Carrier 58MSA120 Expansion Valve
Almost all AC systems have an expansion valve that permits the refrigerant to expand back to its low-pressure vapor state from a high pressure liquid state. An air conditioning system would be worthless if it were to lack a properly working expansion valve.
Clues of a laboring AC expansion valve
- The cooling system takes a long time to comfortably cool the home
- The cold airflow is not as cool as you are accustomed to blowing from the vents
