Permit applications must include system specifications, equipment serial numbers, and designer plans for new construction. Replacement units under 50,000 BTU may qualify for expedited permitting. Ductwork modifications require permits. Estimated permit cost: $75-$250 depending on project scope. All work must pass final inspection before system activation.
Inspection Schedule
Initial inspection required before work begins (for permit issuance). Rough inspection after ductwork installation and before wall closure. Final inspection after system startup and verification of proper operation, airflow, and refrigerant charge. Commercial projects may require additional inspections at framing stage.

How to Get Licensed
Document Your Experience
For Class A: Compile 4 years of documented HVAC work history or proof of completion of an approved apprenticeship program (typically 8,000+ hours). For Class B: Document 2 years of HVAC work or apprenticeship completion. Documentation must include employer names, dates, job descriptions, and verification contact information. Keep timecards, pay stubs, and letters from past employers on file. Apprenticeship programs through unions or trade schools are faster paths and automatically qualify you.
Register with LARA
Submit an application to Michigan's Department of Licensing and Regulatory Affairs (LARA) for Mechanical Contractor Licensing. Include your experience documentation, personal information, and proof of compliance with any background check requirements. Application processing takes 2-3 weeks. Filing fees are approximately $150-$200. LARA will verify your experience documentation with listed employers before approving your application to sit for the exam.
Pass the Michigan Mechanical Contractor Exam
Schedule and pass the Michigan Mechanical Contractor Licensing Exam administered by LARA. The exam covers Michigan plumbing and mechanical code, HVAC system design, equipment installation, safety regulations, and business practices. Study materials and sample exams are available through LARA. The exam costs approximately $100-$150 and takes 2-4 hours. Passing score is typically 70%. You can retake if needed; allow 2-4 weeks between attempts.
Obtain EPA Section 608 Certification
Pass the EPA Section 608 refrigerant handling certification exam. You can test for Type I (small appliances), Type II (high-pressure systems), Type III (low-pressure systems), or Universal (all types). Universal certification is recommended for HVAC work. Testing is administered by approved organizations; study materials are available online. The exam costs $80-$150 and takes 1-2 hours. Certification is effective for the life of your contractor license but must be renewed with your license renewal.
Obtain Your Mechanical Contractor License
After exam passage, LARA issues your Class A or Class B Mechanical Contractor License. License renewal occurs every 2 years. You must complete 4 contact hours of continuing education per renewal cycle through LARA-approved providers. Continuing education covers code updates, safety requirements, and HVAC technology advances. Renewal applications must be submitted 30 days before expiration; late renewals incur penalty fees.
Ensure All Technicians Are Licensed
Every technician performing HVAC work must hold a current Michigan Mechanical License (journeyman or apprentice). Apprentices work under supervision of a licensed journeyman or contractor. Have all crew documentation on file and current. EPA 608 certification is required for anyone handling refrigerants. Document all certifications and renewals. Never allow unlicensed work; penalties include fines, license suspension, and liability exposure.
Register with City of Grand Rapids

City registration is separate from state licensure and typically costs $50-$100 annually. Keep current registration documents on all service vehicles. City maintains a list of approved contractors; customers can verify your standing.
About This Market
Grand Rapids HVAC market runs steady year-round with brutal spikes in winter and summer. You've got roughly 2,574 licensed mechanical establishments statewide, but Grand Rapids and Kent County concentrate significant density—enough competition to keep pricing honest, tight enough margins that efficiency matters. Market demand drives on two things: residential replacement cycles (average system lifespan 15-20 years) and commercial maintenance contracts. Winter emergency calls spike hard; frozen condensate lines, ignition failures, and blocked vents keep phones ringing November through March. System replacements run $5,200-$10,000 depending on equipment quality and ductwork condition. Service calls with minor repairs land $350-$850. Median hourly rate for techs sits at $31.01/hr, but a well-run operation bills $85-$150/hour for labor. New construction work is steady but competitive; retrofit and replacement work carries better margins.

Frequently Asked Questions
What license do I need to start an HVAC contracting business in Grand Rapids?
You need either a Class A or Class B Mechanical Contractor License from Michigan's Department of Licensing and Regulatory Affairs (LARA). Class A requires 4 years of documented HVAC experience or completion of an apprenticeship program, plus passing the Michigan Mechanical Contractor exam. Class B requires 2 years of experience or apprenticeship plus the same exam. Every technician performing work must hold a current Michigan Mechanical License (journeyman or apprentice level). Additionally, anyone handling refrigerants must hold EPA Section 608 Certification. Licenses renew every 2 years with 4 contact hours of continuing education required per cycle.
How much does a furnace or AC replacement cost in Grand Rapids?
Central AC replacement (3-5 ton units) typically runs $5,200-$8,500 installed. Furnace replacement (90k-100k BTU) ranges $3,500-$6,200. Heat pump systems (which provide both heating and cooling) cost $6,500-$10,000. These ranges reflect equipment quality, labor complexity, and ductwork condition. Emergency service calls with repairs run $350-$850 depending on repair type. Annual maintenance agreements run $150-$300 per visit. Ductwork installation or replacement costs $35-$75 per linear foot. Prices vary based on supplier availability, system efficiency rating (SEER/AFUE), and whether ductwork modifications are needed.
Do I need a permit for HVAC work in Grand Rapids?
Yes. The City of Grand Rapids requires mechanical permits for all HVAC installations, replacements, and major repairs through the Building Inspection Department. Permit applications must include equipment specifications, serial numbers, and designer plans for new construction. Replacement units under 50,000 BTU may qualify for expedited permitting. Permits cost $75-$250 depending on project scope. All work requires final inspection and system verification before activation. Ductwork modifications also require permits. Processing time is typically 3-5 business days. Working without permits exposes you to fines and makes the system uninsurable.
What is the busiest season for HVAC contractors in Grand Rapids?
Winter (November through March) is peak season—heating emergencies, furnace failures, and preventive maintenance before cold snap season create constant demand. July and August form a secondary peak as air conditioning systems fail under sustained heat load. Spring and fall are moderate; homeowners do planned replacements before season changes. Emergency service calls spike during temperature extremes. Staffing should reflect this cycle; contractors who run lean year-round miss revenue November-March and face burnout. BLS data shows HVAC employment indexes peak during winter months across northern climates.
What insurance do I need as an HVAC contractor in Michigan?
Michigan law requires minimum General Liability insurance of $500,000 per occurrence and $1,000,000 aggregate for mechanical contractors. Workers' Compensation is mandatory for all employees at statutory rates based on payroll classification. Recommended additional coverage includes HVAC equipment/tools inland marine coverage, service vehicle liability, and equipment breakdown insurance. Most commercial clients and municipal contracts require proof of $1M/$2M limits. Insurance costs vary by claims history and payroll but typically run $1,500-$3,500 annually for a small operation. Have current proof of insurance before your first service call.
