Wall-thru air con replacement

Categories: A/C

I need to replace an existing wall-through air conditioner, and I want to do it myself. All the installation instructions tell me to caulk on the inside and outside after it’s all installed, for weather proofing. This sounds fine, but I’m on the 5th floor of a 12 storey building – I cannot get to the outside.

Anyone have any ingenious ideas to better weather proof when I cannot reach the outside of the air conditioning unit?
