I called Colorado Discount Heating and Cooling because something was wrong with my furnace. Their technician came out and cleaned it up real good. Apparently, one of the sensors was really dirty which was causing the problem. All is good now. Great job. The guy was friendly and quick and efficient. I ended up signing a service plan with him to come out annually to do the required maintenance on the unit. They have very competitive prices and I would recommend them to others.
