About this item

Product details

The LG LW1521ERSM1 is not only cool...it's SMART! Cool your home from anywhere using LG ThinQ technology to control your air conditioner with your phone or use with Amazon Alexa and Hey Google to have control with the sound of your voice. This quiet unit is ideal for cooling large rooms up to 700 sq. ft. The unit has 3 cooling and fan speeds and a 24 hour timer to create a cooling schedule. 4-way air deflection lets the flow of air be directed where it's needed most whether cooling, dehumidifying or just circulating air. If there is a power outage, the auto restart feature will automatically turn your unit back on when power is restored. Other features include a remote control, easy window installation kit, slide-out (washable) filter and a check filter alert. LW1521ERSM1

Works as advertised.

Cools down our bedroom quickly. It does have a bit of a thud when the cooling turns on and off. It's not terrible, but worth noting The fan noise is average, the display is bright but can be shut off if desired. All and all it's a decent air conditioner for the price. I would buy again.

Didn't really get to use this unit but a couple of weeks before having to turn it off because the weather changed. I like the remote, as it's hard to get to the unit in my room. I don't like the vents, they blow up and I prefer for them to blow out into the room, from the front of the unit.

Nice quality air conditioner

I need a new air conditioner and this is a nice quality air conditioner. I have other LG appliances that I've been highly satisfied with so I picked their air conditioner. FedEx quickly %26 carefully delivered. Box had straps so it was easier for me to carry into the house. I installed it with no problems. It cooled my room down quickly and is now on energy saver and is maintaining a comfortable temperature I chose without continuously running. A super buy, very happy with it. Thank you
