Do you add refrigerant to raise superheat?
The difference between the measured liquid line temperature and the saturated condensing temperature is the liquid subcooling. Add refrigerant to increase subcooling. If the expansion valve goes bad, you can have a very low suction superheat when you have the proper subcooling.Click to see full answer. Also question is, how can I increase my superheat?…

MAKING AN ADJUSTMENT Carefully remove the hex cap from the base of the valve with a properly sized wrench and a backing wrench exposing the adjustment screw; Turn 1/2 turn at a time clockwise to increase superheat or counter-clockwise to decrease superheat; Similarly, how do you increase superheat fixed orifice? Adding refrigerant (on a fixed orifice / piston / cap tube) will feed the coil with more refrigerant resulting in a lower superheat. Removing refrigerant will increase the superheat by feeding less of the coil with saturated (mixed liquid and vapor) refrigerant. Also, what causes low superheat? The result is lower superheat, high suction pressure, high discharge pressure and lower sub-cooling. The most common cause of low condenser air flow is a dirty coil. This condition could also be caused by bad motor bearings, defective capacitor, and shrubs or other obstructions around the unit.Do you add refrigerant to the high or low side?The freon is added on the LOW PRESSURE SIDE ONLY. The hose tool you bought is made so you can only hook to the low side as the high side and low side fittings are different sizes and shapes for SAFETY’S SAKE.
