Some certifications cover basic skills, while others specialize in advanced areas like new refrigerants or energy-efficient systems. The ones you choose depend on your services and your customers’ needs.
Industry Growth Alert: HVACR jobs are projected to grow 9% from 2023-2033, much faster than the average for all occupations.

- Type III: Low-pressure systems (chillers)
- Universal: Covers all equipment (most common choice)
