R32, commonly referred to as difluoromethane, is a single-component HFC refrigerant widely used in new air conditioning and cooling equipment designed specifically for R32. With zero ozone depletion potential and a lower GWP than R410A, R32 has become a common choice in modern systems where manufacturers aim to balance environmental performance and cooling efficiency. Because it is classified as A2L, mildly flammable, R32 is typically used in properly designed equipment and handled in accordance with applicable safety standards. It remains a practical option for new-generation HVAC systems that are engineered for R32 operation and service.
