Friedrich MW36C3G Expansion Valve
Every air conditioning system contains an expansion valve that allows the refrigerant to expand into its normal low-pressure gas form from a liquid. Any home AC unit could not cool the air if it was deprived of a functioning expansion valve.
What symptoms are present when the main expansion valve is dying?
- The air is not as cold as it used to be coming into the home
- Your AC takes a long time to actually cool
