System #1 : ( Master / Upstairs ) Outdoor TXV has failed closed / clogged. Not allowing proper amount of refrigerant into the outdoor coil. Photo attached. Tested in cooling, charge is correct System #2 : ( Main Floor ) System needs a flapper / one way damper on the dehumidifier. When dehumidifier isn’t running, it’s acting like a bypass with the unit pulling in 120* air from supply.
