This LG Smart Window AC with Heating and Smart Controls Is Just $400 Right Now

Most window air conditioners follow a simple formula: cool the room, maybe add a fan setting, and leave it at that. The LG LW8023HRSM window air conditioner, currently on sale for $399.99 on StackSocial, takes a slightly more flexible approach. It still installs like a typical window unit, but it adds heating and smart controls, making daily use easier. For someone cooling a bedroom, small apartment living room, or home office, the main appeal here is convenience. You can control the unit with a remote, the onboard buttons, or the LG ThinQ app on your phone. If you already use Amazon Alexa or Google Assistant, you can also adjust the temperature with a voice command instead of getting up to press buttons.

The cooling capacity is 7,600 BTU, which LG recommends for rooms up to 330 square feet. In practical terms, that size works well for most bedrooms, studio apartments, or compact office spaces. It should bring the temperature down fairly quickly after a hot afternoon, especially if the room stays closed. This unit also includes 3,850 BTU of heating, which can be helpful during cooler months when you want a little warmth without turning on central heat. You can also switch between cool, heat, fan, and dehumidify modes, depending on what the room needs that day. Two cooling speeds and two fan speeds give you some control over how aggressively the unit runs. Airflow is adjustable in four directions, so you can angle the air away from your bed or couch.

LG lists the noise level at about 50–52 dB, so it produces a steady background hum, but not enough to drown out conversation or a TV. Rounding things out, there’s a 24-hour programmable timer that lets you schedule the AC to turn on before you get home or shut off overnight. You’ll also find an auto-restart function that restores your previous settings after a power outage, so you don’t have to reset everything. The main limitation is coverage—at this size, it’s built for smaller rooms, not large open living spaces. But if you want a window unit that cools reliably and gives you a few more ways to control it, this one fits the role without stepping into premium pricing.
