What is the main purpose of recovering refrigerant from an air-conditioning system?

The main purpose of recovering refrigerant from an air-conditioning system is to prevent exposure to the atmosphere. This is critical because many refrigerants have harmful effects on the environment, particularly on the ozone layer and contribute to global warming. Proper recovery minimizes the release of these substances, aligning with environmental protection laws and regulations, such as those enforced by the Environmental Protection Agency (EPA).

This responsibility not only helps in complying with regulations but also reflects best practices in the HVAC industry, ensuring that refrigerants are handled safely and responsibly. By recovering refrigerants, technicians can safely manage these substances without allowing them to escape into the atmosphere during maintenance or repairs.
