GenReady, Inc.
GenReady, Inc.
Gen Ready, Inc., was established in 1979 to service the surrounding area and provide residents with all their standby electric power solutions. Our staff of knowledgeable and dedicated professionals take pride in providing outstanding, personalized service to our customers and our community. All of our techs are factory trained and certified for warranty repair and maintenance. Call us today and become one of our many satisfied customers. You can visit us online at www.getgenready.com
"After getting several quotes, last year we hired GenReady to install a house generator. Ed, the owner of the company impressed us from the start. He was knowledgeable and patiently explained the process as well as answering our questions. We knew right away that GenReady was the company for us. Lindsay kept us up to date as we moved along in the process. Our generator was installed last July. Andrew and his team installed the generator with expertise and efficiency. They took care to leave our house and yard spotless. Lindsay and Andrew were always happy to answer my questions and address me concerns. We’ve needed the generator only once (thank goodness) when our power went out due to a necessary power line repair after a car crashed into a utility pole on our street. When the power went out, our generator turned on within seconds. Our house was up and running for the four hours the line repair took, and if it weren’t for the blink of lights, we never would have known our generator was running. Every other week, our generator self tests for a few minutes giving us peace mind that it will be here for us if and when we need it. Just like the generator, GenReady is a company that runs efficiently and seamlessly. Just today, Lindsay called to tell me someone would be coming tomorrow to change the oil which reminded me that I am long overdue in submitting this well deserved rave review. Thank you to the entire GenReady team (and to Great White Propane) for all you’ve done to help us know we can weather any power outage."

"I used stone to upgrade the electric in my house and connect my hot tub and pool. The crew that came to my home were good... But if you have a question about something Sean is nowhere to be found. You have to go thru the secretary who is absolutely clueless to ask a question. The only time you see Sean is when he comes to your house for the estimate. After that he is unobtainable. When you call in the morning with a question your lucky if you get an answer by the end of the day or the next day. I found them to be overpriced, rude and even nasty at times. I would never use them again"
