LG is one of the best-known names in window air conditioners, and it is especially associated with its Dual Inverter technology, which aims to cool quietly while using less energy than a traditional unit. If you have searched for an LG inverter air conditioner, you have probably seen the phrase “Dual Inverter” again and again without a clear explanation of what it actually does for you. This guide explains it in plain terms and helps you match a unit to your room.
The four models below differ mainly in cooling power and compressor type: two are Dual Inverter units at 8,500 and 10,000 BTU with WiFi and voice control, while the 14,000 BTU and 5,000 BTU models use conventional, non-inverter compressors and simpler remote controls.

LG 8,500 BTU Window AC
Best for: Quiet bedrooms up to 350 sq ft
Pros
- Dual Inverter compressor
- 44 dB in sleep mode
- WiFi, Alexa and Hey Google
- 4 cooling and fan speeds
Cons
- Listing also mentions 6,000 BTU
The LG 8,500 BTU Window AC (model LW8024IVSM) is the smallest Dual Inverter unit in this group. The listing says it cools rooms up to 350 square feet, about 14 by 25 feet, and runs as low as 44 dB in sleep mode, which LG compares to a library. It uses R-32 refrigerant, a washable filter with a filter reminder light, and has a dehumidifier function.
What does Dual Inverter mean? A standard air conditioner’s compressor, the part that does the cooling work, switches fully on and fully off again and again. An inverter compressor instead speeds up and slows down smoothly to hold your chosen temperature, so it runs more quietly and wastes less energy. LG says this model is up to 35% more energy efficient than the Energy Star certification requirement. It also offers four cooling and fan speeds with Auto Cool, a 24-hour timer, an LCD remote, and control through the LG ThinQ app, Amazon Alexa and Hey Google.
One thing to know: one line in the listing mentions “this 6,000 BTU Air Conditioner,” while the title and specifications say 8,500 BTU. We have used 8,500 BTU as the listed cooling power, but confirm on the product page before buying. This model suits bedrooms and medium rooms where quiet sleep matters; for a bigger living space, the 10,000 BTU model is the step up.

LG 10000 BTU Window Air Conditioners
Best for: Living rooms up to 450 sq ft
Pros
- Dual Inverter compressor
- 44 dB sleep mode
- ThinQ app and voice control
- EZ Mount kit included
Cons
- Fits 22 to 36 inch windows only
The LG 10000 BTU Window Air Conditioners listing covers the LW1022FVSM, a Dual Inverter, Energy Star unit that cools up to 450 square feet. It shares the 44 dB sleep-mode noise level and R-32 refrigerant with the 8,500 BTU model, and the listing credits LG’s BLDC motor and Dual Inverter compressor for the quiet running. A BLDC motor is a brushless motor, a design that tends to run smoothly with less noise.
It connects to WiFi for the LG ThinQ app and works with Google Assistant and Amazon Alexa. The controls include an LED display, up and down temperature buttons and a remote. It has a fixed chassis, meaning the unit slides into the window as one piece, and it fits double-hung windows from 22 to 36 inches wide and 13 inches high with the included EZ Mount installation kit. The slide-out washable filter should be cleaned every 30 days, and there is a dust filter, filter reminder and dehumidifier function.
This is the best all-round pick for a living room, open bedroom or small apartment that needs more reach than the 8,500 BTU unit. If your room is much larger than 450 square feet, the 14,000 BTU model has more power, though without the inverter.
LG 14,000 Window Air Conditioner for Big Rooms
LG
LG 14,000 Window Air Conditioner, 115V, 700 Sq.Ft. (25' x 28' Room Size), Quiet Operation, Electronic Control with Remote, 3 Cooling & Fan Speeds, Auto Restart, 14000 BTU, White
Price and specifications are read from the Amazon product page and can change.
LG 14,000 Window Air Conditioner
Best for: Large open rooms needing raw power
Pros
- 14,000 BTU cooling
- Auto Restart after outages
- 24-hour timer
- 4-way air deflection
Cons
- No inverter
- 59 dB, loudest here
The LG 14,000 Window Air Conditioner (LW1424RD) is the most powerful unit here, but it is important to be clear: its specifications list “No Inverter,” so it does not offer the Dual Inverter benefits covered above. Its listed noise level is 59 dB, the highest in this lineup.
The listing is inconsistent about room size. The title says 700 square feet (25 by 28 feet), while the feature list and description say up to 800 square feet (20 by 40 feet). Plan around the lower figure to be safe. It offers three cooling and fan speeds with Auto Cool, electronic controls with a remote, a 24-hour on/off timer, 4-way air deflection to direct airflow, a dehumidifier function, and a slide-out washable filter with a Check Filter alert. Auto Restart turns the unit back on after a power failure. The listed dimensions are 23 5/8 inches wide, 15 inches high and 22 1/5 inches deep.
This suits large family rooms, garages converted into living space, and open-plan areas where cooling power matters more than whisper-quiet running. The listing does not mention WiFi or voice control. If you want a large-capacity unit you can move between rooms instead, our 14,000 BTU portable air conditioner guide covers that format.

LG 5000 BTU Window Air Conditioner
Best for: Small bedrooms and home offices
Pros
- Compact 150 sq ft unit
- Remote and LCD panel
- Energy Save function
Cons
- No inverter
- Only two fan speeds
The LG 5000 BTU Window Air Conditioner (LW5025R) is a compact unit for rooms up to 150 square feet. Like the 14,000 BTU model, it lists “No Inverter” and uses a rotary compressor. Its listed noise level is 50 dB, quieter than the 14,000 BTU model but louder than the two Dual Inverter units.
It has an LCD display, a simple control panel with up and down temperature adjustment, and a full remote. There are two cooling modes, two fan speeds and an Energy Save function, plus R-32 refrigerant and a washable dust filter. It fits double-hung windows from 21 to 35 inches wide and 12 inches high with the included EZ Mount kit, and the slide-out filter should be cleaned every 30 days.
This is a good fit for a small bedroom, dorm or home office, or as a first air conditioner for someone new to window units. Buyers who want app control or the quieter inverter design should step up to the 8,500 BTU model.
How to Choose the Right LG Inverter Window Air Conditioner
Start with room size. BTU, short for British thermal unit, measures how much heat an air conditioner can remove. Measure your room’s length and width, multiply them for square feet, and compare: 150 square feet for the 5,000 BTU unit, 350 for the 8,500, 450 for the 10,000, and 700 to 800 for the 14,000. Buying too small leaves the room warm; too large can cool unevenly and feel clammy.
Next, decide whether Dual Inverter matters to you. Only the 8,500 BTU and 10,000 BTU models here have it. If you will run the unit overnight in a bedroom, the 44 dB sleep mode and energy savings make these the stronger picks. For comparison with other inverter window designs, see our guide to another popular inverter window air conditioner.
Then check your window. The 10,000 BTU unit fits windows 22 to 36 inches wide, and the 5,000 BTU unit fits 21 to 35 inches. The other two listings do not specify a window range, so measure against the listed dimensions.
Finally, think about controls. The two Dual Inverter units offer WiFi, the ThinQ app and voice control. The 14,000 and 5,000 BTU models rely on a remote and the control panel.
FAQ
What is an LG Dual Inverter air conditioner?
It uses a compressor that changes speed smoothly instead of switching fully on and off. LG says this makes its Dual Inverter units quieter and up to 35% more energy efficient than the Energy Star requirement.
Which LG models in this list are inverter units?
The 8,500 BTU and 10,000 BTU models. The 14,000 BTU and 5,000 BTU listings both state no inverter.
Can I control these air conditioners with my phone?
The 8,500 BTU and 10,000 BTU units work with the LG ThinQ app, Alexa and Google voice commands. The other two listings do not mention WiFi.

The two Dual Inverter models, at a listed 44 dB in sleep mode. The 5,000 BTU unit lists 50 dB and the 14,000 BTU unit lists 59 dB.
Do these units remove humidity?
The 8,500, 10,000 and 14,000 BTU listings name a dehumidifier function. The 5,000 BTU listing mentions keeping “your dehumidifier working efficiently” but does not list it as a feature, so check before relying on it.
Is a window unit or a portable unit better for a beginner?
Window units usually cool more efficiently because the hot parts sit outside. Portable units are easier to move. Our portable air conditioner guide explains that option.
