What is an essential practice before opening or disconnecting any MVAC component?

• A. Disconnect the battery
• B. Recover refrigerant from the component
• C. Inspect all wiring and connections
• D. Turn off the vehicle engine only

Answer: (B)

Recovering refrigerant from the component is essential because it ensures safety and environmental protection. When working on any refrigerant system, including Motor Vehicle Air Conditioning (MVAC) systems, it is crucial to prevent the release of refrigerants into the atmosphere. These substances can be harmful to the environment and contribute to ozone depletion and climate change. By recovering the refrigerant before opening or disconnecting components, technicians comply with federal regulations set by the Environmental Protection Agency (EPA) and adhere to best practices for handling these materials. Additionally, recovering refrigerant protects both the technician and the vehicle's components from potential harm caused by high pressure or the presence of refrigerants during the repair process. This practice minimizes risks and promotes a safe working environment while also ensuring responsible management of refrigerant substances.
