How To Take the EPA 608 Exam?
To take the test first you will need to find a test location. Calling around to local HVAC supply stores or the community colleges will point you in the right direction for local test locations.
For example, when I took my EPA 608 test it was given at a local HVAC supply store. They set an appointment for me to come in when a certified person could give me the test.
Depending on the testing location and study material bought it will cost roughly between $50 and $200.
Each test location is different, they apply to be able to give the test, then are sent the exams which are mailed back to the EPA company that certified them as EPA 608 exam test locations.
