Lennox CB30U-51 Expansion Valve
Air conditioning systems can not work right if the expansion valve was broken. A normal AC expansion valve makes it easier for the refrigerant to expand back to its low-pressure vapor form from a liquid.
Indications your refrigerant expansion valve is in need of replacing
- Cold air is well below the temp than the usual air comes through the ducts
- The cooling system takes too long trying to bring down the temperature
