International Comfort Products CAC224GKA1 Expansion Valve
Every air conditioning system contains an expansion valve that allows the coolant to expand into its regular gas state from its highly pressured liquid form. A split-system AC unit would probably blow heated air when lacking a functioning expansion valve.
Hints your main expansion valve needs replacing
- The outdoor AC unit takes its sweet time in its effort to bring down the temp in the house
- The cool flow of air is not as cold as you are accustomed to blowing from the vents
