Learn About EPA Technician Certification
Under authorization from Section 608 of the Clean Air Act, the U.S. Environmental Protection Agency has established a mandatory program that requires all technicians to be certified before performing maintenance, service, repair, or disposal of an appliance that contains refrigerant chemicals.
The agency has developed four types of certifications:
- Type I - for servicing small appliances
- Type II - for servicing high and very high pressure appliances
- Type III - for servicing low pressure appliances
- Universal - for servicing all appliances
To be certified, candidates must take a closed-book exam under the supervision of a chief examiner who has been registered and approved by AHRI. To learn more, click on the appropriate links below.
