The original goal of the new company was to become a stronger provider of mechanical services to the residential, commercial, and industrial markets. The vision in 1972 was to earn a reputation for the highest quality of professional work combined with the highest ethical standards.  The goals and visions of MSI have remained the same ever since. MSI's dedicated team offers their customers the exceptional service and knowledge that can only come from years of experience.
