Refrigerant R438A (MO 99) is a hydrofluorocarbon (HFC) refrigerant designed as a non-ozone depleting alternative to traditional HCFCs. It is ideal for retrofitting existing refrigeration and air conditioning systems that use direct expansion evaporators and positive displacement compressors.
When you order from A-HVAC, you can be confident that you’re receiving 100% virgin, brand new refrigerant that meets or exceeds ARI-700 standards.
