Apprentice Licensure

Ready to jump right in and get your hands dirty? Finding a licensed HVAC contractor willing to let you work under a journeyperson or master level technician will allow you to obtain an apprentice license and begin work in the HVAC industry.

An apprentice must work under a journeyperson, or master level technician He or she cannot perform HVAC-related work for unlicensed contractors. To become an apprentice you must be 18, submit all required paperwork, and provide proof of being enrolled in an apprenticeship program. Once you have all that in place, submit it to the Iowa Plumbing & Mechanical Systems Board.

Service Technician HVAC Specialty License

If you wish to become proficient at HVAC repair work before you enter the industry, the Service Technician HVAC Specialty License may be for you. This license allows you to repair or replace the components of, and immediately related to, an HVAC system.

Most people get this certification by attending a technical college or an accredited institution in Iowa. Look for a school that trains HVAC personnel and provides North American Technician Excellence, Inc. (NATE) certification.

Journeyperson License

You can acquire an HVAC journeyperson license by meeting these conditions:

  • four years apprentice experience
  • required paperwork
  • a passing grade on the journeyperson examination

If you already possess a journeyperson license in another jurisdiction, you may be exempt from the exam.

When you have these materials ready, you can submit them to the Iowa Plumbing & Mechanical Systems Board

A journeyperson performs higher level tasks than apprentices, supervises licensed apprentices (if they work under the same licensed contractor), and works under a master level technician. Journeypersons are not allowed to perform work for unlicensed contractors or supervise unlicensed persons.

Master Level Technician License

Once a journeyperson has two years of work experience, they may test for their master level technician license. First, you need to submit the proper paperwork and application to the Iowa Plumbing & Mechanical Systems Board. A master license may also be acquired if you already possess a master license in another jurisdiction.

The Iowa Plumbing & Mechanical Systems Board states, “"Master" means any person who works in the planning or superintending of the design, installation, or repair of HVAC systems and is otherwise lawfully qualified to conduct the business of HVAC systems, and who is familiar with the laws and rules governing the same.”

Master HVAC technicians may only work for one contractor in an HVAC master technician capacity. Master level technicians may not work for unlicensed contractors or supervise unlicensed persons.

HVAC Contractor License

To obtain an HVAC Contractor license in Iowa, you must provide:

  • the required paperwork
  • proof of being properly bonded and insured
  • a valid unemployment insurance number
  • a permanent place of business
  • and either possess an HVAC master level technician license or employ at least one licensed HVAC master level technician

Of course, there is always the risk of the master technician leaving the business or losing their license. The contractor must notify the board within thirty days of losing their master level technician. In that case, the contractor then has a six-month grace period to provide the board with proof of employing at least one licensed HVAC master level technician.


To become an apprentice there is no examination. You must only show proof you are enrolled in an approved apprenticeship program and provide the required documents.

The examinations for journeyperson and master level technicians are held at any one of the fifteen Kirkwood Community College testing centers located across the state. A fee of $99.00 is charged to take any of the exams. Additional information can be found at the Kirkwood Community College state disciplines exam page.
