I've used Benjamin Franklin Plumbing & Minuteman Heating and Air on various occasions in the past, and although I think they're a little bit expensive sometimes, their service is typically good. They were last out to install a new thermostat, and although I was pleased with their work, we didn't get to discuss how to use the smart thermostat. I did let them know that I had the instruction manual and that I could go through it and figure it out on my own, but I do wish we had gotten the chance to go through the functions together. It's been around ten years since I've started using them, and overall their techs are very professional, and they do good work. I plan to continue using their services.
