Rated 5 out of 5 by from Great value This unit is rated to cool about 550sq ft however our house is 1056sq ft. By closing off the bedrooms it does a nice job of cooling the kitchen, dinning room and living room. When it is over 100 degrees out side it keeps our area just right when we set it at 77 degrees. We use the auto setting and it works great. By installing the unit according to the instructions we have no vibration, you must use the supplied rubber cushion/strip and when the unit is on the high speed the noise is minimal, after all a unit of this size will not be totally quiet. Once installed we turned it on and it worked perfectly and cooled down the area quickly. If you have replaced your windows I strongly suggest that you look at the installation instructions on LG's web site very carefully. In our case we had to remove the lower window completely, it lifted right out, as the unit filled the space. The two window sill brackets, outside, were way to short and I had to cut two 2X4's to make a custom fit. If you are handy with tools you can install this unit in no time, the great feature is that the case can be separated from the unit making it very easy to install and fasten down the case first then slide in the unit. You should have a nice looking and secure unit.

Rated 5 out of 5 by from Quiet and Powerful! We have had several through-the-wall A/C units in our bedroom over the 3 decades we have lived in our house. Unquestionably our LG unit is the best of all. It runs very quietly but yet cools a large 2-room area extremely well. There are no cold or hot spots. The LG features a thermostat, a clean-filter reminder, and a choice of air-flow speeds. We have yet to use it to heat in the winter, but we expect it will do a great job when winter arrives. Thanks for a great product!

Rated 5 out of 5 by from Good Cooling and Heating This unit is great for a small to medium size room

Rated 5 out of 5 by from LW1216HR - excellent choice This unit was easy to install and has a CEER rating of 11.2 This unit is a heat pump and has additional heat if temperature gets below 45 deg. F. Good choice.

Rated 4 out of 5 by from Good investment This works great, the ones with side air discharge are very powerful, little bit more noisey than other units but worth it, and for a bonus you get heat in winter time too. Im really glad I got this model. Here is a tip people, buy the unit that it says you need on the chart (BTUs), thats why they have the charts for square footage. Why put a small unit under stress the whole time you use it if you are trying to cool too large of an area.

My unit keeps cycling the heat on and then off every 30 seconds and goes for about 30 seconds. The room feels okay so why does it keep doing this? It's running our electric bill and nerves up add is making it hard to sleep.

Asked by: jdb09041978
We regret your displeasure with the operation of this air conditioner. The heater is designed to cycle on and off again in order to maintain the set temperature. If the heater is activating that frequently, then it is suggested to search for a reason why the temperature might be falling enough to trigger the heat again. Is the room open to other rooms that it might be over-compensating? Is there an air leak allowing cold air into the room? If this does not resolve the matter, please contact our Customer Interactive Center at 800-243-0000 to troubleshoot the matter further.

How do I clean the filter ?

Asked by: KeyA
We appreciate your interest in the proper maintenance of this air conditioner. According to page 20 of the owner’s manual, check the filter at least twice a month to see if cleaning is necessary. Trapped particles in the filter can build up and block the airflow, reducing cooling capacity and causing an accumulation of frost on the evaporator. To clean the air filter: 1. Lift the inlet grille upward; 2. Remove the air filter from the front grille by pulling the air filter up slightly; 3. Wash the filter using lukewarm water cooler than 104 degrees Fahrenheit; 4. Gently shake the excess water from the filter and replace.

How can I drain water that is being held by the ac unit 

Asked by: Chaka559
This air conditioner is equipped with a slinger fan. The fan has an outer ring that runs through the water that collects in the base pan. That condensate is then picked up by the fan and expelled onto the condenser coils, making the machine operate more efficiently. In humid weather, excess water may cause the base pan to overflow. Remove the drain cap, from the back of the cabinet, and secure a drain pipe in order to drain the excess moisture. Information about this can be found on page 19 of the owner’s manual.

How do I shut off red light that has to do with filter

Asked by: gene25
The CLEAN FILTER indicator light can be deactivated by pressing the TEMP UP and DOWN together. This must be done on the control panel. The buttons on the remote control will not reset this light.
