More Than One Certification

When most people begin researching an HVAC career, the first certification they hear about is the EPA 608. While EPA certification is required for technicians who handle regulated refrigerants, it is only one of many credentials that can strengthen your knowledge, improve your résumé, and open new career opportunities.

As your career grows, you may choose certifications that focus on safety, installation, troubleshooting, building maintenance, energy management, controls, or industrial reliability.
