International Comfort Products HAC048GKA4 Expansion Valve
Pretty much every air conditioning system has an expansion valve that facilitates in helping the refrigerant to expand back to its low-pressure vaporous form from a liquid. Air conditioning units would probably blow heated air if the expansion valve was totally worn out.
Warnings the expansion valve is failing
- Cooled air is warmer than it used to be so as to feel comfortable in the house
- AC unit takes a really long time in its bid to keep the temperature down
