Lennox CB30M-21 Expansion Valve
An expansion valve permits the refrigerant to expand back to its low-pressure vapor form from its highly pressured liquid form. The AC in your house would not produce cooled air if the expansion valve was either damaged or just not working properly.
Hints that your Lennox expansion valve needs replacing
- The air conditioner takes a long time in attempting to keep the house cool
- The cooled air is not cold enough as you are accustomed to as it comes from the air conditioning unit
