Rated 5 out of 5 by from THE BEST BUY EVER!!!!!!!!! I recently purchased a new home in San Diego without a central air unit. My home is 2k sqft. with 2 story ceilings. I purchased this ac because it was the biggest I could buy for 110 volts. My house temp would be in the 90's on a normal day with high humidity. I installed this air conditioner in my downstairs family room and when I turned it on........ Instantly the air begin to change because it blows VERY STRONG and COLD... My unit ran for 2 months non-stop from the first day I opened it. It would keep the house cool with the help of air circulations but they were noisy. I am so pleased with this unit that I purchased (4) 11,000 btu LG portable air conditioners to go in each bedroom. I set them all to 74 and they work together and bring my home to 74 degrees... I am MORE than happy with LG products .. My 15k unit ran non stop for 2 months with no breaks until I recently purchased the other units. I made up my own central air system in my home by using LG products. I even bought my son a portable 10,000 btu for his apartment. THANK YOU LG FOR MAKING GREAT PRODUCTS...

Rated 4 out of 5 by from Works well We bought this same model 2 years ago, and had problems with mold (not the product's fault). I like the new filter and the clean filter option. Cools a 1000 foot space easily.

Rated 5 out of 5 by from Gets the job done! We were seeking an alternative to central air and were very pleased by this products performance. Cools our entire 1st floor quickly. Product is pretty heavy. Having two people to install is very helpful. Happy we chose this unit!

Rated 5 out of 5 by from Great room AC This is a great AC for a single room would not try and do several rooms with it.

Rated 2 out of 5 by from Noisy The unit is either faulty or is of poor design. The front filter bracket does not sit flush with the system. I have also found that it is very noisy in operation. When set in the Econ mode you can really hear the compressor kick on.

Does this air conditioner draw fresh air from outside to the room or it's just recycling the air indoor?

Asked by: Sim0n
The LG Window Air Conditioner, Model # LW1514ER has a Ventilation Lever on it that must be in the CLOSE position in order to maintain the best cooling conditions. However, when fresh air is necessary in the room, this lever can be set to the OPEN position and a damper is opened and room air is drawn out...^IFV

The part that says clean filter has a red ligjt, i cleaned the front filter and i still didnt go off is there another filter

Asked by: Lisha
This flashing red indicator light is a normal operation for certain models. On some newer models, the POWER INDICATOR will begin to flash when it is time for the air conditioner filter to be cleaned. It is possible to reset this indicator light by unplugging the unit for approximately 3 minutes, and then restoring power to the system.

The instructions shows the ventilation lever must be closed on order to maintain best cooling. I cannot locate the lever like in the diagram. Where is it?

Asked by: Fays1
We appreciate your interest in this air conditioner. The ventilation lever is located within the air exhaust duct. It is a small, plastic stick which can be pulled outward or pressed inward to control the internal vent.

I too would also like to know if this unit can be wall, versus window mounted.

I just watched the video that accompanies the information for this unit, however, the video does not really apply to this unit because the video specifically states that it is for 8,000 - 10,000 BTU units. It then gives a "disclaimer" that "installation of a 12,000 BTU unit may differ"; no where does it make reference to a 15,000 BTU unit, which is what this unit is. The video says do not wall mount this unit, but as I just stated, it refers to 8,000 - 10,000 BTU units. I'm thinking the reason a unit should not be wall mounted is because wall mounting may block the vents. However, if ALL the vents are free from blockage and accessible, can't the unit be mounted in a wall versus a window? Thank you.

I have an older LG 15,000btu window unit mounted thru a wall in a mobile home for about 5 years with no problems.I installed it myself.

My unit won't cut on could it be the breaker voltage cause I plug my fan up and it works fine 

Asked by: Jbird23
We regret the trouble you have experienced with this air conditioner. Yes, it is possible for the amperage of the circuit to affect operations of this air conditioner. It is for this reason that a dedicated circuit of 125V @ 60Hz with a 15A fuse is recommended for operations.

Asked by: Roberta Bonfiglio

Air conditioner amp usage

Does this unit use different amperage when running? How much amperage does this draw when running but not cooling, and how much amperage does this draw when full cooling (compressor) is running?
Asked by: BryanB15845
BryanB15845, we appreciate your interest in the LG Window Air Conditioner, Model # LW1514ER. This unit is listed at 12.0 Amps but that probably is the amperage for the unit when it is running. The amperage for when the compressor kicks on or when the unit is just running is not specified but can be calculated from the information that is on the data template that is attached on the unit. On that data tag, you will find the FLA (Full Load Amp) rating for the fan which is usually around 1 amp so that does not consume that much power. You will also find on the data tag is the RLA value, this is the Rated Load Amps and is the amount of current (amps) your compressor should consume if it is operating normally. You may also have an LRA (locked rotor amps) value. This is how many amps your compressor would consume if for some reason it jammed up and it is the maximum possible amperage draw of the compressor. Once you have those amperage values for your compressor and fan, add them together and that is how many amps the unit as a whole consumes when it is running...^IFV
