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.

Room SizeBTU
Sq. Ft.Sq. m
15014 up to 5,000
16515 5,200

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 31 reviewers.
Rated 3 out of 5 by Product Lacks Protective Grill for Condenser Coil I would not recommend this window unit because LG has chosen not to install the protective grill over the exposed condenser coils. The thin aluminum fins are subject to damage without this protection. My previous LG unit (purchased in 2004) was also a 10,000 Btu and it had the protective grill. Obviously who ever made the decision at LG to save a couple of dollars and not install this grill knows absolutely nothing about air conditioners. Any size air conditioner needs this protection and I would recommend not purchasing one that lacks this essential protection for the condenser coil 4/5/14
Rated 5 out of 5 by Window air conditioner Just installed a new 10,000 btu air conditioner model LW1014ER. It is very quiet and installation was very easy. 5/27/14
Rated 2 out of 5 by Quality not great-would not purchase again Unit cools well and has good air flow but very noisy. Not nearly as quiet as previous years models. Cracks on front grill. Quality is slipping. Does have improved filter removal compared to previous models. 6/7/14
Rated 5 out of 5 by Small But Efficient I have a smaller model in my middle room and because of how that LG Room air conditioner works, I thought I would try this one for my larger Master bed room. I wasn't disapointed. This works great and cools off the larger master bed room in no time. Now I own 3 LG air conditioners and all work great. 7/7/14
