The A/C expansion valve is crucial because it helps control the flow of the refrigerant in the A/C system. Also, it makes sure that the system runs as smoothly as possible.
A/C expansion valve functionThe A/C expansion valve has different roles that make the vehicle run as smoothly as possible. It controls the drop in pressure, the rate of travel of the fluid, and the evaporator output temperature. The A/C expansion valve is installed with a tube and the valve guarantees that sufficient refrigerant is traveling via the loop.
For the cooler air to travel around the cabin, air must get rid of heat and moisture. To accomplish that, the refrigerant must pass through the high-pressure and low-pressure ends. Also, the expansion valve may fail over time because of high pressure and extreme temperatures.
Common issues with a faulty AC expansion valveA faulty AC expansion valve can cause erratic cabin temperatures and a decline in A/C performance.
