Carrier 42D Expansion Valve
The air conditioner for your house would be broken if the expansion valve was either damaged or just not working properly. Almost all AC systems have an expansion valve that makes it easier for the refrigerant to expand into its regular gaseous form from a high-pressure liquid form.
Symptoms your main expansion valve should be replaced
- Your AC takes too long trying to cool all the rooms in your house
- Cooled air is not as cool as it should be coming from the vents
