Iowa HVAC & Appliance Repair Insurance Requirements (2026)

HVAC Contractors

Mechanical/HVAC Contractor License

Iowa Department of Inspections, Appeals, and Licensing (DIAL), Plumbing and Mechanical Systems Board (PMSB)
General LiabilityRequired

Minimums: $500,000 public liability insurance

Iowa Contractor License applicants — a category that by statute/rule covers plumbing, mechanical, HVAC, refrigeration, sheet metal, and hydronic systems contractors — must provide evidence of a public liability insurance policy of at least $500,000, and the policy must specify 10 days' written notice to the board before cancellation.[1]

Surety BondRequired

Minimums: $5,000 surety bond

Iowa Contractor License applicants must provide evidence of a surety bond of at least $5,000 issued by an entity licensed to do business in Iowa.[1]

Workers' CompensationConditional

Condition: 1+ employees

Contractor License applicants with one or more employees must provide proof of workers' compensation insurance; self-employed contractors with no employees are not required to submit this documentation for the license itself.[1]

Appliance Repair

General appliance repair (washers, dryers, ovens, dishwashers) is not separately licensed in Iowa. However, Iowa's Contractor License definition of 'contractor' explicitly includes anyone providing HVAC, refrigeration, sheet metal, or hydronic systems services on a contractual basis, so appliance repair technicians whose work touches built-in refrigeration or HVAC/ventilation systems may fall under the state HVAC/mechanical licensing requirements described above. For non-HVAC appliance repair, manufacturers' warranty networks, home warranty companies, and commercial landlords typically still require proof of general liability insurance (COI).

Workers' Compensation Threshold

Iowa Code §87.1 requires 'every employer' subject to the workers' compensation chapters to insure its liability — there is no numeric employee-count minimum. Exemptions are role-based rather than headcount-based: sole proprietors, partners, LLC members, and certain corporate officers owning 25%+ of stock are not automatically covered (though they may elect coverage), and narrow categories like casual/domestic labor and low-payroll agricultural workers are excluded.
