I have a 90 day warranty so I plan on beating it to hell soon.
Currently $250 Walmart refurbished.

Duo 12,000 dual-hose AC to a wall vent in an apartment
I'm trying to figure out if it's realistically possible to hook up a Midea Duo 12,000 BTU dual-hose portable AC to an existing wall vent in an apartment (instead of using the window kit as my window is not sliding window).
The wall vent is a standard circular outlet.
Before I start experimenting with adapters, reducers, or DIY seals, I wanted to check:
• Has anyone actually done this successfully?
• What adapter or setup worked for you?
• Any airflow or back-pressure issues I should watch out for?
• Did it affect cooling performance or noise levels?
Photos, part links, or even "don't do it, here's why" stories would be super helpful. Trying to keep things clean, safe, and landlord-friendly.
Thanks in advance to anyone who's tried this or has ideas.
