We have only had Generac backup generator a few months. During that time we have had some power outages. The power went out and within 5 seconds Generac back up generator started and ran just as promised until the power returned (close to an hour). We are reminded of the Generac's presence every 3 weeks when it tests itself by starting up and running for about 5 minutes. That is a reassuring sound!

After building our new home on the South Texas coast and installing our new Generac with automatic start, we moved in in May 2017. Three weeks later, a huge storm hit and our entire town lost power. Needless to say, we were the only house on our street with power and, thank goodness, air conditioning. Our Generac was worth every penny -- we're so glad we installed it from the beginning!

The installation was a fire and mechanical hazard. 1. Putting the garage door down ripped the wires down causing the door to get stuck. 2. The garage door spring cables rubbed on the power lines - creating a fire hazard. The installation is being redone. I may change my review after the problems are corrected.

Living where power goes out often, it is much easier going to sleep or leaving home knowing this machine has my back. It does it's routine check once a week letting you know it's fine and has a green light that lets off a soft glow I check for out my window before turning in. A great investment.

The Unit Has All Works Just Like Promised. Every Week Is Goes Into It's Test Phase. Runs About Ten Minutes. Then Cuts Off. Shows On The Controls If Any Thing Is Not Going Right. I Strongly Suggest If You Live In A Storm Pron Area That You Get One Of These. I Have The Generac 22KW. I Can run My Whole 23,000 Sq Foot. House Pulse Part Of The House Next To Me. If You Have Propane Or Natural Gas This Is The Way To Go. (Gas Stations Run Out Of Gas Fast And Are Vary Hard To Get Gas To Them. when you get A Heavy Storm.)

We've had the unit a couple of months and it has performed as advertised, we had a couple of power outages of 1 to 2 hrs each and the unit came on and switched to backup power without a hitch. A nice feature is the generator has a self test mode running once a week for 5 min so you know your generators ready to go in case of power outage. Would recommend to all.

The unit has responded on one outage and worked just as it should. The power automatically came back on generator power and everything worked in the house. It only took a few seconds for it to come on and it cycled right off when power was restored from the grid.

The general speaks for itself I'm enjoying it very much when the power goes off I can continually enjoy my day at home whether it cooking cleaning or whatever I do t have to sit around and wait for power to come back on and great features to keep everything running in your house. Thanks Generac

Great product. Once a week it tests itself and let's me know that it is ready to run when I need it. I have full sense of security knowing that when I am away that my food will be kept cold and my basement kept dry. When I am home I have light and my water pump works. This is a piece of equipment that I renamed to anyone who needs electricity 24-7.

This is our third GENERAC generator purchase in a third home place. The first two were installed at two family homes after Hurricaine Katrina. We experienced that first hand, late summer in Central Mississippi. We had a handicapped family member that suffered seizure but worse with heat. Since that time we have had no disruptions to power. Keep them serviced and they have provided years of service.
