International Comfort Products HHP442AKA1 Expansion Valve
An air conditioner would most likely give you heated air if the expansion valve was either damaged or just not working properly. Pretty much every air conditioning system has an expansion valve that makes it easier for the refrigerant to expand into its regular vapor form from a high pressure liquid state.
Key signs of a poorly performing main expansion valve
- AC air production is definitely not as cold as you are accustomed to blowing from the vents
- Your cooling system takes a really long time to actually keep things cool
