LG LW6017R 6,000 BTU Window AC Review: Quiet Bedroom Cooling

The LG LW6017R 6,000 BTU Window Air Conditioner is a compact unit for bedrooms and home offices up to 250 square feet. LG markets it for low noise, listing 52 dB in low mode, and it adds a remote, a digital panel and a 24-hour timer. It sits in a popular middle size of conventional window air conditioners, a step above the smallest 5,000 BTU units.
It suits a medium bedroom, a den or a small living room. The question is whether its features and quiet low mode justify choosing it over a basic dial unit. We evaluated it based on the manufacturer’s specifications.
Our Verdict
This LG is a well-equipped choice for a medium bedroom or office. Its strongest points are the listed 52 dB low mode, 3 cooling and fan speeds, a digital control panel with remote, a 24-hour timer, 2-way air deflection, a filter light reminder and Auto Restart. A window installation kit is included.
The trade-off is that it is a conventional unit without an inverter, Wi-Fi or eco mode, and at 44 pounds it is heavier than many 6,000 BTU models. If you want quiet, remote-controlled cooling for a room up to 250 square feet, it is worth considering.

Cooling Capacity and Room Size
LG rates the LW6017R at 6,000 BTU for rooms up to 250 square feet, describing an ideal room of 10′ x 25′. That fits a medium bedroom, a home office or a den.
Compared with a 5,000 BTU unit, the extra capacity gives more room to handle a sunny window or a second person in the room. Still, if your room is close to 250 square feet and gets strong afternoon sun, you may want more headroom.
The 6,000 BTU size is also a good middle ground for a bedroom that doubles as a home office. A computer, monitor and lighting add heat during the day, and the extra capacity over a 5,000 BTU unit helps keep up without being oversized for nighttime use.
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 figure.
Installation and Fit
A window installation kit is included, along with the remote, a mesh filter and installation instructions. The cabinet measures 14.38 inches deep, 17.31 inches wide and 11.13 inches tall.
The listing does not give a reliable window opening range, so check the installation manual for the supported width and height before you order. At 44 pounds, a second person makes installation safer. Secure the unit with the supplied hardware as the manual directs, and plug it into a standard 115V outlet.
The compact 11.13 inch height leaves more of the window clear than taller units, which helps if you want to keep some light and view in a small bedroom.
Noise, Energy Use and Efficiency
LG lists sound levels as low as 52 dB in low mode and markets the unit for focused work and sleep. Expect higher sound on the faster fan speeds, and keep in mind that the seal around the window affects what you hear.
The listing gives an efficiency figure of 11.3, labeled as SEER, and a power draw of 520 watts. The compressor has no inverter, so it cycles on and off. There is no eco mode listed, but the 24-hour timer lets you limit running time to when the room is in use.
Controls and Smart Features
The digital control panel and included remote handle temperature, mode and the 3 cooling and fan speeds. The remote lets you adjust settings from anywhere in the room, which is handy in a bedroom.
The 24-hour timer lets you create a cooling schedule, and 2-way air deflection directs airflow where you want it. Auto Restart turns the unit back on after a power failure. There is no Wi-Fi or app control.
In practice, the combination of a remote and a timer covers most bedroom needs: you can start cooling before bed and set the unit to switch off after you fall asleep, without getting up.
Maintenance and Drainage
The slide-out washable filter is easy to remove and rinse, and a filter light reminder tells you when it needs attention. Regular cleaning keeps airflow steady and helps the unit cool efficiently through the season.
LG says the unit can be used for cooling, dehumidification or air circulation. The listing does not describe condensate drainage, so check the manual for how water is handled and for end-of-season storage.
