Customer Reviews For The Honeywell Contempo Series Portable Air Conditioner, 12,000 BTU

Portable ACs use either a single hose or dual hose design. In cooling mode, single hose PACs remove hot air from the room, and then expel the hot air out the one hose. In cooling mode, dual hose PACs bring in air from outside through one hose, and expels warm air outside through the second hose. In both cases cold air in cooling mode flows through the unit's vents into the room.

Casement windows are quite unique in design and functionality so PACs do not have window kits that can completely cover the gap for these types of specialty windows.

The screen may not interfere with installation, but for better releasing of hot air out the window, it is better to remove the screen.

A BTU (British Thermal Unit) is a standard unit of energy that measures the amount of heat per hour an air conditioner removes from a room. The larger the room, the higher the BTU requirement. Below, are some general guidelines. However other factors – such as the number of open doorways, a south-facing window with continuous sunlight, or a room with high occupancy – can require a unit with a higher BTU rating than the average guidelines.
