Window AC / September 6, 2018 / Marphisa Babin.
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.
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.
When purchasing a window air conditioner it is very important to purchase one with the proper cooling capacity. An air conditioner that is not properly sized will not work as efficiently as one that is sized properly. This is one of the most common mistakes made when selecting air conditioners. Use an air conditioner size calculator to select the proper sized unit for the room you want to cool. Undersized air conditioners will run continuously and not cool the space adequately and an oversized unit will cycle on and off too often. This increases equipment wear and can actually cause fuses to fail.
When a small window unit for a large room is not enough a large unit for a small place is waste of money. So you should buy a window air conditioner appropriately based on your room space. For a space up to 350 square feet you would require 8000 BTUs. The number of BTUs grows proportionately according to your space. Window air conditioners have high-energy efficient ratios noise-free and when fitted properly cool an entire space very quickly. There are lots of types of window air conditioners from different companies available at different prices. Companies like Haier Kelon and Carrier have products starting from price ranges as low as $50-$150. They come with quiet operation function timer dehumidification air filters and much more.
