A wall with simple sheet type siding may be only 6 inches thick whereas a brick or stone wall can be much thicker. So wall air conditioner sleeves have ventilation louvers only in the back to avoid louvers being covered by the wall edges. This limits the amount of ventilation space available in turn limiting how powerful the unit can be. Wall air conditioners generally dont get much over 14000 BTU depending on the brand. So are they interchangeable? This question usually arises when someone needs a lot of cooling power in a room without suitable windows for a window unit.
Window air conditioners came to the market as a solution for people who couldnt afford or did not want central air conditioning. Because central air conditioning can be quite expensive and because many people live in small apartments central air is not for everyone. This led to the advent of window air conditioners. Window air conditioners have a hot coil and a chilled coil along with two fans. The fans blow air over these coils and they in turn suck away the heat and humidity from the room into the outside area providing clean cool air. The capacity of an air conditioner is measured in BTUs. So the size of the air conditioner plays a vital role in determining its cooling capacity.
Window air conditioners come in various sizes and it is important to choose the one that best fits the size of your room and needs of the user. The first thing to consider is to the rooms size. Using an climate control unit calculator or using the Energy Star chart for choosing a properly sized cooling appliance. For the average 150-250 square foot room youll need a climate control unit that has a capacity of 6000 BTUs. If you have rooms that flow into one another with archways or open doorways youll need to include the square footage of the adjoining room when calculating the capacity necessary to cool the area. Outside of square footage it is important to consider the climate of the room you wish to cool with an air conditioner.
