The LG LW8024RD 8,000 BTU Window Air Conditioner is a remote-controlled unit for medium rooms up to 350 square feet, about 14′ x 25′. It sits in one of the most popular sizes of conventional window air conditioners, aimed at bedrooms, living rooms and home offices.
It covers the core comfort features: 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 decision is whether its weight and conventional compressor suit your needs. We evaluated it based on the manufacturer’s specifications.
Our Verdict
This LG is a dependable all-rounder for a medium room. Its strongest points are the remote and electronic controls, 3 cooling and fan speeds plus Auto Cool, a 24-hour timer, 4-way air deflection and Auto Restart. The specifications list a noise level of 54 dB, and it holds 4.3 stars from 407 ratings.
The trade-offs are weight and features. At 57 pounds it is heavy for an 8,000 BTU unit, and it has no inverter, Wi-Fi or eco mode. If you want straightforward, remote-controlled cooling for a bedroom or living room up to 350 square feet, it is a solid choice.

Cooling Capacity and Room Size
LG rates the LW8024RD at 8,000 BTU for rooms up to 350 square feet, about 14′ x 25′, and suggests bedrooms and living rooms. That covers a large bedroom, a home office or a compact living room.
As always, 350 square feet is the upper limit. A room near that size with large sunny windows or high ceilings will need the unit to run longer. For a typical bedroom, it has some capacity to spare, which helps it bring the room down to temperature quickly.
This size is also a good choice for a bedroom that doubles as a work space. Computers and lighting add heat during the day, and the extra capacity over a 6,000 BTU unit keeps the room comfortable without being oversized at night.
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 8,000 BTU, it lines up with rooms of about 300 to 350 square feet, so LG’s coverage claim sits at the top of the chart’s range for this capacity.
Installation and Fit
The listed window opening is 22 to 36 inches wide with a minimum height of 13 inches. The easy window installation kit includes window curtain panels, and the remote and batteries come in the box.
The cabinet measures 19.38 inches deep, 19.57 inches wide and 12.33 inches tall, and weighs 57 pounds. That is a two-person job: one person to hold the unit and one to lower the sash and fasten it. Follow the manual and use the supplied hardware so it is fully secured. It plugs into a standard 115V outlet.
Noise, Energy Use and Efficiency
LG markets low-noise performance, and the specifications list 54 dB. That is reasonable for a bedroom, especially on the lowest fan speed, though sound levels depend on how well the curtain panels seal the window.
The listing gives an efficiency figure of 11.4, labeled as SEER, and a power draw of 660 watts. The scroll compressor has no inverter, so it cycles on and off. There is no eco mode, but Auto Cool and the 24-hour timer help avoid unnecessary running.
Controls and Smart Features
Electronic controls and the included remote handle temperature, mode and fan speed. The 3 cooling and fan speeds and Auto Cool mode let you tailor comfort, with Auto Cool adjusting the fan to hold your set temperature.
The 24-hour timer lets you create a cooling schedule, and 4-way air deflection directs airflow up, down, left or right. Auto Restart powers the unit back on after an outage without you resetting it. There is no Wi-Fi or app control.
For most bedrooms, the remote and timer cover what smart features would otherwise do. You can set the unit to start an hour before bed and switch off in the early morning, and the 4-way deflection lets you keep airflow off the bed if you prefer indirect cooling.
Maintenance and Drainage
The removable, washable filter makes cleaning easy. Rinse it regularly during the cooling season to keep airflow strong and efficiency steady. A dirty filter makes the unit work harder for the same cooling and can shorten the life of the compressor.
LG notes the unit supports cooling, dehumidification and air circulation. The listing does not describe condensate drainage, so check the manual for how water is handled and for seasonal storage steps.
Pros and Cons
| Pros | Cons |

Who Should Buy It

| Buyers who want a remote and timer | Smart home users who want app control |

| Buyers who prefer simple, proven controls | Casement or sliding window owners |
Final Verdict
The LG LW8024RD 8,000 BTU Window Air Conditioner is a practical, well-equipped unit for a medium room. A remote, 24-hour timer, 3 fan speeds with Auto Cool, 4-way air deflection and Auto Restart cover the features most people use daily. The compromises are a 57 pound weight and the lack of an inverter or smart controls.
