Mississippi HVAC & Appliance Repair Insurance Requirements (2026)

HVAC Contractors

Mechanical Contractor (Major Classification) – Certificate of Responsibility, required for public/private contracts of $50,000 or more

Mississippi State Board of Contractors (MSBOC)
General LiabilityRequired

Minimums: $300,000 per occurrence / $600,000 aggregate

Applicants for a Mechanical Certificate of Responsibility must carry general liability insurance with minimum limits of $300,000 per occurrence and $600,000 aggregate, with MSBOC listed as certificate holder.[1]

Workers' CompensationConditional

Condition: Required only if the contractor is already subject to Mississippi's general workers' comp law (5+ regularly employed workers)

MSBOC requires proof of current workers' compensation coverage only 'if such coverage is required by state law,' i.e., when the employer meets Mississippi's statewide 5-employee threshold.[1][2]

Surety BondNot Required

MSBOC's Certificate of Responsibility rules do not require a surety bond for the Mechanical classification; applicants instead must show a minimum net worth ($50,000 for major classifications) via a CPA-prepared financial statement.[1]

HVAC and Refrigeration Contractor (Specialty Classifications: Heat/Ventilation/A.C. and Refrigeration) – Certificate of Responsibility, required for public/private contracts of $50,000 or more

Mississippi State Board of Contractors (MSBOC)
General LiabilityRequired

Minimums: $300,000 per occurrence / $600,000 aggregate

The same statewide insurance rule applies to the HVAC and Refrigeration specialty classifications: minimum $300,000 per occurrence / $600,000 aggregate general liability coverage, with MSBOC as certificate holder.[1]

Workers' CompensationConditional

Condition: Required only if the contractor is already subject to Mississippi's general workers' comp law (5+ regularly employed workers)

As with the Mechanical major classification, MSBOC requires proof of workers' compensation coverage only when the applicant is already required to carry it under state law.[1][2]

Surety BondNot Required

No statewide surety bond is required by MSBOC for the HVAC or Refrigeration specialty classifications; a minimum net worth of $20,000 (specialty classifications) is required instead, shown via financial statement.[1]

Appliance Repair

Mississippi does not license appliance repair technicians or businesses at the state level, and appliance repair work that stays under the Board of Contractors' $50,000 project-value threshold falls outside the Certificate of Responsibility requirement entirely. No state license or insurance requirement applies to general appliance repair. Manufacturers' warranty networks, home warranty companies, and commercial landlords typically require proof of general liability insurance (COI) as a condition of doing business, even though the state does not mandate it.

Workers' Compensation Threshold

Mississippi requires employers that regularly employ five (5) or more workers (full-time, part-time, seasonal, or temporary) to carry workers' compensation insurance; employers with fewer than 5 employees are not required to carry it but may do so voluntarily. Independent contractors, domestic/farm labor, and employees of qualifying nonprofit organizations are excluded from the count/coverage, and a sole proprietor, partner, or 15%+ corporate owner may voluntarily elect to be exempted in writing.
