Lennox 13ACD-036 Expansion Valve
Every air conditioning system contains an expansion valve that makes it easier for the refrigerant to expand back to its low-pressure vapor state from a high-pressure liquid form. Air conditioning systems can not run if the valve was not doing its job.
Key symptoms to watch for in a bad refrigerant expansion valve
- The air conditioned flow is not cold enough as than the usual air so as to feel comfortable in the house
- AC unit takes forever in attempting to keep things cool
