What does static pressure on an AC system mean?
Static pressure is the pressure with the system at rest (compressor off for at least 30-mins). Attach to the hoses and gauge set to the high and low side ports of your AC system.
What should the pressure be on my a / C compressor?

Why is my air conditioner compressor cycling on and off?
The air conditioner compressor was rapidly cycling on and off. I turned the A/C off and stopped putting R-134a into it becuase the compressor cycling was almost causing the car to die from the load it was putting on the engine. Onto Google I went.
What should the PSI be on an A / C system?

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.
What does it mean when your air conditioner is short cycling?
Definition of Air Conditioner Short Cycling Short cycling means that your air conditioner turns off and on too often, too rapidly, or at irregular intervals.
