Example of how to fix a 3 ton 16 SEER AC unit running on R-22 freon that has high superheat and low subcooling: Add R-22 refrigerant (but only after you fix the leak, more below). To simplify this, we can say that: High Superheat = Amount of refrigerant in the evaporator coil is too low. Low Subcooling = Amount of refrigerant in the condenser ... To determine the Target Superheat for an air conditioning system with a fixed orifice (such as a piston or capillary tube) measure the indoor WB (wet bulb) temperature with a digital psychrometer and the outdoor DB (dry bulb) temperature with a standard digital temperature reader. Input these temperatures in a superheat chart, …Generally, you will see normal superheat (8-14) on a system with heat mode TXV and the subcooling will generally be a bit higher than usual, especially when measured outside. Suction Pressure / EVAP DTD Rule of Thumb Another common old school rule of thumb is suction pressure should be close to the outdoor temperature in …According to the R-22 PT chart, this is equal to about 54°F. With the thermometer, we measured the saturated R-22 temperature of 45°F. Here is how we can calculate the R-22 superheat in this system: Superheat (R-22) = 54°F – 45°F = 9°F. The superheat calculator also gives us 9°F superheat for R-22 refrigerant.

Here is a chart that contains low superheat causes and low subcooling causes: Indoor airflow (CFMs) is too low. Oversized AC unit.
