Product Reviews

  1. Cost Effective Peace of Mind

    Posted by Peter P. on 24th May 2014

    Installed the 20RESA 8/13. Had a very cold and snowy winter in this area of NJ. The unit responded perfectly on each outage - at least 4 that I'm aware of. Noise level was present but acceptable.


  2. Great design

    Posted by Unknown on 29th Apr 2013

    I attended a Kohler install seminar and these are really built well. Better than the mainstream units. Pay a little more and you get a great product.


  3. A life saver

    Posted by Joanne on 1st Nov 2012

    I've been on this generator for several days now thanks to power loss from Sandy. It has been a blessing to have light and heat in these terrible events on the Jersey shore. I had a few questions and the tech support at Kohler has been terrific. Maintainence is minimal - just check the oil every day and add as needed. One of the best decisions I ever made when I bought this
