Carrier 38YCC042 Expansion Valve
Air conditioning units can not work right without a properly functioning valve. Your home AC system contains an expansion valve that permits the refrigerant to expand back to its low-pressure vaporous form from a liquid.
What are some indications that my Carrier expansion valve is about to stop working?
- The air conditioned air is well below the temp than the usual air for the AC to cool the house
- Your AC unit takes a long time in a bid to cool the home
