'Portable air conditioners aren’t as mobile as their name suggests, and they’re also one of the loudest and least efficient ways to cool a room. But if you don’t have central air, and a window AC isn’t an option, a portable AC is the next best way to beat the heat—and if that’s the case for you, we recommend the Midea Duo MAP12S1TBL. It’s quieter, more powerful, and generally more pleasant to live with than nearly any of the other two dozen portable ACs we’ve tested (and the hundreds more we’ve researched) since 2016.
Most portable ACs are pretty similar, but the Midea Duo MAP12S1TBL delivers better cooling performance than other models while using less energy and making less noise. Rather than running only at max speed or nothing, the Midea’s inverter-powered compressor can operate at a continuously variable speed, so the unit has a lot more flexibility in how it reaches a desired temperature in a wide range of temperature and humidity conditions. In our tests, it was also remarkably effective at distributing the cool air, never leaving more than a 1-degree temperature difference across the room. Unlike the single-hose portables we typically recommend, the Duo has a unique “hose-in-hose” setup where the exhaust and intake are split into two separate conduits contained within a single larger tube, making it even more efficient. It’s one of the quietest portable ACs we’ve ever tested, too, with a volume that consistently measured below normal conversation levels. The Midea offers all of the standard smart-home capabilities, as well, including Amazon Alexa and Google Assistant support, and the smartphone app and the included remote offer even greater options for custom control.'
