DUO 12,000 BTU Portable Air Conditioner (MAP14AS1TWT-C)

Id give this a day or two of running see if it goes away.

I got this Midea Duo from Walmart refurbished last year for my bedroom and it's great. I live in the SW desert where it can hit 120° F. No problem, no leaks, no emptying (also no humidity to speak of where I live) Easy install (It *is* 75 lbs heavy, but on wheels), Wifi/Alexa compatible. It feels like a real workhorse that should last. The price was right too.

just got the Midea duo from Sam's about a week ago. running it in a 1940s house with no AC. it's a tad slow in actually cooling the space but it does eventually. You'll definitely feel it if you're in front of the vent.

I have this model, got it last year. Only really needed it for the summer months (June-early Sept) so haven't really been using it yet, but I just plugged it back in and started it to listen. I noticed that it *did* make a very slight high-pitched sound at start-up, but very quickly drowned out by the normal sound of it. I can just barely hear it too still, but I have to literally stick my head right next to the back of the unit to hear it. Doesn't seem nowhere near as pronounced as this video. I'd honestly return/exchange it for another unit if it doesn't seem to go away after like a day.

I ordered a refurb from Walmart a few weeks ago for $225 and it arrived like new https://www.walmart.com/ip/15245460485?sid=02142f3b-d972-4bae-af57-8db35407caeb&conditionGroupCode=2

Thanks for your response. The high pitched sound mine makes completely overshadows the fan sound on low setting and is still audible when the fan is on high even ~20' away and 2 days later. This does make it seem like my unit is defective compared to yours.

I have this unit and I came across this thread researching the same noise. It’s incredibly annoying and I am considering returning it to Costco but fear getting a replacement unit will have the same issue.
