Although mechanics tell owners that the high pressure is due to a problem with the accumulator or evaporator that is not likely the case. One side of the ac system is low pressure, where the refrigerant starts out as a gas;

If both of your numbers are in these ranges, then everything is working the way it should be and you shouldn't have too much to worry about in terms of your ac system. The technician should have the right tools and information about the a/c compressor. Actual readings will vary according to ambient temperature.

And the other is a high pressure, where it is converted into liquid form so that it can flow through the system.both sides of the system work together to keep. The correct reading will display once the clutch engages and the gauge stops cycling. 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.

This Is Due To Air Condensing Inside A Tire Due To The Temperature Drop.

If you are using a low pressure gauge when the low pressure reading is between 25 psi and 40 psi, the system is fully charged. The pressure gauges for this refrigerant stays between 22 psi and 57 psi (pounds per square inch). Start the engine and turn on the air conditioner.

Use Your Air Conditioning Gauge Set To Check For Adequate Levels On Both Sides.

Pressure that is too much lower or higher shows there is a problem. Car tyre pressure refers to the amount of air that has been pumped into the inner linings of your tyres. 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.

The ac pressure switch is one of the relatively cheap parts. 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 pressure chart plays a vital role in identifying the problem in an a/c compressor unit.
