The don't.

 Freon, is non-polar, water is polar.  I bit like trying to mix water & oil. If you are talking about an automotive air conditioner, you want only coolant circulating.  Air reduces efficiency, as does wter vapour.  Water would also freeze.

I was told that some type of acid would form...

R-134a or R-12 will not absorb water.
Any water / vapour will cuase corrosion in the system causing eventual compressor failure.
All systems are are vacume pumped & purged with refrigerant to ensure that no water / vapour is present in the system before refrigerant is added.

Just a thought and perhaps I am wrong.  Freon isn't used anymore.  I am not sure of the type of refrigerant used today but I know that it can be different depending on the year of the car.  So it's possible that different refrigerants will have different properties.  Someone with more knowledge of this may have a better idea.  But alos, as Malmensa said, water would likely freeze and that would be very bad.

freon will not mix with water, the oil in compressor systems will form a gummy goo sometimes.
Freon, burning will form bad things, including things that mixed with water will form an acid or a base depending on which of the groups of fluorocarbons, or chlorofluorocarbons...

but they when released suddenly will form ice, as the expansion from liquid or high pressure to a low pressure absorbs energy from the surrounding liquid.

Freon 12 is Dichlorodifluoromethane and contains chlorine, if burned would produce chlorine gas, that mixed with water would be a base, what a way to create bleach?  aqueous CL2?

Don't go burning the stuff is my advice.

yes, suffocation thru drowning in your own fluids. (Chlorine gas was used as chemical weapon during the first world war, not stuff you want to mess with)

As with most things at these pressures, if you don't know what you are doing, don't screw around with it.

at these pressures, freon can puncture you skin, sending bubbles of fluorocarbon into your veins along with the lubricating oils wreaking havoc with your internal organs causing pain, or even death.

Don't screw with pressurized systems, including hydrolic systems as they have lethal potential.

Freon heated though a cigarette wil decompose to create PHOSGENE! This is a highly toxic compound, used as a WMD  in WW1. Best avoided.
