The window air conditioners are required to cool small rooms. They are small units which can be installed in the window frames to provide relief to the scorching heat without necessarily installing them.
The miniature versions of window AC are highly powerful and compact.
Small window air conditioners are ideal to be used in apartments, dorm rooms or small offices where space is not a lot. They cool a specific area and this conserves energy unlike the whole-home systems.
The small ones tend to cool rooms that are not more than 150 square feet and therefore they are best suited in bedrooms or home offices.
Choosing a small window AC, you are to consider its BTU rating, energy efficiency, noise level and size. BTU (British Thermal Unit) capacity is what determines the cooling power and Energy Star certification lowers the operating costs. The noise can be a problem to the quality of sleep and thus find less noisy models.
Ensure that you take the measurement of your window opening to fit.
