Carrier RHR Expansion Valve
Expansion valves are used in AC systems and makes it easier for the refrigerant to expand back to its low-pressure gas state from a high pressure liquid state. Your air conditioner can not deliver properly cooled air without a working expansion valve.
Key clues of a bad refrigerant expansion valve
- Your cooling system takes way too long in attempting to cool all the rooms in your house
- Air flow is warmer than it should be in order to feel comfortable
