Rated 5 out of 5 by from GenerxGenerators Super happy with the newest member of the family! From start to finish, the Generx Team delivered as promised to afford peace of mind should we loose power. With the many storms that seem to be in the horizon, we have assurance that our system will keep us up and running. I am certain that the investment will be worth every cent and more. Thanks!

Rated 5 out of 5 by from Very excited and relieved to have it! My father owned a full home generator (Generac). I experienced the peace of mind it gives you when Hurricane Matthew came through. It never waivered. It ran for 3 days while the neighborhood was without power. We even let the A/C run. No issues! We were very content. I now have my own home and just had the Generac installed this week. I am so very thrilled to have it and look forward to the weekly schedule where it will start and run for 5 mins every Sunday! It did yesterday and I was like HELLLLLO Jimmy-Rac. I named it after my father.

Rated 5 out of 5 by from Excellent Generator We did a lot of research on standby generators and decided on the Generac 22kw. At first, we weren't so sure Generac was the brand for us. There had been a number of complaints. Our dealer explained that early on the Evolution control board was failing. But the issue was resolved. We took him on his word and glad we did. Four days after it was installed, the Seattle area was hammered with over a foot of snow and power went out. Generator kicked on and stayed on for the next 10 hours. Power was restored for around 3 hours and went back out. Generator kicked on and ran for another 12 hours. We rely on a pump grinder to discharge sewage. Without power, we get 10 flushes from our toilet. Wife demands that system work! So far, Generac has made us a believer. We live on a island and the other thing that sold us was parts are plentiful. Not so much with other brands. The free mobile link is nice but highly limited. To get full use of its features you have to pay a monthly fee. We highly recommend this generator.
