Goodman GSX130421 Expansion Valve
An expansion valve allows the refrigerant to expand into its normal low-pressure gas form from its highly pressured liquid form. Any air conditioner would be impossible to cool the home if it was deprived of a functioning expansion valve.
Clues of an ineffective refrigerant expansion valve
- Cold air is not as cold as it ought to be coming from the AC
- Your cooling system takes too long to comfortably keep the temperature down
