A cool blast of discomforting brilliance, Air Conditioning examines the conditioning of our indoor and interior climates of work, domesticity, and consumption. It is not inward looking to the sealed boxes and bubbles of air-conditioned detachment, but focused on the complex exchanges and inequalities involved in sustaining comfortable places, cooled bodies and technologies by making other places, and other (often poor and racialised) lives, uncomfortable and unliveable. Hsu’s book hums, ventilating ideas in an insistent, vital tone to show how this ordinary object, submerged within walls and behind vents, has mattered so much to us.
