I recently used Mountain Heating & Cooling to do some work on my water heater and I was very happy with how everything turned out. The staff was very professional, friendly and easy to work with. I would rate their service five stars across the board. I hired them to help change the thermocouple on my water heater and they did a great job. I didn't have any issues with the staff and the process went smoothly. I would definitely recommend the company to other people based on their efforts.
