Side panels fill the gaps on the sides. These are also very thin so most of the sleeve is uncovered and outside. This allows for placement of ventilation louvers on the sides and top allowing free movement of air. This is the primary difference between the two types. The wide availability of louver space allows the unit to move a lot of air and this means window units can be quite powerful up to 3 tons or 36000 BTU. So window A/Cs can be effective for very large rooms. In contrast a wall air conditioner sleeve is designed for a hole through the wall. Walls vary substantially in thickness.
Depending on the size and level of insulation of your home one window air conditioner is typically enough to cool one or two rooms but larger units may even be able to cool an entire 2-3 bedroom apartment. Using multiple cooling units in a home will allow each person in the family to keep their room at the temperature they desire. Installing a cooling unit will take anywhere from ten to forty minutes. Choosing the Right Air Conditioner
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.
