Mountain Heating & Cooling had originally installed the furnace in this house. Since I bought the house and moved in I figured that I would use the same company for a service call. So this was actually my first time trying Mountain Heating & Cooling and I definitely would recommend them to others. Using them was a very positive experience and they handled the work in a timely manner. The technician, Nick, was satisfactory and very professional. I think the company's pricing is pretty standard and in-line with other outfits that do this type of work. I would use them again for service since they were very good and finished in a timely fashion.
