Vehicle Maintenance

Air Conditioner

• Many older auto air conditioners contain chemical refrigerants that can harm the atmosphere.
• Pre-1995 models used about 3 pounds of chlorofluorocarbons (CFC-12 also known as Freon).
• When CFC’s leak out, they damage the stratospheric ozone layer.
• 1995 or newer models, most likely contain HFCs (hydrofluorocarbons).
• HFCs do not damage the stratospheric ozone layer but do contribute to climate change.
• Have a trained mechanic look for leaks each time the vehicle gets a tune up.
