Generac warranty for generators & engines
The short version
Generac covers generators & engines in full for 1 year, then keeps parts only covered to 3 years. That full coverage is the same as most of the 12 brands we compared, which typically cover 1 year in full. Some of this coverage only applies if you register the product.
From Generac's published warranty, checked October 2026.
