How to Get Licensed
Step 1: Accumulate Work Experience
Document 5 years of full-time HVAC work for Master License or 2 years for Technician License. Experience must be verified by employers on official forms from Iowa Department of Labor. Work must include hands-on installation, service, maintenance, and repair. Self-employment counts; keep detailed records (invoices, photos, project logs). Apprenticeship hours count toward experience. No shortcuts—Department audits applications.
Step 2: Obtain EPA Section 608 Certification
Pass the EPA 608 refrigerant handling certification exam before applying for Iowa license. Exam covers Type I (small appliances), Type II (high-pressure), Type III (low-pressure), and Type IV (universal). Cost $50–$150 per attempt. Three attempts to pass. Certification valid 10 years but must be maintained for license renewal. Approved training providers exist statewide; online and in-person options available. Proof of certification required with license application.
Step 3: Submit License Application to Iowa Department of Labor
Complete official HVAC license application form with verified work experience, EPA 608 proof, and references from previous employers. Application processing: 5–10 business days. Application fee: $100–$150. Submit to Iowa Department of Labor, Construction and Licensed Professions Bureau. Incomplete applications are rejected; Department follows up but processing delays result. Provide detailed job descriptions and contact info for verifiers.
Step 4: Pass the Iowa HVAC Licensing Exam
Schedule and pass the Master HVAC or Technician HVAC exam administered by Iowa Department of Labor or approved testing provider. Exam covers code compliance, EPA regulations, safety, installation standards, troubleshooting, and state-specific rules. Master exam is more comprehensive than Technician. Cost $75–$150 per attempt. Three attempts allowed within 12 months. Study materials available from Department. Exam score required: 70% or higher. Schedule exam after application approval.
Step 5: Receive License and Register with City of Des Moines
Upon passing exam, Iowa Department of Labor issues official HVAC license valid 2 years. License number must be posted at job sites. Register with City of Des Moines Building Services if operating in Des Moines—filing fee $25–$50. License renewal every 2 years requires 24 continuing education hours and $100–$150 renewal fee. Failure to renew results in license suspension; work stoppage. Track CE credits and renew 30 days before expiration.
