What to expect at the repair shop when your Mercedes-Benz Sprinter 3500 has air conditioning problems

What will be the outcome of an air conditioning system diagnosis?

Replacement of most air conditioning components requires complete evacuation of the air conditioning system with a refrigerant recovery machine. Once components are re-installed, the technician will remove all air from the system in preparation for recharging the system with new refrigerant.

RepairPal Recommendations for air conditioning systems

Refrigerant is environmentally harmful, and should never be released into the air. Instead, a proper refrigerant recovery machine must be used to protect the technician, and the environment. We do not recommend attempting to recharge the A/C system at home, as products available to consumers tend to contain substances that can cause damage to expensive refrigerant recovery equipment. Lastly, if your vehicle has not been converted from R12 to R134a refrigerant, the best time to have this service completed is when the air conditioning system is already being serviced.

What to look out for with the air conditioning system

Refrigerant is a dangerous chemical that can cause severe chemical burns to the skin and eyes if improperly handled, and discharging into the atmosphere will cause damage to the ozone. Refrigerant types are updated over time, and the appropriate type must be used. If there has been an update or conversion from an older refrigerant type, a label should be placed under the hood to make your technician aware of the change. Depending on location, it may be illegal for a technician to replace refrigerant without updating the A/C system to handle the newest type.
