1. An indoor unit comprising:
a housing comprising a plurality of panels joined together, the plurality of panels comprising:
a wall-side panel having an exit-point thereon;
a room-side panel arranged substantially parallel to the wall-side panel;
a lower panel arranged substantially parallel to the upper panel and substantially perpendicular to each of the wall-side and room-side panels;
a first side panel arranged substantially perpendicular to each of the wall-side, room-side, upper, and lower panels; and
a second side panel arranged substantially parallel to the first side panel and substantially perpendicular to each of the wall-side, room-side, upper, and lower panels,
wherein the housing has:
a height of less than 11 inches measured between the upper and lower panels;
a depth measured between the wall-side and room-side panels; and
a width measured between the first and second side panels;
a refrigerant line running through the exit-port on the wall-side panel, the refrigerant line having a portion that is internal to the housing; and
a plurality of components enclosed within the housing, the plurality of components comprising:
a heat-exchanger connected to the portion of the refrigerant line, wherein the portion of the refrigerant line is external to the heat exchanger, runs substantially within a height-depth plane perpendicular to the width of the housing, and traverses less than 25% of the width of the housing;
a fan arranged between the heat exchanger and the lower panel; and
a control unit operatively coupled to the heat exchanger and the fan,
wherein the indoor unit is configured to exchange at least 8000 BTUs/hour with a room and wherein the indoor unit produces a noise of 48 dBA or less.
