Jack Hansen’s 31-year tenure at Lennox gave him a wealth of experience and knowledge about the HVAC industry. He was a dedicated and hardworking Service Engineer who was known for his commitment to providing the highest level of customer service. Over the years, Jack developed a deep understanding of HVAC systems and their components, as well as an ability to diagnose and repair even the most complex problems.

In 2003, he decided to branch out on his own and started Bull Mountain Mechanical, with his wife, Darlene and son, Brian. It started as a commercial only HVAC business but quickly found success in the residential market because of the dedication to quality, customer service and honesty.

Now known as Bull Mountain Heating & Cooling with over 20 years in business, it has become a staple of the community, providing great service for not only the city Brain grew up in, but all over the Portland Metro area. 

In early 2024, Brian purchased the business from Jack and Darlene, allowing them to retire. Bull Mountain continues to be the same customer focused, high quality, honest business that him and his father started. 

The third generation is now growing up, learning about the industry and sweeping the shop floor on the weekend.
