The condenser lives in the window
System installed where outdoor space is limited or unavailable — a solution for many
apartment buildings in NYC. The Fujitsu 15RLQ condenser is securely attached to the
window frame and boxed from inside, yet the exposed coil allows free air circulation from
outside.
No duct, and no hole drilled through the outside walls — which means a clean installation and, usually, a board that says yes.
