I thought that the people at Dial One Schilling were very responsive to my needs. They were very knowledgeable and quick to respond when I had a problem that needed to be fixed. I'm very happy with the company Dial One Schilling and its personnel. The heater wasn't coming on when it would and Scott the furnace man figured out what the problem was and corrected it. He did have to come back out and fix it. The heater wasn't working right for a week so he came the same day I called. I would definitely recommend Dial One Schilling.
