Carrier 48JZ Expansion Valve
Almost all AC systems have an expansion valve that makes it easier for the refrigerant to expand into its regular vapor state from its highly pressured liquid form. Your AC can not supply your house with cold air if the expansion valve was totally worn out.
Simple warnings that your expansion valve is crapping out?
- Air from the AC is well below the temp it should be being blown into the house
- The air conditioner takes its sweet time in attempting to keep the temperature down
