2008 Chevrolet Trailblazer Air Conditioning Refrigerant Recover Cost

Recovery is necessary any time that the air conditioning system needs to be "opened," or disassembled. When the AC refrigerant lines are disconnected from other system components (the compressor, condensor, dryer, or evaporator), or from one another, refrigerant will escape forcefully from the system. This is a safety concern, an environmental concern, and a legal concern. Handling and storage of air conditioning refrigerants are regulated by the Environmental Protection Agency (EPA). It is illegal to knowingly discharge refrigerant into the atmosphere. It is also dangerous if the pressurized refrigerant sprays uncontrolled from a line as it is being disconnected.

A technician will use a special set of manifold gauges matched to the specific type of refrigerant in the vehicle to determine how much (if any) pressure is in the air conditioning system. Following a comprehensive evaluation of the entire system and diagnosis of component failure, the technician will use special equipment to evacuate or recover and store the refrigerant. When repairs are complete, the technician will recharge the system with fresh refrigerant, or possibly with the recovered/stored material.

To recover the refrigerant from a vehicle, a licensed and certified technician will connect hoses to both the high and low side connectors on the air conditioning system. The hoses are usually attached to a recovery and recharge machine. With the hoses connected and the hose valves open, the technician will set the machine to slowly remove the refrigerant from the vehicle and store it in a special canister. When the procedure is complete, the technician will verify that the system is indeed empty before proceeding with repairs.

RepairPal recommends that the air conditioning system be serviced by a licensed and certified professional who will use the proper procedures and equipment to recover the refrigerant in a vehicle. A technician must be certified under Section 608 by the EPA in order to lawfully recover, store, purchase, and install refrigerant.

Air conditioning refrigerant is under pressure and can cause severe injury if it escapes during an improper repair/recovery procedure. Different types of refrigerant have been used over the years in vehicles. It is necessary to know what type of refrigerant is used and to have access to the proper equipment for that type of material.

Automotive air conditioning refrigerant recovery should be performed only by a licensed and certified (EPA Section 608) technician using the proper equipment specific to the type of refrigerant being recovered. A professional has the ability to perform a comprehensive evaluation of the entire air conditioning system, diagnose any problems, and complete the appropriate repairs. And a professional will have access to appropriate replacement materials. Some of the products available to consumers, while compatible with the OEM refrigerants, are not the same materials that were installed by the manufacturer. DIY service of the air conditioning system may yield less than satisfactory results and can lead to damage to system components. A common DIY mistake is over- or under-charging the system, which may lead to insufficient cooling ability and premature failure of the AC compressor.
