Cools fast, quiet and looks great

I bought this last year. I live in the outback with a very harsh environment I picked LG for the quality.

Love the Wi-Fi capability

I recently had the WS18TWS installed at home, just in time for upcoming summer. My home gets really hot on the sweltering days and I finally decided from now on I wouldn’t suffer the heat. We’ve already had a few hot days and I had the opportunity to run the air conditioner and wow was I impressed. Even on the low fan setting, either the fan oscillation turned on, this awesome machine cooled my place down in just a few minutes. I set it to auto and for the rest of the night my place was a cool and comfortable 20 degrees and finally I had a good night’s rest. one of the features that I really love is the smart phone app which allows me to control the unit from anywhere. I can be on the way home from work and if it’s been a hot or cold day I can set the desired temperature from the convenience of wherever I am and know that when I arrive home the climate will be just as I desired. No more arriving home to a hot and humid home in the summer for me! So, do yourself a favour and say goodbye to uncomfortable nights and freezing winters with an LG air conditioner. You’ll be asking yourself why you hadn’t sooner.
