The most serious side effects would occur at the time of exposure. Exposure to Freon may cause eye and skin irritation or sensitization. High concentrations of Freon cause severe depression of the central nervous system, weakness, dizziness, convulsions, and cardiac arrhythmia, irregular heart beat.

Fortunately, Freon does not have serious long term health consequences. When it is inhaled, it is rapidly excreted by exhalation, and it is not significantly accumulated in the body. This means that breathing low concentrations of freon from a leaking refrigerator or air conditioner over a long period of time is unlikely to have a cumulative effect, and thus few, if any, long term health effects.

Then again, the alleged damage to the ozone is why they quit allowing it in automobile use.
