It delivers 24,500 BTU of cooling power and covers areas up to 1560 square feet, making it suitable for living rooms or open-plan apartments.

What stands out
- 24,500 BTU cooling capacity for large rooms up to 1560 sq ft

- Dehumidification rate of 1.8 pints per hour
Who it fits
Good fit for
You should buy this unit if you need to cool a large room, such as a master bedroom or living area, that exceeds 1000 square feet. The 24,500 BTU output handles significant heat loads. It suits tech users who want to adjust settings from their phone or via voice commands. The 230/208V requirement fits standard US home electrical outlets. If you value quiet nights, the 50 dB low mode is a strong benefit for bedrooms.
Who should skip it
Skip this model if you live in a smaller apartment or studio. The 24,500 BTU capacity is overkill for spaces under 800 square feet, which can lead to short cycling and inefficient dehumidification. It is also not suitable for rooms requiring 115V power, as this unit needs 230V. If you prefer a compact, lightweight unit for easy window installation, the 132-pound weight and 26-inch width may be too bulky for your setup. Look for a lower BTU model instead.
Verdict: This LG unit offers robust cooling and smart features for large spaces. It is a solid choice for big rooms with standard 230V outlets.
Key specs for this unit
Cooling Capacity: 24,500 BTU
This rating indicates the unit’s ability to remove heat from your space. A higher BTU number means faster cooling for larger volumes of air. You need this power level to effectively chill a room up to 1560 square feet. If you are comparing portable air conditioners, ensure the BTU matches your room size to avoid underperformance or excessive energy use.
Coverage Area: 1560 sq ft
This figure tells you the maximum floor area the unit can cool efficiently. It is designed for large living rooms, open-plan apartments, or multiple small rooms on the same floor. When shopping, compare this against your room dimensions. If your space exceeds this limit, the unit will struggle to maintain a comfortable temperature, requiring a more powerful model.
Noise Level: 50 dB
This decibel rating measures how loud the unit runs, specifically in low mode. At 50 dB, it is comparable to a normal conversation level, which helps eliminate unnecessary background noise. This makes it suitable for bedrooms or offices where quiet operation is important. You should check this spec when comparing other units to ensure they will not disturb your sleep or work.
Voltage: 230/208V
This specifies the electrical requirement for the unit. It needs a dedicated 230 or 208-volt circuit, which is different from standard 110-volt household outlets. You must verify that your home has the correct wiring and outlet type before installation. Using the wrong voltage can damage the unit or create safety hazards, so this is a critical check when comparing window air conditioners.
Control Type: Digital panel, remote, Wi-Fi app, voice
This listing shows the various ways you can operate the unit. You can use the digital panel, a physical remote, a smartphone app via Wi-Fi, or voice commands with assistants like Alexa or Google. This flexibility allows you to adjust settings from anywhere in the room or remotely. When comparing features, look for app support if you want smart home integration.
Design and build overview
The LG 24,500 BTU Smart Window Air Conditioner is a substantial unit. According to the listing, it weighs 132 pounds. This mass helps stabilize the chassis but requires two people for safe installation. The exterior finish is white, a standard choice that blends with most window frames and interior walls. You should verify your window opening dimensions before mounting, as the unit measures 26 inches wide, 17.7 inches high, and 28.1 inches long. These dimensions dictate the minimum sash width needed for a secure fit.
Control layout combines physical and digital elements. A digital control panel sits on the unit for local adjustments. You also receive a remote control for convenience from across the room. The listing notes Wi-Fi app support via LG ThinQ, allowing you to adjust settings from your phone. Voice control compatibility with Amazon Alexa and Hey Google adds another layer of remote access. This multi-layered control scheme means you can manage the unit without getting up.
The design prioritizes functionality over aesthetic flair. The heavy build ensures durability during operation. The inclusion of a remote and app support reduces the need to interact with the physical panel frequently. You can set timers or change modes without leaving your seat. The straightforward design means fewer decorative parts to clean, keeping maintenance simple. The white finish resists visible dirt better than darker colors, maintaining a clean look with minimal effort.
Setup and daily operation guide
The listing states that a remote and installation kit are included. You will need to mount the unit in a window frame using the provided hardware. The physical dimensions are 26 inches wide, 17.7 inches high, and 28.1 inches deep. The unit weighs 132 pounds, so you should have help during installation to ensure the chassis is secure and stable. Once mounted, you can control the device through four methods: a digital panel on the unit, the included remote, Wi-Fi via the LG ThinQ app, or voice commands through Amazon Alexa and Hey Google. The app allows you to adjust modes and temperature from anywhere. For daily use, you can choose from three cooling speeds and three fan speeds. The unit also offers dehumidification, removing up to 1.8 pints of moisture per hour. A 24-hour timer lets you schedule on and off cycles. A filter check reminder light alerts you when maintenance is needed. If power is restored after an outage, the auto restart feature returns the unit to its previous settings. Noise levels drop to 50 dB in low mode, which is suitable for bedrooms or offices where quiet operation is important. The 230/208V voltage rating means you must verify your outlet compatibility before pl it in.
Verify electrical and fit before buying
Before you finalize your purchase, verify your electrical infrastructure. This unit requires a 230/208V circuit. Standard household outlets provide 120V, so you must confirm you have the correct dedicated line to prevent tripping breakers or damaging the compressor. Check your window frame dimensions against the 26-inch width and 28.1-inch depth to ensure a secure fit. The listing includes a remote and installation kit, but you may need additional sealing materials for irregular gaps. Regular maintenance involves cleaning the filter, indicated by the reminder light, to sustain the 1.8 pints per hour dehumidification rate. This high-capacity model sits above standard portable options in power but demands more structural support. It suits large, open living areas or apartments where central air is insufficient. Ensure your space is properly insulated to maximize the 1560 square foot coverage. If you require precise humidity control in smaller rooms, a dedicated dehumidifier might be more efficient alongside this cooling unit.
Check before you buy
- Confirm you have a 230/208V dedicated circuit available.
- Measure window width and depth against 26 by 28.1 inches.
- Check if you need extra sealing materials for gaps.
- Plan for regular filter cleaning to maintain dehumidification.
