Air Conditioning Evac

At Global Automotive, can replace or repair most air conditioning components on your car. You must always evacuate the system before it can be recharged. Leave it to the pros at our shop. More info below:

  1. Moisture Removal: Moisture can be detrimental to the performance and longevity of an AC system. If moisture is present in the system, it can react with refrigerant to form acids, which can corrode components such as the compressor, condenser, and evaporator. Evacuation removes moisture from the system, minimizing the risk of damage.

  2. Air Removal: Air trapped in the AC system can cause inefficiencies and reduce cooling performance. Air contains oxygen and moisture, both of which can react with refrigerant and lead to corrosion and system damage. Evacuation removes air from the system, ensuring that only refrigerant is present.

  3. Refrigerant Recovery: Before evacuation, any remaining refrigerant in the AC system must be recovered. This is typically done using a refrigerant recovery machine, which safely removes the refrigerant and stores it for proper disposal or recycling. Recovering refrigerant is essential for environmental protection and compliance with regulations.

  4. Preparation for Recharging: After evacuation, the AC system is ready to be recharged with fresh refrigerant. Creating a vacuum in the system ensures that there are no leaks and that the refrigerant will flow properly throughout the system. This helps maximize cooling efficiency and performance.

The process of air conditioning evacuation typically involves the following steps:

  1. Preparation: The vehicle is raised on a lift or supported securely to provide access to the AC system components. The technician ensures that all necessary tools and equipment, including a refrigerant recovery machine and vacuum pump, are ready for use.

  2. Refrigerant Recovery: The technician connects the refrigerant recovery machine to the AC system’s service ports and begins the recovery process. The machine safely removes the refrigerant from the system and stores it in a recovery tank.

  3. Evacuation: Once the refrigerant is recovered, the technician connects a vacuum pump to the AC system’s service ports. The vacuum pump creates a vacuum within the system, removing air, moisture, and any remaining refrigerant. The system is typically evacuated for a specified period, typically around 30 minutes to ensure thorough removal of contaminants.

  4. Leak Testing: While the system is under vacuum, the technician may perform a leak test to check for any leaks in the AC system. This may involve using a leak detection dye or electronic leak detector to pinpoint the source of any leaks.

  5. Recharging: After evacuation and leak testing are complete, the AC system is ready to be recharged with fresh refrigerant. The technician connects a refrigerant charging hose to the service ports and adds the appropriate amount of refrigerant to the system according to manufacturer specifications.
