  1. Starting January 2025, new residential AC equipment in the US must use refrigerants with GWP below what threshold?

    Answer: GWP 700

    The EPA Technology Transitions Rule sets a maximum GWP of 700 for new residential and light commercial AC systems manufactured after January 1, 2025.

  2. Can a technician with only EPA Section 608 certification legally install A2L refrigerant equipment?

    Answer: Section 608 covers refrigerant handling, but local codes may require additional A2L safety training for installation

    EPA Section 608 is necessary for refrigerant handling but may not be sufficient for A2L installation. Many jurisdictions and manufacturers require A2L-specific safety training.

  3. What documentation must be provided to the building owner after installing an A2L refrigerant system?

    Answer: System information including refrigerant type, charge amount, safety warnings, maintenance requirements, and leak detection system operation instructions

    Building owners need complete information about their A2L system for ongoing safety, maintenance, and emergency preparedness. Documentation should be thorough and retained with the building records.

  4. How do A2L regulations differ for commercial versus residential installations?

    Answer: Commercial installations may have different charge limits, additional leak detection requirements, and stricter ventilation standards based on occupancy type and refrigerant quantity

    Commercial A2L installations often face more complex requirements due to larger system sizes, different occupancy types, and the involvement of multiple codes (mechanical, building, fire).

  5. What is the technician's obligation if they discover a code violation during service on an existing A2L system?

    Answer: Document the violation, inform the building owner, and recommend corrective action; report to the AHJ if it poses an imminent safety hazard

    Technicians have a professional and often legal obligation to report safety hazards. At minimum, inform the owner in writing and document the finding.

  6. What training must HVAC technicians complete before working with A2L refrigerant systems?

    Answer: Manufacturer-specific training and A2L safety certification covering flammability hazards, charge calculations, leak detection, and emergency procedures

    A2L refrigerants introduce flammability hazards not present with R-410A. Comprehensive training covering the specific risks and safe work practices is essential and increasingly required.
