Mississippi HVAC License Requirements (2026)

Mississippi State Board of Contractors (MSBOC) licenses HVAC contractors. A commercial contractor or subcontractor needs the appropriate MSBOC license for commercial work over $50,000. A residential subcontractor performing HVAC work on residential construction or improvement must also be licensed by MSBOC; the Board’s current guidance says that residential-subcontractor requirement is not limited by project value. Local permit and inspection rules remain separate. Technicians who handle refrigerants also need the applicable federal EPA Section 608 certification.

Regulatory Body

Licensing for this trade is governed by Mississippi State Board of Contractors (MSBOC), the agency that issues and regulates the credential under Mississippi Code Title 31, Chapter 3; Title 73, Chapter 59. Licenses commercial and residential contractors, including HVAC classifications; reviews applications, qualifying parties, financial documents, insurance, examinations, and renewals.

Eligibility Requirements

This guide does not establish a minimum applicant age; confirm any age requirement with the issuing authority. Applicants must provide a Social Security Number. MSBOC licenses resident and nonresident applicants. Business entities must provide Mississippi Secretary of State good standing; individual/sole-proprietor applicants are excepted from that proof.

Good moral character

A qualifying party must make complete application disclosures. MSBOC states that a conviction does not itself preclude licensure, but failing to disclose required information can result in denial.

Background investigation

Use the current MSBOC application for required disclosures; do not assume a universal fingerprint or background-check process from the published guidance.

Experience and Education

Rather than a set number of years, the cited materials define eligibility through The qualifying party must document hands-on experience in the classification sought. MSBOC’s current application guidance requires detailed completed-project information and proof of employment; it does not publish the former generic four-year municipal pathway as a statewide rule..

Accepted proof of experience or eligibility

Current MSBOC commercial or residential application
Proof of employment for each qualifying party
Detailed completed-project experience for the requested classification
Reference letters and other documents required by the current application
Applicable EPA Section 608 technician certification for refrigerant work

Education substitution

Confirm any education credit directly with MSBOC; no statewide substitution formula is stated in the current guidance reviewed.

Exam Requirements

Testing provider or authority: Mississippi State Board of Contractors / its current testing process. The following examination requirements cover the pathways described in this guide; follow each part's classification, waiver, and local-scope conditions. Unpublished format details do not remove an examination requirement:

Mississippi Law and Business Management examination — question count: confirm with the authority, timing: confirm with the authority, passing score: confirm in the current candidate bulletin
Required HVAC classification examination — question count: confirm with the authority, timing: confirm with the authority, passing score: confirm in the current candidate bulletin
EPA Section 608 technician certification, when refrigerant work is performed — question count: confirm with the authority, timing: confirm with the authority, passing score: confirm in the current candidate bulletin

Examination fee: MSBOC sends testing information after it receives a completed application. Confirm the current examination fee and bulletin before scheduling. EPA testing costs are set by approved providers.

Retake policy: Follow the current MSBOC and EPA testing instructions. Do not rely on the removed unsupported PSI question-count, time, score, or fee claims.

Insurance and Bonds

There is no statewide surety bond tied to this credential in the cited record. Bonding can still surface at the project level — permit, license, or public-works bonds — so check before you bid.

General liability

Commercial applicants and active commercial renewal applicants must provide a general-liability certificate. MSBOC states a commercial minimum of $300,000 per occurrence and $600,000 aggregate. Residential applicants must provide proof of coverage; the published guidance does not state a residential minimum.

Workers' compensation

Provide workers’ compensation coverage if required by law. MSBOC’s application guidance specifically calls for the certificate when the applicant has five or more employees.

Additional financial requirements

Commercial applicants need a CPA-reviewed financial statement showing at least $50,000 net worth for a major classification or $20,000 for a specialty classification. Consult MSBOC to determine the appropriate commercial HVAC scope and classification.

HVAC Licensing in Neighboring States

Contractors working near a state line, or weighing where to qualify first, should compare Mississippi's requirements against the bordering jurisdictions before committing to an application:

Alabama HVAC License Requirements — Alabama Certified Heating and Air Conditioning Contractor

Step-by-Step Application Roadmap

Identify the project type and scope. Commercial work over $50,000 requires the commercial license; residential HVAC subcontractors require MSBOC licensure regardless of project amount.
Choose the correct MSBOC classification. Use Residential HVAC for residential HVAC work. For commercial scope, use MSBOC’s classifications guidance and confirm the appropriate Mechanical Work or HVAC classification with the Board.
Designate a qualifying party. The qualifying party must be an owner, officer, responsible managing employee, or executive staff member and document qualifying experience.
Prepare application documents. Include the current application, experience/proof-of-employment materials, references, insurance, and business documents that apply.
Meet financial requirements if commercial. Submit the required CPA-reviewed statement; commercial specialty applicants must show the current net-worth minimum.
Pass required examinations. MSBOC says all applicants take Law and Business Management and may also need the classification trade examination.
Meet refrigerant and local requirements. Obtain the applicable EPA Section 608 credential before handling refrigerants and check the local building authority for permits and inspections.

Common Filing Mistakes

The following pitfalls summarize the issues most likely to delay, return, or derail a Mississippi HVAC application based on the published board instructions and source materials cited on this page.

Calling Mississippi HVAC “municipal only”

MSBOC licenses both commercial HVAC at the commercial threshold and residential HVAC subcontractors statewide.

Using the commercial threshold for residential subcontracting

Residential HVAC subcontractor licensure is not limited by project amount.

Treating MSBOC licensure as refrigerant certification

EPA Section 608 is a separate federal requirement for covered refrigerant work.

Skipping local permits

MSBOC licensure does not remove local building-permit or code requirements.
