My two cents: I have a 9,000 BTU Alliance installed in December 2025, and 6 weeks later got a 24,000 BTU Alliance. The Midea units were about R2k more expensive at the time, so I didn't think it was worth the extra cost.
However, my sister—who lives 1 km down the road—got a 24,000 BTU and two 12,000 BTU Mideas installed from the same installer i've used and wow, they are much quieter than the Alliance units.
Another factor to consider is the app: the Midea app is a lot nicer and provides far more stats if you're into that sort of thing.
