How can I get a static pressure reading on my car?
To find the static pressure reading for your car, attach to the hoses and gauge set to the high and low side ports of your AC system. 1. With the engine OFF for at least 30 minutes, read the low and high pressure gauges. 2. Measure ambient air temperature at the vehicle (do not use weather service temperatures) WITH A THERMOMETER.
What does 0 static pressure on AC mean?
What 0 static pressure means The entire AC system is empty due to a major leak. Find the problem before refilling. If static pressure is above the low pressure switch threshold
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.
What should the pressure be on the low side of the AC?
The pressure reading from the low side should be between 25 and 30 psi and the high side between 200 and 250 psi. But if you see the AC low side high, high side low, such as the low side is 100 and the high side is 150, there might be problems with any of the inner components.
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.
To find the static pressure reading for your car, attach to the hoses and gauge set to the high and low side ports of your AC system. 1. With the engine OFF for at least 30 minutes, read the low and high pressure gauges. 2. Measure ambient air temperature at the vehicle (do not use weather service temperatures) WITH A THERMOMETER.
What happens when the AC system pressure is too high?
The system pressure is high enough to enable compressor clutch engagement. If the static pressure is lower than 27-psi. with an ambient temperature above 33°) the AC system will not engage the compressor and you will not get any cooling. If the gauges aren’t the same during a static pressure test
An A/C System that is working properly should have 150 PSI on the high side and 30 PSI on the low side.
