Carrier KFCEH1101C10 Expansion Valve
A split-system AC unit would produce no cooled air without a working expansion valve. Every air conditioning system contains an expansion valve that allows the coolant to expand back into vaporous form from its highly pressured liquid form.
What warnings should I watch out for to know if my refrigerant expansion valve is almost going bad?
- AC unit takes a long time to appropriately keep the temperature down
- Air flow is well below the temp it should be in order to feel comfortable
