International Comfort Products NNE075B12A1 Expansion Valve
An AC system cannot possibly cool the house if it were lacking a functioning expansion valve. Pretty much every air conditioning system has an expansion valve that allows the refrigerant to expand back into its natural vaporous form from a high-pressure liquid form.
How do you know if your main expansion valve is failing?
- AC takes way too long to bring down the temp in the house
- Cold air is much warmer than the usual air being blown into the house
