Very happy with the install
I called three different contractors for our planned installation of a Generac full house emergency generator. Kelley Brothers impressed me at the walkthrough and quote more than the other two. Arthur was patient and thorough with me. He answered all my questions and concerns. We decided to go with Kelley Brothers for the install. Everything was done in a timely and efficient manner. We are very happy with the install and look forward to many years of service from our Generac emergency full house generator. Thanks to all the people we dealt with at Kelley Brothers for making this a pleasant experience.
