Energy efficient air conditioner unit
The main advantage of a portable air conditioner is that it can be moved around the room with great ease. There are a few things that you need to consider before buying the unit.
The size of air conditioners is measure in BTUs.
Placing the unit
When the air conditioner is working it transforms hot air in cold air, and it exhausts heat. Usually this heat is eliminated through a hose placed on a window. This is way it’s quite important to place the unit near a window. Otherwise the heat will be eliminated back in the room.
No matter the type of air conditioning unit, it will still make some noise. If this disturbs you, then buy an unit that is as silent as possible.
Read the EER rating and also the Energy Star rating. A higher EER rating means higher efficiency.
