A 4-ton air conditioning unit typically requires about 4 to 5 pounds of R-22 refrigerant per ton of capacity. Therefore, for a 4-ton unit, you would need approximately 16 to 20 pounds of R-22. However, the exact amount can vary based on the specific system design and any existing refrigerant in the system, so it's best to consult the unit's manual or a professional technician for precise requirements.
