SITUATION:

Ongoing testing and reports from the field indicate that Thermostatic Expansion Valves (TXV) in 1.5, 2 and 2.5 ton indoor coils installed with the above listed condensing units may not maintain the correct SuperHeat (SH) in certain situations. The end result is a lack of cooling for the homeowner due to high SH and low suction pressures measured at the outdoor unit.
