    It is R22....I will have to get the building information.
    The system has 5 Amer-Flow Model Number 1500 W 14 14" Round Ceiling Diffusers. (Duct Size 14")
    It also has 2 - 6 Inch Round Celing Diffusers.....Model Number 1500 W. (Duct Size 6")

    While cleaning the evaporator coil today I observed the transition from the unit to the return duct was sheet metal 30" X 8" insulated inside with 1/2" duct liner. Thus reducing the duct dimensions to 29" X 7".....My ACCA Ductulator shows 810 CFM's for 29" X 7" metal duct @ .05 WC.....To beat it all, the 2 - 20" X 25" X 1" Return Air Filter Grilles leave their return boxes with a 14" Round Metal Duct (Each).....14" Round Pipe @ .05 WC shows 660 CFM's each X 2= 1300 CFM's. The entire return system is too small.

    so, you have your answer

    replace the duct system or downsize the condenser/coil system.
