Founded in 1994, Intermountain Heating & Air Conditioning  has offered quality service and products in the Helena area since the beginning. Brian and Debbie Patzer launched the company to provide a wide range of HVAC systems to residential and business customers in southwestern Montana. As new technologies came to the industry, they embraced energy efficient models that provide comfort through the region’s extremely cold winters and hot summers. The company offered Trane products due to the excellent reputation they have. Their son, Keven, became a part of the business from the beginning, learning from his parents and watching the company grow. When Brian and Debbie decided to retire in late 2016, Keven and his wife, Heather Stipcich, took over day-to-day control.

Intermountain Heating & Air Conditioning is the only authorized Trane dealer in the Helena area. This gives Intermountain's customers the advantage of contacting a company with a strong, positive record of service when they plan to install Trane's outstanding climate control system at their home or place of business. All initial consultations include an assessment of the present building's condition as well as the best way to provide proper heat and cooling levels. Regular maintenance and emergency repair service are also available through Intermountain. When called out, the technicians will offer their diagnosis and the best remedy possible. As a family owned company, Intermountain grew by serving its neighbors in southwestern Montana. That tradition continues to this day.
