I wouldn't trust my system with anyone but Intermountain Heating.
Darren came to the house at the appointed time and was very courteous and installed the unit in a timely manner. It looks good it's operating good and I'm in the process of learning how to control the thermostat. I might have to get a little coaching on that but otherwise it was all very professional and made me feel like they really cared. I will have no problem having them do work in the future. Very professional and courteous

Intermountain was the HVAC contractor on our new home. Superb support during and after the installation. Refreshing to find this level of service in our area. Highly recommend....
The crew (Jack and Shane) did a remarkable job of installing our Trane heating system. The system was complex due to bedrooms and bath on an upper level. However, they installed heat to all rooms in a very efficient way. They completed the job in 4 days instead of the planned 5 days. They were courteous and left my house clean of any debris. I highly recommend Intermountain and especially Jack and Shane!
These guys go above and beyond!! Can't say enough about this company! Their products are top notch as well! Update, all these years later and they are still 5 stars. You guys have the best crew! Thank you!!!
