What Are the Reciprocity Requirements for an HVAC License in Idaho
Learning a trade requires hard work and determination. You can’t rush the process, but the time you put into learning how to be an HVACR technician or contractor can lead to a career that is long-lasting, lucrative, and fulfilling. There are 425,200 heating, air conditioning, and refrigeration mechanics and installers nationwide, according to the U.S. Bureau of Labor Statistics, and Idaho employs 3,570 of them.
Employment is projected to grow 8% from 2024 to 2034 throughout the country, adding more than 40,000 of these skilled workers to the ranks. In Idaho, that growth rate is projected at 27%, according to CareerOneStop, the U.S. Department of Labor’s job search website.

Contractors struggle to find skilled tradesmen like plumbers, electricians, and HVACR or mechanical professionals while the demand for them continues to grow. According to the Associated General Contractors of America, “Construction employment in Idaho in July 2025 totaled 78,000, an increase of 6,100 (8.5%) from July 2024 and an increase of 22,900 (42%) from February 2020.” So, if you get the training you need, you should have a variety of jobs to choose from when you’re ready.
A large part of what HVAC contractors and technicians do is replace and repair existing systems. As more emphasis is placed on energy efficiency and reducing pollution, systems need to be retrofitted, upgraded or replaced entirely to remain compliant with these new standards. Licensing requirements for HVAC contractors vary from state to state and, in some cases, from locality to locality. Idaho licensure is uniform statewide, beginning at the apprentice level.
Licensing Requirements for HVAC Contractors in Idaho
In Idaho, you must be licensed to legally perform heating, air conditioning and refrigeration work of any kind. The state registers or licenses every level of this workforce, including HVAC apprentices, journeymen, and contractors. The Idaho Division of Occupational and Professional Licenses (DOPL) in Boise issues licenses for HVAC, electrical, and plumbing contractors.
Licensing requirements include meeting work experience requirements, passing an exam, and paying all fees. Contractors must also obtain a compliance bond of at least $2,000.
Types of HVAC Licenses in Idaho
What are the different types of HVAC/Mechanical licenses in Idaho?
There are three main types of HVAC licenses in Idaho:
HVAC Apprentice — Works under the direct supervision of a licensed HVAC journeyman or contractor to gain practical experience and complete required training hours.
HVAC Journeyman — Performs installation, maintenance, and repair of HVAC systems. They can work independently but under the general supervision of an HVAC contractor.
HVAC Contractor — Allows the contractor to own and operate an HVAC business, train apprentices, and supervise journeymen.
Idaho also has four Specialty HVAC license categories at the journeyman and contractor level. They include:
Hearth: Install hearth appliances and the associated gas lines.
Waste Oil: Install non-duct-connected waste oil heaters. Waste oil heating specialty journeymen are limited to the maintenance, installation, and repair of the equipment, controls, and piping directly associated with the waste oil heater, tank, and burner only. Any plumbing, electrical, ducting, venting, or associated equipment beyond the waste oil heater, tank, and burner must be installed by others.
Fuel Gas Piping: Install fuel gas piping only, not the final termination. Appliances and the associated gas piping, chimney, and vents must be installed by others.
LP Gas Limited Heating: Installs, maintains, services and repairs LP gas-fired appliances, LP fuel gas piping and related exhaust venting. This definition of specialty-limited heating excludes boilers, hydronic systems, ducted forced-air systems, ventilating and air-conditioning systems, systems with a BTU input rating over 300,000, solid fuel and electric fueled systems.
Each license has specific requirements.

What Is the Mean Wage for an HVAC Technician in Idaho?
The annual mean wage for HVAC mechanics and installers in Idaho is $58,150, according to the U.S. Bureau of Labor Statistics. However, that salary increases, as you might expect, as you acquire more experience. An HVAC technician salary database, shared with ServiceTitan by Payscale.com, projects the median HVAC technician salary will increase nationally in 2025 by 3.44% for entry-level workers, 3.46% for intermediate level, 3.62% for senior level HVAC professionals, and 3.53% for supervisors. In Idaho, those salary projections are:
Entry (<2 years): $51,300
Intermediate (2-4 years): $62,300
Senior (4-7 years): $73,200
Supervisor (>7 years): $86,100
The meaning of a “mean” and “median salary” can be confusing. Here is the difference:
Mean tells you the mathematical average.
Median salary tells you the point at which 50% of workers make less and 50% make more, and is usually a better indicator of what most people actually earn.
Salaries can vary widely depending on the city where you work and other factors like education, certifications, additional skills, and the number of years you have spent in your profession. If you choose to start an HVAC business, this blog can give you an idea of what you can expect to make and what factors will influence that number.

How Long Does it Take to Get an HVAC Contractors License in Idaho?
It will take a minimum of four years to qualify for a journeyman license and an additional two years to qualify for a contractor license. Specialty journeyman licenses typically require less experience, as these license holders perform limited functions. Specialty contractors must obtain two years of experience after obtaining a journeyman license, totaling six years.
The great news is that as an apprentice, you begin earning a wage from the very beginning and that compensation goes up each year as you acquire more training and knowledge until you are fully licensed at the journeyperson level. As a licensed contractor you can start your own HVAC business, be your own boss, and grow your business as much as you want.
Idaho HVAC Training Programs and Schools
Since the state of Idaho requires HVAC professionals to begin their career journey in a registered apprenticeship, you don’t need formal education. However, you can substitute one year of formal education for practical work experience. Additionally, you may decide to take educational training to build your knowledge base and make yourself more marketable.
There are currently two main organizations that approve HVAC programs and schools nationwide: HVAC Excellence and the Partnership for Air-Conditioning, Heating, Refrigeration Accreditation (PAHRA). The College of Southern Idaho offers an HVAC Excellence-accredited program at its campus in Twin Falls. Lewis-Clark State College in Lewiston also offers an accredited program.

What Are the Reciprocity Requirements for an HVAC License in Idaho?
There are no reciprocal agreements with other states for Idaho HVAC workers.
HVAC Specific Requirements: EPA Certification
Throughout the country, including in Idaho, federal-level EPA regulations under Section 608 of the Clean Air Act require that technicians who maintain, service, repair, or dispose of equipment that could release refrigerants into the atmosphere must be certified. EPA Section 608 HVAC Certification is required for any professional who conducts refrigerant line-pressure tests or handles or adds refrigerant to existing air conditioning systems.
Most training programs can direct you to how and where to get that certification, or your employer will require you to get it before handling refrigerant. You can also go to EPA.gov and key in 608 Certification in the search bar to find out which institutions in your state offer certification programs. All apprenticeships will include this preparation and testing.
Take Certification Exam: You must acquire your EPA Certification from an approved organization. A list of these organizations can be found on the EPA’s website. There are four types of EPA Certifications for Refrigerants. They allow for different levels of certification for different scopes of work.
Type I – for servicing small appliances containing five pounds of refrigerant or less.
Type II – for servicing high-pressure units that contain five pounds or more of refrigerant (including most small commercial and residential systems).
Type III – for servicing or disposing of low-pressure appliances.
Universal – for servicing all systems and appliances covered under Types I, II, and III. Generally more useful than targeting any one specific certification.
Core Exam
For all certifications, you must pass the “Core Section” of the EPA certification exam. It covers the following topics:
Ozone depletion
Clean Air Act and the Montreal Protocol
Section 608 regulations
Substitute refrigerants and oils
Refrigeration
The Three R’s (Recover, Recycle, Reclaim)
Recovery techniques
Dehydration evacuation
Safety
Shipping
National HVAC Certifications
Other certifications can help you demonstrate your proficiency to potential employers and clients. North American Technical Excellence (NATE) certification, ASHRAE (American Society of Heating, Refrigeration and Air-Conditioning Engineers) certification, and other professional certifications are not required but can add to your marketability as a service provider and therefore increase your opportunity to make more money.
