Illinois HVAC & Appliance Repair Insurance Requirements (2026)
HVAC Contractors
Illinois does not license HVAC/mechanical contractors at the state level. The Illinois Department of Financial and Professional Regulation (IDFPR) licenses only a handful of construction-adjacent trades statewide — roofing contractors (Roofing Contractor / Qualifying Party Roofing Contractor) are one of the few — and HVAC, air conditioning, and mechanical contracting do not appear anywhere on IDFPR's official list of regulated professions and industries. Plumbing is licensed at the state level in Illinois, but by the Illinois Department of Public Health under the Illinois Plumbing License Law, not by IDFPR, and does not cover HVAC/refrigeration work. HVAC licensing and registration in Illinois is handled entirely by individual municipalities and counties (Chicago, Springfield, and others each have their own requirements), so specific insurance/bond requirements vary by locality and are not a single statewide rule.
Appliance Repair
No state license or insurance requirement for general appliance repair in Illinois. Manufacturers' warranty networks, home warranty companies, and commercial landlords typically require proof of general liability insurance (COI). EPA Section 608 federal certification applies to any technician who handles refrigerant, independent of state licensing.
Workers' Compensation Threshold
Illinois requires workers' compensation insurance starting with an employer's very first employee, even part-time — there is no minimum headcount exemption under the Illinois Workers' Compensation Act, aside from narrow opt-outs available to sole proprietors, partners, corporate officers, and LLC members (who generally cannot opt out in 'extra-hazardous' occupations, which include construction trades).
