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.

      Raffy you must take and pass the core, type I , type II and type III to get the universal. You can take the core and type I on your free time with open book BUT type II and III MUST be administered by a teacher while you take II and III and when you pass those you get the universal.. Start with the core first IMO
