Goodman GKS90704CX Expansion Valve
An AC cannot possibly cool the house when lacking a functioning expansion valve. Pretty much every air conditioning system has an expansion valve that permits the refrigerant to spread back into vapor state from its highly pressured liquid form.
Simple signals the expansion valve is going to die
- AC unit takes too long in a bid to keep the home at a comfortably cold temperature
- The air conditioned flow is not cold enough as it really should be coming into the house
