Air Conditioning

Heating and Air Conditioning (HVAC)

A well-functioning heating, ventilation, and air conditioning (HVAC) system not only optimizes climate control and defroster operation, it can help maintain MPG rating over the life of the vehicle. Regular checks and preventative maintenance (e.g., cabin filter, A/C compressor) performed with genuine Mercedes-Benz parts can prevent potential costly repairs.

The most important thing to know about your HVAC system is that only Mercedes-Benz trained technicians use the proper equipment, components, and procedures to repair and diagnose potential issues. For example, if you drive your vehicle in a humid climate, ask your Mercedes-Benz service advisor about special cleaning and drying treatments that eliminate odors and mold build-up.

General Care Tips

  • The refrigerant used in your air conditioning system may adversely impact the environment if improperly disposed of. Our technicians will use specialized recovery and recycling equipment to safely handle its disposal.
  • Your HVAC system requires the smooth flow of air through clean vents to function properly. Have the cabin filters inspected and changed regularly.
  • The operation of the A/C compressor relies on proper belt condition and tension. If a replacement is needed, a genuine Mercedes-Benz belt assures for a perfect fit.
  • Seasonal HVAC inspections are recommended as part of overall vehicle care and maintenance. Watch for notices from your dealership regarding inspections, as they are aware of the proper timing for your vehicle.
