LG LW1817IVSM Review.

The LG brand has a reputation for high-quality, air conditioning units.

Recently they introduced their newest line of WiFi “smart” window AC units — they connect directly to your home internet and controlled w/ your smartphone (w/ the LG SmartThinkQ mobile app).

Smart window AC units are offered in 3 sizes:

LG Dual Inverter Cooling Power Room Size
LW1019IVSM9,500 BTU350 - 450 sq. ft.
LW1517IVSM14,000 BTU500 – 800 sq. ft.
LW1817IVSM18,000 BTU800 – 1,000 sq. ft.
LW2217IVSM22,000 BTU1,000 – 1,300 sq. ft.

Each includes a dual inverter — super fast cooling in big rooms and quieter operation than other 18000 BTU units.

For my review I’ll focus on the LG LW1817IVSM (18,000 BTU).

Using revolutionary dual inverter technology, LG window air conditioner units are also energy efficient.

In terms of energy consumption, each unit operates 25% more efficiently than minimum Energy Star requirements.

LG LW1817IVSM Window AC Review:

The Dual Inverter units use cutting-edge dual inverter technology.

Designed with twin rotors and specialized compressor to deliver faster cooling power + lower energy usage.

Dual inverter technology also cuts out extra noise, creating an ultra quiet performance — buyers confirm that it’s much lower noise than their previous window-mounted unit.

AC Model: LW1817IVSM

Cooling: 18,000 BTU

Room Size: up to 1,000 sq. ft.

This ultra-quiet air conditioner runs as low as 44 decibel level, so users find it is noticeably less loud and intrusive in their homes.

Noise Level (dB): 44 – 53 decibels

t’s one of the quietest window air conditioner units on the market.

Unlike other AC units that cycle on and off abruptly, this LG model continually adjusts compressor speed to create a sustainable, cool environment.

Buyers also confirm that it’s easy to install (and doesn’t require special tools or skills).

Installation: 10 – 15 mins

For easier home-use, sync it w/ Amazon Alexa or Google Home for voice command control.
