I used this company to install a boiler in October of 2007, it was, and continues to be a huge headache. They failed to spec out the project properly and they failed to install the boiler correctly. After repeated calls about heat problems, they finally figured out the problem, but it took several months, many hours of phone calls and research on my part to identify what the problem is (and which they ackowledged was correct), and when all was said in done, the heat still worked oddly. Now, one year later, I realize why. They did not even install the thermostats correctly. With all that said, I must admit my heating system is working correctly now, but the time, pain, and energy I had to invest to get it right was definately NOT worth it. There are many contractors out there - choose someone else.
Pros: Good price
Cons: Ridculously incompetent
