Lennox HP13-024 Expansion Valve
Air conditioning units would produce no cooled air without the valve working properly. Expansion valves are used in AC systems and allows the refrigerant to expand into its normal low-pressure gas form from a high-pressure liquid form.
What warnings should I watch out for to know if my main expansion valve is in need of a replacement?
- Air flow is warmer than it really should be for the AC to cool the house
- Your AC unit takes its sweet time to cool the house down
