International Comfort Products GNJ075N12A1 Expansion Valve
Pretty much every air conditioning system has an expansion valve that allows the coolant to expand into its regular vaporous form from a liquid. The AC in a split system would be impossible to cool the home if the valve was not doing its job.
What are the indications that my refrigerant expansion valve is not working properly?
- AC air production is well below the temp it really should be coming into the house
- Your AC takes a long time in its attempt cool all the rooms in your house
