What causes a high head pressure?
What causes a high head pressure? The air and water vapor will pass through the evaporator and compressor because the compressor is a vapor pump. Once the air gets to the condenser, it will remain at its top and not condense. This air and water vapor will take up valuable condenser surface area and cause high-head pressures. Why is my AC high side pressure not correct? The correct reading will display once the clutch engages and the gauge stops cycling. If there are readings on both the high and low sides but they are not the correct specified pressures, it...
