Lennox 13HPD-042 Expansion Valve
Almost all AC systems have an expansion valve that allows the refrigerant to expand back into its natural vapor form from a liquid. An AC would not yield any cooled air if it was deprived of a functioning expansion valve.
Simple warnings that your AC expansion valve is almost dead?
- The outdoor AC unit takes its sweet time to cool as it should
- The air conditioned air is definitely not as cold as it ought to be for the AC to cool the house
