Carrier PB Expansion Valve
A split-system AC unit would most likely give you heated air if the valve was not functioning. Your home AC system contains an expansion valve that makes it easier for the refrigerant to expand into its normal low-pressure vaporous form from a high-pressure liquid form.
Cues of an ineffective AC expansion valve
- The air conditioned flow is warmer than it should be coming into the home
- AC takes a long time to bring down the temp in the house

If you are going to be buying or purchasing do your best and double check the correct model as well as make a visual comparison in order to be sure the correct replacement expansion valve is being ordered. If you are unsure about the properly replacing the expansion valve on your own then it may be wise to contact a professional to do the work for you.
