Samsung AVMBC040CA0 Expansion Valve
Expansion valves are used in AC systems and makes it easier for the refrigerant to expand back to its low-pressure vapor state from a high pressure liquid state. Your main AC unit would be worthless if the expansion valve was somehow damaged.
What are some hints that my expansion valve is in need of a replacement?
- Your AC unit takes too long in its attempt bring down the temp in the house
- Cold air is well below the temp you are accustomed to blowing from the vents
