Do ac wall units let off co2?

I've heard that most wall mounted ac units let off co2. I'm getting my co2 tank hydrotested, but in the meantime I was wondering if my ac is letting off co2. If anybody knows.... please let me know.... Inquiring minds wish to know

I would assume that since all atmospheric air has co2 in it,and being that air conditioners cool atmospheric air, then I would say it's right to assume that said air also contains Carbon dioxide, though obviously not in the concentrations you get by using your co2 system.

if you mean does your window a/c suck out your c02. the answer is yes,it does.

you can try and seal it better though.

if your asking if it produces c02, the answer is no

no way in hell can an ac create co2. but their is a bunch of shit you can do to make it like viniger and baking soda, yeast, sugar and water mix and dry ice theirs probally more but thats all I can think of off the top of my head.

co2 is formed from chemical reactions or burning,an ac will never produce co2.
