Installing window A/C over roof?

Question

I want to install a regular window A/C. These A/Cs usually release water drops when they're on.

Unfortunately, directly under my window there's small aluminum roof from an external balcony built in the 2nd floor. So if it starts leaking, the drops will fall on the roof and bother the neighbor.

I can't install it unless I find a way to avoid the drops from falling on the roof.

Is there any way I can do that?

Thanks.

Answer 1

You'll have to install a drip pan under it with a drain line running off to the side.  All air conditioning units, window or central, extract moisture from inside the house and drain it to the outside.  Some of this moisture is purposely picked up by window unit fans and is sprayed on the coils to aid cooling of the refrigerant.  Therefore your drip pan will have to be somewhat larger than the unit, i.e. extend out the back a few inches.

Answer 2

There should be some kind of drain tube on it. Just get some tubing and extend it.

Answer 3

The one I just bought has a plug on the back end that can be removed and a fitting installed. You can then install some tubing and run the drain away from the overhang. BUT it sounds like you are on the third floor so you might have a bit of trouble running that line.

Good Luck
