Carrier 58CVX07010012 Expansion Valve
Your home AC system contains an expansion valve that allows the coolant to expand into its normal low-pressure vapor form from a liquid. Any home AC unit cannot possibly cool the house if it were to lack a properly working expansion valve.
Major clues of a defective AC expansion valve
- Your AC unit takes its sweet time in its effort to keep the house cool as it should
- Air from the AC is much warmer than it should be blowing through the ductwork
