Mississippi HVAC License Cost — Complete Fee Breakdown for 2026
The sticker price on a Mississippi HVAC license — $400 commercial, $50 residential — understates the real cost by a wide margin. By the time you account for exams, CPA engagements, insurance, and local bonds, the total outlay ranges from roughly $1,500 for a residential license to $5,000 or more for a commercial Certificate of Responsibility with full municipal registration.
State Application Fees
The Mississippi State Board of Contractors (MSBOC) charges two different rates depending on the license track:
Commercial Certificate of Responsibility: $400 non-refundable application fee. This covers all commercial classifications — whether you're applying for the specialty HVAC classification, refrigeration, ductwork, or the major Mechanical classification that encompasses everything.
Residential License: $50 non-refundable application fee. This covers Residential HVAC, Residential Mechanical, and other residential trade classifications.
Both fees are paid at application submission and are not refunded if the application is denied or withdrawn.
PSI Exam Fees
The MSBOC contracts with PSI Exams to administer all licensing examinations. Every applicant must pass two exam portions:
- Single exam portion: $120 (either the Law and Business Management exam or the technical trade exam)
- Both portions together: $240
Exam fees are non-refundable and non-transferable. If you fail an exam portion, each retake costs another $120. There's no limit on retakes within your six-month eligibility window, but each attempt adds to your total cost.
For budgeting purposes, assume $240 minimum (pass both on the first try) and $480 as a reasonable upper bound (one retake per exam).
CPA Financial Statement
This is the cost most applicants underestimate. The MSBOC requires a CPA-reviewed or audited financial statement — not a compilation — prepared within the preceding 12 months.
Typical CPA review engagement cost: $500–$2,000, depending on the complexity of your finances and how organized your records are when you walk in. A well-prepared applicant with clean books can keep this closer to $500. An applicant whose accountant needs to reconstruct records from bank statements and receipts will pay toward the higher end.
Residential subcontractors without a fixed net worth minimum still need a bank reference letter, which is usually free or costs a nominal processing fee.

Insurance Costs
Commercial General Liability (CGL): The MSBOC requires commercial license holders to carry minimum limits of $300,000 per occurrence and $600,000 aggregate. Annual premiums for a new HVAC contractor in Mississippi typically run $1,200–$3,000, varying by claims history, coverage limits, and business volume.
Residential CGL: The state doesn't mandate specific dollar limits for residential trade contractors, but most municipalities require proof of active liability coverage ranging from $50,000 to $500,000 to pull local permits. Budget $800–$2,000 annually.
Workers' Compensation: Required for any business employing five or more workers (including part-time and working officers). Premiums vary widely based on payroll and classification codes, but expect $2,000–$5,000 annually for a small HVAC crew.
EPA Section 608 Certification
Before you apply for a state license, you need an EPA Section 608 certification to legally handle refrigerants. Testing fees from approved providers typically run $100–$150. The certification doesn't expire, so this is a one-time cost.
Secretary of State Filing
If you're forming an LLC or corporation (which the MSBOC requires for non-sole-proprietor businesses), the Mississippi Secretary of State charges a $50 filing fee for Articles of Organization. Online processing takes 24–48 hours.
Local Municipal Costs
This layer varies by city and catches many contractors off guard:
Municipal contractor license bonds range from $2,000 to $10,000 depending on the city. Tupelo requires a $10,000 surety bond. Ridgeland requires $5,000. Jackson requires $5,000. The annual premium on a surety bond is typically 1–3% of the bond amount, so a $10,000 bond costs $100–$300 per year.
Privilege license fees vary by municipality — typically $20–$100 annually.
Permit fees for individual projects range from $50 to several hundred dollars depending on system tonnage and local fee schedules.
