Section 609 Motor Vehicle Air Conditioning Certification Test & Preparatory Manual Who Must Be Certified? Any person that services Motor Vehicle Air Conditioning (MVAC) must be certified. Servicing of motor vehicle air conditioning includes repairs, leak testing, and "topping off" of air conditioning systems low on refrigerant, as well as any other repair to the vehicle that requires dismantling any part of the air conditioner. NOTE: Service performed on HCFC-22 air conditioner systems typically found on busses, is NOT covered under section 609, but rather section 608 of the Clean Air Act. Technician certification IS required under section 608. For more information on Section 608 certification, contact The ESCO Institute at (800) 726-9696. Test Format The certification test contains 50 multiple-choice questions. All of the information necessary for the technician to achieve a passing score on the certification test is contained within this manual. The certification test will contain a variety of questions from each of the topics covered. Training and Certification Technician training and certification are not intended to test skills necessary to diagnose problems with, or to repair, motor vehicle air conditioners. Rather, training and certification teach and test technicians on how to properly recover and recycle refrigerant, appropriate handling of refrigerants, the law, and why it must be

FAQs

Who must be certified under Section 609 for MVAC work?

Any person that services Motor Vehicle Air Conditioning (MVAC) must be certified. Servicing includes repairs, leak testing, topping off low refrigerant, and other vehicle repairs requiring dismantling parts of the air conditioner.

What topics does the certification exam cover and how is it graded?

The certification test contains 50 multiple-choice questions drawn from the topics covered in the manual. Tests are electronically graded, with records maintained by the ESCO Institute’s Program Development and Grading Center.

How does refrigerant use affect the stratospheric ozone layer?

The manual explains that ozone depletion occurs when CFCs released into the atmosphere break down ozone molecules. It attributes the process to chlorine, which attacks ozone and leads to formation of chlorine monoxide and oxygen, contributing to increased harmful effects.
