LG LW8017ERSM1 review

The LW8017ERSM1 is LG's current version of the long-running LW8017ERSM, an 8,000 BTU smart window unit rated for rooms up to 340 sq ft. Its strength is price: LG's US store lists it at $319, the lowest verified price on this list for a Wi-Fi unit from a major appliance brand. The LG ThinQ app adjusts temperature, changes modes and monitors energy use, and the unit works with Alexa and Google Assistant. LG lists an Energy Saver mode, 4-way air direction, auto restart after a power cut, a 24-hour timer and sleep mode, and a remote comes in the box. LG says it installs quickly in most windows. The trade-offs are clear in what LG does not list: there is no inverter and no published noise rating on the product page, and the standard box shape takes up the bottom of the window. If you need more capacity, the same page sells 10,000, 12,000 and 14,000 BTU sizes at $389, $489 and $579.
