Kansas City HVAC Contractor License

Kansas City licenses HVAC contractors through the City Planning & Development Department — Permits Division. Missouri has no statewide HVAC contractor license; contractors must apply locally before performing any heating, ventilation, or air conditioning work inside city limits.

Exam Required: Prometric 31325 or ICC W29, 70% Passing Score

Applicants must pass the city HVAC contractor examination — either the Prometric Heating, Air Conditioning, Refrigeration and Ventilation exam (code 31325) or the ICC Standard Master Mechanical exam (W29) — with a minimum passing score of 70%.

Federal EPA Section 608 certification is required separately for any technician who services, repairs, or disposes of refrigerant-containing equipment. This is a federal credential issued through EPA-approved certifiers and must be in place before handling refrigerants, independent of city licensing.

Insurance: $1,000,000 general liability per occurrence with the City of Kansas City listed as additional insured; workers' compensation coverage required.

$60 Application, $181 License Fee — Confirm Renewal Interval with KCMO

The application fee is $60. The trade license fee is $181. Confirm the renewal interval directly with the Permits Division at cdlicensing@kcmo.org — current sources do not agree on whether the qualification certificate renews on a 2-year or 4-year cycle. No continuing education is required to renew.

Permits Required Per Project, License Number on Each Application

A Kansas City HVAC license authorizes installation, maintenance, and repair of HVAC systems within city limits. Permits are required per project; the license number must appear on each permit application. Unlicensed HVAC work can result in stop-work orders, permit denial, and fines.

Kansas City, Kansas Requires Separate Credentials

The Kansas City metro spans both states. Contractors working in Kansas City, Kansas (Wyandotte County) must hold a separate Kansas credential — that system operates independently of this Missouri city license.
