Lennox 13HPD-060 Expansion Valve
An expansion valve permits the refrigerant to expand into its regular vaporous form from a high-pressure liquid form. A split-system AC unit could not emit cold air if the valve was not doing its job.
What are the indications that my Lennox expansion valve is almost dead?
- The cold airflow is not as cold as it used to be blowing through the ductwork
- Your cooling system takes too long in its attempt keep the house cool
