What should the low side of the air conditioner pressure be?
The low side pressure in your air conditioning system should drop down significantly when your engine is running and your AC compressor is cycling on. When the compressor shuts off or you turn your car off the pressures in the system will equalize between the high and low side so the low side pressure will read much higher.
Where is the low pressure air conditioner Charger?
The first step in recharging your system is to locate the low side service port (or low-pressure port). Every auto air conditioning system has two service ports: one on the high pressure and one on the low pressure side. When recharging with AC Avalanche refrigerant, for safety, you will charge through the low side service port.
Where is the low side service port on an air conditioner?
Every auto air conditioning system has two service ports: one on the high pressure and one on the low pressure side. When recharging with AC Avalanche refrigerant, for safety, you will charge through the low side service port. Never charge through the high side port.
How does a high pressure AC system work?
To measure the pressure in the high-pressure side of your system, you need a little fancier piece of equipment. The pressures in the high-pressure side of your system are so high that it requires special hoses and connections along with a special gauge to contain the pressure and ensure you don’t release any of the refrigerant to the atmosphere.
What should AC low side high side low pressure be?
On the other hand, there is possibly a huge leak when the pressure is zero. AC Low Side High, High Side Low: Why Does This Happen? The pressure reading from the low side should be between 25 and 30 psi and the high side between 200 and 250 psi.
Where do I find low head pressure on my air conditioner?
We also provide a MASTER INDEX to this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need. Low head pressure may occur simulataneously with high pressure on the suction side of an air conditioner, heat pump or refrigeration system compressor system.

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.
