CUSTOMER REVIEWS

Rated 4.8 out of 5 by 237 reviewers.
Rated 5.0 out of 5.0 by This Product brings peace of Mind! After 2 storms, I am glad to say I finally invested in a Generac. The 20KW does the entire house and I have a lot less worries! It starts up every Sat AM for its weekly run, and has not skipped a beat. I highly recommend the Mobile Link to receive Text Messages on how your system is doing. April 10, 2015
Rated 4.0 out of 5.0 by low maintenance, reliable back-up other than changing the oil, there isn't much to do but stand out of the way and let the generator do it's thing. the unit isn't loud, but more noise insulation in the cabinet would always be a good thing (for any unit). March 27, 2015
Rated 5.0 out of 5.0 by Excellent peace of mind I just had this generator installed. We live in the country In Iowa and have a gas furnace and well for water. The winters here can be brutal. I can't begin to tell you how much peace of mind this equipment provides. I can rest easy now when I am out of town and not worry that my wife has any concerns with heat, water, the security system or anything else that is dependent on electricity. The system is awesome. It checks itself on a weekly basis and is very simple to maintain. This is probably the best investment I have made for our home. December 16, 2014
Rated 5.0 out of 5.0 by product fits well with most landscaping we had just finished installing our unit and wouldn't you know it there was a power failure and allbeit a very short one it was long enough to have the generator kick in automatically and run longer in cool down stage than protection stage, but still i think it will be worth it in the long run we have had several outages in the past so here's hoping. we also purchased the whole house smart switch for added comfort and protestion Eric December 17, 2014
Rated 5.0 out of 5.0 by should of bought one yesterday dont put it off generac the one only to have in case of power outage the life saver. December 17, 2014
Rated 5.0 out of 5.0 by excellent unit to have i live on a mountain bluff on a dead end road at the edge of the electric utility service region, well outside of any town or city. power outages are not unusual. this unit is reliable and quiet and works like a charm. it was a part of our going in plan when we chose to build in this location and i'm glad to have it included. would do it again and would recommend it to other to consider. November 6, 2014
Rated 5.0 out of 5.0 by Better than 5 stars!!!!! We had our Generac 20kW and whole house switch installed in March 2014. Ever since the install we have been hoping for the power to go out (strange yes but wanting to test the investment). Finally the power went out during a thunderstorm Sept. 1st. The generator started confidently just like it does on it's weekly exercise runs. We were so pleased that we did not need to drag out the old portable generator. During the 6 hours of outage we ran, 3 TVs, 3 computers, the dishwasher, the AC, 2 fridges, 1 freezer, the sump pump, the well pump, the garage door and almost every light in the house at varying times. The Generac never missed a beat and was so quiet when it was time for bed nobody complained like they did with our old portable. Fantastic product. Exactly why my parents and in-laws installed their's a few years ago. September 2, 2014
Rated 5.0 out of 5.0 by Awesome! We had this unit installed and within 2 weeks the power went out for approx. 7 hours. Would have thought it just blinked off then back on thanks to this generator. Love it! Worked like a charm. Could not be happier! September 10, 2014
