Rated 4.8 out of 5 by 92reviewers.
Rated 5 out of 5 by The features on this product are outstanding. Two days after product was installed we had a power failure and it was great not to have to worry about the furnace, refrigerator, freezer or any other electrical appliance, clock, or lights. This is the best feature that we have ever added to our house and it is great not to have to be concerned about it any more. This product worked just as we were told it would. April 13, 2015
Rated 4 out of 5 by Easy install The unit was easy to instal. If you have basic electrical and plumbing skills you should have no problems.Just waiting for the power to go out now for the real test. March 18, 2015
Rated 5 out of 5 by Top item to own We had one installed when we had the house built. No problems with the unit at all. Two days ago, when it was below zero one night, and ComEd did their usual with an outage, WE STAYED NICE AND WARM thanks to the unit. March 13, 2015
Rated 5 out of 5 by This generator rain or shine-- home or n it will always be their for your needs. THIS GENERATOR IS NOT ONLY A INSURANCE POLICY BUT GIVES ME PIECE OF MIND KNOWING MY BRIDE OF 51 YEARS IS BEING WELL TAKEN CARE OF WITHOUT ME BEING HOME TO DO THE JOB MY 10K GENERATOR WILL DO.Thanks March 12, 2015
Rated 5 out of 5 by New customer - 6 month owner. Have owned my Generac automatic transfer generator for six months. Although we have not had a power outage since its installation (right thru winter), it has performed its weekly 5-minute run without a problem. March 11, 2015
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!!! February 14, 2015
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
