The primary purpose of using a recovery and recycling machine is to ensure compliance with EPA regulations. This is vital because the Environmental Protection Agency has established guidelines to prevent the release of refrigerants into the atmosphere, which can contribute to ozone depletion and global warming. Recovery and recycling machines are specifically designed to capture refrigerants from HVAC systems during servicing or decommissioning, allowing for the safe handling, storage, and recycling of these substances according to regulatory standards.

While increasing refrigerant pressure, eliminating the need for repairs, and storing refrigerant indefinitely could be considered functions or benefits of other equipment or processes in an HVAC system, they do not encompass the main purpose of recovery and recycling machines. The focus of these machines is primarily on environmental responsibility and compliance with legal requirements, making it essential for HVAC professionals to use them during maintenance and repair activities.
