What is an EPA technician certificate? What are its different types?

 If you are planning to repair a system or container holding a controlled refrigerant, you need to be certified according to section 608 of the Federal Clean Air Act. This act says that all individuals who maintain, repair, or service appliances containing regulated refrigerants should be certified by passing EPA 608 examination. EPA 608 technician certification consists of the following four sections-
Core- It covers basic knowledge about refrigerants and their regulation. Learning the core section well can help you understand the further section materials. A core is not a certification itself, but a person should pass core and at least one more section if he wishes to get a certification card.
Type-I - This section material involves small appliances with 5lbs or less refrigerant. These appliances are sealed at the factories, for example- domestic refrigerants, window AC, PTAC or vending machines, etc. Passing the core and type-1 sections can make you a certified type-1 Technician.
Type-II - It covers equipment that uses high-pressure refrigerants. For example- Residential AC’s and heat pumps, process refrigeration or supermarket refrigeration, etc. If you pass the core and type-2 sections, you will become a certified type-II technician.
Type-III- A person who has passed both the core section and Type-III section will be a certified type-III technician. This section material covers the handling of equipment that uses a low-pressure refrigerant, i.e., HCFC-123 or CFC-11. For example- Primary chillers.
If you wish to have a universal EPA technician certification, you need to pass all the above-described sections. There is no separate universal section of the test.
