I have used Coleman when I replaced my furnace and hot water tank 8 years ago. I also came to them for a A/C purchase and install three years ago. They have been simply outstanding. They have always met their timeline for their work and have made sure that any amount quoted was exactly what I paid. They have made every service call and most recently I made an emergency call as my furnace did not appear to be working. Jeff showed up within half an hour and not only fixed the problem, he showed me what the issue was (a buildup of some dust, etc, that plugged a pipe) and showed me how to fix it myself. He didn't charge for the brief service, despite the fact it was on a Saturday and ensured that the heat was working before he left. I will continue to use and recommend Coleman without hesitation. My thanks to them and their crew!
