We are an approved U.S. EPA technician certification provider
Section 608 of the Federal Clean Air Act requires that technicians who maintain, service, repair, or dispose of equipment that could release ozone depleting refrigerants into the atmosphere must be certified.
Starting on January 1, 2018, this requirement will also apply to appliances containing most substitute refrigerants, including HFCs.
Technicians are required to pass an EPA-approved test to earn Section 608 Technician Certification. The tests are specific to the type of equipment the technician seeks to work on.
Tests must be administered by an EPA-approved certifying organization. Section 608 Technician Certification credentials do not expire.
Core tests taken as an open book exam cannot be used to get your Universal Certification.
The core test must be taken as a proctored exam in order to attain Universal Certification.
The EPA has approved nearly 100 certification programs and provided them all with an identical bank of test questions.
DeHart Technical School is proud to announce that it was chosen to be an approved U.S. EPA technician certification provider effective March 14, 2019.
