Carrier 38TXA030 Expansion Valve
Your home AC system contains an expansion valve that makes it easier for the refrigerant to expand back into gas form from a liquid. An AC would most likely give you heated air if the valve was worn out.
Some warnings of an unhealthy refrigerant expansion valve
- Cold air is not as cold as it used to be for the AC to cool the house
- AC unit takes too long in its bid to keep the temperature down
