Whirlpool ATR0752RPP0 Expansion Valve
Almost all AC systems have an expansion valve that permits the refrigerant to expand back to its low-pressure vapor form from its highly pressured liquid form. Air conditioning units would be worthless if the valve was not doing its job.

- Cooled air is not cold enough as it should be in order to feel comfortable
- The cooling system takes forever in attempting to cool
