Step One: Choose the EPA Type(s) for which you wish to seek
The Federal Government of the United States requires all individuals
who open a system or container holding a controlled refrigerant
to be certified. Persons who work on stationary equipment or use
refrigerant designed for these systems can become certified by passing
a proctored Section 608 examination. Candidates for this test can
be certified in any of three equipment categories plus Universal.
Read the descriptions, and choose the certification type that seems
most like you.
- Type I - A Type I technician primarily works on small appliances
such as domestic refrigerators, window air conditioners, PTAC's
and vending machines.
- Type II - A Type II technician primarily works on equipment
using a high pressure refrigerant such as HCFC-22. The equipment
includes residential air conditioners and heat pumps, supermarket
refrigeration and process refrigeration.
- Type III - A Type III technician primarily works on equipment
using a low pressure refrigerant such as HCFC-123 or CFC-11. The
units are primarily chillers.
- Universal - Any candidate passing all three of these EPA types
is certified as UNIVERSAL.
Note: To pass any EPA type, a candidate must pass a CORE section
of the test plus one of the technician types listed above. Once
CORE is passed it need not be taken again and it may be used for
additional EPA types.
Step Two: Register for a testing session.

Preparation time needed for the Section 608 test may vary greatly
from one technician to another. Typically, a technician with a working
knowledge of HVAC terms and techniques may not require as much time
as a person just entering the HVAC field. No matter what background
a person might have, the probability of passing the Section 608
test is greatly increased by studying VGI's EPA Section 608 Applicant
Study Guide in advance.
