Our technician, Jim L., was very knowledgeable, dependable, friendly, and thorough. He did a great job of installing our boiler in a reasonable amount of time. He showed up when promised and even called to let us know when he was on his way to our house. He and his staff obtained all necessary permits for us and communicated installation progress with town code/fire inspectors. After finishing the installation, he an his staff explained everything we needed to know about the unit. I would highly recommend this company and its staff.
