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.

Note: Freon questions are not handled through this agency. Please contact the Stratospheric Ozone Hotline at 800-296-1996. Note: Calls regarding auto mechanics or auto mechanic licenses are not handled through this agency. Please contact the Secretary of State at (517) 373-9060.

Notice: Boiler Licensing for a Residence
Recent amendments to the boiler law have resulted in a long awaited change. The boiler law no longer regulates licensing of individuals who install or repair boilers in a private residence or apartment building with less than 6 families. By default, the licensing of individuals doing boiler installation or repairs in these locations falls to the State of Michigan Mechanical Division. You may refer to the Forbes Mechanical Contractors Act, section 338.977 Sec.7.(1) of PA 1992 of 1984, by linking below.
