Often acquired impulsively on summer days when one can no longer tolerate the heat, window AC units almost invariably clash with their surroundings, in terms of both material and design. DIY installations involving brackets, loose bricks, and chains add to the visual medley. All of this is compounded when the exposed coil of the street-level AC also becomes a drawing board. Technically close to etchings, these inscriptions range from tags, to initials, to free-style drawings. The rigid frame imposed by the appliance often gives these scrawls the appearance of canvases or signed documents. While their authors remain ironically anonymous, these visual marks nevertheless turn otherwise prosaic items into entirely unique surfaces. I see these AC coils and their immediate surroundings as complex intersections where architecture and design interact with make-do lives and street art and I am continuously drawn to their poetry.
