EdgeStar AP12000S Expansion Valve
An expansion valve allows the refrigerant to expand back into its natural gaseous form from a high pressure liquid state. Any home AC unit can not supply your house with cold air if the expansion valve was totally worn out.
General warnings poorly running expansion valve
- The air conditioned air is much warmer than it really should be blowing through the ductwork
- The air conditioner takes too long to actually keep the home at a comfortably cold temperature
