Why is proper recovery of refrigerants critical?

Proper recovery of refrigerants is critical primarily because it plays a vital role in preventing harm to the environment and ensuring compliance with federal regulations. Refrigerants often contain substances that can deplete the ozone layer or contribute to global warming. Therefore, the recovery and proper disposal of these substances is not just a best practice but a legal requirement under various environmental laws. By recovering refrigerants, technicians help minimize the release of harmful chemicals into the atmosphere, which is essential for protecting both public health and the planet.

While other factors such as improving system efficiency, reducing costs, and extending equipment lifespan are important aspects of HVAC maintenance, they do not capture the overarching importance of environmental protection and regulatory compliance like the proper recovery of refrigerants does.
