Why does my AC pressure read too high?
Finally, if you’re wondering why your AC pressure reads too high on the low pressure side, while the high side pressure remains normal, you might be dealing with incorrect cycling of the condenser. This happens when there is an unusually rapid cutting in and out of the cycle.
What should my AC low side pressure be?
When the engine is on and the AC is on high, low pressure readings should be around 30 psi and the high pressure side should be about 250 psi depending on your car. The correct reading will display once the clutch engages and the gauge stops cycling.
What should my car AC pressure reading be?
When testing your car’s AC system pressure, make sure to proceed carefully, follow instructions properly, and use your car manual as a guide on what you should expect the readings to be for your vehicle. One of the most common issues you may have when it comes to your AC system is leakage.
How can I check the low side of my AC?
If you want to easily check the pressure readings of your AC system, a simple way to do it is by using a pressure gauge, which you can buy for a cheap price at your local shop or from online stores like Amazon. Just follow the user instructions of the pressure gauge to read your AC’s high side and low side pressure.

What should the PSI be on an A / C system?
An A/C System that is working properly should have 150 PSI on the high side and 30 PSI on the low side.
When the engine is on and the AC is on high, low pressure readings should be around 30 psi and the high pressure side should be about 250 psi depending on your car. The correct reading will display once the clutch engages and the gauge stops cycling.
What are my a / C pressure readings telling me about my an / C?
200 PSI / 70 PSI = There is a blockage somewhere in your system either before or at the expansion device. 160 PSI / 10 PSI = It is possible that the evaporator is frosted, the low pressure piping is faulty, or the expansion valve might be clogged.
