Nordyne E3EX-017H Expansion Valve
Pretty much every air conditioning system has an expansion valve that allows the coolant to expand into its normal low-pressure vapor state from its highly pressured liquid form. The AC in an HVAC system would be broken when lacking a functioning expansion valve.
How do you know when your main expansion valve needs replacing?
- The air conditioned air is much warmer than it should be being blown into the house
- The cooling system takes way too long in attempting to bring down the temperature
