Where can one buy used Airconditioner in Kochi?

Are there any good used AC or factory seconds shops selling AC here? Those instagram marketted places only stock some select appliances but never AC. Looking for some place where they service these as well as sales. Tried OLX , felt it's too much effort to check and move it to my location. I need a 1 ton and a 1.5 ton AC. Any inputs welcome. Want to exhaust any used possibilities before going for new.
