LG Dual Inverter Air Conditioner Review (LW1019IVSM): Fast and quiet


It’s almost impossible Don’t like LG’s double inverter window air conditioner (or if you want to call it by its official name, LW1019IVSM), especially the temperature in New York City this summer is as high as 95 degrees. It cools down my bedroom very quickly, and the sound is not too loud. It is also very smart. Before entering my apartment building, I opened it remotely so that I could walk directly into some happy places.

Ok. I do have to go to the hardware store to install it, partly because my windows are weird. However, once I installed the heavy object, it blew away my worries with a cold gust of wind.

The iceman is coming

It took me two days to install this air conditioner.I decided to install it at 11pm, it was my fault, but Is not My fault, I quickly realized that without some equipment, I would not succeed. The specification requires a double-hung window of a certain size, I have it. But in the middle of the window sill, there is a deep canyon. It is not flush with the inner door sill, which means there is no easy way to install the included L bracket to ensure its safety.

In fact, there are Included solutions Show that this is not a rare problem. So the next morning, I took some plywood from the nearby Home Depot, sawed it into the correct shape, and put it in to create a flat surface. I screwed the L-shaped bracket to the plywood and lifted the 63-pound object into place with the help of my partner.

The rest is relatively easy. The manual is fairly detailed and easy to follow; just prepare for possible window pranks.If you find yourself in a local hardware store, you can also pick one Metal bracket instead. The air conditioner will be placed more safely (this may also be a requirement in cities such as New York), and you don’t have to drill any holes.

LG contains a lot of foam and padding to seal any gaps around the air conditioning unit, but don’t expect the same level of sound insulation as when your windows are closed.noise will Leak (thanks, New York).It didn’t beat the soundproofing I experienced Midea U-shaped air conditioner, The window is further lowered, resulting in a smaller gap.

Cool party

What exactly does “dual inverter” mean? Ordinary air conditioners use a compressor driven by a single motor to exhaust hot air from the room, cool the air indoors, and transfer heat to the outdoors. Normally, the air conditioner will sense that the room is too hot, the compressor will rise to the highest level, and then turn off when the room reaches a suitable temperature.

However, LG AC has dual compressors and chambers, and its output can be adjusted. If the room only needs a certain amount of energy to cool the room, the motor does not need to rotate the ratchet all the time to work. This makes the device faster, quieter and more energy efficient. According to Energy Star, the energy used by this unit has been reduced by 27% Higher than U.S. federal standards,it Have done Once the room has cooled down, the temperature can be successfully maintained.

What you probably want to know most is How good It will cool down and save you from the next heat wave. The answer is very very good. On a particularly sweltering day of 94 degrees, this LG device raised the indoor temperature from around 84 degrees to a comfortable 73 degrees in one hour.
