International Comfort Products HAC448AKA1 Expansion Valve
Your HVAC system expansion valve makes it easier for the refrigerant to expand back to its low-pressure gas state from a high pressure liquid state. The AC in a split system could not work if the expansion valve was somehow damaged.
What are some hints that my main expansion valve is crapping out?
- AC unit takes forever to appropriately bring down the temp in the house
- The air is well below the temp it should be blowing through the ductwork
