This was the first time I used The Heating Specialist and they did a great job. They installed a new boiler for me and a new hot water tank. Everything is working beautifully. I am very pleased with the job they did. I give them the highest ratings and recommendation. I was treated very nicely when I called requesting service. the serviceman responded very quickly, and I had hot water again. The serviceman was very professional and courteous. I am glad I gave them a call. They have great customer service and very reasonable prices.
