Save a techs life story

You guys ever worked on any ammonia charged N.G. a/c units ?? Talking about something that will take your breath away !! Most if not all of these units that I use to service are gone due to the EPA regulations. I sure am glad to see them gone

I don't know about the newer ones. When I had to change out generators on the older units . there was no way to recover the ammonia. what my lungs didn't absorb went on the ground.Talk about a total vegetation killer !
