Rated 4 out of 5 by from Quiet generator I haven't needed the generator yet but we're only in the first week of hurricane season. It's nice to hear the weekly test take place, even if you have to go outside and stand by the unit to hear it run. So quiet you can't hear it run from inside the house.

Rated 5 out of 5 by from Great to have From start to finish, this company was great. I have no complaints and all of our needs were promptly addressed. For appearance I rated it lower because it takes up a lot of space in my back yard, but when we're without electricity, I will appreciate my new Generac

Rated 5 out of 5 by from Great Generator We are very happy and completely satisfied with this generator. Absolute peace of mind. Quiet, reliable and automatic. We have had this generator almost a year and it has been 100 percent reliable. When the power has gone out, we were completely and effortlessly protected. Everything in the house was powered. It is so quiet that we have had a hard time knowing that the power grid was down. My neighbors are amazed how quiet it is. No more concerns when ice and thunder storms approach. The green status light on the generators digital display is a constant reminder that we are protected.

Rated 5 out of 5 by from Very satisfied I thought that I waisted my money until the first power outage. I'm very pleased at what I did. And so was my wife, which is important.

Rated 5 out of 5 by from You will appreciate this investment once your power goes out At first, we thought the cost of installing this unit was extreme, however, once the power went out the very first time, you come to realize that it was worth every penny spent, Definitely worth the investment to our property. Thanks to Steve and his crew, they did a very good job installing the unit.
