Lennox G40DF-48B-070 Expansion Valve
An AC would be impossible to cool the home if the expansion valve was totally worn out. Expansion valves are used in AC systems and allows the refrigerant to expand into its normal low-pressure vapor form from a liquid.
What happens when my refrigerant expansion valve is not working properly?
- The cold airflow is well below the temp you are accustomed to so as to feel comfortable in the house
- Your AC unit takes too long to appropriately keep things cool
