In Michigan, performing heating, ventilation, air conditioning, and refrigeration (HVAC-R) work for the public requires a Mechanical Contractor license. This license is issued by the Michigan Department of Licensing and Regulatory Affairs (LARA) through the Bureau of Construction Codes (BCC). This guide provides a comprehensive overview of the licensing process, from understanding the specific classifications to meeting renewal requirements.
Do You Need a Mechanical Contractor License in Michigan?
If you or your business intend to contract with the public to install, alter, or service mechanical systems, you must hold a Michigan Mechanical Contractor license. This requirement applies to a wide range of work, including heating, cooling, ventilation, and refrigeration systems.
Understanding Michigan Mechanical Contractor License Classifications
Michigan’s licensing system is specific, requiring contractors to qualify for the exact type of work they plan to perform. Instead of a single "HVAC" license, the state issues a Mechanical Contractor license with several distinct classifications.
Classifications of Mechanical Contractor Licenses:
- Heating (A): Covers forced air heating systems, including those with or without attached cooling, and ventilation systems.
- Refrigeration (B): Pertains to refrigeration systems, including refrigerators, freezers, and cold rooms.
- Hydronic Heating and Cooling and Process Piping (C): Includes hot water and steam heating systems, chilled water cooling systems, and piping for conveying liquids or gases for processing.
- Ductwork (D): Focuses on the fabrication, installation, and alteration of duct systems for ventilation and air conditioning.
- Gas Piping (E): Authorizes the installation, alteration, and servicing of gas piping systems from the gas meter to the appliance.
- Unlimited Service (F): Encompasses the servicing of all mechanical systems covered by the other classifications.
- Limited Service (G): Pertains to servicing specific types of equipment, with the scope defined at the time of licensing.
Michigan Mechanical Contractor License Requirements
To qualify for a Mechanical Contractor license in Michigan, all applicants must meet a set of baseline criteria for age, education, and professional experience.
General Eligibility Criteria:
- Be at least 18 years old.

This experience must have been gained while working under the supervision of a licensed mechanical contractor. You will need to provide detailed documentation and an affidavit from your supervising contractor to prove your experience.
Federal EPA Section 608 Technician Certification:
Any contractor or technician who maintains, services, repairs, or disposes of equipment that could release refrigerants into the atmosphere must hold an EPA Section 608 Technician Certification. This is a federal requirement separate from state licensing. Certifications include:
- Type I: For small appliances.
- Type II: For high-pressure appliances.
- Type III: For low-pressure appliances.
- Universal: For all types of appliances.
The Application Process for a Michigan Mechanical Contractor License
The application process requires careful preparation and submission of all required documents to the Bureau of Construction Codes.

Insurance and Bond Requirements for Michigan Mechanical Contractors
While Michigan has specific state-level licensing requirements, insurance and bonding are often determined by local and contractual obligations.
General Liability Insurance:
It is standard business practice for all contractors to carry general liability insurance to protect against property damage and bodily injury claims. Coverage amounts often vary based on the size and scope of your projects.
Workers' Compensation Insurance:
If you have employees, you are required by Michigan law to carry workers' compensation insurance. This covers medical expenses and lost wages for employees injured on the job.
Surety Bonds:
While not required for state licensing, project-specific payment and performance bonds are common in the construction industry. Some sources mention a potential $5,000 surety bond in specific situations, which should be verified based on your scope of work and location.
Renewing Your Michigan Mechanical Contractor License
Maintaining your license requires timely renewal and completion of continuing education.
Renewal Cycle:
Michigan Mechanical Contractor licenses must be renewed every three years.
Continuing Education (CE) Requirements:
To renew your license, you must complete 6 hours of approved continuing education during each 3-year renewal cycle. These courses must cover topics relevant to the mechanical trade, including code updates, safety, and business practices from a state-approved provider.
Michigan Mechanical Contractor Reciprocity and Endorsement
Michigan's approach to out-of-state licenses is limited, and there are no broad reciprocity agreements.
Current Reciprocity Status:
Michigan does not have any blanket reciprocity agreements with other states for Mechanical Contractor licenses. All applicants must meet Michigan's specific experience and examination requirements.
Endorsement Review Process:
Out-of-state contractors may apply for a license and have their experience and qualifications reviewed by LARA on a case-by-case basis. However, passing the Michigan-specific exam is typically required.
