Carrier 48SS Expansion Valve
Your AC unit would not produce cooled air when lacking a functioning expansion valve. Every air conditioning system contains an expansion valve that allows the coolant to expand into its normal low-pressure vapor form from its highly pressured liquid form.
Symptoms of an inadequate main expansion valve
- AC unit takes its sweet time to appropriately keep things cool
- The cooled air is definitely not as cold as it ought to be coming from the vents
