How can we help?

What we do

The Mechanical Contractors Association of Indiana, Inc. is a statewide trade association established to represent and service its members in the mechanical industry. It acts as the industry’s voice in dealing with the public, state and local government, other construction industry groups, and labor. Unlike most other trade associations, the primary focus of MCAI is education, labor relations, and multi-employer collective bargaining.


How We Help

MCAI Services Provided

Represents members in all labor relations matters including negotiation, grievances, apprenticeship training and benefit plans; Legislative and governmental affairs representation before state and local bodies; Represents member interests to owners, architects, engineers, general contractors, subcontractors, and others involved in construction; Educational programs are provided to the members and their employees.

MCAI Two Service Bureaus

MCAI operates two affiliate organizations which provide additional services to the mechanical construction industry. Each has separate membership and financing. Indiana Chapter 14 of the National Certified Pipe Welding Bureau (NCPWB) promotes quality welding in the pipe fitting industry at reduced costs through an interchange of welders and development of welding procedure specifications. The Service Contractors Association (SCA) provides assistance to contractors and service managers of those firms involved in H.V.A.C. service and maintenance.

MCAI National Affiliation with MCAA

MCAI is closely allied to its national counterpart, the Mechanical Contractors Association of America, located near Washington, D.C. All regular members of MCAI are also members of MCAA. A large contingent of MCAI members regularly attend the MCAA Annual Convention usually held in March of each year. MCAI has also supported four (4) of its members to become presidents of MCAA (H. Jack Baker, 1974, James A. House, 1990, Steve Dawson, 2015, and Greg Fuller, 2017).

MCAI Local Chapters

Within MCAI there are five local chapters who meet on a regular basis and carry on much of the business of the association. These chapters are known as MCA-Indianapolis Area (Indianapolis, Kokomo, Muncie, Anderson, Richmond Area), Fort Wayne Area MCA (Ft. Wayne, Marion, Elkhart, Angola Area), Wabash Valley MCA (Terre Haute, Lafayette Area) St. Joe Valley (South Bend, Mishawaka Area), and the MCA of Southern Indiana (Evansville, Bloomington Area). Each of these chapters is engaged in multi-employer negotiations and has a current collective bargaining agreement with their respective United Association local union.
