EPA Drops Refrigerant Threshold to 15 Pounds for High-GWP Systems

The U.S. Environmental Protection Agency lowered the refrigerant threshold from 50 pounds to 15 pounds for systems containing high-global warming potential refrigerants on January 1, 2026. Since the start of the year, this rule has brought an estimated 70% more systems under federal oversight. Small commercial HVAC units that were previously exempt now require the same leak detection, repair, and reporting as larger systems.
This change hits contractors who service walk-in coolers, small rooftop units, and compact refrigeration systems. You're now responsible for compliance documentation on thousands of additional units. That means tracking refrigerant charge levels, repairing leaks within mandated timeframes, and filing reports when thresholds are exceeded. Non-compliance can result in penalties that start at $51,570 per violation per day.
Review your service route and identify which units now fall under the 15-pound threshold. Update your recordkeeping system to track charge weights and leak rates for these newly covered systems. Train your techs on the reporting requirements before their next service call.
Key Takeaways:
- EPA threshold dropped from 50 to 15 pounds on January 1, 2026
- Rule expands compliance requirements by an estimated 70% across affected systems
- Penalties for non-compliance start at $51,570 per violation per day
- Walk-in coolers and small rooftop units now require federal documentation
