It’s a good idea to hook your compressor up to a pressure gauge if you don’t know which component is causing the problem. The high and low sides of the A/C system should have the same amount of air pressure.

What should my AC pressures be?
The low-side should be in the 30s or low 40s. There’s a problem if the pressure is too low or high. High-side pressure is more than double the ambient temperature and 50 PSI.
What should the high and low side pressures be?
Ideally, you want to see your low side pressure between 30 to 40 psi and your high side pressure between 150 to 175psi.
Is 40 psi too much for AC?
The low-pressure gauge should be between 25 and 40 pounds per square inch, and the high pressure gauge should be between225 and 250 pounds per square inch.
What should R134A pressures be?
The best running pressure for R134A in newer cars is between 22 and 57 pounds per square inch.
Why is my AC pressure so high?
AC issues can be caused by overcharging the system or leaking. The use of wrong compressor lubricant, loose wiring, and low or old oil in the system are some of the issues that could be.
Why is my low side AC pressure so high?
The system can’t cool down the car if the AC low side pressure is too high. There are a number of possibilities for this situation. It’s possible that it’s a leak in the system or that the compressor has been added to charge the AC.
Why is my high side AC pressure too high?
An obstruction in the evaporator is the most common cause of high pressure on both high and low pressure AC sides. It could be a simple debris that can be cleaned if removed, or it could be due to internal damage.
Do you check AC pressure with car running?
Do you check the AC pressure when the car is running? You should not do this because you will not get the right reading.
Can you put too much refrigerant car AC?
It can seem counterintuitive, but too much heat and pressure in your car’s AC system can cause you to blow out your hair. If the AC system in your car is over charged, it can damage the compressor.
What Should low side pressure be 410A?
If the air conditioning system had R-410A, the pressure on the low side of the system will be between 102 and 145 PSIG, no matter what the heat load is.
What does it mean when AC low side pressure too high?
The system can’t cool down the car if the AC low side pressure is too high. There are a number of possibilities for this situation. It’s possible that it’s a leak in the system or that the compressor has been added to charge the AC.
