Goodman GMH80903BN Expansion Valve
An expansion valve permits the refrigerant to expand into its regular vapor form from a high-pressure liquid form. Air conditioning systems could not emit cold air if the valve was not functioning.
What warnings are present when my expansion valve is not working right?
- The outdoor AC unit takes a long time to actually keep the temperature down
- Cooled air is not cold enough as it used to be as it comes from the air conditioning unit
