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.

Rated 5 out of 5 by from 27KW QS Protector The 27kw QS Protector was installed at our mountain home approx 2-months ago. We have not had an outtage but the unit exercises every Sat. am and with Mobile-Link, we are informed when it starts, finishes and is again ready for back-up operation. In the initial testing, it powered the 4bed 3 1/2 bath home with 2 heatpumps and spa with no problem. This is a very powerful generator. It took me longer to prepare the location, get the big propane tank installed than the single day of installation, hook-up, and check-out. It works exactly as advertised and very happy with the purchase and piece of mind that it brings us when the snow starts to drop. Now we don't hurry quite as fast to get off the mountain. No worries. Thank you Generac!

Rated 5 out of 5 by from This product delivers power when needed. This generator is essential for those of us who live in remote places where power sometimes is interrupted without warning. It kicks in promptly and powers the entire house.

Rated 5 out of 5 by from Peace of Mind We have had two power failures since our generator was restored without it affecting our lives. Performs as expected. Definitely recommend although make sure you get a qualified company to install as the installation is probably just as important if not more than the product.
