G+S promptly responded to an e-mail sent asking if they had qualified techs to work on boilers. In no time, a G+S technician, Toby, came out and checked our gas boiler for us. He was able to get it up and running with just a service call. I was pleased that G+S was able to work on boiler systems, where some other local compnaies did not. Our neighbor also had great things to say about G+S and their professionalism. The technician was prompt, courteous, and proficient, and I was happy that my boiler was fixed before the cold snap kicked in! I also liked that their invoices had coupons for future service calls.
