International Comfort Products FBF075B12A3 Expansion Valve
An AC system would not yield any cooled air without a working expansion valve. A normal AC expansion valve allows the coolant to expand into its normal low-pressure vapor form from a high pressure liquid state.
Important hints your main expansion valve is going out
- Cold air is well below the temp you are accustomed to in order to feel comfortable
- The outdoor AC unit takes too long in attempting to keep the house cool
