The short answer
Best overall: the Midea U MAW08V1QWT — full app + Alexa/Google + scheduling on a true dual-inverter at 15 CEER and 42 dB for about $300, with 16,000+ owners at 4.5★. Bigger rooms: the 12K Midea U or the LG Dual Inverter LW1022IVSM. Keep the view: the GE Profile ClearView with SmartHQ, at 41 dB. Fifteen window units in our catalog now carry an app; ten have the full app-plus-voice-plus-scheduling stack. The matrix below shows exactly who has what — because “smart” on the box does not always mean voice, and it rarely means much on an inverter.
The feature matrix: who actually has what
Full stack — app + voice (Alexa/Google) + scheduling: Midea U 8K & 12K · LG LW1022IVSM · LG LW8022IVSM · LG LW1521ERSM (all ThinQ) · GE Profile ClearView 8K (SmartHQ) · Windmill AC · Friedrich Chill Premier (FriedrichGo) · Hisense 10K (ConnectLife) · TCL 8K inverter.
App + voice, no scheduling: Midea Smart MAW08HV1CWT · Windmill 10K · GE Profile ClearView 10K · LG LW1522IVSM 14K.
App only (no built-in voice): Frigidaire Inverter FHWW084WD1 — scheduling through the Frigidaire app, but no Alexa/Google.
Two things the matrix does not show and you should know: none of these units advertise Apple HomeKit or Matter, so a HomeKit-only household will run these through Alexa or Google or not at all; and the ecosystem name matters for multi-appliance homes — if you already run LG appliances on ThinQ or GE on SmartHQ, staying in that app is a real quality-of-life win.
The picks, by room
Best overall (~350 ft²): Midea U MAW08V1QWT — the rare unit that is best-in-class on smart features, efficiency (15 CEER), noise (42 dB) and price (~$300) at once. The U-shape closes the window sash onto it so the glass blocks compressor noise. Caveats from our data: earlier units were covered by a 2025 recall, so buy the current version, and the bracket install is more involved than a standard chassis.
Best mid-size (~450 ft²): LG Dual Inverter LW1022IVSM — ThinQ with Alexa/Google and scheduling, 10,000 BTU, 15.0 CEER, 44 dB, ~$429, 4.6★ across 2,800+ owners. Our overall window pick; the app is the polished LG one.
Best large room (~550 ft²): Midea U MAW12V1QWT — the U-shape scaled to 12,000 BTU while still idling at 42 dB, 15 CEER, ~$419, 4.5★ across 15,000+ owners.
Keep the view: GE Profile ClearView AHTT08BC — the below-the-sill saddle design preserves the window and runs at a remarkable 41 dB, with SmartHQ app + voice + scheduling, ~$399. Honest trade-off: it is fixed-speed at 11.4 CEER, so it costs more to run than the inverters above.
Efficiency king (~340 ft²): LG Dual Inverter LW8022IVSM — 15.2 CEER, the highest in our catalog, 44 dB, full ThinQ stack, ~$429. See how it stacks against the Dreo and the Windmill in Dreo vs LG and LG vs Windmill.
Where the smart features actually pay off
Three uses justify Wi-Fi on an AC. Pre-cooling: start the unit from your phone 20 minutes before you get home instead of running it all day or walking into a hot room. Scheduling and geofencing: the unit runs less when nobody is there — the one feature that measurably lowers a bill, and it matters most on fixed-speed units that otherwise blast at full power. Remote check: confirming the AC is off from the airport is worth more than it sounds. What Wi-Fi does not do is make a unit more efficient while it runs — that comes from the compressor and the CEER rating, which is why the app is a bigger deal on a budget fixed-speed unit than on an inverter. Our companion explainer, does Wi-Fi on an AC actually save money?, puts numbers on it.
The smart-plug question
A common workaround: put a dumb AC on a smart plug. It does not do what people hope. Cutting power to a running compressor and restoring it repeatedly stresses the compressor and can trip it, and most units do not resume their last mode after a power cut — so “turn on at 5pm” often just powers up a unit that then sits idle. A smart plug is fine as an energy monitor or an emergency kill switch; it is not a control method. If control is the goal, built-in Wi-Fi now costs nothing extra: the Midea U at ~$300 is cheaper than several non-smart units in our under-$300 guide.
Before you buy
Smart or not, size the room first — an oversized unit short-cycles and wastes the very efficiency you paid for. Sixty seconds with the BTU calculator settles it. Then use the matrix above to match the ecosystem to the one you already live in, and check the whole field in the best window ACs guide or the full comparison table.

Frequently asked questions
What is a smart window air conditioner?
A window AC with built-in Wi-Fi so you can control it from a phone app — set temperature, switch modes, and usually schedule it — and, on most models, by voice through Amazon Alexa or Google Assistant. The best ones add scheduling and geofencing so the unit runs less when nobody is home. It is the same cooling hardware as a regular window unit; the “smart” part is the control layer.
Which smart window AC is the best overall?
The Midea U MAW08V1QWT for most rooms: full app + Alexa/Google + scheduling, a true dual-inverter at 15 CEER, 42 dB, and about $300 with 16,000+ owner reviews at 4.5★. For a bigger room the 12K Midea U or the LG Dual Inverter LW1022IVSM (ThinQ app, 4.6★ across 2,800+ owners) are the picks. If preserving your window view matters most, the GE Profile ClearView saddle unit runs the SmartHQ app at a remarkable 41 dB.
Can I use a smart plug with a window air conditioner instead?
Not safely as a control method, and it will not do what you want. Cutting power to a running compressor and restoring it repeatedly stresses the compressor and can trip it, and most units do not resume their last mode after a power cut. A smart plug can tell you power draw and act as an emergency off; it cannot set temperature or modes. If control matters, buy a unit with Wi-Fi built in — the Midea U does it for about $300.
Does a smart window AC save money?
It can, in one specific way: by not running when nobody is there. Scheduling and geofencing prevent a unit from cooling an empty room, which matters most on fixed-speed units that otherwise blast at full power. On an inverter, most of the saving comes from the variable-speed compressor itself, and the app is mostly convenience. Our companion explainer works through the actual numbers.
Do smart window ACs work with Alexa and Google?
Most do — LG (ThinQ), Midea, GE Profile (SmartHQ), Windmill, Friedrich (FriedrichGo) and Hisense (ConnectLife) all support Alexa and Google Assistant on the models we track. The Frigidaire FHWW084WD1 is the exception: app scheduling only, no built-in voice. We do not list Apple HomeKit or Matter support for any of these units, because none of them advertise it.
