Discussion:- does Air Conditional Releases Fresh Air/Bad gas

personally, I think there is a clear natural difference between air from A/C and fresh natural air. Abeg, any negative effect(s) with this A/c air because it has been too much for me oooo. Without A/c my boss can not stay... but the way its irritates me I can not tell... Pls is there health effect with this A/c? I believe that air is not natural...its a result of electrical and mechanical reaction.
