International Comfort Products NNE075B12G1 Expansion Valve
Every air conditioning system contains an expansion valve that allows the coolant to expand back to its low-pressure gas state from a liquid. Any air conditioner can not run if it were lacking a functioning expansion valve.
What to see if the refrigerant expansion valve is dying?
- The outdoor AC unit takes forever in attempting to cool as it should
- The air conditioned air is not cold enough as it should be exiting the air handler
