LG LW1512ERS Window Air Conditioner Review

Overall Rating:
3.8 out of 5 stars
LG LW1512ERS window mounted air conditionerClick to Enlarge


The window mounted LG LW1512ERS air conditioner is quite simply a beast when it comes to cooling a room. Perfect for areas where temperatures get uncomfortable during the summer months, this unit has been designed to get the temperature in a room down, and quickly. As you would expect from LG, the additional features with this model make it one of the best for large rooms up to 800 square feet.

Review Details

You have an incredible amount of power behind this unit. With a capacity of 15,000 BTU and the ability to remove up to 4 pints of moisture each hour the LW1512ERS will keep you cool and comfortable all summer long.
If you’re worried about energy consumption, LG have thought about this. This model is energy star rated and comes with an energy saving option. In addition, you benefit from a 10.8 energy efficiency ratio (EER) and 24 hour on/off timer which all helps towards keeping bills down.

Because this is a window mounted air conditioner, LG has also included their patented Gold Fin anti-corrosion coating, which provides a shield so the unit will last longer.

What We Liked

  • Cool Air Where It’s Needed Most
    With 3 cooling/fan speeds and 4 way directional air controls, it’s possible to have cool air where you need it most. The LW1512ERS has louvers that can be moved up/down and left/right.
  • Easy to Use Controls
    You can choose your fan/cooling speed, set the timer and all the other functions by making use of the electronic touch control panel, or use the full function remote control.
  • Cool Air on your Schedule
    The LG LW1512ERS is fitted with a 24 hour on/off timer which means you can set it so the air is at the desired temperature when you arrive home.
  • Thermostat Control
    All that’s needed with this window air conditioner is for you to set the desired temperature and leave the unit to do the rest for you.

What We Didn't Like

  • Weight
    It should be noted the LW1512ERS is not in the least bit lightweight. In fact it comes in at just over 100lbs. Keep this in mind when making a purchase because help may be needed for installation.
  • Durability
    There have been many complaints this unit does not last as long as they would expect. Generally this is down to technical errors that occur well after the warranty has expired, so you might want to consider to upgrade the guarantee (most merchants offer this option).


The LW1512ERS window air conditioner from LG certainly lives up to its 15000 BTU capacity. It cools an area up to 800 square feet very efficiently. Unlike many other models of this size it also dehumidifies an incredible amount of moisture in a 24 hour period. LG has also managed to keep a sense of style for a unit that’s so powerful and it won’t look out of place in the home.
