What is an expansion valve?
The expansion valve is mounted at the evaporator inlet and regulates the refrigerant going into the evaporator.
Most air conditioning technicians will automatically charge out the expansion valve as it's commonly a source of air conditioning failure. A good indication that your expansion valve has failed or is failing is a negative or high system gauge reading. This is either as a result of contaminants clogging the valve up or valvefailure.
