What license tiers does Iowa offer?
Iowa runs a full ladder within each discipline: apprentice (licensed while training), journeyperson (36 month registered apprenticeship plus exam), master (journeyperson plus two years plus exam) and contractor (master license plus Division of Labor registration, bond and business requirements). Specialty sublicenses exist too, including the Service Technician HVAC specialty for appliance side work, which accepts NATE certification or board approved training in place of the full ladder.

Confirm the current format and vendor fee in the Kirkwood candidate information before scheduling, then train for book navigation speed.

How long does it take to become an HVAC tech in Iowa?
The clock is the 6,000 supervised hours, roughly 3 years of full-time paid work. Iowa licenses every rung of the ladder. The journeyperson exam requires completing at least 36 months in a US Department of Labor registered apprenticeship, roughly 6,000 paid hours. Two more years as a licensed journeyperson opens the master exam, and the contractor license adds business registration with the Division of Labor. Plan on three years to journeyperson and five or more to master.

What does it take to start your own HVAC business in Iowa?
The contractor license is what lets you bid and contract directly: it requires holding or employing the right master license, a contractor registration number from the Iowa Division of Labor, the required bond and insurance, a valid unemployment insurance number even if you have no employees, and evidence of a permanent place of business. Contractor and registration fees file together through the board, and CE obligations continue at every level you hold.
What most guides get wrong about Iowa
Iowa's 2010 rule is the fact that breaks people: since January 1, 2010, field experience alone no longer qualifies anyone for the journeyperson exam, only a US Department of Labor registered apprenticeship does, and plenty of older guides still describe the pre 2010 experience path as if it exists. The consolation is real: Iowa apprenticeships are paid, the multiple license discount takes 30 percent off when you stack disciplines, and crossing into Minnesota, where no state license exists at all, makes an Iowa master card one of the strongest portable credentials in the region.
Iowa HVAC license: frequently asked questions
Do you need a license to do HVAC work in Iowa?
Yes, at every level, which makes Iowa one of the most fully licensed states in the country. The Plumbing and Mechanical Systems Board licenses apprentices, journeypersons, masters and contractors across the plumbing, HVAC-refrigeration, hydronic, mechanical and sheet metal disciplines, and working unlicensed in any of them violates Iowa Code chapter 105.
How do you become an HVAC journeyperson in Iowa?
Since January 1, 2010, the only experience path is completing at least 36 months in an apprenticeship program registered with the US Department of Labor, then passing the state journeyperson exam for your discipline. The exam application is $35 per trade plus the test vendor's administration fee, and holding a master license from another state also qualifies you to test.
What is the Iowa HVAC exam like?
Exams are administered statewide by Kirkwood Community College under contract with the board, open book, passing at 75 percent. Exam providers report the journeyperson exam at roughly 75 questions over 3 hours and the master at roughly 100 questions over 4 hours; confirm current counts in the Kirkwood candidate information when you register. The allowed reference list is published, so tabbed and highlighted code books are the core prep.
What does the Iowa contractor license require?
A contractor must hold or employ the appropriate master license, register with the Iowa Division of Labor for a contractor registration number, carry the required bond and insurance, provide an unemployment insurance number even with no employees, and show a permanent place of business. Fees submitted together through the board, and DIAL offers a 30 percent discount when you carry multiple board licenses.
