International Comfort Products T9MPD080J16A2 Expansion Valve
The AC in an HVAC system would not produce cooled air when lacking a functioning expansion valve. Pretty much every air conditioning system has an expansion valve that allows the refrigerant to expand back to its low-pressure gaseous form from a high-pressure liquid form.
Important signs the expansion valve will eventually need to be replaced
- Air from the AC is well below the temp than the usual air coming into the house
- AC unit takes a long time to keep the home at a comfortably cold temperature
