How much freon does a 7.5 ton unit hold?

A 7.5-ton air conditioning unit typically holds between 10 to 15 pounds of refrigerant, depending on the specific model and design. It's important to consult the manufacturer's specifications or the unit's service manual for the exact refrigerant capacity. Additionally, factors such as the length of the refrigerant lines and installation specifics can also affect the required amount. Always ensure proper handling and servicing by a qualified technician.
