Comfort cooling appliances that contain more than 50 pounds of refrigerant are subject to EPA leak repair rules. The requirement kicks in when the annual leak rate—the amount of refrigerant that escapes in a year divided by the total refrigerant charge, expressed as a percentage—exceeds 15 percent. So, if a unit holds 60 pounds and leaks 9 pounds in a year, that’s a 15% leak rate, and it must be repaired. This 15% threshold is the trigger for mandatory repair, meaning rates below it don’t require repair under this regulation. The rule targets larger systems to reduce emissions and applies specifically to comfort cooling appliances with more than 50 pounds of refrigerant; smaller devices have different requirements.
