Midea Duo MAP14S1TBL review

The Midea Duo is the inverter portable that most closely matches the Whynter ARC-1230WN on paper. Midea lists 12,000 BTU on the DOE scale and a room size of up to 550 sq ft, and says its variable speed inverter gives over 40% energy savings compared to the US federal standard. Like the Whynter, it uses a hose-in-hose design: one window connection both pulls in outside air and expels hot air, which avoids the negative pressure of single-hose units. Midea rates it as low as 42 dBA. Control runs through the SmartHome app, Apple Watch and voice assistant devices, and the unit cools, dehumidifies and ventilates. The window kit fits a variety of window types and the unit rolls on four wheels. The drawbacks are weight and warranty: at 74.96 lbs it is heavy to carry upstairs, and Midea lists a one-year warranty. Midea's US store lists it at $659.99, the same as the Whynter ARC-1230WN, but showed it as Notify Me rather than in stock when we checked.
