FAQs
-
The most common reasons for the pressure gauge to indicate a red/high pressure reading are the car is not running, or the A/C is not on with the fan switch set to high and the temperature at its coldest setting. In order to obtain an accurate pressure reading the car must be running, the A/C set to the coldest position, and the fan setting set to high. Also, as the car’s compressor cycles on and off, the needle on the gauge will move in and out of the red/high pressure area of the gauge. This is normal. Here is an example of a car compressor cycling on and off:
-
Your system should be vacuumed if you have replaced a component part in the system, or if the pressure gauge indicates that the A/C system pressure is lower than 10psi.
-
When checking low-side pressure you will get two different pressure readings, one when the compressor cycles on and one when the compressor cycles off. Use the pressure reading when the compressor is cycled on and the system is operating at its highest settings (temp to max cold and fan on high). When the compressor cycles on you should see the needle on your pressure gauge begin to drop. When the compressor turns off you will see the needle move back to a higher pressure. Take the reading that occurs when the pressure is at its lowest point when the compressor is cycled on. To tell if your compressor is cycling properly, view the video below:
