O'Brien's Plumbing service was excellent. They replaced my old boiler with a new more efficient unit. They even walked me though the Mass Save rebate process. The technician, Brian, that came to the job was very professional and extremely knowledgeable. I would highly recommend them.Service: Water heater installation
