Don’t Just Add Refrigerant to a System Before You Know the Issue

The homeowners of a medium-sized house complain of reduced airflow coming from their registers during the summer. Their air conditioner is a 4-ton (48,000 Btuh), R-22 split system with the A-coil in the plenum of the furnace located in the basement. The evaporator has an orifice for a metering device, and the condensing unit is located on the east end of the house.
