Rated 4.8 out of 5 by 91 reviewers.
Rated 5 out of 5 by Good price, acceptable quality I am electrician and we have installed more than 100 in less than a year, I like the performance, virtually dot have to do anything, just change the oil. It is true that we have taken some mechanical problems with some, but in general I like. I recommend it. November 5, 2012
Rated 5 out of 5 by 10kW Automatic Home Standby Generator I am an electrical contractor. I do not install standby generators but wanted one for my own home. I did extensive research on most models. I did see a few bad reviews on Generac generators but I also saw they sell more than the other manufacturers combined. I liked what I saw on their specifications, looked at one at Home Depot and liked what I saw. Home Depot also had the best price so this is what I bought (as I am a retired vet I received a discount) . Installation was straight forward and easy for me. I believe most people who are handy, and follow the code can install one themselves. If necessary you can always have a licensed electrician check your installation. I checked with the gas company and they installed a larger gas meter, no cost, to handle the extra load. I have only tested the generator so far, no power failures yet, and am happy with my purchase at this point. February 19, 2011
Rated 5 out of 5 by Very quiet! We chose tholis model since is is SSSOOO quiet. In "test" mode, I have to go outside to be sure it's running. Even on generating mode, it's not much louder. Vey nice machine. June 17, 2014
Rated 5 out of 5 by Worth its weight in gold! We live in a rural area that loses power a couple of times a year. The last time we lost it for 4 days, with the power coming back on Christmas Eve. When we lose power, we lose more than just lights, heat, we lose water, and sump pump power too. If we are home, we will have power, if we are gone, we don't have to worry about the basement flooding. It blends in with the house, does not stick out like a sore thumb. Love seeing it sit there with the green light on! The generator not only gives us power, it gives us peace of mind too. May 14, 2014
Rated 4 out of 5 by Just had my Generac installed and hope to not have to worry about not having electricity anymore. We have worried for the past 12 years when it rains too hard or the electricity goes out since our sump pump runs almost constantly. Now we can have peace of mind when we are at home or on vacation.
