First time working with Colorado Discount Heating and Cooling, everything went very smoothly. My house is very old and didn't come with a central heating system, things are starting to get a little too cold for me so I decided to get some quotes from some companies around the area for a new heating system. Colorado Discount had the best prices and they really provided me with great customer service over the phone. We were able to schedule some dates that would work for us to get the job done and they got the job done in about a week. The heater is working but since my house is very old it doesn't retain heat very well. Overall very good experience.
