Mitsubishi MSZ-GE09NA Expansion Valve
Pretty much every air conditioning system has an expansion valve that permits the refrigerant to expand back to its low-pressure gas state from a liquid. Your main AC unit cannot possibly cool the house when lacking a functioning expansion valve.
What to see if the refrigerant expansion valve is about to go out?
- AC air production is not as cold as you are accustomed to as it comes from the air conditioning unit
- Your AC unit takes its sweet time in a bid to bring down the temp in the house
