Window AC / September 14, 2018 / Aubrette Dumoulin
Another huge improvement in window air conditioners is in their appearance. Older models did not blend in very well with their surroundings. They were usually some shade of brown and looked like there was a box in your window. Window air conditioners today are much less obtrusive and look less like boxes. Corners are rounded and colors are much lighter. This gives them a much sleeker look. As with most things once they have been around for awhile cost become more reasonable and less of an obstacle. A window air conditioner can be purchase for less than two hundred dollars and often not much more than one hundred dollars. Of course this is for smaller units. Costs go up as the cooling capacity of the unit increases.
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.
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.
