Window AC / September 23, 2018 / DixieLemieux
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.
To help make that decision more clear I will explore some of the positives and negatives of the two major options. Ductless split type units are also becoming more of an option. I will do another article on that option. To include that in this article would just be more confusing. So for now we will just look at window air conditioners and central air conditioning. Central air conditioning is the best way to go if you already have a central hot air heating system already installed in your house or building. The advantage that you have is that you already have the air handler or blower part already installed.
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.
