The People and History Behind Encode Corporation


Proudly serving Billings and surrounding Montana communities with dependable HVAC, commercial systems, and digital controls backed by decades of local experience.


Serving Montana HVAC Customers Since 1978

Encode Corporation was built around the idea that heating, cooling, and building systems should be supported by people who actually understand the long-term needs of Montana homes and facilities. Public business records trace the company’s roots back to 1978, and the business later expanded under Dennis and Janet Massey after their acquisition in 1984, creating the foundation for the second-generation company customers know today. Over the years, the company developed a strong reputation across Billings for residential HVAC service, commercial and industrial HVAC support, maintenance planning, and digital controls integration that helps businesses manage complex systems more efficiently. Today, customers continue working with Encode Corporation because they want a local company with proven staying power, direct accountability, and practical experience built through decades in the field.

Our mission is to provide reliable HVAC and building-system support that helps Montana homeowners and businesses feel confident, informed, and taken care of when comfort and system performance matter most.

Long-Term Reliability

Customers deserve a company that will still be here years after the installation or repair is complete. Our long-standing presence in Billings helps clients feel confident they are working with a team committed to lasting relationships instead of short-term transactions.

Clear Communication

Heating, cooling, and controls issues already create enough stress without confusing explanations or unclear timelines. We focus on direct communication so customers know what is happening, what comes next, and how their systems are being supported.

Responsive Service

Waiting too long for HVAC help can quickly disrupt homes, businesses, and facilities across Yellowstone County. Encode Corporation prioritizes fast scheduling and responsive support designed to keep downtime and uncertainty to a minimum.

Commercial & Industrial Capability

Large facilities and more complex systems require a different level of planning and operational understanding. Our experience with commercial HVAC, industrial environments, and digital controls helps customers manage systems more efficiently and confidently.

Family Ownership

Customers often want to know who stands behind the work being performed in their homes or buildings. Second-generation family ownership creates direct accountability and a more personal connection to the communities we serve.

Proudly Rooted in the Billings Community


Encode Corporation has supported homeowners, businesses, property managers, and facilities across Billings and surrounding Montana communities for decades. Our work regularly takes us through the Heights, West End, Lockwood, and neighboring areas where changing weather conditions, aging systems, and growing commercial needs require dependable HVAC support from a team familiar with the region. We also continue supporting customers in nearby communities including Laurel and Columbus, along with larger commercial and industrial service relationships extending toward Livingston and Miles City. Long-term customer relationships remain a major part of how the company continues to grow, with many clients returning because they value consistent communication, dependable scheduling, and practical solutions from a team they already know.
