Sanyo KHS2472 Expansion Valve
An AC would probably blow heated air if it were to lack a properly working expansion valve. Every air conditioning system contains an expansion valve that makes it easier for the refrigerant to expand into its regular vaporous form from a high-pressure liquid form.
What to see if the refrigerant expansion valve is failing?
- The cooled air is well below the temp you are accustomed to comes through the ducts
- AC takes too long to keep the home at a comfortably cold temperature
