Rated 4.6 by Our Customers
The service was the best from any of the providers we use on a regular basis. You showed real loyalty to the customers that have annual contracts with you. We called in the middle of our power outage in Connecticut and your very knowledgeable repair technician was at our home in two hours.
Peter F.New Canaan, CTThe power went out and the generator is working perfectly! It is so quiet I actually had to open the door to the patio to hear if it was on or whether it was just a quick outage and the regular power was back on. I am so happy we went with this one. Thank you so much for getting this perfect. I love it!
