Best OverallA quiet, efficient window unit for a medium bedroom or living room, with app and voice control on top. It needs a double hung window within the listed width range, and its weight makes the install a careful job.
A U shaped inverter window air conditioner built to leave the window usable, with app, remote and voice control. Window fit is the main check, since the opening has set width and height limits.
A larger U shaped inverter window unit with app and voice control and a bracket in the box. The window opening needs a minimum height and a width in range, so measure first.
A quiet, smart window unit that installs below the sill so the window still opens and the view stays clear. It is heavy and has no inverter, so it suits a medium bedroom or living room where quiet and daylight matter most.
A quiet, app-connected window unit for a bedroom or small living room, with inverter control that eases power use. It is heavy to lift into the window, and the opening width needs measuring first.
A quiet inverter window air conditioner with app, voice and remote control, bundled with an air purifier. The listing gives no floor area rating, so match the cooling capacity to the room before ordering.
A small window unit for a bedroom or den with remote control, timer and auto restart. Its non-inverter compressor and the unreliable window opening figures are the points to check first.
A WiFi window air conditioner with app and voice control and a washable filter, suited to a room with a window inside its opening range. It runs without an inverter and is heavy to lift into place.
A straightforward window unit for a medium room that plugs into a regular outlet and restarts on its own after an outage. It is not an inverter model, so the compressor cycles on and off instead of slowing down.
A smart inverter window unit for one room, controlled by app or remote and shipped with its own support bracket. The listing never states a coverage area, so size the room from the BTU rating first.
Popular PickA small window air conditioner for bedrooms, with adjustable side panels and a washable filter. It is not inverter driven, and the unit is heavy for one person.
A smart, standard compressor window unit for medium to large rooms that wants app control without inverter features. It runs louder than inverter models.

A basic window air conditioner for a bedroom or small living room, with touch controls and a clean-filter light. It is a non-inverter unit with a short replacement warranty.
A quiet, smart window unit that cools in summer and adds efficient heat in spring and fall for a bedroom or office. Its heat pump is supplemental only, so it cannot replace a furnace in a cold winter.

These 3 window air conditioners are the most searched brands and models among the established products in this category (monthly searches for each brand and model); on a tie, the one with more owner ratings ranks first. Product data comes from public Amazon listings (updated 2 days ago). We do not test products ourselves.
LG, Frigidaire, Friedrich, Midea, GE lead this category among the 10 brands that passed our curation checks.
A listing appears only when it has a recorded price, a minimum customer rating, and enough ratings or monthly sales. Generic and unbranded listings are left out, while every real brand stays, including brands sold only on Amazon. The ones that pass are ordered by how many people search for that brand and model each month; review counts only break ties.
Window air conditioners come in conventional box designs and designs that straddle the sill or let the sash close into a channel in the unit. That changes how much of the window the unit occupies and how it attaches, so start with the window’s opening style and frame construction. A wall air conditioner is a separate category: do not assume a window unit can go into a wall sleeve, because its side vents may need outdoor clearance.
Measure the clear opening with the sash in the position required for installation, then compare it with the model’s full permitted width and height limits. Among the 43 products that list window opening minimum width, most fall between 19 and 28 inches, and 23 inches is typical. The minimum width filter is a starting point; a wider opening must also fall within the maximum width that the installation kit accommodates. Many units are intended for vertically sliding windows, so a casement or horizontally sliding window needs explicit compatibility in the manual. Sill depth, frame obstructions and exterior clearance can rule out a unit even when the opening dimensions work. Establish whether the specified support bracket, side panels and seals fit your frame and whether they are supplied or sold separately.
Next, use the manufacturer’s room-sizing guidance for your room’s dimensions, ceiling height, sun exposure and connection to adjoining spaces. Advertised coverage assumes particular conditions; strong sun and heat from cooking can change the cooling demand. Oversizing can produce short cooling cycles that leave the room clammy, so extra capacity is not a substitute for sizing guidance. For a bedroom, compare sound information at the operating setting you expect to use, since a quiet setting may reduce airflow. Some variable-speed compressors can reduce repeated starts and stops. Directional louvers also matter when the window sits beside a bed or desk: establish whether they can steer the cold air away from where you sit or sleep.
Before ordering, confirm the required voltage, plug configuration and circuit requirements against the available electrical supply; follow the manual’s restrictions on extension cords. The manual should also specify any installation slope and drainage provisions, including whether a drain fitting is required and supplied. Compare labeled energy efficiency and estimated annual energy use for appropriately sized models under the same stated conditions; actual consumption depends on operating hours, temperature settings and weather. Check how the filter comes out and whether it is washable or replaceable. Check the manual’s cleaning instructions and whether routine maintenance is practical with the unit installed.
