EPA Certification

The EPA under the Clean Air Act requires individuals working on refrigeration equipment, including residential air conditioning units, to be certified in the proper handling of "ozone-depleting" substances. This is a mandatory program and all technicians are required to pass an EPA-approved test. There are four levels of certification. Type I Certification covers household appliances, Type II covers high and very high-pressure equipment, Type III covers low-pressure equipment and the Universal certification covers all of the above.

It is illegal and punishable by significant fines to vent Freon, the most common substance used in residential air conditioning equipment, to the open air. The prohibition on venting covers maintenance, servicing, repair and disposal of air-conditioning or refrigeration equipment. The technician servicing your unit must know how and have the proper equipment, to recapture any Freon in the system.
