Automotive Ac System Evacuation

This debris will be the broken parts of compressor reed valves piston rings maybe even parts of a disintegrated piston and metallic scrapings from internal cylinders.

Automotive ac system evacuation.

Auto air conditioning systems may require flushing after a catastrophic failure of the compressor since debris from the failed unit can scatter throughout the closed system. The best way to remove non condensable gases ncgs is to pull a deep vacuum in the system. We then inspect the car a c system s pressure and temperature control to make sure everything is working correctly for a car air conditioner recharge service. How does air or.

A c evacuation and recharge. Evacuating or discharging an automobile auto air conditioning system ac is a simple process provided the necessary tools are available. By bringing a closed system into a vacuum the boiling point is greatly reduced and any moisture boils into a vapor that s pulled out through the vacuum pump. We offer an a c evacuate and recharge where we void the air conditioning system of old refrigerant and then recharge the system with new refrigerant.

A vacuum pump is used to draw the system to a vacuum of 29 75 hg or greater. When an air conditioning system loses its ability to cool properly it may be necessary to recharge the system with new refrigerant keep reading for a r 134a a c pressure chart and steps on how to recharge the a c system when the system is low on pressure or has been vacuumed out following a repair. After a system has been opened for any repair service or installation even for a short amount of time the a c system should be evacuated. How long should i evacuate ac system.

Auto air conditioning systems need to be evacuated as part of routine maintenance when the system needs to be recharged. Non condensable gases have a serious impact on system performance operating conditions and lifetime of an air conditioning system. If no leaks or damage are found they evacuate the refrigerant from the system vacuum test and recharge the air conditioning system using the appropriate refrigerant according to your vehicle manufacturer s specification. The automotive a c system must hold the vacuum of 29 92 in hg for at.

Performing an evacuation does not remove metal shavings from a system though this requires a flush.
