When I called Colorado Discount Heating and Cooling they came almost immediately. I was very impressed. My AC went out and they came out the very next day to evaluate the situation. The day after that they installed a brand new AC unit. I was selling house and needed it done immediately, so I was very relieved they were able to accommodate my timeline. They were all extremely professional and very polite. They did exactly what I needed them to do and when I asked them after we had the work inspected to take care of something they came immediate and took care of it free of charge. The price was extremely reasonable in my opinion. Definitely not too expensive considering I have a whole new AC system in place. They were more than willing to take care of my needs as soon as possible. I would highly recommend their service.
