Never setting out to be the biggest, but the best.

It all Started with Jack and Darlene

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.

Despite his long and successful career at Lennox, Jack felt a calling to take his skills to the next level and start his own business. With a passion for helping others and a desire to make a positive impact in his community, he founded Bull Mountain Heating & Cooling in Portland.

Bull Mountain Heating & Cooling is a full-service HVAC company that offers a wide range of services, including installation, maintenance, and repair of heating and cooling systems. Jack’s team of highly trained and experienced technicians is dedicated to delivering high-quality services to their clients, and they take great pride in their work.

In addition to providing excellent services, Jack and his team are committed to building strong relationships with their clients. They take the time to listen to their clients’ needs, answer their questions, and provide expert advice to ensure that every client is satisfied with their experience.

Jack Hansen’s experience, dedication, and passion for the HVAC industry have made Bull Mountain Heating & Cooling a trusted and respected name in the Portland community. With his company, Jack is striving to make a difference in the lives of those he serves, one heating and cooling system at a time.
