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.

Automotive ac system evacuation.

The automotive a c system must hold the vacuum of 29 92 in hg for at. Evacuating or discharging an automobile auto air conditioning system ac is a simple process provided the necessary tools are available. 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. Non condensable gases ambient air inside the a c system.

Performing an evacuation does not remove metal shavings from a system though this requires a flush. Non condensable gases in most cases surrounding ambient air are not able to condense inside the air conditioning condenser unlike refrigerant gases like r 134a or r 1234yf. A vacuum pump is used to draw the system to a vacuum of 29 75 hg or greater. 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.

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. A c evacuation and recharge. 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. 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.

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. The best way to remove non condensable gases ncgs is to pull a deep vacuum in the system. How long should i evacuate ac system. Car a c evacuation and recharge services.
