Rated 4.9 out of 5 by 128reviewers.
Rated 5 out of 5 by Working flawlessly I Have had it for over a year now and it just sits there quietly until it's called upon when the power goes out. Then it turns Into a power pumping monster without hesitation.High winds a few weeks back blew a tree over the powerlines and the they snapped.Within 20 seconds my Generac was up and humming.Easily powering my home.And, it kept on running for the next 6 hours with out any issues.Once the power company had made the repairs and juiced up the lines again the generator quietly and automatically went back into hibernation until next time.And there will be a next time. But I'm not worried.One of the best investments for my family and my home.I'm glad I purchased it. April 8, 2016
Rated 5 out of 5 by Cottage Generator We've had this generator for just over a year. It's very reliable especially when paired with Mobile Link which sends a text when it's testing or when power is out at our cottage. Also, it's easy to find firms who will perform the annual maintenance service.Wouldn't hesitate to recommend. April 6, 2016
Rated 5 out of 5 by Whole house back up gives us peace of mind We just had our generator installed. Jay and Charlie were very professional and had it installed in about 6 or 7 hours. Has a nice appearance to it and doesn't take up much room. Kicks right on when the power goes out. All lights and heat went right back on within about a minute.Very glad we invested in one - it's worth the peace of mind. March 28, 2016
Rated 5 out of 5 by Love this product This is a wonderful system. My 90 yr old mother lives withme and the main reason for getting the generator. I nowhave total peace of mind that we will have power and shewill be safe. Couldn't wait for a storm to come and have thepower go off. March 23, 2016
Rated 5 out of 5 by Excellent product and installation This generator is works well and as promised. Fits nicely into its surroundings. The installation was as promised and the quality of work was excellent. March 15, 2016
Rated 5 out of 5 by This unit far exceeds expectations I was given a time of 9am to 11am for arrival. They were backing in my driveway at 0900 on the dot. Jay and Charlie were amazing. Constantly working and very friendly. They answered all my questions!!!! Wish more service people would follow suit. March 9, 2016
Rated 5 out of 5 by New Installation I replaced a 15 year old generator with the 11 KW and so far have been very impressed. February 1, 2016
Rated 5 out of 5 by Very happy with my new Generac! I purchased the Generac Guardian 11kW whole house generator with one power management module, and a whole house switch. I love it! The power's gone out several times since the install, and it has had the lights on in ten seconds flat every time! Amazing! It's quiet, attractive, and so far very reliable. January 25, 2016
