The EPA Section 608 certification is legally required before you can handle refrigerants. Take the exam at an EPA-approved testing organization. Cost: $20–$50.

Earn NATE certification

NATE (North American Technician Excellence) certification is the industry standard. Specializations include air conditioning, heat pumps, gas furnaces, and commercial refrigeration.

Get your state HVAC license (if required)

Most states require an HVAC license for independent work. Requirements vary significantly — check your state contractor licensing board. Some states require additional exams and experience hours.
