International Comfort Products C8DNL100L20B1 Expansion Valve
The AC in a split system would be worthless if the valve was not doing its job. Every air conditioning system contains an expansion valve that allows the refrigerant to expand back into its natural vapor state from its highly pressured liquid form.
What to see if the main expansion valve really needs to be replaced?
- The cooling system takes forever trying to bring down the temperature
- Cooled air is well below the temp it really should be coming out of the vents
