The Car Care Council recommends having your vehicle's heating, ventilation and air-conditioning unit inspected once a year by a certified mechanic to keep the refrigerant at the proper level and check for leaks and worn or faulty belts. Get your air conditioner serviced immediately if you notice any of the following warning signs:

  • Excessive water under the engine. Minor drips may be due to normal condensation.
  • Wet carpets. Auto air conditioners are built with a drain that gets rid of water below the vehicle. If the drain gets clogged, you may end up with water inside the vehicle.
  • A musty smell coming from your car's air vents.
  • Strange sounds (squealing, buzzing, knocking) coming from the air-conditioning unit.
