Carrier 58CTA07010012 Expansion Valve
An air conditioning system cannot possibly cool the house if the expansion valve was totally worn out. Your home AC system contains an expansion valve that allows the coolant to expand back into vapor form from a high-pressure liquid form.
Key signs of a bad main expansion valve
- The cool flow of air is warmer than it really should be coming from the AC
- The outdoor AC unit takes way too long trying to cool your home
