts only, no labor coverage
Kohler stands out because its warranty covers both the parts and the labor for five years. With Generac and Briggs & Stratton, the warranty covers eligible parts, but labor costs are not included. If a covered component needs to be repaired or replaced, you may still have to pay for the technician’s time.
For Michigan homeowners comparing generator brands, that difference can affect the long-term cost of owning the system. HVAC Comfort recommends Kohler for many homeowners because the five-year labor coverage provides additional warranty protection beyond the generator’s parts.
