Over 15,000 completed projects...that is an impressive number. It is the amount of on-the-job experience J.E. Johnson has gained since 1979. This experience has led to the knowledge, skill and insight to provide comprehensive mechanical services and solutions. From a single trailer in Midland to a Midwest Based contractor serving the commercial, industrial, institutional and medical markets, we have expanded where we do business and how we do business.

Since that time, J.E. Johnson has become a Complete Mechanical Contractor, offering mechanical, plumbing, sheet metal, Design Build, engineering, and building control and energy management systems. This one stop shop approach has proven to reduce costs, inefficiency and aggravation for our customers.


MidMichigan Health has used J.E.Johnson on many projects over the years and we find them to be very responsive. Their staff are easy to work with, fair on their pricing and get the job done!
