EPA 609 · Work through your exam, one topic at a time.
Section 609 of the Clean Air Act sets the training and certification requirement for people who service motor vehicle air conditioning (MVAC) systems. Under the EPA-approved program structure described by the EPA, any person who repairs or services a motor vehicle air conditioning system for consideration - payment or bartering - must be properly trained and certified under section 609 by an EPA-approved program, and all technicians servicing MVAC-like appliances must be certified. The EPA 609 study guide has 4 sections and about 2,092 words.
01Proper Use of MVAC Servicing Equipment
Domain 1 - Proper use of MVAC servicing equipment. Questions here ask a practical question: given a vehicle, a refrigerant, and a machine, do you know which equipment is legal and safe to connect, and how to run it?
512 words, about 3 min02Applicable Regulatory Requirements
Domain 2 - Applicable regulatory requirements. This domain tests the legal frame around MVAC work: who may do it, what must be recorded, what is prohibited, and what happens when the rules are broken.
544 words, about 3 min03Importance of Refrigerant Recovery
Domain 3 - Importance of refrigerant recovery. This domain tests whether you understand recovery as a process, not a formality: why it is required, how recovery differs from recycling and reclamation, how recovered refrigerant and cylinders must be handled, and what goes wrong when recovery is skipped or sloppy.
542 words, about 3 min04Effects of Improper Handling of Refrigerants on the Ozone Layer and Climate
Domain 4 - Effects of improper handling of refrigerants on the ozone layer and climate. This domain tests the science behind the rules: which refrigerants attack stratospheric ozone, which drive climate change, how those two harms are measured, and what an emitted pound of refrigerant actually means in comparable terms.
