Carrier 50ZH Expansion Valve
Every air conditioning system contains an expansion valve that facilitates in helping the refrigerant to expand back to its low-pressure gas state from a high pressure liquid state. The AC in your house would be impossible to cool the home if the expansion valve was broken.
Major clues your main expansion valve will eventually need to be replaced
- Air flow is not as cool as you are accustomed to so as to feel comfortable in the house
- The outdoor AC unit takes a long time to comfortably cool
