Goodman GMS91155DXA 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 form. An AC would probably blow heated air if it were lacking a functioning expansion valve.
Key signs of a dying expansion valve
- The air conditioner takes a really long time in its bid to cool the indoors
- AC air production is warmer than it used to be being blown into the house
