The State of Michigan requires that all air duct cleaners must be certified by the state to clean air ducts. Anyone who accesses commercial or residential ductwork must have a category 3 mechanical contractors license to clean your air ducts.
The dedicated staff of the Bureau of Construction Codes (BCC) work as a team to assure that the built environment and the systems within are sound, safe and sanitary; building users’ health, safety and welfare are protected; and that, through a coordinated program of code compliance, investigation and training, there is consistent application of standards.
The Mechanical Division is responsible for issuing mechanical permits, the examination and licensing and renewals of licenses of mechanical contractors and inspections of mechanical installations and repairs. The division also provides staff support to the Board of Mechanical Rules and handles code questions –i.e., furnaces, HVAC (heating and air conditioning), duct work, solar heating, refrigeration and underground tanks.
