Portable cooling in Egypt: ACs and air coolers

Compare the main types

Ask yourself one question before any specification: can you install a split instead of a portable? A split unit has its compressor mounted outside on a wall or balcony, so it cools better and runs quieter for the same space, and for most people who can install one the split is the smarter choice. A portable AC proves itself precisely when that installation is not possible: a rented flat where outdoor work is not allowed, a temporary living situation, or a single room you want to cool without any building work. The trade-off is that the whole system, compressor included, sits in the room with you, so it is noticeably louder, and that is the regret most often mentioned in reviews of this category. If that is your situation, size the BTU rating to your room: 8,000 to 10,000 BTU for a room up to 12 square metres, 10,000 to 12,000 for an ordinary bedroom of 12 to 18 metres, and 12,000 to 14,000 for a large room or small living area, while above 25 metres a portable starts losing effectiveness. These are approximate starting figures, not an engineering calculation: go higher for direct sun, a high ceiling, poor insulation, or more people in the room, and when you are between two numbers pick the higher one, because an undersized unit runs flat out without ever reaching the temperature you want. The exhaust hose is not optional: the unit draws in room air, cools part of it, and expels the rest along with the heat it has collected through the hose, so without a proper outlet to the outside (a window kit, a vent cover, or a small wall opening) it feeds its own heat back into the room and cools almost nothing while running at full power. A single-hose model draws its cooling air from the room itself, creating a slight negative pressure that pulls warm air in from outside to make up the difference, while a dual-hose model takes that air directly from outside, making it more efficient but larger and more expensive. And every real AC collects condensate: most models store it in a tank you empty by hand, while some have a continuous drain outlet you can connect to a hose running to a floor drain or an outside drainage point, so check your model's manual because that specification is not always stated in the listing. Finally, watch out for the most common confusion in this category: an evaporative air cooler is not an AC. It blows air across a wet pad and adds humidity to the room while it runs, which helps reasonably in dry heat but can make the air feel heavier rather than cooler in humid coastal cities.
