If your fridge or AC is exposing you to trace amounts of TCE left over from the process of making the R134a it's primarily charged with, it also isn't keeping your food cold.
A common AC charge for a car is around 500g +/- 25g It doesn't take much of that leaking out before it doesn't blow cold air. Even if there was a bunch of residual TCE, you're unlikely to be subject to a long term exposure because you'd notice your AC or fridge not working long before the full charge leaked out to expose you.
In spite of the efforts of the world's accountants, fridges and air conditioners still routinely last a decade or more. That's because the charge of R134a is largely staying put.
