Colorado Discount Heating and Cooling came to look at my furnace and possibly repair it, but it turned out I actually needed a new furnace. They did the installation that same day. Everything was taken care of and they cleaned up after themselves well. The workers were professional and friendly. It was great! I would use their service again. I didn't shop around at the time because I was in a pinch and needed the new furnace, but I think the pricing was pretty fair.
