Carrier 38YKC030 Expansion Valve
Every air conditioning system contains an expansion valve that allows the coolant to expand into its normal low-pressure vaporous form from a liquid. The AC in a split system would not yield any cooled air if the valve was worn out.
Warnings the expansion valve needs a replacement ASAP
- The air conditioned air is definitely not as cold as it ought to be so as to feel comfortable in the house
- Your AC unit takes a really long time trying to cool the home
