Window & Wall Air Conditioning Systems
Window and wall air conditioning units are self-contained systems — everything is in one box, which is mounted either in a window frame or through an exterior wall. They require no outdoor unit, making them ideal for apartments, granny flats, server rooms and situations where a split system isn't practical.
Echo Air Conditioning supplies and installs quality window and wall units from leading brands. Our experienced team will ensure your unit is correctly sized, properly mounted and safely commissioned.
