How is refrigerant reclaimed during the servicing of an A/C system?

The correct answer highlights the importance of environmental safety and regulatory compliance when servicing an A/C system. Refrigerant reclamation involves the use of a recovery machine, specifically designed to safely capture and store refrigerant from the system during maintenance or repair procedures. This process not only prevents the harmful release of refrigerants into the atmosphere—many of which can have significant negative impacts on the ozone layer and contribute to climate change—but also complies with governmental regulations regarding refrigerant disposal.

Recovery machines are equipped to efficiently extract refrigerant from the system and contain it in a storage tank, allowing for either recycling or proper disposal without harm to the environment. This method preserves the refrigerant for possible reuse, supporting sustainable practices in the HVAC industry.

Other methods mentioned are not only ineffective but also illegal, as venting refrigerants into the atmosphere can lead to severe environmental consequences and is strictly prohibited under many laws. Similarly, using a standard vacuum cleaner or diluting refrigerants with water does not adequately remove or manage refrigerants and could lead to safety hazards.
