Auto AC Flush Vs Vacuum

A vehicles air conditioning (AC) cooling system will not work properly if certain conditions are not met. An auto AC flush and vacuum are two methods of ridding a vehicles cooling system of substances harmful to its operation.

Flush

Debris in a vehicles AC system can cause blockage ultimately affecting its cooling performance. Flushing is a way to remove this harmful debris from the system. Flushing also completely removes oil from an AC system. Flushing should always be done when replacing an AC compressor.

Vacuum

After an AC compressor replacement, the AC system needs to be thoroughly vacuumed using a vacuum pump. The pump removes unwanted moisture and air from the system. Air is removed because it can lower the AC systems cooling abilities, while moisture is removed because it can cause the expansion valve to freeze.

Tips

After flushing an AC system, filters should be installed to prevent left over debris from getting back into the system. During the vacuum process, a device called a thermistor vacuum gauge can help verify all air and moisture have indeed been removed from the system.
