Window air conditioners work by pulling in the hot air from your room, filtering out any dust or unwanted particles, chilling it, and releasing it back into your living space. This is a simplified explanation of the whole process, and does not consider advancements such as inverter technology that you’ll find in models such as the LG LW1517IVSM dual inverter window air conditioner. Whether or not this is a feature that’s enough to rank it as the best window air conditioner around is still up for debate, but if you get to the end of this review, you’ll have a perfect idea of what the LG window AC unit is capable of offering. We hope that you will also be able to compare it with some of the top-tier air conditioners on the market today.

The LG LW1517IVSM has a 14,000 BTU rating, and what this means is that the LG air conditioner has enough power to efficiently get rid of hot air from a floor area of up to 800 sq ft. This makes it perfect for a mid- to large-size conference hall, or outdoor event. The use of inverter technology also gives the LW1517IVSM air conditioner an edge over the Frigidaire 8000 BTU Air Conditioner, for example, because it can run its compressor motor at variable speeds, making it a lot more energy-efficient. The managed running of the motor also guarantees quiet operation, and with its fans having four settings, you’ll be able to easily customize it according to your preferences. And if you prefer a smaller unit, this model’s predecessor, the LG LW1017ERSM, will do you just fine, given it’s also fairly quiet with a rating of 52dB.

Energy Efficiency

The LG model LW1517IVSM dual inverter compressor is potentially its best highlight, as it drastically reduces the amount of energy it needs to run compared to other window air conditioners. LG claims that this window unit is up to 25% more energy efficient than the minimum Energy Star certification requirement, making it a much better option to go for compared to the LG LW8017ERSM if your goal is to save on energy costs. Another energy-efficient unit you may want to check out is the LG LW1816ER model, which has both an energy saver mode, and a 24-hour programmable timer.


As hot air from the room is pulled into the LW1517IVSM dual inverter air conditioner, all the unwanted dust particles from the room get filtered out, making the air conditioner a perfect tool for cleaning up the air in your room. Unlike the Frigidaire FFRA0511R1 central air conditioner and other AC units, it does alert you when it’s time for an air filter change, and making that change is important to guarantee top working condition. If all this talk about filtration and BTUs still makes you think, “How does an air conditioner work exactly?”, then consider giving our guide a read so you can understand what makes a unit actually function.
