Question

Becos of gases emitted copper ducts get damaged.Can any one suggest a AC which can bear this effect or does not have

copper ducts?

Answer 1

I seriously doubt you have copper ducts.  I am in the States but even in the UK I have never heard of copper ductwork.  Copper is just too soft a metal.  If it is duct work you can use stainless steel for most chemicals or FRP (fiberglass reinforced plastic) for just about anything else.

My guess is that you are talking about refrigeration piping.  There is one company I know of here in the states that can make a stainless steel condenser coil.  The company is called Aaon and the make very custom high end commercial AC units.  They would be very very expensive.  It would be far easier the extend the vent that is emitting the gasses in the first place.
