The Midea MAW12HV1CWT is a window A/C with an inverter compressor, designed for medium- to large-sized rooms. It's effectively a more conventionally designed version of the Midea U-Shaped MAW12V1QWT: the two units share similar internals, and both have an advertised coverage of 550 ft² (51 m²). Like that model, it can be operated remotely via the smartphone companion app and integrates with Amazon Alexa or Google Assistant devices, so you can make settings adjustments via voice controls. However, the MAW12HV1CWT does offer the added bonus of a heating mode.
Our Verdict
The Midea MAW12HV1CWT is an excellent option for large rooms. Its cooling capacity is high enough to quickly cool large living rooms or playrooms, and its inverter compressor helps it consume less energy than non-inverter alternatives while maintaining your desired temperature. It's also pretty quiet overall and won't be a distraction if you place it next to your television or near your dining room.
Runs quietly, regardless of setting.
Highly energy efficient operation.
Cooling performance is sufficient for bigger rooms.
Minor fluctuations in perceived humidity when maintaining temperature.
The Midea MAW12HV1CWT is a very good option for cooling bedrooms or other small rooms. It runs quietly and won't wake you up in the middle of the night. Its inverter compressor can run at a lower speed pretty consistently, so you won't experience major swings in your desired temperature or humidity, even in small areas. However, it is on the bulkier and heavier side for a window unit, making it a bit of a bear to haul into place or stow away in cooler months.
Runs quietly, regardless of setting.
Highly energy efficient operation.
Inverter compressor minimizes swings in temperature.
Minor fluctuations in perceived humidity when maintaining temperature.
Relatively bulky and heavy, making installation difficult.
The Midea MAW12HV1CWT's cooling capacity is excellent. It's sufficient for it to cool larger living spaces and open-concept areas within a relatively short span of time.
Cooling performance is sufficient for bigger rooms.
The Midea MAW12HV1CWT is amazingly efficient and won't have too much impact on your energy bill in warmer months. Its inverter compressor is quite efficient at cooling a space and maintaining that temperature, as it won't have to constantly cycle off and ramp back up once that point is reached.
Highly energy efficient operation.
The Midea MAW12HV1CWT is flexible enough for use in a variety of room sizes and does a great job of maintaining ambient conditions. Thanks to its inverter compressor, it can run at a slower speed to prevent overcooling in undersized areas, so your room should feel cool and dry rather than cold and clammy. That said, its compressor does modulate slightly up and down once it's reached your desired temperature; this can have small impacts on a room's humidity once it's reached your setpoint, but in real-world terms, these swings aren't too noticeable.
Inverter compressor minimizes swings in temperature.
Minor fluctuations in perceived humidity when maintaining temperature.
The Midea MAW12HV1CWT is amazingly quiet. At lower settings, it's barely noticeable. Even at higher settings, it emits white noise that will be easily masked by most other sources of ambient noise, whether that be nearby conversation or a TV playing at a normal volume.
Runs quietly, regardless of setting.
The Midea MAW12HV1CWT is a somewhat bulky appliance. It's wide, tall, and fairly deep, which can make fitting it in certain window styles something of a challenge. Beyond that, it'll also take up quite a bit of space in your closet when stowing it away in cooler months, and its heavy weight means you're better off calling a friend for help when it's time to set it up.

Popular Air Conditioner Comparisons
The Midea MAW12HV1CWT is a high-end window A/C designed for medium- to large-sized rooms. Its closest and most obvious competitor is Midea's own Midea U-Shaped MAW12V1QWT. Both models perform quite similarly and are standouts in their class, with very high cooling capacity, impressive energy efficiency, and impressively quiet operation. The MAW12HV1CWT's more conventional design has its own set of strengths and weaknesses: you can't open the window when it's set in place, but the first-time installation takes less effort. While this is an impressively efficient A/C overall, it isn't quite the market leader on that front: the Friedrich Chill Premier Inverter CCV08A10A incurs an even lower upfront energy cost, admittedly with a lower overall cooling capacity. Still, the latter is also a good option if you have a smaller room that needs cooling but don't want to sacrifice features or efficiency.

The Midea MAW12HV1CWT is better than the LG LW6023IVSM. The Midea's greater cooling capacity gives it an edge when cooling larger spaces, and it's more efficient while running as well. Despite its greater overall cooling capacity, it's a little smaller and lighter than the LG, though it's still likely to be too much of a handful for one person to comfortably set up. With that said, it's worth noting that the LG is noticeably quieter at higher fan speeds and does a better job of maintaining your desired humidity and temperature levels.
Unsurprisingly, the Midea MAW12HV1CWT and Midea U-Shaped MAW12V1QWT deliver nearly identical performance, both inverter ACs with an advertised output of 12,000 BTU. The main difference lies in their designs. The MAW12V1QWT's unconventional U-shaped design makes for a more demanding installation process since you'll need to install additional anti-tip brackets, but it also allows you to open the window when it's in place. Beyond that, the MAW12HV1CWT has a heating mode that the MAW12V1QWT lacks. It's worth noting that only the U-Shaped MAW12V1QWT is affected by a recall due to mold buildup.
The Midea MAW12HV1CWT is a higher-performing window A/C than the Midea MAW08V1YWT-S. The two units share the same exterior design, but the MAW12HV1CWT uses a more powerful compressor that yields a higher cooling capacity, allowing it to cool an equivalently sized space roughly 50% faster. That being said, the MAW08V1YWT-S does a noticeably better job of maintaining your desired temperature and humidity level.
Test Results
This air conditioner offers excellent cooling capacity. It can cool larger, open-concept living spaces within a relatively short time. Thanks to its inverter compressor, it's also a good choice for smaller bedrooms, as it can modulate its output to match the room's load demands.
The Midea MAW12HV1CWT's efficiency while cooling is great. Its upfront energy cost is moderately high, but the unit cools very quickly, so it won't have to run its compressor for very long.
This unit delivers amazing efficiency while maintaining your desired temperature. Its inverter compressor can run at a lower speed rather than cycling between binary on and off states. It's worth noting that its compressor modulates slightly during this maintenance phase rather than remaining at a constant speed, which can have knock-on effects on maintaining the set temperature and the perceived ambient humidity levels.
This A/C unit does a very good job of maintaining a stable temperature once the setpoint is reached. Modulations from its inverter compressor are minor, which helps keep temperature fluctuations in check. Still, if you want an A/C that does better in this respect, check out the Midea MAW08V1YWT-S.
The Midea MAW12HV1CWT does a good job of maintaining ambient humidity levels at your desired temperature. The small modulations observed in the Efficiency When Maintaining Temperature test result in minor fluctuations in the ambient humidity of the room you're trying to cool, but they won't be especially noticeable, even in very humid environments.
High-pitched operating noise from the compressor is a common complaint for inverter A/C units. While this noise can be disruptive if you're standing near the outside portion of the unit, it's completely normal once the unit enters a cooling cycle and isn't a cause for concern. All the same, if you want an even quieter air conditioner, the LG LW6023IVSM is a good option.
We observed the same noise during testing, but this didn't factor into the score for this section of the review, as the score is based only on dBA readings taken from the primary recorded video for this test. Also, this sound would likely only be heard by those standing outside the window.
This is a smart air conditioner with a feature set similar to that of the Midea U-Shaped MAW12V1QWT. In addition to the remote control, you can operate the unit via the Midea Air app, which also supports Amazon Alexa and Google Assistant for voice commands.
Several buyers have noted that the unit's heating mode isn't particularly effective. We didn't independently verify these claims, as we don't test an A/C unit's heating performance, but it's worth keeping in mind if effective heating is a must-have in an A/C.
