When Colorado Discount Heating and Cooling came over to service my heating unit, they were very timely and they cleaned up after themselves. The guys who were there were very personable and answered all my questions. They also followed up and did a check-in with the unit after the servicing to make sure everything was OK. We haven't had any issues since they fixed it. I will use them again if any other issues come up, but this was my first time. The price was fair. It was within the normal range of what the unit would cost. I would recommend them, I think they did a great job.
