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.
About Duct-Free Systems
A duct-free system, also known as a "split" air conditioner system, is made up of or includes two components: an indoor unit to deliver conditioned air to the room, and an outdoor unit located outside of the house. Compact refrigerant lines run between the two units, eliminating the need for bulky ductwork. Duct-free systems are ideal for older homes that have no ductwork, room additions, or areas in homes that just never seem to be the right temperature or are never comfortable.
LG duct-free systems are available in a range of sizes and styles - including systems that can heat and cool multiple rooms with a single outdoor unit to fit almost any need. The indoor units are available in many different types to fit with the look and feel of your home.
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 Size | BTU |
|
| Sq. Ft. | Sq. m | |
| 150 | 14 | up to 5,000 |
| 165 | 15 | 5,200 |
| 216 | 20 | 6,000 |
| 350 | 33 | 8,000 |
| 425 | 39 | 9,000 |
| 500 | 46 | 10,000 |
| 640 | 60 | 14,00 |
| 900 | 84 | 15,100 |
| 1,110 | 103 | 18,000 |
| 1,170 | 109 | 18,500 |
| 1,435 | 133 | 22,000 |
| 1,672 | 154 | 25,000 |
| 1,960 | 182 | 28,500 |
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.
This air conditioner has an Energy Efficiency Rating of 13.3 and has an estimated yearly operating cost of $56.28.
Your operating costs will depend on your utility rates and use. The estimated yearly operating cost is based on the 2011 national average cost of $.1109 cents per kWh for electricity and an estimated number of operating hours of 750 hours.

Rated 5 out of 5Â by Dick Excellent AC
I have a man cave over the garage, and it is not well insulated. There is not sufficient room between the studs to install a window unit, so I went to the split AC system. Installation is more expensive than a window unit, but the guys did a great job. The unit has so many options like economy saving, a fan that not only blows up or down but also swings back and forth. I have it set to blow up and swing from side to side. I am having trouble setting the room time, but that is not important. The plasma feature further filters the air and the clean feature will clean the unit. That remains to be seen.
AJMadison needs to improve their shipping information. I received a notice it had been shipped but no tracking number. It held up installation for almost a week.

Luxuries of a Mini-Split (Ductless Split System)
Ductless Split Air Conditioner & Heat Pump products offer wide versatility in solving your cooling and heating requirements. The Indoor unit (evaporator) is mounted inside the room, and usually goes very unnoticeable. It is connected to the outdoor unit (condenser) via refrigerant lines & inter-unit wiring through a 3-1/2" opening in the wall. Since no ductwork is required, installation is simple, fast & efficient. There is no need to use up window space or cut large openings in existing walls, which could undermine the integrity of your structure, and even pose security risks. Since the Rotary compressor is located in the outdoor unit, compressor operating noise is virtually eliminated from the indoor. The indoor unit has been uniquely designed to provide Whisper Quiet operation while delivering comfort throughout the room(s). In addition, rotary compressors provide efficient, powerful cooling at the lowest noise levels in the industry.
