Lennox CBX32M-018 Expansion Valve
Your main AC unit could not run if it were lacking a functioning expansion valve. Every air conditioning system contains an expansion valve that allows the coolant to expand back into its natural gas state from a high pressure liquid state.
Some warnings the AC expansion valve should be replaced
- The air conditioner takes its sweet time to actually cool the indoors
- The air conditioned flow is warmer than it used to be being blown into the house
