Michigan's boiler experts since 1974.
A manufacturer's representative and distributor serving Michigan in sales, service, and parts distribution for commercial and industrial boiler and boiler-room equipment.
Five decades of Michigan boiler rooms
D.J. Conley Associates was founded in 1974 as a partnership with Cleaver-Brooks, one of the most established names in industrial boiler manufacturing. Over the following decades it grew from an equipment representative into a full-service operation covering new equipment sales, factory-trained service, OEM parts distribution, and energy-recovery systems.
In October 2025, D.J. Conley relocated to 26225 Sherwood Avenue, Warren, Michigan, where it serves Southeast Michigan directly as an authorized Cleaver-Brooks representative, and the rest of the state through our other represented manufacturer lines. Ownership has changed hands three times over five decades, and second-generation owner Mike Conley stays on as an advisor. The day-to-day commitment to local, factory-trained service has not changed.
“A primary key to success is to sell products that are quality built, backed by responsible manufacturers, with service and parts support available for the life of the product.”
