As the demand for cold runs proportionate with the socio-ecological realities, like the rising mercury level impacting the balance between urbanized lifestyle on one hand and ecological preservation on the other hand, the choice of the right air conditioning system underpins the challenges related to air conditioning system that’s now an integral part of modern life. Nowhere this is more evident than in the United States where three-quarters of the household population use an air conditioner. From 1993 until 2009, according to the US Energy Department citing a figure from a survey, the percentage of American households that use air conditioners significantly rose from 68% to 87%, a staggering figure that reveals the extent of widespread use of AC in the country. Now just imagine that figure growing exponentially over the years. Of course, you can safely bet on a much higher percentage today. The agency, likewise, determines the type of air conditioning system that is prevalently used. It was concluded that aside from centralized air conditioning unit, window air conditioner comes out as the system of choice. Now, take note that the type of air conditioning system used, as the DOE states, varies in different region in the United States. This is understandable when taken in the context of looking at climate differences, household income differences, and variations in housing types among these regions. Centralized air conditioning systems, according to the Energy Department, for instance is more commonly used in the Midwest as well as in the Southern and Western parts of the country. The use of room air conditioners, however, is more prevalent in Northeastern region. Nonetheless, it must be pointed out that between centralized air conditioning unit and window air conditioner, the latter is more popular. Thus, this article examines what the window air conditioner is, what it can deliver, and what are the best brands that you can use.
