Rated 4.9 out of 5 by 85reviewers.
Rated 5 out of 5 by product insures peace of mind I have not had to use this since installation. That is a good thing. The peace of mind that I have while away from home is great. The generator starts and runs precisely as it is scheduled. I view this as an insurance that I only have to pay for once. No more calls that power is out and I have to cut my vacation short and come home to protect my home!Jim February 20, 2015
Rated 5 out of 5 by Generacs are a life-saver when there are power outages! Since the recent installation of my Generac, any act of nature causing a power failure no longer results in leaving me in the dark, without heat of air conditioning, or water in the basement. My Generac creates a sense of security making life calm because everything in my house will continue to operate as usual. Security system, furnace/air conditioning and all other electric items in the house. The peace of mind is more than I can express. Just as now, a winter storm warning in progress…24 inches of snow on the ground and high winds bringing temperatures to -20 to -30 degrees tonight. Generac will do its job in a time of need. Quite a mental relief giving a peace of mind.And, not to forget the installers who worked diligently to sustain and overcome the zero weather the day of installation. They were dedicated and knowledgeable; and completed the job in a spectacular way, always being polite.I would not hesitate one second to recommend a Generac to anyone who would appreciate the same peace of mind I am enjoying!!!

Rated 5 out of 5 by Peace of mind when home and away Purchased a unit that will provide electricity to the entire house when necessary. Last years power outage was the last straw no more dragging out the gas generator and filling it up every 3 hours, the noise and cords to the house. The unit runs smooth without being very noisy. 5/5 year warranty, installation was smooth and done within a day. Should add value to the house for resale years from now. January 22, 2015
Rated 5 out of 5 by Great product! After being out with power for nearly two weeks with Hurricane Sandy, this generator has brought piece of mind. Installation took two days and that was it! January 10, 2015
Rated 5 out of 5 by This product is exactly what I wanted. Your servicemen were courteous and efficient. They were in and out in a few hours and treated us with respect. They were a joy to work with. Thank you very much!Ralph January 6, 2015
Rated 5 out of 5 by Great generator! We put ours in a month after Irene hit the NJ coast in 2011. We lived in a rural area with frequent power outages and we had a well pump. When Sandy hit and knocked our power out for 12 days in very cold weather we were very comfortable.mour 10Kw did the entire first floor well pump, furnace, wood stove blower and master bedroom and bath or a 3,500 sq ft house. We had a 1,000 gallon propane tank for heating, so that generator could go over 30 days. We now live in FL and are going to put another Generac in. December 19, 2014
Rated 5 out of 5 by I like the 11KW generac that we have had just over one year I am very satisfied with our generac generator it has very little noise. and is very reliable . December 16, 2014
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
