Mitsubishi MSY-A24NA Expansion Valve
The AC in an HVAC system can not run if the expansion valve was worn out. Pretty much every air conditioning system has an expansion valve that allows the refrigerant to expand back into its natural gas form from a high pressure liquid state.
Key indicators that my expansion valve has to be replaced?
- Air flow is much warmer than you are accustomed to exiting the air handler
- The cooling system takes way too long to properly cool the house down
