HVAC TECHNICIAN
Installs, maintains, repairs heating, ventilation, air conditioning, and refrigeration. Year-round demand, climate-change tailwind. Iowa is a right-to-work state — union density is lower than the national average, but licensed tradespeople still command solid wages on prevailing wage projects.
The License.
Most states issue a journeyman license (allows you to work under a licensed contractor) and a separate master or contractor license (allows you to pull permits and run your own business). The journeyman license typically requires completing your apprenticeship and passing a written exam; the master/contractor license requires additional field hours — usually 2 years as a journeyman — and a separate exam.
Requirements in Iowa: confirm current hour and exam requirements directly with Iowa Plumbing and Mechanical Systems Board (DIAL). Rules update frequently and our data reflects published standards as of early 2025.

The Exam.
Licensing exams for hvac technician work typically cover the applicable mechanical code (IMC or state-specific), plumbing code (IPC or UPC depending on the state), and material standards. Iowa may adopt different code editions than adjacent states. Confirm the specific code edition before purchasing prep materials. Note: prevailing wage rules in Iowa apply primarily to public projects — private-sector jobs in this right-to-work state are exempt.
Be honest about pass rates. Many licensing boards do not publish them. When they do, first-time pass rates for journeyman exams in the trades typically run 50–75%. Preparation time varies — most serious candidates spend 60–120 hours on exam prep. Use code books from the correct edition, not what's currently in print.
