What Can I Do to Protect the Ozone Layer?

Go only to service facilities with EPA-certified technicians
Make sure refrigerants from your vehicle will be recovered and recycled during servicing
Repair all leaks in the a/c system (not required by federal law, but helpful in protecting the ozone layer): Although not required by federal law, this is one of the single best ways to do your part to protect the ozone layer. About 20-30 million cars on the road today use CFC refrigerants in their air-conditioning (AC) systems. If leaky systems were repaired, it would prevent the release of millions of pounds of CFCs into the atmosphere each year.
If your air conditioner needs major repairs, talk to your certified service professional about having it converted to use an alternative refrigerant.

Repair air conditioners: Although not required by federal law, this step prevents ozone-depleting refrigerants from escaping. Make certain the refrigerant is recovered before servicing. See a fact sheet on this topic.
If you purchase a new A/C system or heat pump, purchase one that uses non-ozone-depleting refrigerant. See a fact sheet on this topic.
Remove the refrigerant from refrigerators, air conditioners, and dehumidifiers before disposing of them: Removing the refrigerant before disposal of old refrigerators alone would prevent the release of about 4 million pounds of CFCs each year. The used refrigerant can be recycled and reused. Ask your local government or waste hauler if the refrigerant will be removed before the appliance is discarded.
Make sure your service technician is EPA certified.
Work with local officials: Help start a refrigerant recovery and recycling program in your area if none exists. Not only will a responsible appliance disposal help to protect the ozone layer, but the recovered CFC-12 from appliances can be resold, helping to recoup a portion of the costs of the program.

If you suspect or witness unlawful releases of refrigerant or other violations of the Clean Air Act regulations, you can file a report easily and anonymously by visiting EPA's Office of Enforcement and Compliance Assurance website.
