International Comfort Products H9MPD050F12A1 Expansion Valve
An AC would most likely give you heated air if the valve was not doing its job. Almost all AC systems have an expansion valve that makes it easier for the refrigerant to expand back into its natural vaporous form from a high-pressure liquid form.
Signals your main expansion valve is in need of replacing
- The cold airflow is warmer than it used to be exiting the vents
- Your AC takes too long to actually keep the home at a comfortably cold temperature
