We have experience on our side.


Our commitment is to provide our customers customized, comfort  and safety solutions for their homes and businesses, centered around top quality products that deliver efficient comfort solutions, all delivered with a focus on craftsmanship.

Since 1977 we have been providing heating and cooling installation and service to Bozeman homeowners and businesses. Ours is a family business so we know that every project we do bears our name and carries our reputation.

Corky and Lois Johnson opened Mountain Heating and Cooling in 1977. We have been serving Bozeman, including the entire Gallatin Valley with pride ever since.

In 2011, the Johnson’s son, Corey and wife Meredith, continued the family business tradition. After 15 years as a licensed architect, Corey’s experience in the design field sparked areas of interest in addition to allowing him to compliment aesthetic design of building envelopes, with function, energy conservation, and building systems design. We focus our efforts on ways to reinforce and retain our core values of customer service and stewardship that is truly ‘client centered’.

We take pride in our team partnering with the best people in the industry.  Our HVAC installation professionals receive 40 hours of technical training annually and are a huge piece of our commitment to our customers. Each technician and company employee is drug and background tested to give you peace of mind and a great experience in your home. 

Every project we undertake receives our “white glove” commitment to excellence. The variety of our experience and project types allows us   to provide a creative approach to solving problems while maintaining the technical requirements of each HVAC system.

Our service technician team of NATE-certified HVACR technicians are trained to get HVAC repairs done right. This means you get the best technicians in your home and business trained to understand comfort systems, resulting quick diagnosis  and repairs when you need it most.  

We will always work hard for you. Call Mountain Heating & Cooling today! You’ll be glad you did. 406-586-4007.
