R22 (commonly referred to by the brand Freon) is not a toxic substance. Its main danger would be the potential for oxygen displacement just as any other gas that is heavier than air, causing symptoms of asphyxiation. Some people may be highly sensitive to environmental substances in general, and have an asthmatic type response to R22. In the scope of a home system for example, unless the system is leaking the better portion of its charge in a matter of a day or two, there is no danger to the home or inhabitants. In rare cases, very rare, ammonia or an uncommon refrigerant could be used, but the majority of home A/C's for generations have been R22.

Is a freon leak harmful to the environment?

An AC unit in our office leaked freon. In order to repair the unit, the mechnaic had to weld the unit to avoid continuous leaks going forward. The employees in the office were concerned the freon leak could be harmful to the office air/environment. Is this something we should be concerned about or once cleaned up and repaired is there no longer an issue? A: In terms of your immediate health, no. Freon is not dangerous other than that it can suffocate you like any other gas if it displaces the oxygen in the room. This would require a significant leak in a closed room with poor circulation. Since you're asking the question, I assume you survived... In terms of the environment, some freons destroy the ozone layer and most freons are VERY potent greenhouse gases. So yes, they can create environmental problems, but no, they are not dangerous in a sense of being toxic.
