Heating and Air Conditioning (HVAC)

Your vehicle is equipped with a highly sophisticated heating, ventilation, and air conditioning system (HVAC) that maintains a clean and comfortable atmosphere within the vehicle. A well-functioning HVAC system will not only optimize climate control and defroster operation, it will help maintain the MPG rating over the life of the vehicle. Regular checks and preventative maintenance (e.g., cabin filter, A/C compressor) will keep the A/C system doing its job and help prevent potential costly repairs.

The most important thing to know about maintaining your HVAC system is that only trained technicians use the proper equipment, components, and procedures to repair and diagnose potential issues. For example, if you drive your vehicle in a consistently humid climate, you may wish to ask your service advisor at ADVANCED AUTO DIAGNOSTICS about Terraclean treatments, to eliminate odors or mold build-up.

General Care Tips

  • The refrigerant used in your vehicle’s air conditioning system may adversely impact the environment if disposed of improperly. At ADVANCED AUTO DIAGNOSTICS technicians will use specialized recovery and recycling equipment to safely handle its disposal.
  • Your car’s 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 in your European or Domestic vehicle relies on proper belt tension and serpentine belt condition. Our professional service technicians will check the conditions of all air conditioning and heating components to avoid unnecessary breakdowns.

Seasonal HVAC inspections are recommended as part of overall vehicle care and maintenance. Watch for notices you may receive from ADVANCED AUTO DIAGNOSTICS regarding inspections, as they are aware of the proper timing for your vehicle.

Common Symptoms

  • My car is throwing cold air from the driver side and warm air from the passenger side.
  • A/C is not blowing air through the vents in my car at all.
  • A/C speed control is not working only on low and high.
  • A/C is cold when the car starts in cold but when I start driving A/C gets hot.
  • A/C is blowing hot air.

All of these issues you might have in your BMW, Mercedes Benz, Mini Cooper, Land Rover, Audi, ETC are handled by our specialist A/C Technicians at Advanced Auto Diagnostics.

I am 55 years old and not a fan of the “online” world but I felt compelled to put a review for these guys. I must thank David and the staff behind him for their honesty and integrity. They saved me around $3,000 in unnecessary repairs that were suggested by my dealer!!! I ran these guys through 2 honesty tests and they passed with flying colors. Good people still exist !!!!
