Amcor AWS240HR Expansion Valve
Almost all AC systems have an expansion valve that facilitates in helping the refrigerant to expand back to its low-pressure vapor form from its highly pressured liquid form. Your AC unit would not produce cooled air if the valve was not doing its job.
Signs your main expansion valve will soon need to be replaced
- Your cooling system takes a long time to actually keep the house cool as it should
- The cool flow of air is much warmer than it really should be streaming from the vents
