Over 38 years ago, a small, but dedicated, and forward-thinking group of four combined their years of industry experience and founded Mechanical Systems, Inc.

Even before we had a building, we had a strong foundation around our values—and though a lot has changed since those early days, our values have remained the same: safety, timeliness, integrity, quality.

As a testament to our quality, we are proud to have received the Small Business Administration Regional Prime Contractor of the Year and twice selected as Cheyenne Business of the Year. Over the past four decades, we’ve completed mechanical and utility projects of all sizes and in all sectors, including education, large commercial, institutional, governmental, light industrial, and multi-family.

Though we’ve grown to become the largest locally owned and operated mechanical/utility contractor in the state, we still think of ourselves as that same humble group from 1984—and we’re ready to put our years of industry knowledge and expertise to work across the region.


We work hard and we work safe, always looking out for each other and strictly adhering to our safety policies and industry standards.


We complete projects on time, every time.


We do what we say, and we do what you expect.


Quality is the signature of what we do, and we stand behind our work long after the project’s complete.
