Rated 5.0 out of 5 by 7 reviewers.
Rated 5.0 out of 5.0 by This product has great performance! The Generac 36K Quietsource backup generator is a life saver for us. It performs as described, each time and every time. We live in an area where electrical power is not reliable during rain or heavy wind storms. We appreciate the reliability of this product as our home must have electrical power due to a health condition in our family. Thanks Generac! August 5, 2014
Rated 5.0 out of 5.0 by Now ready for electrical power outages.... Never again will I or my family worry about electrical power failures. We lived through several hurricanes in which we were without power for several days. Now we will have internet, phone, satellite, security system protection, air conditioning, refrigerator, freezer, and washer and dryer ability. No more having to pack up kids, grandkids, and pets to travel hours to find a hotel/motel that has power. No more hauling dirty laundry and find ice. Thanks have made my Day! March 17, 2014
Rated 5.0 out of 5.0 by 36KW QuietSource Our generator installation went great. The Generac 36KW looks great sitting next to our house. It was set up to run 1/2 of our house. Hopefully we will not lose power, but if we do we will barely notice. September 23, 2013
Rated 5.0 out of 5.0 by Hurricane Ready in Louisiana! Installed 36kw Quietsource upon completion of new home in South Louisiana. Its not a matter of "if", but "when" we have a prolonged power outage, we stand strong and ready. It's weekly exercise run is so quiet! Family safey and comfort is extremely important and our Generac is the proudest possession of our home. We have lived through several hurricanes, but will never spend 2-3 weeks in 95-degree Louisiana heat again! Thank you Generac! May 3, 2013
Rated 5.0 out of 5.0 by Great Unit We just went thru hurricane Irene and this unit kept everything in my house running like I was on commercial power! My house has two separate meters with 200amps at each; We installed two ATS’s. It took less than 30secs for backup power to turn on. I ran my 5ton AC unit, 3ton AC unit, all the lights in the house, electric oven, dishwasher, TV’s, Computers, 2frigs and 2ice chest freezers. I can’t tell you how impressed I am with my 36kw unit. It was not that cheap, however it is worth every penny!!! August 29, 2011
Rated 5.0 out of 5.0 by Never New It Was On I have had nothing but good to say about my QuietSource. We had a power outage just before I came home just before dark. I went in the back door as usual just around corner from my generator. My wife came in shortly after dark and told me that all the lights on the street were off when I realized that we were running under generator power. I could not believe that I never noticed the generator running. March 28, 2012
Rated 5.0 out of 5.0 by Run very quiet. I purchased a 36K. I give it 5. Hurrican Isaac was the first time I experience it in full service. It ran great. September 2, 2012
