Welcome To LG
LG Electronics USA Commercial Air Conditioning business is a leading player in the global air conditioning market, manufacturing both commercial and residential air conditioners and providing total sustainability and building management solutions. From consumer units to commercial air conditioning systems, LG provides a wide range of innovative products for heating, ventilating and air conditioning.

How To Choose A Room Air Conditioner
Compared to large capacity central units, room air conditioners have several advantages. The initial cost of a room air conditioning unit is significantly lower than the cost of central air. Because room air conditioners are designed for cooling small spaces, operating costs are reduced. And, room air conditioners can provide personalized temperature and humidity controls that central systems cannot.

Calculating Cooling Capacity
Cooling capacity is the critical factor in properly selecting a room air conditioner. Cooling capacity is measured in British Thermal Units (BTUs) and typical models will range in capacity from 5,000 BTUs to 28,500 BTUs.

Choosing an undersized unit will overwork the unit and it will not cool properly. Choosing an over-sized unit will cost more to buy and operate and it will not dehumidify properly.

We can help you to calculate capacity. Be prepared to provide specific information on:
  • Room Dimensions
  • A simple floor plan to show the location of doors and north-facing windows
  • The number of people it will serve
  • Sources of heat such as lamps, TV and appliances
  • An explanation of what's above the intended room
  • Your insulation provisions

Cooling Capacity by Room Size
Measure the length and width of the area to be cooled. Multiply the length by the width to determine square footage or square meters. Locate the room size in the chart below to select the appropriate BTUs. Then use the product information to select the unit for your room. When cooling rooms with uninsulated ceilings, great rooms, or southern or western sun exposures - step up to the next BTU size.

Air Conditioner Tips
Air flow - Keep air filters clean. Do not block air flow areas.

Roomside view - J-models feature concealed power cord storage, this eliminates excessive cord exposure when receptacle is located close to unit.

Wall Opening For RAB46/47/48 Cases
A finished opening of 26 1/8" x 15 3/4", clear of intrusions, is required. Keep clearance of 4" from side walls. Brick veneer or frame walls should have wood studding surrounding case to provide firm anchoring with screws. Case can be fastened directly to brick or block walls with screws sunk in lead expansion shields. NOTE: units should be caulked on all four sides of case to the building exterior to assure building integrity.

Product Reviews
Rated 4.6 out of 5 by 33 reviewers.
Rated 4 out of 5 by Overall excellent but cheap clips Overall very good AC, quiet operation. But the retaining clips on the bottom that hold the rail for the side louvres are very cheap plastic. I anticipate these will break off after 2-3 seasons if you're not careful. Which would render the AC useless unless LG can send you a supply of them to replace as you break them off installing/un-installing the AC. Otherwise would have been 5 stars across the board. The remote was cheesy too. You almost have to be directly in front of the AC for it to work. If you aim the remote at the AC from a side angle, it might not work, 6/7/14
Rated 1 out of 5 by Terrible Installation Instructions Just bought the LW1214ER Air Conditioner and tried to install it. Poor detail pictures and instructions. First instruction is insert the frame guide into the bottom of the cabinet. Picture looks like you should use a screw but no screw type given and you cannot tell where it wants you to insert it. Next instruction is fasten the curtains to the unit with 8 type A screws. Problem is it doesn't say or show which way curtains face and the type A screws are not sharp and will not go into the holes provided. I put the unit back into the box and will go buy a unit from another provider tomorrow. 6/30/14
Rated 1 out of 5 by The water does not drain from the housing properly While this air conditioner did cool the room well, that is lost in the fact that the water from running the air conditioner did NOT drain from the frame ('holder') that held the unit in the window. It WAS installed correctly, per the instructions that came with it. The unit leaked water all over the side of my house, because the fan blew the excess water that pooled in the center of the air conditioner out of the sides. The water would not drain, even though it was installed with a proper angle and into the carriage/housing that came with it. My husband tried to enlarge the TINY drain holes TWICE and the second time somehow the internal fan blade broke. It is only 2 months old (!!!) and it is no longer usable. The air conditioner will have to be replaced, unless I can find a repair person to fix the blades. I am very disappointed! What a waste of money! 7/4/14
Rated 5 out of 5 by GREAT value for the price This unit replaced an older, smaller but similar LG unit. The other unit was relocated to another room. This newer model is easy to operate and easy to maintain. I especially like the automatic feature that restarts the air conditioner after a power outage. The filter on this newer model is also MUCH easier to remove and reinstall. Although a higher BTU rating, this newer unit fit in the same size opening as the previous unit, and the electric bill is NOT noticeably higher. The remote control is also a nice feature. 7/5/14
