The LG 9000 BTU LP0910WNR Portable AC Review

If you need to cool a single room the LG Electronics 9000 BTU portable ac unit may be an option. (Reviews are mixed, so check the Pros and Cons section. –acboy) As with all portable ac units, it is portable, but it must be tethered to an exhaust hose. So when deciding where your new portable will go in your room, keep in mind that it will have to be near a window for proper ventilation. You’ll have to install a window kit also, which isn’t too difficult. If you are handy with a screwdriver, you should be ok. The window kit allows you to vent your portable air conditioner without letting your cold air escape. And lastly, with all portables, you’ll have to empty the condensate water tray as water will build up with use, especially if your hose is longer. On with the review.

How Large a Room Will The LG 9000 BTU Cool?
Up to a 300 square feet room. With all portables, it’s best to stay within the manufacturer’s specified room size. Don’t expect a 9000BTU unit to cool larger spaces or multiple rooms.

Bottom Line:
Reviews are decidedly mixed on this unit, so proceed with caution. There were usual noise complaints which are typical for most portables, but more concerning were intermittent auto shut-offs. In hot weather, some customers reported units shutting down–right when you nee them the most. Some customers also reported difficulty draining condensate water. If your room size is right at, or above, 300 sq. ft., you might want to consider the 12000BTU LG LP1200dxr model. Also, models by Supentown or Soleus get typically good ratings and might be worth investigating. For more info on portables in general, please see our ACboy Portable info page.
