Wall mounted air conditioners are the most common units used in a bedroom setting. The two main advantages are that wall units are the cheapest to install and they are also easy to retrofit in bedrooms without the need for redecoration. They are long, thin and placed at a high level on the wall. Like all models designed for bedrooms, they are exceptionally quiet which means that they’ll never stop you from having a good night sleep.
A single wall unit is almost always powerful enough for a bedroom, as you can see from the photos. The units are all remote controlled so you don’t need to move from the sofa or your bed to alter the settings!
