This condition is mainly caused by a defective or malfunctioning TXV valve. pressures were about what they should be for a cap tube system (roughly 150/25 psi) but just blowing around warm air
🕺💐HVAC Gas Very high head Pressure low suction pressure low why How While newer higher efficiency air conditioners and heat pumps run at higher suction pressures than older units, a rule of thumb used by many HVAC techs is that the low side pressure should be. pressures were about what they should be for a cap tube system (roughly 150/25 psi) but just blowing around warm air TXV failure can also be caused by a rub out on the bulb tube and an external equalizer without a core depressor installed on a port that has a Schrader core in place.
