Frequently Asked Questions (FAQ)
Is It Possible To Use A Portable Air Conditioner Without A Window?
Well, a portable air conditioner needs to release heat for effective functioning. A window with a seal is usually the best way for a portable AC to vent heat out. However, there are also other ways of attaching an exhaust tube to an AC or installing a small vent outside the AC that directs heat outside your space.
Why Does A Portable Air Conditioner Require A Window Seal?
A portable air conditioner can be transferred from one room to another, and they don’t require any installation. But they do require a venting area, like a window or wall. These air conditioner units extract hot air, and if you want your room to stay cool, you need to vent the warm air outside. For this purpose, you need a window, but there is a high chance that the hot air would come back and bring with it mosquitoes, dirt, and rain. Here, you need a window seal that will prevent the hot air from coming back.
Is It Simple To Install A Window Seal?
It is quite easy to install as a window seal on all windows and doors. Further, there is no requirement to call a professional as all window seals come with the necessary equipment and an installation guide, which will help you set up the window seal on your own.
