What is the correct role of a recovery and recycling machine in HVAC service?

• A. It evacuates refrigerant during the evacuation process.
• B. It is used to remove refrigerant from a system properly during evacuation.
• C. It measures refrigerant charge in ounces.
• D. It filters refrigerant impurities.

Answer: (B)

The main idea is that a recovery and recycling machine exists to remove refrigerant from a system in a controlled, compliant way during service. When performing maintenance, you must recover the refrigerant before opening the circuit to the atmosphere. The machine pulls the refrigerant from the system, sending it into a recovery cylinder. If the unit also has recycling capability, it can purify the recovered refrigerant so it can be reused in the system, meeting purity standards. This prevents releasing refrigerant to the air and supports proper evacuation and recharge procedures. This tool isn’t primarily for measuring how much refrigerant is in the system—that’s done with a scale or charging equipment—and it isn’t solely a filter for impurities. The key role is safely removing refrigerant from the system during evacuation so it can be stored or purified for reuse.
