EPA 608 Certification Practice Test 2

Question 1

Under EPA Section 608, which of the following activities requires the technician to be certified?

Accepted Answer

Opening a refrigerant circuit to replace a component

Answer

EPA Section 608 certification is required for any technician who opens a refrigerant circuit — meaning any work that involves recovering, adding, or potentially releasing refrigerant. Installing ductwork, testing electrical components, and programming thermostats do not involve working with the refrigerant circuit and do not require EPA 608 certification.

Question 2

What does the term "technician" mean specifically under EPA Section 608 regulations?

Accepted Answer

Anyone who maintains, services, repairs, or disposes of appliances containing regulated refrigerants

Answer

Under EPA Section 608, a "technician" is defined as anyone who performs maintenance, service, repair, or disposal of appliances that could reasonably be expected to release refrigerants into the environment. This includes HVAC contractors, refrigeration mechanics, and service technicians — not building owners adjusting their own equipment.

Question 3

Which EPA 608 certification type covers hermetically sealed systems containing 5 pounds or less of CFC or HCFC refrigerant?

Accepted Answer

Type I

Answer

Type I certification under EPA Section 608 covers small appliances — hermetically sealed systems manufactured, charged, and tested at the factory, containing 5 pounds or less of CFC or HCFC refrigerant. Examples include household refrigerators, window air conditioners, and dehumidifiers. Type I technicians use different recovery techniques appropriate for these sealed systems.

Question 4

What type of approved testing organization administers the EPA Section 608 technician certification exam?

Accepted Answer

EPA-approved certifying organizations (e.g., ESCO, NATE, RSES)

Answer

EPA Section 608 technician certification exams must be administered by EPA-approved certifying organizations. The EPA approves third-party organizations — such as ESCO (now HVAC Excellence), NATE, RSES, and others — to develop and administer the standardized certification tests. The EPA itself does not directly administer these exams.

Question 5

What must an employer do if a new employee was previously certified under EPA Section 608 but lost their certification card?

Accepted Answer

Contact the original certifying organization for a replacement card

Answer

EPA Section 608 certification does not expire once earned. If a technician loses their certification card, they should contact the certifying organization that issued the original certificate to request a replacement. The technician does not need to retake the exam as long as they were originally certified through an EPA-approved program.
