The LG LW6024R 6,000 BTU Window Air Conditioner is a compact, remote-controlled unit for medium rooms up to 250 square feet. LG uses a 10 by 25 foot room as its example. It combines digital controls, a 24-hour timer, an Auto Cool setting, 2-way air deflection and auto restart. Among conventional window air conditioners, it is a simple, well-known choice, with 3.6 stars from 199 ratings.
LG lists sound levels as low as 52 dB in low mode. The main limits are 2 cooling and fan speeds and no smart features. We evaluated it based on the manufacturer’s specifications.
Our Verdict
This LG is a sensible pick for a bedroom, home office or small living room. Its strongest points are the remote, the digital control panel, the 24-hour timer, Auto Cool, 2-way air deflection, auto restart, a removable washable filter with a check filter alert, and a compact 37 pound cabinet that fits windows as short as 12 inches.
The trade-offs are typical of a basic unit: only 2 cooling and fan speeds, no inverter, no Wi-Fi and no heat. If you want quiet, remote-controlled cooling with a timer for a room up to 250 square feet, it is worth considering.

Cooling Capacity and Room Size
LG rates the LW6024R at 6,000 BTU for medium rooms up to 250 square feet. That covers a bedroom, a home office or a small living room.
The Auto Cool setting adjusts operation to hold the temperature you set, so you do not need to switch speeds by hand. The 2-way air deflection lets you direct airflow where it is needed, whether you are cooling, dehumidifying or just circulating air.
With only 2 cooling and fan speeds, fine control is limited. For most bedrooms and offices, high to cool the room quickly and low to hold it is enough.
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 6,000 BTU, it lines up with rooms of about 150 to 250 square feet, which matches LG’s coverage claim. In a sunny room near 250 square feet, a slightly larger unit may hold temperature more easily.
In a bedroom well under 250 square feet, the unit has some headroom. That lets it bring the room down quickly in the evening and then hold the temperature on the low speed, which is also the quieter setting.
Installation and Fit
LG lists a window opening of 21 to 35 inches wide and 12 inches high. An easy window installation kit and a trim kit are included.
The cabinet measures 12.83 inches deep, 17.31 inches wide and 11.13 inches tall, and weighs 37 pounds. One person can lift it, though a helper makes it safer to hold the unit while you secure it. The 12 inch height requirement means it suits many smaller double-hung windows.
Before you start, check that the sill is solid and that the window sash can close down firmly on top of the unit. A secure fit keeps the unit steady and reduces vibration noise.
It runs on a standard 115V outlet with a listed draw of 540 watts.
Noise, Energy Use and Efficiency
LG lists sound levels as low as 52 dB in low mode, which it says lets you sleep, work or relax in peace. That is a reasonable figure for a 6,000 BTU unit. Expect more sound on the high speed.
The listing gives an efficiency figure of 11.5, labeled as SEER. There is no inverter, so the compressor cycles on and off to hold the set temperature. Using the timer to avoid running the unit in an empty room is the simplest way to save energy.
Sealing gaps around the side panels also helps. Warm air leaking in around the unit makes the compressor run longer, so check the foam and panels at the start of each season.
Controls and Smart Features
The digital control panel is user friendly, and the remote lets you change the temperature and fan speed from your bed or desk. The 24-hour timer lets you create your own cooling schedule.
Auto restart turns the unit back on when power is restored after an outage, so you do not need to remember your previous settings. That helps keep a room comfortable while you are away.
There is no Wi-Fi or app control. For a bedroom, a simple routine works well: cool the room before bed with the remote, then set the timer to switch it off in the early morning.
Maintenance and Drainage
The filter is removable and washable, and a check filter alert reminds you when it is time to clean it. The included components list a mesh filter. Slide it out, rinse it, let it dry fully and slide it back in. A clean filter keeps airflow steady and helps the unit cool efficiently.
The listing does not describe condensate drainage. Check the manual for how water is handled and for storage steps at the end of the season.
