Frequently Asked Questions
The 22kW model offers the best value at $607 per kW over 10 years. It provides whole-house backup power for most homes (3,000-5,000 sq ft) while maintaining the lowest cost per kilowatt. The 14kW is the best budget option for smaller homes.
Installation costs can vary by $2,000-$5,000 between contractors. Equipment pricing is more standardized, but dealers may offer different financing terms. Always get 3-4 quotes and compare total project costs, not just equipment prices.
While there's no federal tax credit for standby generators, some states and utilities offer rebates ($500-$2,000). Check with your local utility company and state energy office. Some areas offer emergency preparedness rebates.
With proper maintenance, Generac generators typically last 20-30 years. Commercial units may run longer with more frequent servicing. The engine is the primary wear component, but major overhauls aren't usually needed until 15-20 years with residential use.
Extended warranties ($600-$1,200) are worth considering for generators over 20kW. Most major issues occur after the 5-year mark. The warranty typically pays for itself if you need one major repair (control board, alternator, or engine work).
