2016 AHRI Guideline N Specifies Silk Gray on all Refrigerant Containers by 2020
In 2016 some significant changes to refrigerant paint color designations were recommended by the Air-Conditioning, Heating, and Refrigerant Institute (AHRI). In their Guideline N, Assignment of Refrigerant Container Colors, AHRI reversed conventional long-term practice in the industry. Previous AHRI Guidelines had specified industry-standardized Pantone paint colors of all refrigerant gases to help handlers immediately identify gases on sight.

R-22 was the most common refrigerant used in HVAC systems for decades. However, R-22 is a Chlorofluorocarbon (CFC) which has been phased out under the Montreal Protocol since it is an ozone-depleting substance. In fact, starting in 2020, it is illegal to produce R-22 in the United States. Consumers can still operate existing R-22 systems using gas which was produced before 2020 (allowing them to replace aging A/C equipment in an appropriate manner), but R-22 supplies will not last forever. A variety of replacements provide alternatives that can be used without replacing R-22 systems.
