This is important because that way water drains out of your window rather than into your house. Condensation is a byproduct of air conditioning, and that water is going to come out somewhere, so that is why window-mounted air conditioners are designed so that the water will drain out of your house rather than into your room without you even thinking about it.
But if you have storm windows, this can be a problem, because the inside rim of the storm window, even when it is open all the way, is usually going to be higher than your interior windowsill, meaning your air conditioner is going to be very precariously balanced on the rim. Also, it is usually going to be far enough forward that you won’t get the proper tilt outside the window, and the water is going to drain into your house — that is, if your air conditioner doesn’t just fall out the window and kill somebody.
The best way to fix this is to get wood blocks and drill into your windowsill so you can secure the wood blocks, rest your air conditioner safely, and tilt it safely out the window without it falling. But again, if you are renting and it is August and you are moving out in like a month, this can seem excessive, even when it is necessary.
This is where Jonathan Franzen’s Freedom comes in. You put Freedom on the inside windowsill, and rest the interior base of the air conditioner on Freedom. Sometimes you can use other books too to interfere with the airflow around your air conditioner. This will let your air conditioner rest comfortably along the storm window and tilt properly outside the window and drain outside of your room rather than into it.
I did this one time. Don’t actually do this. It is a terrible idea and really dangerous.
I forgot the others.
