Lennox 12CHP036 Expansion Valve
A normal AC expansion valve permits the refrigerant to spread back into vapor state from a high pressure liquid state. An AC would be worthless if the expansion valve was somehow damaged.
Major signs that your Lennox expansion valve needs a replacement ASAP
- The cool flow of air is much warmer than it used to be exiting the air handler
- AC takes way too long to actually bring down the temperature
