FAQ's

Can I use a portable air conditioner in a room without a hose?

Yes, but only if it is an evaporative cooler which doesn’t need a compressor and refrigerant to run. Standard portable air conditioners which use refrigerant and compressors need to vent out the hot air ideally outside the room that they are operating in. The only way they can be used without the exhaust hose is when they are used in fan or dehumidifier modes.

Where do you vent a portable air conditioner?

Portable air conditioners can be vented through a window, wall, ceiling or door. Ideally, you want to vent them outside the room that they are operating in as they pull the hot air in, circulate it through coils to cool it down and exhaust excess warm air through the hose. Letting the portable air conditioner vent out in the same room that it operates in would result in making the space even hotter.

How many BTUs do I need for air conditioner?

The amount of cooling power air conditioner needs which is represented in BTUs (British thermal unit) will depend on many factors like temperature outside, insulation of the building, number of windows and doors in the room as well as changeable factors like number of people in the room, any devices and appliecnes in the room that generate the heat like computers, monitors, fridges or TVs. For the average BTU needed to cool your room see table below which is based on standard room with 2.5m ceiling, two windows and one door.
