Smart and Low Energy Consumption

We’ve had this for some time and can’t fault it! It is so cheap to run and whisper quiet. The outdoor unit is low noise also which is important too when we entertain outside. I love that it has Wi-fi and I can control it with our Google Home and even turn it on before we get home to cool or warm the room. The real time energy usage is crucial to us as we have Solar and tailor our usage to get the most out of our Solar System. It always maintains a constant temperature so we don’t have to keep making adjustments. The digital display on the front is a handy feature too! I couldn’t be happier and feel confident with a 10 year compressor parts warranty.

A Canadian dying of heat ...

Alright so … I am a Canadian from the freezing eh. I think it is deadly hot when it gets above 25 degrees. I moved here 3 years ago for university and NEVER did I EVER imagine that Australia would be this hot.

I shower and sweat; I walk somewhere – I sweat. Lately it’s been so hot because of the fires in Australia that you will barely see me outside – I am hiding inside with my air con. I put that aircon to the lowest it can go and all in the world is content! I absolutely love having this air con and I don’t know what I’d do without it! Probably did of heat stroke in my own house!

You think it’s dramatic but I’m serious. I come from snow. In all seriousness I love Australia and I love this aircon.

Initially I was sceptical about LG but I bit the bullet and bought one and I’m so glad that I did after them 35 degree days outside on the field I’m so glad that I can come inside. I turn the aircon on and within minutes it’s like Antarctica. This aircon would be my one true love.
