Goodman ARUF374316 Expansion Valve
An air conditioning system can not work right if the valve was not working. Your HVAC system expansion valve makes it easier for the refrigerant to expand into its normal low-pressure gas form from its highly pressured liquid form.
Clues of a declining main expansion valve
- Air from the AC is warmer than it ought to be coming from the vents
- Your AC unit takes way too long in attempting to bring down the temperature
