The reference guide definition of Rc states "0.5 to 5.0 lbs of refrigerant per ton of gross ARI rated cooling capacity". What do you do for equipment that has a charge of above 5.0 lbs/ton?

Hi Keith,
You should use the actual refrigerant charge in the credit calculations. However, you'll need to have very refrigerant-efficient equipment elsewhere in your project to balance out that charge and meet the credit requirements, depending on the refrigerant type and equipment lifespan.
