  1. Under EPA Section 608, what is required before releasing A2L refrigerants into the atmosphere during service?

    Answer: Refrigerant must be recovered using certified recovery equipment

    EPA Section 608 prohibits venting of all refrigerants used in stationary refrigeration and AC equipment, requiring recovery before any service or disposal work regardless of refrigerant type.

  2. Which US federal law authorizes the EPA to phase down high-GWP HFC refrigerants, driving the transition to A2L alternatives?

    Answer: AIM Act (American Innovation and Manufacturing Act)

    The AIM Act authorizes EPA to phase down HFCs by allocating and reducing production and consumption allowances, directly driving the industry transition to lower-GWP A2L refrigerants like R-454B.

  3. What certification is required to purchase regulated refrigerants for stationary HVAC/R equipment under EPA Section 608?

    Answer: EPA Section 608 Type I, II, III, or Universal certification

    EPA Section 608 requires technicians to hold appropriate certification (Type I, II, III, or Universal) to purchase regulated refrigerants for stationary equipment, which is separate from A2L-specific safety training.

  4. Which environmental metric is primarily used to compare the climate impact of A2L refrigerants versus legacy HFCs like R-410A?

    Answer: Global Warming Potential (GWP)

    GWP measures a refrigerant's heat-trapping ability relative to CO₂ over a 100-year period; A2L refrigerants like R-454B (GWP ~466) offer significantly lower GWP than R-410A (GWP ~2,088).

  5. Under the EPA SNAP program, what is its primary function related to A2L refrigerants?

    Answer: It evaluates and lists acceptable substitutes for ozone-depleting substances

    SNAP evaluates substitute refrigerants for ozone-depleting substance applications and lists acceptable alternatives, including A2L refrigerants, based on their overall risk to human health and the environment.

  6. What is the ozone depletion potential (ODP) of current A2L HFC refrigerants such as R-32 and R-454B?

    Answer: 0

    Modern A2L HFC refrigerants like R-32 and R-454B have an ODP of zero because they contain no chlorine or bromine atoms that would deplete the stratospheric ozone layer.
