Why is it important to recover refrigerants before servicing a system?

Recovering refrigerants before servicing a system is crucial primarily to avoid releasing harmful substances into the environment and to comply with regulations. Refrigerants can be potent greenhouse gases, and their uncontrolled release can contribute significantly to ozone depletion and climate change. The Environmental Protection Agency (EPA) has established strict guidelines and regulations to ensure that technicians handle refrigerants responsibly. By recovering the refrigerants, technicians not only help protect the environment but also adhere to legal requirements, which can include hefty fines for non-compliance.

While the other reasons listed may have some relevance in specific scenarios—such as potential efficiency gains or cost savings—the priority should always be the environmental impact and regulatory compliance. Thus, the practice of refrigerant recovery is primarily rooted in environmental responsibility and the need to follow established laws.
