Who should buy it?

A good fit if you…

  • The LG LW8017ERSM1 is right if: you want 340 sq ft of reliable cooling at the lowest price in this category, you're comfortable with a standard, moderately loud
  • Consider alternatives if: quiet operation is the top priority (Midea U-Shaped), you want the lowest visual footprint in the window (GE Profile ClearView), or yo

What You Are Buying

The LG LW8017ERSM1 is an 8,000 BTU window air conditioner rated to cool up to 340 sq ft.

It uses a standard fixed-speed compressor rather than an inverter, paired with 3 cooling and 3 fan speeds and a mechanical-plus-digital control panel.

LG ThinQ Wi-Fi connectivity is included for remote app control, Alexa, and Google Assistant.

Performance

Cooling speed: Owner reports across multiple retailers describe a 340 sq ft room becoming noticeably cooler within roughly 15 minutes on the highest cooling and fan setting, in line with what an 8,000 BTU unit should deliver at its rated coverage.

Noise: No published low-noise dB figure is available for this model, unlike the Midea U-Shaped (32 dBA) or GE Profile ClearView (41 dB).

It uses a standard fixed-speed compressor, which cycles fully on and off rather than holding a steady low output, producing a noticeable startup burst each time it kicks back in.

App reliability: The LG ThinQ app requires a 2.4GHz Wi-Fi connection and an LG account.

What It Does Well

The price-to-coverage ratio is the strongest argument for this unit.

Auto restart is a small but real convenience: after a power outage or brief power blip, common during summer storms, the unit resumes its last setting automatically instead of requiring a manual restart.

What Falls Short

No inverter compressor means more noise and less efficiency over a long cooling season compared to the Midea U-Shaped or Frigidaire FHWW085WE1, both of which use inverter technology at a similar or only slightly higher price.

No U-shaped or flex-depth frame means it sits fully inside the window opening rather than allowing the sash to lock down over it, a security consideration on ground-floor installations.

Who Should Buy It

The LG LW8017ERSM1 is right if: you want 340 sq ft of reliable cooling at the lowest price in this category, you're comfortable with a standard, moderately louder compressor, and you want Wi-Fi app control without paying an inverter premium.

Consider alternatives if: quiet operation is the top priority (Midea U-Shaped), you want the lowest visual footprint in the window (GE Profile ClearView), or you need directional airflow across a wide room (Frigidaire FHWW085WE1).

Answers

Frequently asked questions

Is the LG LW8017ERSM1 loud?

It has no published low-noise dB rating, unlike the Midea U-Shaped or GE Profile ClearView. Owner reports describe it as comparable to other fixed-speed window units, noticeably louder on high cooling than an inverter compressor unit, but not unusually loud for the category. It's not the pick if quiet operation is the top priority.

Does the LG LW8017ERSM1 need a stable Wi-Fi connection to work?

The compressor, cooling, and fan controls all work through the physical panel independent of Wi-Fi. The LG ThinQ app adds remote start, scheduling, and status monitoring, but a dropped Wi-Fi connection only disables the app features, not basic operation from the unit itself.

How big of a room can the LG LW8017ERSM1 actually cool?

LG rates it for up to 340 sq ft, which fits most bedrooms and smaller living rooms. In an open floor plan or a room with high ceilings, effective coverage will run smaller than the rated figure, similar to any window AC's rating being based on a standard 8-foot ceiling and a closed room.

Does the LG LW8017ERSM1 have a dehumidify-only mode?

Yes, most LG window units in this line include a dry mode that runs the compressor and fan at a slower pace primarily to remove humidity rather than aggressively lower temperature, useful on humid but not especially hot days.
