    Some older units and even new ones have ammonia in the system. I've also seen the slight vapor while pulling a vacuum on an r22 unit. I've asked some more techs and no one has gotten nauseous from it.

    I'm not sure about this, but I will do some checking around and try to post back pretty quick. This makes me very curious as well.
