Samsung UH070CAV Expansion Valve
Almost all AC systems have an expansion valve that allows the refrigerant to expand back to its low-pressure vapor form from its highly pressured liquid form. Your AC unit can not deliver properly cooled air if the valve was worn out.
Subtle hints your refrigerant expansion valve needs replacing ASAP
- Air from the AC is not cold enough as you are accustomed to as it comes from the air conditioning unit
- Your AC takes way too long in attempting to cool the indoors
