Ranked #3 in Best Window Air Conditioners

2 sources

The LG LW8017ERSM is the value standard for an 8,000 BTU window AC. It cools a 340 sq ft room fast, pulls more humidity out of the air than most rivals at about 2.2 pints per hour, and includes Wi-Fi, app control, and voice assistants that usually cost more. The compromise is noise: as a single-speed unit it runs loud on high. For the price, reviewers consistently rank it among the best window ACs you can buy.

Strengths
  • — Reviewed.com's best-value pick; strong cooling for the price
  • — Moves 220 CFM and removes about 2.2 pints of moisture per hour, among the best in class
  • — Wi-Fi with LG ThinQ app plus Alexa and Google Assistant voice control
Watch-outs
  • — Single-speed compressor is one of the louder units at high fan speed
  • — Only a 1-year warranty
  • — No inverter, so it cycles on and off rather than modulating

3 sourcesall derived$389as of Sep 6

The Windmill 8,300 BTU WhisperTech is the design-forward choice in this category. Its inverter compressor starts around 42 dB, its perforated matte-white face and auto-dimming display blend into a modern room, and the pre-assembled kit makes installation unusually painless. Reviewers from Tom's Guide to Bustle praise its quiet, stylish cooling. You pay a premium for the looks and the quiet, and in return you get efficient room-wide cooling up to 350 sq ft.

Strengths
  • — Quiet WhisperTech inverter starts around 42 dB; praised by Tom's Guide and Bustle
  • — Sleek, low-profile design with a perforated front and auto-dimming display that hides in a modern room
  • — Pre-assembled install kit makes setup genuinely fast with no heavy lifting
Watch-outs
  • — Priced at a premium versus mainstream 8,000 BTU units
  • — 8,300 BTU covers up to 350 sq ft, so not for large open spaces
  • — Smart features rely on the Windmill app rather than a major ecosystem hub

How they stack up

LG LW8017ERSM 8,000 BTU Smart Wi-Fi Window AC

The budget-friendly pick of the group: cheaper than the inverter-based Midea MAW08HV1CWT and the U-shaped Midea MAW08V1QWT, with comparable cooling. The trade-off is that, lacking an inverter, it runs louder than either Midea and the LG LW6023IVSM.

Windmill 8,300 BTU WhisperTech Inverter Window AC

The most stylish and easiest-to-install unit here, with quiet inverter operation that rivals the Midea MAW08V1QWT, though that U-shaped Midea still wins on outright lowest noise. It costs more than the LG LW8017ERSM and the LG LW6023IVSM, trading price for design and a no-fuss install.
