Connecticut HVAC & Appliance Repair Insurance Requirements (2026)

HVAC Contractors

Heating, Piping and Cooling (H&P) Contractor License — Unlimited (S-1) and Limited classes (S-3, S-7, S-9, B-1, B-3, D-1, D-3, G-1, PP-1)

Connecticut Department of Consumer Protection (DCP), Occupational & Professional Licensing Division
Workers' CompensationRequired

Minimums: Compliance with all state workers' compensation and unemployment insurance requirements (no specific dollar coverage minimum set in statute)

Before a contractor-level H&P license (e.g., S-1, D-1) is issued, the applicant must furnish DCP with evidence that they will comply with all state workers' compensation and unemployment insurance requirements.[1]

Home Improvement Contractor (HIC) Registration — only applies to HVAC businesses doing home-improvement work outside the scope of their trade license; licensed H&P contractors working strictly within their trade license scope are exempt

Connecticut Department of Consumer Protection (DCP), Trade Practices Division
General LiabilityRequired

Minimums: $20,000 minimum general liability coverage

Every applicant for (or renewal of) an HIC certificate of registration must provide proof of general liability insurance of at least $20,000.[1]

Surety BondConditional

Minimums: $15,000 surety bond

Condition: Only imposed by the DCP Commissioner as a condition of issuing, renewing, or reinstating a certificate — e.g., following disciplinary action — not required of all HIC registrants by default

DCP may require an HIC registrant to post a $15,000 surety bond as a condition of issuance, renewal, or reinstatement of the registration.[1]

Appliance Repair

No state license or insurance requirement for appliance repair. Connecticut DCP's full list of license/permit/registration categories has no 'appliance repair' or 'appliance service technician' category. Manufacturers' warranty networks, home warranty companies, and commercial landlords typically require proof of general liability insurance (COI). If a repair involves electrical, gas, or HVAC/refrigerant work, that portion of the job may require a separately licensed trade (electrician, plumber/pipefitter, or H&P contractor).

Workers' Compensation Threshold

Connecticut requires virtually all employers with employees to carry workers' compensation insurance, with no minimum employee-count exemption; sole proprietors are not automatically covered unless they elect in, and corporate officers, LLC members, and partners may elect to be excluded.
