Important considerations when choosing a portable a/c

You might be looking buying or even at a rental portable air conditioner. Here are some important points to consider when choosing:

Power cord

All manufacturers recommend against using portable ac units with extension cords. Portable air conditioners consume a lot of power and an extension cord, with or without additional devices plugged in, might not provide sufficient power. Also, check the fine print, as using a portable unit with an extension can void your warranty. The biggest danger is an electrical short that is a potential fire hazard.

Window kit

When you need to run an exhaust for your portable a/c, there can be a gap in the window. Use a window kit to cover the gap in the windows. However, not all units require an exhaust outlet. Units from are self-contained, enabling quick and easy set-up, installation and breakdown at all events.


Air conditioners have a variety of modes. You can use them for cooling or as a dehumidifier. A portable dehumidifier will increase comfort levels without using too much electricity. Cooling, on the other hand, uses more power and cools the room while removing humidity. There are also other modes that use a combination of cooling and humidity removal.


Since portable air conditioners are mostly self-contained, they can be rather noisy. The loudest point is when the unit is working flat-out. Consider using a portable a/c only when you do not require quiet cooling.
