Licenses and Certifications for HVAC Technicians

Due to the toxic and volatile nature of the materials and systems HVAC technicians work with, some certifications are either required or strongly encouraged for professionals to enter the field. Some are specific to state or federal law. Others focus on honing skills that make professionals more competent and qualified.

The Environmental Protection Agency (EPA) requires all individuals who handle refrigerants to obtain certification. This allows professionals to legally buy refrigerants and service any building's air conditioning and refrigeration systems.
There are three specializations for this exam: small appliances, high-pressure refrigerants, and low-pressure refrigerants. Technicians applying for this certification must choose a specialization.
Provided by North American Technician Excellence, the ICE certification measures basic competency in the HVAC industry. This certification serves HVAC professionals who have one year or less of experience. It measures baseline competency in residential and light commercial A/C and heating and commercial refrigeration. It is available to take online or in person. HVAC Excellence offers a variety of certifications to suit different skill levels. The professional-level certifications are for those with at least two years of verified field experience and passing grades on the core exam. Technicians who can pass both the prerequisite and closed-book exams may receive these certifications. These exams test competency in a variety of areas, including heat pump service, gas heat, combustion analysis, and light commercial refrigeration.

Essential Skills and Experience for HVAC Technicians

1. Monitoring Operations

HVAC professionals must understand how to read gauges, dials, and other indicators to determine whether something is wrong with a heating or cooling system. Knowing how to monitor these indicators is integral to performing the duties of an HVAC technician.

2. Familiarity with Design

Few associate the design of technical blueprints with HVAC technicians, but knowledge of this subject is vital to the HVAC trade. Understanding design tells technicians more about the machines they are working on.

3. Quality Control Analytics

Quality control is essential to building client relationships and a reputation as a reliable HVAC technician. Technicians who demonstrate their knowledge and competency in a clear, measurable manner impress current and future clients.

4. Reasoning

Not every solution to an air conditioning or heating problem has a textbook answer. It is important for HVAC technicians to have both inductive and deductive reasoning skills.

5. Communication Skills

Customer relationships are built on good communication. Positive business relationships calls for effective communication of issues and solutions.

6. Physical Ability

Working as an HVAC technician requires being in tight quarters. These may be outside or in uncomfortable indoor settings, especially if the heating or cooling system is broken. Having the physical capability to complete these tasks is important to becoming a successful technician.

Advice from the Field: Expert Interview

Dan Fleischer, owner of Dan's Heating and Cooling Inc.
Las Vegas, NV

Q. Where did you receive your education?

I received my education at the EC Goodwin Technical School in New Britain, Connecticut.

Q. What expectations of the field did you have as a student? How did that change after entering the field?

My life changed when I was able to do work as journeyman status in the field, and I was able to do hands-on work and earn a respectable living. They took me from the ground floor up to working status, [and] I've never been unemployed since the day I left school in 1977. My family has benefited immensely with private school, music lessons, and no students loans for college. Coming from a small town, you can't ask for much better than that.

Q. What was the best piece of advice anyone has ever given you regarding the HVAC profession?

The best advice that I received from our previous generations (or mentors) that was involved in the air conditioning field is that the minute you put your name on the side of your truck, you are now taking responsibility for their comfort and health.
