The EPA 608 certification is required by law for any technician who purchases or handles refrigerants. It covers safe handling, leak detection, recovery, and environmental regulations.

Type I covers small appliances (≤5 lbs refrigerant), Type II covers high-pressure systems, Type III covers low-pressure systems, and Universal covers all three. Most HVAC technicians pursue Universal certification.

You must score at least 70% on each section of the exam. The Universal exam has four parts: core, Type I, Type II, and Type III.

Passed the EPA 608 universal exam on my first attempt. Used these core practice tests for about two weeks beforehand. The refrigerant handling and safety questions here are very close to what's on the actual Prometric exam. Worth every minute.
