Air conditioners don’t produce any oxygen. The air conditioner does not on its own generate oxygen. On the other hand, it may use a duct to bring in fresh air or outside air while also supplying oxygen to a room or structure. Residential air conditioners, fitted by AC companies in Folsom, CA, seldom require fresh air, but commercial buildings often have fresh air in their air conditioning system.
Some people believe that air conditioners create oxygen, but they do not and have an excellent reason not to.
