Although a desktop air conditioner is no match for a central air conditioner, it can still be useful in the warm summer days. There are some things that you need to consider before buying one.
Room size and effectiveness
The main disadvantage of the desktop air conditioner is that it can cool only a small area in a room.
Also, since the system relies on cooling the water, sometimes you may have to wait a few minutes before that air will get cooler. And this happens periodically.
Because the desktop air conditioner increases humidity, they shouldn’t be used near electronics, such as computers. Think where will it be placed and used before going to buy the unit. Most of the times it’s not worth spending money on them. They are quite a waste of money.
