Automotive Ac System Evacuation

Non condensable gases have a serious impact on system performance operating conditions and lifetime of an air conditioning system.

Automotive ac system evacuation.

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

Car a c evacuation and recharge services. 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. Non condensable gases ambient air inside the a c system. A vacuum pump is used to draw the system to a vacuum of 29 75 hg or greater.

Performing an evacuation does not remove metal shavings from a system though this requires a flush. How long should i evacuate ac 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. 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.

Auto air conditioning systems need to be evacuated as part of routine maintenance when the system needs to be recharged. 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. 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. The best way to remove non condensable gases ncgs is to pull a deep vacuum in the system.

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.
