Carrier P3 Expansion Valve
An expansion valve facilitates in helping the refrigerant to spread back into vapor form from a liquid. Air conditioning units would probably be the worst AC in the world if the expansion valve was either damaged or just not working properly.
What signals that my AC expansion valve is in need of a replacement?
- AC unit takes too long in its effort to bring down the temp in the house
- The air conditioned air is warmer than it should be coming into the home
