The LG LW1024RD 10,000 BTU Window Air Conditioner is a remote-controlled unit for medium rooms up to 450 square feet, about 18′ x 25′. LG pitches it for larger bedrooms and living spaces, with a listed noise level of 52 dB in low mode. It is a straightforward, non-smart option among mid-size conventional window air conditioners.
It covers the everyday essentials: electronic controls, a remote, 3 cooling and fan speeds with Auto Cool, a 24-hour timer, 4-way air deflection and Auto Restart. The main consideration is its 57 pound weight. We evaluated it based on the manufacturer’s specifications.
Our Verdict
This LG is a dependable choice for a living room or large bedroom. Its strongest points are the remote and electronic controls, 3 cooling and fan speeds with Auto Cool, a 24-hour timer, 4-way air deflection, Auto Restart, a washable filter and a listed 52 dB in low mode. It holds 3.8 stars from 106 ratings.
The trade-offs are weight and features. At 57 pounds it needs two people to install, and there is no inverter, Wi-Fi or eco mode. If you want simple, remote-controlled cooling for a room up to 450 square feet, it is worth considering.

Cooling Capacity and Room Size
LG rates the LW1024RD at 10,000 BTU for medium-sized rooms up to 450 square feet, about 18′ x 25′. It names larger bedrooms and living spaces as the ideal fit.
The 4-way air deflection helps in a room of this size by directing airflow up, down, left or right. If your room is well under 400 square feet, a smaller unit may suit it better, since an oversized AC cools quickly and shuts off before removing much humidity.
The 18′ x 25′ room size LG gives is a useful reference. If your living room is roughly that shape, the 4-way deflection lets you push air down the long side of the room rather than straight across the short side.
ENERGY STAR publishes this general guide for sizing a room air conditioner by floor area:
| Room Size (sq ft) | Cooling Capacity (BTU/hr) |
|---|---|
| 100 to 150 | 5,000 |
| 150 to 250 | 6,000 |
| 250 to 300 | 7,000 |
| 300 to 350 | 8,000 |
| 350 to 400 | 9,000 |
| 400 to 450 | 10,000 |
| 450 to 550 | 12,000 |
| 550 to 700 | 14,000 |
| 700 to 1,000 | 18,000 |
Adjust for your room: reduce capacity by 10 percent for a heavily shaded room, increase it by 10 percent for a very sunny room, add 600 BTU for each regular occupant beyond two, and add 4,000 BTU if the unit cools a kitchen. Source: ENERGY STAR.
At its listed 10,000 BTU, it lines up with rooms of about 400 to 450 square feet, which matches LG’s coverage claim.
Installation and Fit
The listed window opening is 22 to 36 inches wide with a minimum height of 13 inches. Window curtain panels, the remote and batteries are included.
The cabinet measures 19.38 inches deep, 19.57 inches wide and 12.33 inches tall, and weighs 57 pounds. Plan on two people: one to hold the unit and one to lower the sash and fasten it. Follow the manual and plug it into a standard 115V outlet.
The relatively low 12.33 inch height leaves more of the window clear than taller units, which helps keep some light and view in a living room.
Noise, Energy Use and Efficiency
LG lists sound levels as low as 52 dB in low mode, and the specifications give the same figure. That is quiet for a 10,000 BTU unit and works well in a bedroom on the lowest setting.
The listing gives an efficiency figure of 11.4, labeled as SEER, and a power draw of 870 watts. The scroll compressor has no inverter. Auto Cool and the 24-hour timer help avoid unnecessary running, though there is no dedicated eco mode.
Controls and Smart Features
Electronic controls and the included remote let you adjust temperature and settings from anywhere in the room. You get 3 cooling and fan speeds plus Auto Cool, which adjusts the fan to maintain the set temperature.
The 24-hour timer lets you create a cooling schedule, and 4-way air deflection directs airflow where it is needed. Auto Restart turns the unit back on after a power failure without manual adjustments. There is no Wi-Fi or app control.
For most living rooms, the remote and timer cover the main needs: start cooling before you get home and switch the unit off late in the evening.
Maintenance and Drainage
The removable, washable filter makes cleaning simple. Rinse it regularly during the cooling season to keep airflow strong and efficiency steady.
LG notes the unit can cool, dehumidify or circulate air. The listing does not describe condensate drainage, so check the manual for how water is handled and for seasonal storage steps.
