Window AC units are a powerful and efficient air conditioning solution. This is the most common type of free-standing air conditioner, and these usually come with the hardware needed to fit the unit into most different types and sizes of window. They typically require some sort of external support, such as a simple shelf. What many people don't realize is that you can often install a window air conditioner yourself. However, there are many options for professional installation as well.
Window units are a convenient choice because they take up less room space than traditional room air conditioners while being relatively easy to install and remove. They also tend to have more cooling and heating power than self-contained, portable machines.
