Many DIY enthusiasts opt for the window AC system because of one major reason: it is easy to install. But that does not mean that all these people have mastered the art of installing this type of AC system correctly. In fact, a majority of the window ACs installed by inexperienced DIYers do not operate at maximum efficiency. In that regard, be sure to avoid the following rookie mistakes when you are fitting your first window AC unit.
Incorrect sizing of the unit
For any air AC to perform optimally, its size should be in accordance with the size of the room where the unit is being installed. However, there's a common misconception that the larger the size of an AC unit, the greater the performance level. The truth is that an oversized unit will overload quickly, thus causing the unit to frequently turn on and off before reaching the cycle. An undersized AC, on the other hand, would have to run harder than it should to cool the room. This would, in turn, increase your monthly energy bills. Make sure to take measurements of your windows, ceiling, walls, and floors to help you choose the proper-sized unit for a room.
Wrong placement of the unit
Placing the AC suitably is also very important because it can affect its energy performance. Be sure to understand how the sun moves so you can place your AC unit on windows that are not admit direct sunlight. Install your window unit according to window orientation and shading will ensure that the unit does not have to run harder to cool your home. Locating your unit at a shady spot that receives less direct sunlight boosts the cooling efficiency of your unit immensely. The spot should also have proper ventilation so that hot air can find its way out without any obstruction.
A lot of homeowners don't bother sealing the gaps created in their windows once the AC is installed. This could prove to be a big blunder because the open areas will allow the hot air from outside to enter your home and the cool air indoors to leak outside. One smart move would be to fill up the gaps around your window unit with insulating foam. This will ensure the air leaks are sealed up, thereby reducing energy waste within the AC system.
If you do not have insulating foam, you can alternatively use pasteboard. You can cover the pasteboard in aluminium foil and secure it using duct tape. Aside from filling the gaps, the aluminium will also help dissipate the heat.
