We recently switched to using Mountain Heating & Cooling because of their quality and reliability. We had used other companies in the past and they never lived up to our standards. I find Mountain Heating & Cooling's pricing to be fair, they arrive on time and get the job done. They recently came to replace my thermostat which was a relief, when you live in Montana you need your thermostat to work. It has been a pleasant experience and I will continue to use their services for the simple fact that reliability is important to me.
