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 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 |

Rated 4 out of 5 by C14 Made it through one hot summer
So far, so good. We used this on the first floor at one end of an open floor plan. It managed to keep the humidity down and the temps in the 70's, even when it was 90's outside. It's not quiet, but it's a big AC unit, so I suppose it's what I expected. I used fans to circulate the air through the home and back to the unit. Really heavy, but the bracket and sleeve work very well once you figure it out. Install the bracket and sleeve, then slip the main until in. An average man can probably do it alone - I could - but pulling the main unit in and out is really better done with a partner.
Overall, satisfied with the purchase after one summer.

Rated 5 out of 5 by Ducklady Beats the Heat!
I purchased this a/c to replace my other unit which just couldn't keep my house comfortable in the hottest weather. We had a heat spell, and my 4 a/c units could not keep my house comfortable when it got in the 90's. I replaced two units with LG a/c, and noticed the difference. I then only needed 3 a/c units running to cool my house. But when I switched the LG units to "DRY", my house was noticeably cooler with only TWO units! They take out the humidity, cool my house, run less frequently (the thermastat does all the work), and I'm sure my electric bill will see the difference. I wish I had purchased these units before! I will definitely purchase LG when it 's time to replace any of my other units.
