Copied from a writen review received from Tamara Hunt on 5/5/11: ""Everyone at BNG was very professional. Mark returned my call for a quote within an hour, and discussed our options with no pressure to buy higher-priced unit. Great guarantees about prices and service. They replaced the HVAC and water heater and had to coordinate with our contractor to work around ongoing basement waterproofing. They even loaned us a window air conditioner during the work! Everything was done on time, and workmen explained the system to us before they left. Then, Carla from their office filled out our Vectren rebate paperwork and mailed it to us in less than a week. Highly recommended!
