Due to drastic changes in the workforce A.J. Miller Mechanical, Inc. was developed in 2011. We work hard to provide a service that reflects the individual needs for each customer at a competitive and realistic price. A.J. Miller Mechanical, Inc. works primarily in the Commercial/Industrial/Institutional field but does not exclude residential. Our goal is to continue serving our existing clients while expanding to any size necessary and maintain our excellent status as Michigan's elite mechanical contractor.
