Our Verdict
The Midea Duo MAP12S1TBL is great for large rooms. It'll perform quite well in bigger spaces like living rooms, though it's worth noting that a window unit with comparable capacity will cool an equivalently sized space even faster. On the upside, it makes very little noise while running, so it won't be much of a nuisance wherever you set it up. It does incur moderate energy consumption while cooling, but it's highly efficient when maintaining your desired setpoint.
Low overall operating noise.
Cooling capacity is sufficient for all but massive open-concept rooms.
Keeps rooms cool and dry instead of cold and clammy.
Higher energy consumption when cooling a room compared to an equivalent window unit.
Occasionally produces a distracting chattering noise.
The Midea Duo MAP12S1TBL is a very good choice for use in smaller rooms. Its inverter compressor gives it the flexibility to operate efficiently in undersized spaces without causing substantial swings in perceived humidity. It's also a good option for light sleepers, as it runs very quietly during normal operation. Unfortunately, this is a very bulky unit, so it can be hard to fit into smaller bedrooms where space is at a premium.
Low overall operating noise.
Good energy efficiency when maintaining desired temperature.
Keeps rooms cool and dry instead of cold and clammy.
Bulky design makes it challenging to fit in tighter rooms.
Occasionally produces a distracting chattering noise.
The Midea Duo MAP12S1TBL's maximum cooling capacity is impressive and sufficient for a wide range of room sizes. It has the necessary output to cool large primary bedrooms, average-sized living rooms, and a variety of other medium-sized spaces. That said, you can't expect this unit to operate effectively in open-concept living spaces or entire apartments.
Cooling capacity is sufficient for all but massive open-concept rooms.
The Midea Duo MAP12S1TBL is an energy-efficient A/C unit. It isn't as efficient as a window-style unit with equivalent cooling capacity for cooling a room, but its inverter compressor offers efficiency benefits for maintaining a room's temperature. It can modulate down to a low speed instead of cycling on and off to keep the ambient temperature at your desired setpoint.
Good energy efficiency when maintaining desired temperature.
Higher energy consumption when cooling a room compared to an equivalent window unit.
The Midea Duo MAP12S1TBL is exceptionally flexible and can be used in a variety of room sizes. Its inverter compressor can simply operate at a lower band in smaller rooms instead of going through an energy-intensive cycling process. It minimizes temperature and perceived humidity fluctuations and ensures your environment feels cool and comfortably dry rather than cold and clammy.
Keeps rooms cool and dry instead of cold and clammy.
The Midea Duo MAP12S1TBL is amazingly quiet overall. Even at its highest setting, its operating noise is low enough to be masked by most common household noise sources, such as nearby conversation or a TV at a normal volume. That said, like most A/C units equipped with an inverter compressor, it can occasionally produce a chattering noise, which can be distracting if you have it set up nearby.
Low overall operating noise.
Occasionally produces a distracting chattering noise.
The Midea Duo MAP12S1TBL is a bulky appliance. The unit itself takes up about as much space as a large end table, and while its two-into-one hose design gives it a slightly smaller footprint than more conventional dual-hose units, it still takes up quite a bit of room.
Bulky design makes it challenging to fit in tighter rooms.

Differences Between Sizes And Variants
The Midea Duo MAP12S1TBL is only available in one color variant: 'Black.' For those interested, here's the product label.
If you're looking for a similar unit with higher capacity, there's also the Midea Duo MAP14AS1TWT-C, specific to Costco stores and available only in 'White'. It boasts a higher advertised capacity of 12,000 BTU. As a result, we expect it to perform similarly to the Whynter NEX ARC-1230WN, which is mechanically related to the MAP12S1TBL and uses a higher-capacity 12,000-BTU compressor.

Popular Air Conditioner Comparisons
The Midea Duo MAP12S1TBL is a high-end portable A/C. It's a bit of a standout among portable A/Cs, going toe-to-toe with the Whynter NEX ARC-1230WN, another segment leader in the high-end portable A/C niche. The Midea offers enough cooling capacity to handle all but the largest spaces, and it has good overall energy efficiency thanks to its dual-hose design and inverter compressor. It handily outperforms the Hisense HAP0824TWD, another dual-hose inverter unit, in most key ways: the Midea provides slightly greater cooling capacity, lower energy consumption while maintaining your desired setpoint, and quieter operation.

The Whynter NEX ARC-1230WN and Midea Duo MAP12S1TBL are mechanically similar units, sharing the same physical and in-app control interface. That said, the Whynter packs a more powerful inverter compressor, allowing it to cool an equivalently sized space a little faster. That said, the Midea is a little more efficient, particularly in undersized spaces.
The Midea Duo MAP12S1TBL is a better overall A/C than the Hisense HAP0824TWD. The Midea has a higher overall cooling capacity, enabling it to cool rooms a little faster while incurring lower energy costs during the cooling and maintenance phases. Not only that, but it also runs noticeably more quietly. That said, the Hisense is a little more compact and significantly lighter, making it a little easier to transport.
The Midea Duo MAP12S1TBL performs better overall than the Hisense AP1022HW1GD. The Midea unit's inverter compressor allows it to maintain more consistent humidity and temperature levels while minimizing energy consumption once it has reached your desired setpoint. That said, the Hisense is noticeably smaller and easier to stow away when not in use.
The Midea Duo MAP12S1TBL is simply better overall than the LG DUAL Inverter LP1419IVSM. The Midea's dual-hose design gives it a major advantage in efficiency over the LG, allowing it to cool a comparably sized room much faster while consuming less energy. Its two-in-one hose design also means that it's only marginally bulkier than the single-hose LG.
Test Results
The Midea Duo MAP12S1TBL provides impressive cooling capacity. It can cool the vast majority of living rooms or bigger playrooms, but it can't keep up with a window unit with comparable capacity if you're looking for something that can cool a larger open-concept apartment by itself.
Note: Several user reports from online retailers indicate a number of units that suffer from poor overall cooling performance. This wasn't the case with our own test unit, but if you do own or have owned this unit and have experienced any performance issues, reach out to us in the comments.
This A/C unit has decent cooling efficiency. It doesn't operate as efficiently as a high-capacity window unit like the Midea MAW12HV1CWT in this regard, as it'll take noticeably longer to cool an equivalently sized space, all the while having higher upfront energy demands. Still, it's efficient for a portable unit and much better in this regard than a single-hose model like the LG DUAL Inverter LP1419IVSM, which lacks a proper intake to cool the compressor as it runs.
The Midea Duo MAP12S1TBL's energy efficiency while maintaining the setpoint is good. As an A/C unit with an inverter compressor, it doesn't have to cycle its compressor on and off to maintain a set temperature.
That said, this unit can briefly modulate its compressor to a higher speed in this maintenance phase, resulting in brief spikes in its energy consumption. Thankfully, these spikes are unlikely to have much effect on your energy bill in the warmer months.
This A/C does a fantastic job of maintaining a stable temperature level once the setpoint is reached. There's little need for the unit's inverter compressor to modulate during the maintenance phase, ensuring temperatures remain at the level you desire rather than cycling around that point.
The Midea Duo MAP12S1TBL is fantastic at maintaining ambient humidity at your desired temperature. The compressor modulations are brief and small enough that they don't noticeably affect a room's perceived humidity. As a result, the room that the unit is cooling will feel comfortably and consistently dry.
High-pitched operating noise from the compressor is a common complaint for inverter A/C units. This chattering noise can be heard faintly in the 'Inside Noise @ Low' test video. This noise is completely normal once the unit enters a cooling cycle and isn't a cause for concern.
This is a pretty feature-dense air conditioner. You can operate the unit using its control panel, the remote control, or the Midea Air app, which also supports Amazon Alexa and Google Assistant devices for making voice commands.
