So mine must be a CO2... does that mean I'm an environmentalist or a filthy polluter?
Well you better decide soon if you are going to keep it.
Wait a year and if the unit goes belly up, you'll be looking for a hazmat crew to come by and remove the toxin filled heart with all that dangerous CO2. The call out, cleanup, and internment at the internationally certified bunker will set you back a few ducats. The author-o-tay will also probably level a large fine for buying the WMD monster in the first place.

Have a nice day! 🤪
