Window AC / September 13, 2018 / Marphisa Babin.
Window units of today are very quiet and their efficiency has improved a lot also. In fact these units are so quiet that you can hardly even hear them operating. Window air conditioners have the same components as a central air conditioner but they are all installed in small cabinet. The biggest and most important difference is that they dont have to cooling capacity of central units. But they also dont cost as much to operate either. If you only want to cool one or two rooms then window air conditioners are a perfect choice. However if you want to cool your entire home a central air conditioner is the best alternative.
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.
If the room is shaded then you can decrease the BTU rating you calculated with the climate control unit calculator by 10 percent however if you wish to cool a kitchen youll need to raise the rating by 4000 BTUs. When the room you are cooling is used by two or more people add six hundred BTUs per person to the rating necessary to cool the room. Before you buy the first air conditioner that fits the BTU rating necessary to cool your room make sure you have a window that will be suitable for the unit. Measure windows in the room (make sure not to block fire escapes) and make sure to buy a window air conditioner that will fit into the opening.
So what you should do? The best thing to do is to check out the sound levels on your window unit before you make your purchase. All air conditioners come with labels specifying the decibels generated by the unit. A high number means a loud machine. For example a unit with a rating of 50 Decibels is 10 times louder than one rated 40 Decibels. The smartest thing to do is to go to a big box store like Target or Walmart and listen to an air conditioner before you buy it. Even if you are looking at a different brand it is important to get a sense of how loud the Decibel ratings are for you. You can do this best by listening to different ac units running.
