Carrier 38YKC048 Expansion Valve
Almost all AC systems have an expansion valve that makes it easier for the refrigerant to expand back to its low-pressure vaporous form from a high-pressure liquid form. The AC in an HVAC system would most likely give you heated air if the valve was not working.
What warnings should I watch out for to know if my main expansion valve is about to stop working?
- AC air production is not as cool as it should be coming from the AC
- Your AC takes its sweet time in a bid to keep the house cool as it should

Before buying or ordering any Carrier 38YKC048 part do your best and double check the model number as well as make a visual inspection in order to be sure the correct replacement expansion valve is the one being purchased. If you are not sure about the correct way of installing the new expansion valve by yourself then it may be wise to consult a pro to do the work for you.
