Wisconsin HVAC & Appliance Repair Insurance Requirements (2026)

HVAC Contractors

HVAC Contractor Registration (business) with HVAC Contractor Qualifier credential (individual supervisor)

Wisconsin Department of Safety and Professional Services (DSPS)
General LiabilityNot Required

DSPS's HVAC contractor registration rule (Wis. Admin. Code SPS 305.70) does not impose a state-level general liability insurance minimum; individual municipalities and commercial project owners often require it contractually.[1]

Workers' CompensationConditional

Condition: 3+ employees at any time, OR fewer than 3 employees if the business paid $500+ in gross wages in any calendar quarter

Wisconsin employers must carry workers' compensation once they employ 3 or more workers, or sooner if a smaller employer pays at least $500 in wages in a calendar quarter.[1]

Appliance Repair

Wisconsin does not license general appliance repair. DSPS's full professions list has no 'appliance repair' or 'appliance technician' credential; the only appliance-adjacent credentials are the plumbing-specific 'Journeyman/Master Plumber — Restricted Appliance' licenses, which cover only the water-supply and drain connections for appliances like dishwashers, water heaters, and ice makers — not general mechanical or electrical appliance repair. Manufacturers' warranty networks, home warranty companies, and commercial landlords typically require proof of general liability insurance (COI).

Workers' Compensation Threshold

An employer becomes subject to Wisconsin's mandatory workers' compensation law on the day it employs 3 or more full-time or part-time employees; an employer with fewer than 3 employees is still required to obtain coverage if it has paid $500 or more in combined gross wages in any calendar quarter (coverage required within 10 days after that quarter ends).
