Rated 5 out of 5 by from Does The Job! Our kitchen and dining room have a passage between them. We knew 2 A/c's would be wasteful but we alos knew an underpowered unti wouldn't take care of business. The 10,000 BTU LG/LW1015ER was up to the job and then some. Both dining room and kitchen have stayed cool desoite the heat of the Summer of '16, here in the NorthEast. Bravo LG...bravo!

Rated 5 out of 5 by from Fully satisfied I got this product on sale. This was an excellent purchase. This product exceeded my expectations. I use it in the upper part of he house it has a bedroom an additional room before the bedroom. This unit cools the whole area and the adjustable temp is the best. It is quiet and is perfect for that part if the house. I stay in Michigan and this summer heat has been brutal. This product kept the area very comfortable.

Rated 4 out of 5 by from Great cooling power! I bought this to replace an older unit that was not powerful enough to cool the area I wanted it to. This model is doing a great job of cooling the entire area I want it to cool! I wish it wasn't so noisy when it runs, but I think that's true of every air conditioning unit. I'm very happy with the product overall.

If you needed exactly 20,000 BTU or 22,000 BTU, there aren't any with that BTU Rating...^IFV

How do you reset the clean filter light

Asked by: Brad 58
We regret the inconvenience you have experienced with this air conditioner and its features. The ‘Clean Filter’ LED will light up to notify you that your filter needs to be cleaned. After cleaning the filter, press “Temp ^” and “Temp v” buttons together to turn off ‘Clean Filter’ light. The filter reset must be done from unit control panel. The buttons on the remote control will not perform in this fashion.

I can not get the delay timer to work. Manual seems pretty straightforward. Any special instuctions to have this feature work? or do I have a defective unit?

Asked by: dcos1
While the unit is RUNNING, each press of the TIMER button adds an extra hour to how long the delay is before the air conditioner DEACTIVATES. While the unit is INACTIVE, each press of the TIMER button adds an extra hour to how long the delay is before the air conditioner AUTOMATICALLY STARTS.

how many louver directors for lw1015er. In other words can you direct half air flow in one direction and other half in the other horizontal direction(eg half to right and half to left)

Asked by: notonmyneck
We appreciate your interest in this air conditioner. The louvers have the ability to move all vents horizontally and vertically. This information is listed on page 18 of the owner’s manual. It does not have the ability to adjust multiple directions simultaneously.

High Pitched Sound

I recently exchanged a Friedrich 7800 BTU unit for the LG LW1015ER - the Friedrich did not have enough capacity to cool my room. I have limited window space - a French window where I had to remove a pane of glass, so width of unit is critical and cannot be over 20". So I chose the LG for its size. However, when cooling, it emits a very annoying high pitched sound. Your literature indicates this is normal for high efficiency units. However, the Friedrich was nearly silent in comparison with no sound like this. It is nearly intolerable - I feel like I may have to return this unit and go back the to Friedrich which was not adequate in BTU. Is there nothing that can be done about this? Brian Dube
Asked by: BrianDube
Brian, our unit is the same one you bought, you may want to exchange it, ours has no high pitched sounds at all. If I'm sitting right next to it I may have to turn the TV up a bit due to the fan . but no high pitch noises here.
