Runs great!
on October 15, 2026
Posted by: Tabs83
Was easy to install. Have had for a few months now and it is working great. Love the oscillating vent for even airflow. Cooling has been great so far. Air filter is easy to remove and clean. It is a little noisy but easy to deal with for how great it runs.

We will definitely share your feedback regarding noise levels with our product team. If you ever need any assistance down the road, please feel free to reach out to us at @LGUSSupport. #LifesGood ❤️ —Rich

We bought this during the heat of the summer and it has done great keeping up! Has worked great! Very impressed, and was simple to set up. Haven't tried the heater yet, but we will soon as winter hits! I'm sure it will do great just like the A/C!
