If you’re training to become an HVAC technician, earning professional certifications can boost your job prospects, prove your skills, and help you qualify for higher-paying positions. Below are three of the most important certifications in the HVAC industry and what you need to know about each one.
NATE Certification
The North American Technician Excellence (NATE) certification is one of the most respected credentials in the HVAC field. To earn it, technicians must pass a rigorous knowledge-based exam that covers installation, service, and repair. NATE-certified techs are highly valued by employers and often command better pay. If you’re preparing, try this NATE certification practice test.
EPA 608 Certification
The EPA Section 608 certification is legally required for any HVAC technician who works with refrigerants. There are three main levels:
- Type I – Allows you to service small appliances with less than 5 pounds of refrigerant.
- Type II – Covers high-pressure refrigerants commonly used in residential and commercial systems.
- Type III – Authorizes work with low-pressure refrigerants.
Without this certification, you cannot legally handle refrigerants. Prepare with this EPA 608 practice test. Learn more about how long HVAC training takes before certification.
Excellence Certification
The Excellence Certification has two tiers: Professional and Master Specialist. To earn the Professional credential, you’ll need at least two years of field experience plus a passing score on a specialty exam (such as residential air conditioning). The Master Specialist level requires three years of experience and a higher level of demonstrated expertise. This credential shows employers your commitment to professional growth.
