Peace of mind especially in the winter months

Had generator for about 1 year and it has run during one power outage. I run it under load every couple of months for at least 1 hour to make sure the components are exercised and to stabilize the bearings and motor generator. It is important to break-in when it’s not an emergency!

Provides security

We Purchased the Generac system one month ago. With the recent storms in Wisconsin I felt so safe that if our power went out we had a backup system. Having a household with people with disabilities it is very important to have power to keep cool/warm, so the sump pump continues to work, the food will stay safe and cold and the medical equipment needed for saftey reasons will work. I no longer have to get out all the candles and flashlights when a storm is coming. I just sit back and relax knowing we will ALWAYS have power!!

Time saving, great device!

My wife t thought I was crazy for buying a stand-by generator because we have a generator that I double hook up to run a few things in the house. Now since we have the generac she sees how handy it is and I don't have to go outside in the freezing cold or rain in order to "hook up" the other one!

Excellent from installation to education

This is our second Generac as we recently moved to Florida and had to leave our other Generac behind. The feeling of security it provides, and the almost instant continuation of electric service to our home, is worth every penny of its price. Our Generac dealer made the entire process simple for us, taking care of each detail involved with the installation. The instructions provided were simple and clear, and they made sure we knew how to reach them with any questions or concerns we might have. Overall, the level of comfort having our Generac installed has made us more comfortable in our new home.

Reliable Backup Power

We have had our Generac Whole House 22KW generator for 2 years this month. It has performed perfectly. We have a lot of power outages in this area, and this generator has come to the rescue every time! It's the best investment I ever made!

Purchased this whole home generator two years ago and it has paid for itself already even though we have not experienced a hurricane during that period of time. 28 days without power after Katrina and 8 days without power after Ida!

Complete system

Purchase & Installation just completed this week. The season for power failures is a month away. Friends and neighbors have been very satisfied with their units and are the reason for any selection of a 24KWH unit.

Makes the neighbors jealous

A good unit. Once the leak was fixed My unit developed an oil leak shortly after installation Contacted Generac they sent a dealer mechanic out. I believe the oil leaks fixed. I gotta go out and check it.

Peace of mind

Purchased a whole house "automatic" generator because I live in a very rural, snowy area. I lost power multiple times last winter. I'm ready for anything this winter.
