Those Meaco units are great! I bought the 10000BTU unit to cool the house as we have a baby, the baby doesn't like it for some reason and prefers to sleep without it. My win though as our bedroom was a cool 19°c when downstairs was 28°c. I think A/C will be pretty standard in the UK in 5/10 years time.
I have one, got it from costco its on the louder side but in terms of everything else cant fault it cools my room down nicely. Did end up buying a longer exhaust hose as the one provided is on the short side.
Meaco have an eBay store where they sell "refurbished" units, I bought a 10,000 BTU model for £160 a few months ago, with 2 year warranty. As far as I could see it was brand new.
Ive got a Meaco 10kBTU and love it.
Nabbed one from them on a Black Friday deal a couple of years ago and it's absolutely transformed my summer sleep quality. Having solar panels on the house also minimises the energy costs beyond a quick burst in the evening to cool the room before going to bed.
If that's a meaco you can 3d print an adapter and add a second hose to make it more effective https://vm.tiktok.com/ZNdH85QtD/
