LG LW6023IVSM 6,000 BTU Dual Inverter Window AC

4.4

$399as of Jun 7

The LG LW6023IVSM is the efficiency champion for small rooms. Its Dual Inverter compressor delivers a 15.5 CEER, far above the federal minimum, and Consumer Reports named it the best small-room window AC of 2026 after it beat the runner-up by more than 11%.

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

4.5

$319as of Jun 7

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

How they stack up

LG LW6023IVSM 6,000 BTU Dual Inverter Window AC

The most efficient and the smallest-capacity unit here, ideal where the 8,000 BTU LG LW8017ERSM and the Midea MAW08HV1CWT would be overkill. It is quieter than the LG LW8017ERSM thanks to its Dual Inverter, though the U-shaped Midea MAW08V1QWT is quieter still.

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.
