Equipment must be certified to EPA standards to recover which refrigerants?

• A. CFC
• B. HCFC
• C. HFC
• D. CFC, HCFC, and HFC

Answer: (C)

The key idea is that gear used to recover refrigerants must meet EPA standards so it can safely and effectively remove refrigerants from systems during servicing or disposal.

HFC refrigerants are the focus here because they are the modern replacements for ozone-depleting substances and are regulated for proper recovery under EPA rules. Recovery equipment certified to EPA standards ensures these refrigerants are captured rather than released, which helps control greenhouse gas emissions and keeps technicians compliant with current regulations.

CFC and HCFC are older classes tied to earlier regulations, and while handling any refrigerant requires proper equipment, the question’s framing points to HFCs as the refrigerant type that specifically requires EPA-certified recovery equipment in this context.
