What to Consider When Choosing an Air-Conditioner Unit?
The most important decision when it comes to choosing a window air conditioner is the size. A too small model cannot adequately cool and the one that is too big will cool the area before it removed the sufficient humidity, and then eventually leave the room clammy cold.
Window units air conditioners range from 4,000 to 34.500 BTUs in power. With these range it is easier to find one that closely matched your needs. But it is not easy to determine what size to buy. It still depends on the climate where you are living, the area to be cooded, the direction the windows are facing and the number and size of windows.
When it comes to choosing the best size, do not rely on guesses or instinct. It is better to by a bit less than the optimum power than more becasue calculations are based on how much is need on hottest seasons.
Once you have chosen the perfect size you need, the next thing to chec is the EER or the energy efficiency ratio. This will tell you how efficient the air conditioner convert electricity to cooling power. And it is teh key to knowing how much it will cost to run.
