  1. What type of cylinder must be used when recovering refrigerant under EPA Section 608?

    Answer: A DOT-approved recovery cylinder that is properly color-coded and not filled above 80% capacity

    Recovered refrigerant must be stored in DOT-approved recovery cylinders (gray with yellow collar) and must not be filled above 80% of their capacity to allow for liquid expansion.

  2. Under EPA Section 608, what are the required evacuation levels for systems with more than 200 lbs of refrigerant using high-efficiency recovery equipment?

    Answer: 15 inches Hg vacuum

    EPA Section 608 requires systems with more than 200 lbs of refrigerant to be evacuated to 15 inches Hg vacuum when using recovery equipment manufactured after November 15, 1993.

  3. What does the AIM Act of 2020 regulate in the US HVAC industry?

    Answer: The phasedown of HFC refrigerants based on their GWP values

    The AIM (American Innovation and Manufacturing) Act of 2020 authorizes the EPA to phase down the production and consumption of HFC refrigerants by 85% over 15 years.

  4. What is the color code for a virgin (new) R-410A refrigerant cylinder?

    Answer: Pink

    New virgin R-410A refrigerant cylinders are identified by their pink/rose color, which is the standard ARI color code for this refrigerant.

  5. What is required before refrigerant can be legally sold to a purchaser in the US?

    Answer: Purchaser must be EPA Section 608 certified

    As of January 1, 2018, EPA rules require that anyone who purchases refrigerant (except small cans under 2 lbs for self-contained systems) must be certified under EPA Section 608.

  6. What is the purpose of leak detection requirements under EPA Section 608 for large commercial systems?

    Answer: To limit refrigerant losses that harm the environment and require facilities to repair leaks above threshold rates

    EPA Section 608 requires owners of systems with 50+ lbs of refrigerant to monitor for leaks and repair within 30 days if annual leak rates exceed 30% (industrial) or 20% (commercial/comfort cooling).
