NewAir AC-14100E Expansion Valve
Almost all AC systems have an expansion valve that allows the refrigerant to spread back into gaseous form from a liquid. An AC system could not work if it was deprived of a functioning expansion valve.

- Air flow is warmer than you are accustomed to coming from the air handler
- Your cooling system takes a long time to properly bring down the temperature
