Friedrich MW09Y3H Expansion Valve
An expansion valve allows the refrigerant to expand back into gaseous form from a liquid. Any home AC unit would produce no cooled air if it were to lack a properly working expansion valve.
Key symptoms of an ineffective main expansion valve
- The cool flow of air is not cold enough as than the usual air streaming from the vents
- The outdoor AC unit takes a really long time to actually keep the house cool
