LG Energy Star Window Air Conditioner In a world where convenience is now a priority to be considered when making a purchase, why should this same convenience not apply to your window air conditioner as well? With today’s growing smart-home technology, you now have the option to control your window air conditioner.

You may be wondering why you would need a smart air conditioner. You already have a smart thermostat in your house controlling your home’s central heating and air. Isn’t that enough? Convenience has never been as practical as now!

Imagine you are on vacation and you get an alert on your phone from your smart thermostat notifying you that your thermostat is not working. The remainder of your home connected to smart devices is working as they should. You realize that your central air conditioning has gone out while you are on vacation during the hottest time of year. The house is going to be stifling when you arrive back home.
