The LG DUAL Inverter LP1419IVSM is a portable A/C unit designed for medium-sized and large rooms. It has an advertised coverage of 450 ft² (42 m²) and a capacity of 10,000 BTU/hr. It features LG's dual-inverter compressor technology but has a basic single-hose design. It comes with a remote control, and you can also operate it remotely using the LG ThinQ app. The latter also offers integration with Amazon Alexa and Google Assistant devices for making voice commands.
Our Verdict
The LG DUAL Inverter LP1419IVSM is only okay for use in large rooms. Its capacity is generally sufficient for spaces like playrooms or larger bedrooms and offices, but it'll struggle to quickly cool large living rooms or open-concept apartments. Its single-hose design is also very inefficient, causing it to consume more energy than some dual-hose alternatives with similar or greater capacity. On the upside, it runs very quietly for the most part, and it won't be a disturbance if you have it running while you're entertaining company or simply watching TV.
-
Quiet overall operation.
-
Single-hose design severely limits overall efficiency while cooling.
-
Will struggle to cool especially large spaces.
The LG DUAL Inverter LP1419IVSM is a satisfactory choice for cooling small rooms. It's a very bulky unit, which can make it a bit of an obstacle in really tight bedrooms or to stow away in smaller closets when it isn't in use. While it does a great job of maintaining ambient conditions in undersized spaces, thanks to its inverter compressor, its single-hose design severely impacts its overall efficiency. This makes it a far more power-hungry unit versus most dual-hose models with inverter compressors.

Bulky dimensions.

Efficiency while maintaining setpoint is bad.
The LG DUAL Inverter LP1419IVSM's overall efficiency is poor. It doesn't have a dedicated intake hose, and instead draws in air from the room it's cooling to chill its running compressor. This generates negative air pressure and encourages warm outside air to be sucked into the room it's cooling, forcing it to work hard during both cooling and maintenance cycles.

Single-hose design severely limits overall efficiency while cooling.
-
Efficiency while maintaining setpoint is bad.
The LG DUAL Inverter LP1419IVSM is decently flexible for use in a variety of spaces. Its dual inverter compressor runs very steadily while maintaining the setpoint, so you won't experience any unpleasant swings in temperature or perceived humidity. That said, this is a pretty inefficient unit due to its single-hose design.

Efficiency while maintaining setpoint is bad.
The LG DUAL Inverter LP1419IVSM is impressively quiet. Like many inverter units, it can occasionally put out a high-pitched chattering noise, but it isn't too distracting overall. During normal operation, it's quiet enough to be masked by most sources of household noise.

Compared To Other Air Conditioners
The LG DUAL Inverter LP1419IVSM is a high-end portable A/C designed for medium to large spaces. It's a feature-packed unit with a unique dual-inverter compressor, which is nominally supposed to allow for more efficient running at a broader range of speeds versus a single inverter compressor. Granted, this unit is very effective in maintaining the desired temperature and a consistent ambient humidity level, but it's hamstrung by its inefficient single-hose design. This puts it in a very awkward position for an A/C at this high a price point, and it's simply outperformed in every metric by dual-hose alternatives like the Midea Duo MAP12S1TBL or the Whynter NEX ARC-1230WN.
The Whynter NEX ARC-1230WN outclasses the LG DUAL Inverter LP1419IVSM in every respect. The Whynter's dual-hose design gives it a massive advantage in terms of cooling efficiency, allowing it to cool a room much faster and with much lower energy consumption. The LG is a little more compact, but it's still a fairly bulky appliance.
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.
The LG DUAL Inverter LP1419IVSM is a more energy-efficient option than the Hisense AP1022HW1GD. Its inverter compressor can maintain a lower speed rather than cycling on and off, minimizing any swings in temperature and humidity once it's achieved your desired setpoint. That said, its upfront energy cost is rather high, even more so than that of the non-inverter Hisense.
Test Results
This unit's capacity is okay overall. It's well-suited for use in bedrooms or offices, but it simply lacks the capacity to cool larger spaces, like living rooms or open-concept spaces. A window unit with comparable capacity, like the Friedrich Chill Premier Inverter CCV08A10A, will cool a comparably-sized space in considerably less time.
This unit's compressor automatically modulated down to a slightly lower speed early in the cooling cycle while in testing. Since there's no way of manually forcing its compressor to maintain its max speed, we can only assume that its actual capacity is marginally higher than the data here indicates.
This unit's efficiency while cooling a room is poor. As a single-hose unit, it draws in air from the room it's attempting to cool, generating negative air pressure and allowing warm air from outside to seep back in, requiring the unit to work even harder to cool the space. As a result, this unit's energy demands are much higher than dual-hose units with separate intake hoses, like the Whynter NEX ARC-1230WN.
The LG DUAL Inverter LP1419IVSM is energy inefficient while maintaining a temperature setpoint. While its dual inverter compressor can run at a constant speed, below its max capacity, it's still forced to work very hard due to its inefficient single-hose design.
The LG DUAL Inverter LP1419IVSM does an excellent job of keeping ambient humidity levels stable while maintaining a setpoint. Its compressor runs at a constant speed while maintaining a setpoint, so there are no big swings in humidity while the unit runs. Consequently, your room should feel comfortably dry.
High-pitched operating noise from the compressor is a common complaint for inverter A/C units. However, as stated in this model's user manual, this noise is completely normal once the unit enters a cooling cycle.
This A/C unit occasionally exhibits noise spikes that climb to a very noticeable 65.5 dBA, though these bursts last less than a second and aren't too disruptive.
As is befitting for a high-end portable A/C, the LG DUAL Inverter LP1419IVSM is packed with features. You can operate the unit remotely with the LG ThinQ app, which also supports Amazon Alexa and Google Assistant devices for making voice commands. Beyond that, you can toggle between four different fan speed settings.
