Carrier 38YCG042 Expansion Valve
The AC in an HVAC system can not work right if it were lacking a functioning expansion valve. An expansion valve permits the refrigerant to spread back into vaporous form from a liquid.
Red flags the expansion valve is on its last leg
- The cool flow of air is not as cold as it used to be coming out of the vents
- The outdoor AC unit takes forever to appropriately keep the house cool
