The best 12 000 BTU window air conditioner for most rooms is the LG 12,000 BTU (LW1216ER). It cools up to 550 sq ft, drops to a 53 dB low setting, and keeps the controls simple with a remote and a 24-hour timer.
If quiet matters more than price, the Midea 12 is the better fit at 32 dBA. For smart control and an inverter compressor in one unit, the DELLA 12000 BTU is the value pick.

How these 12,000 BTU window units were compared
We ranked these units by cooling coverage, running noise, control options, efficiency and how well each fits a typical window frame. Our score weighs specs, features and buyer feedback against what you're shopping for.
Every pick here delivers 12,000 BTU, but the units split into two camps. Standard models use a fixed-speed compressor.
Inverter models such as the Della, Midea and ROVSUN vary compressor speed to hold a temperature more steadily and cut energy use. The rest of the field adds features on top of a standard compressor: WiFi, a better louver design, a timer, or a lower noise floor.
A unit that carries all of those at once is rare, which is why the LG wins on balance rather than on any single spec. A 12,000 BTU unit also means real weight, from about 57 lb to about 73 lb, so measure your window opening and plan the lift before you buy.
Depth matters too: the deepest units are around 22 in, and the Midea's U-shape takes up less of the sill inside your room. For the wider decision process, our guide on how to choose a window air conditioner covers window types, electrical checks and sizing.
| Product | Best for | Cooling power | Room coverage | Noise | Our score |

The best 12 000 BTU window air conditioners for each job
The LG is the strongest all-rounder, but each of the others wins when one need matters most. Pick by the room you're cooling and the controls you'll actually use.
LG 12: Best overall
- Cools up to 550 sq ft
- 53 dB low setting
- 3 cooling and fan speeds
- 24-hour timer
- 4-way air direction
The LG balances quiet running, simple controls and wide coverage better than any other unit here. It is the easy default for a bedroom or living room up to 550 sq ft.
Pros
- Quiet 53 dB low setting
- Washable slide-out filter
- Auto restart after a power cut
Cons
- No smart app or voice control
- No inverter compressor
The LG suits a bedroom or living room up to 550 sq ft where you want good cooling without a complicated setup. Its 53 dB low setting is the quietest of the standard-compressor units here, so it won't dominate a room at night.
Three cooling and fan speeds plus Auto Cool let you tune airflow to the weather. The four-way air direction sends cool air across a sofa or toward the far side of a room, and the slide-out washable filter is easy to rinse.
The filter light reminder takes the guesswork out of when to clean it. The 24-hour on/off timer builds a cooling schedule, and auto restart brings the unit back after a power cut.
A remote covers every setting from across the room. At 22.2 in deep and 23.6 in wide it needs a fairly generous sill.
The trade-off is simple: no app, no voice control, no inverter compressor. For straightforward, reliable cooling at a fair price, that's a short list of things to give up.
DELLA 12000 BTU Energy Saving Window Air: Best smart value
- Cools up to 550 sq ft
- WiFi, Alexa and Google Assistant
- 10.9 CEER
- 56 dB
- Dehumidifier mode
Della packs WiFi, voice control and an inverter compressor into a 550 sq ft unit. It is the pick when you want to start cooling from your phone before you get home.
Pros
- WiFi and Alexa control
- 10.9 CEER rating
- Dehumidifier dry mode
Cons
- 56 dB is louder than the top pick
- WiFi works on 2.4 GHz only
Della is the smart pick for a buyer who wants to start cooling before they get home. WiFi, Alexa and Google Assistant control sit on top of a 550 sq ft inverter unit, so you can set a temperature from the office or by voice in the kitchen.
The Della+ app adds GEO Location control as well. The inverter compressor and 10.9 CEER rating point to lower running costs than a fixed-speed unit.
A dry mode pulls moisture from the air in muggy weather, and the LED panel plus remote keep everyday use simple. Sleep mode and a 61 to 88 F range cover most comfort needs.
Its 56 dB low setting is louder than the LG and far louder than the Midea. The WiFi radio runs on the 2.4 GHz band only, which matters if your router separates bands.
At 63.7 lb it's lighter than several units here. If smart control and an inverter matter more than the last few decibels, this is the best value in the group.
For a silent bedroom, look at the Midea instead.
Midea 12: Best for quiet bedrooms
- U-shaped design
- 32 dBA low
- Inverter compressor
- Energy Star certified
- App and voice control
The U-shaped Midea blocks outside noise and runs as low as 32 dBA. It is the strongest choice for a light sleeper who wants the window to still open.
Pros
- 32 dBA low setting
- Window opens with the unit in place
- Energy Star certified
Cons
- U-shape bracket needs 22 to 36 in window width
- Higher price than standard units
Midea is the pick for a light sleeper. The U-shaped frame sits in the window so the window closes around it, blocking outside noise, and the inverter system runs as low as 32 dBA, nine times quieter than a traditional unit by Midea's count.
The U-shape also keeps more of your view and lets the window open while the unit is installed. An anti-theft mechanism locks the window when it's shut.
SmartHome app, Alexa and Google Assistant control come built in, and the touch panel works without either. Midea says the unit was the first window AC to earn Energy Star certification, with more than 37% energy savings claimed against traditional units.
The bracket fits single-hung or double-hung windows 22 to 36 in wide with at least 13.75 in of height. At 56.9 lb it's the lightest unit here.
That bracket is the trade-off: it needs a wider opening than some here, and the unit costs more. For quiet and efficiency in a bedroom, it's worth it.
BLACK+DECKER Window Air Conditioner 12000 BTU: Best for straightforward installs
- Cools up to 550 sq ft
- Full-function remote
- Sleep and energy saver modes
- R32 refrigerant
- Fits 23 to 36 in windows
A plain, well-rounded window unit with a full remote and easy accordion-panel fitting. It suits a buyer who wants simple cooling without paying for smart features.
Pros
- Fits windows from 23 to 36 in wide
- Sleep and energy saver modes
- R32 refrigerant
Cons
- No app or voice control
- No inverter compressor
The BLACK+DECKER BD12WT6 suits a buyer who wants a solid, familiar unit without smart extras. Accordion side panels fit double-hung windows from 23 to 36 in wide and as low as 15.5 in, so most standard openings work.
A 70 in cord gives some slack at the outlet. A full-function remote covers sleep mode, energy saver and a 24-hour timer.
Four fan levels (auto, low, medium and high) let you step airflow down as the room cools. The thermostat runs from 62 to 86 F.
BLACK+DECKER says the R32 refrigerant carries zero impact on the ozone layer and helps keep energy use down. The washable filter and included mounting kit keep maintenance and setup basic, and the unit weighs 66.8 lb.
It doesn't offer app control or an inverter compressor, and it gives up the LG's quiet floor. For a straightforward install and simple cooling in a 550 sq ft room, those are easy things to live without.
Vtronix Classic America Classic America 12000 BTU Window: Best for Alexa homes
- Cools up to 550 sq ft
- App, remote and Alexa control
- Eco mode and timer
- Install kit included
- 1-year warranty
This unit adds app and Alexa control plus a 1-year warranty to a standard 550 sq ft frame. It fits buyers already running their home through smart speakers.
Pros
- Works with Alexa and Google Assistant
- Eco mode and programmable timer
- 1-year warranty
Cons
- No inverter compressor
- 56 dB, not the quietest here
Vtronix Classic America suits a household already running on smart speakers. Alexa and Google Assistant control join an app and remote, so you can adjust cooling hands-free or from another room.
The touch panel covers the same settings up close. It covers 550 sq ft with eco mode and a programmable timer to trim power use.
The install kit, adjustable hardware and side panels ship in the box for double-hung windows. Low power start helps avoid tripping a shared circuit, and a 1-year warranty backs the unit.
The compact 22 x 20 x 16 in frame is built to fit easily in a standard opening, and at 64 lb it sits mid-pack for weight. It runs on a standard compressor and reaches 56 dB, so it isn't the quietest or the most efficient here.
If voice control is your priority and you're happy with a fixed-speed compressor, this unit does the job.
ROVSUN 12000 BTU Inverter Window Air Conditioner: Best for low running costs
- Cools up to 520 sq ft
- Inverter compressor
- 15.0 CEER
- 42 dBA sleep mode
- Pre-assembled side panels
ROVSUN pairs a 15.0 CEER inverter with a 42 dBA sleep mode and a faster install. It covers slightly less floor area than the 550 sq ft leaders.
Pros
- 15.0 CEER inverter efficiency
- 42 dBA in sleep mode
- Ships with side panels fitted
Cons
- Covers 520 sq ft, less than the top picks
- Smaller brand support network
ROVSUN is the efficiency pick. A 15.0 CEER inverter compressor gives about 35% more energy savings than traditional units, and sleep mode drops noise to 42 dBA.
That combination suits a room used every evening. The side panels arrive pre-assembled, which ROVSUN says saves about 30% of install time against a standard window unit.
Four-way swing spreads air around the room, and the LED panel plus remote cover sleep, eco, auto and fan modes. The thermostat runs 61 to 88 F.
It covers 520 sq ft, slightly less than the 550 sq ft leaders, so check your room size before choosing it. The window width range is 25 to 36 in with a 14.5 in minimum height.
At 58.6 lb it's among the lighter units here. For long summer use in a medium room, the lower running cost can offset the smaller coverage.
If your room sits right at 550 sq ft, the LG or Della is the safer capacity match.
BLACK+DECKER Window Air Conditioner 12: Best for set-and-forget schedules
- Cools up to 550 sq ft
- 10.9 CEER
- Sleep and energy saver modes
- Timer and clock
- Auto restart
A timer and clock make this BLACK+DECKER easy to set around a daily routine. It also brings a 10.9 CEER rating to a 550 sq ft room.
Pros
- Timer and clock for scheduled cooling
- 10.9 CEER
- Auto restart
Cons
- No smart app or voice control
- Older design than the top picks
This BLACK+DECKER BWAC12WTB suits a buyer who wants cooling tied to a daily routine. A timer and clock let you set the unit to start before you get home and stop after you go to bed, with sleep and energy saver modes to trim use overnight.
It covers 550 sq ft at a 10.9 CEER rating. Three cooling and fan speeds plus an auto thermostat adjust to changing weather, and a full-function remote plus digital display handle the settings.
The thermostat range is 61 to 88 F, and a fan-only function moves air without cooling. Auto restart brings it back after an outage, and the removable washable filter is easy to clean.
The install kit fits windows 26 to 36 in wide and as low as 16 in. At 63.7 lb it's light enough for two people to manage.
It lacks app and voice control, and the design is older than the leaders here. Pick it when scheduled cooling matters more than smart features.
Amana 12: Best for wide air coverage
- Cools up to 550 sq ft
- 8-way air louvers
- 2.6 pints per hour dehumidifying
- Eco and sleep modes
- Auto restart
Amana's 8-way louvers push air into more corners than a standard vent. It suits an L-shaped room or a long living area where one vent direction leaves a warm spot.
Pros
- 8-way directional louvers
- Dehumidifies 2.6 pints per hour
- Clean filter alert
Cons
- No inverter compressor
- No smart features
Amana suits a room where one vent direction leaves a warm corner. 8-way directional louvers give more control over where the air lands, which helps in an L-shaped living area or a long bedroom.
It covers 550 sq ft and dehumidifies 2.6 pints per hour, useful in humid weather. Eco mode, sleep mode and a 24-hour programmable timer keep energy use in check, and a remote covers every setting.
Sleep mode gradually raises the temperature overnight. A Clean Alert tells you when to wash or replace the filter.
The window kit fits openings with at least 16 in of height, and the unit measures 21.5 in wide and 19.8 in deep. It runs on a standard compressor with no smart control, so it trails the leaders on efficiency and convenience.
Choose it when air direction is the deciding factor.
Whirlpool 12: Best for apartment cooling
- Cools up to 550 sq ft
- 8-way air louvers
- 24-hour timer
- Eco and sleep modes
- Remote included
Whirlpool offers wide air direction and a simple timer at the lowest score in this group. It is a fine basic unit for a rental or a room where smart features go unused.
Pros
- 8-way directional louvers
- Programmable 24-hour timer
- Filter clean alert
Cons
- No inverter compressor
- No WiFi or app control
Whirlpool is the basic pick for a rental, a dorm or a room where smart features would go unused. It covers 550 sq ft with 8-way directional louvers and a programmable 24-hour timer.
Three cooling speeds, eco mode and sleep mode handle everyday comfort. A remote and digital display make settings easy, and a Clean Alert flags filter cleaning.
Like the Amana, it dehumidifies about 2.6 pints per hour. The install kit fits windows with at least 16 in of height.
At 72.8 lb it's the heaviest unit here, so plan the lift carefully and measure the sill before you commit. It has no inverter compressor and no app or voice control, which is why it scores lowest in this group.
For a simple, inexpensive second unit in a guest room or rental, it covers the basics.
Which window size fits a 12,000 BTU unit?
Most 12,000 BTU window units fit openings about 23 to 36 in wide. Check the model's stated range and minimum height before buying.
The LG needs a fairly wide opening at 23.6 in, while the BLACK+DECKER BD12WT6 works from 23 in. The Midea U-shape needs 22 to 36 in of width and 13.75 in of height because of its bracket.
The ROVSUN needs 25 to 36 in of width. The second BLACK+DECKER fits 26 to 36 in.
Single-hung, double-hung and slider windows
Most units here are built for double-hung or single-hung windows that raise and lower. A slider window needs a different mounting kit, so confirm the type before you order.
The LG, Amana and Whirlpool all ship with a window kit for standard hung windows.
Window width and height limits
Write down your opening's exact width and height before comparing models. A unit that's an inch too wide won't fit, and one that's too short leaves a gap that leaks hot air.
The Vtronix needs 16 in of height and the BLACK+DECKER BD12WT6 asks for 15.5 in.
What about the view and the window sash?
A standard unit fills most of the window and blocks the view. The Midea U-shape leaves the sash free to open, which is why it costs more and needs a wider opening.
How many square feet will 12,000 BTU cool?
A 12,000 BTU unit cools about 520 to 550 sq ft in a normal room. That's roughly a 22 x 25 ft space, so it suits a large bedroom, a living room or an open-plan kitchen.
The LG, Della, Midea and both BLACK+DECKER units list 550 sq ft. ROVSUN lists 520 sq ft.
The Amana, Vtronix and Whirlpool also list 550 sq ft. Pick by your room's measured floor area, not by how big it looks.
When to size up or down
Size up if the room gets strong afternoon sun, has a lot of glass or sits above a hot garage. Size down if the space is well shaded and only one or two people use it.
Our 10 000 btu window air conditioner guide covers smaller rooms.
Inverter or standard compressor: which should you buy?
Choose an inverter compressor for lower running costs and steadier temperatures. Choose a standard compressor for a lower upfront price and simpler repair options.
Inverter units here are the Della, Midea, ROVSUN and the second BLACK+DECKER. They vary compressor speed to hold a set temperature rather than switching fully on and off.
That means less temperature swing and less energy waste. The Midea rates 15 on efficiency and the ROVSUN lists a 15.0 CEER.
Noise and efficiency differences
The inverter units reach lower noise floors: 32 dBA for the Midea and 42 dBA for the ROVSUN in sleep mode. Standard units run at 53 to 56 dB.
Cost and repair considerations
A standard compressor has fewer electronic parts, which can mean simpler service down the road. An inverter unit costs more upfront but can pay that back in lower electricity use over several summers.
Check the stated annual energy use when comparing, since it varies widely across this group.
What should you check before buying a 12 000 BTU window air conditioner?
Check the window opening, the circuit and the noise rating before you buy. Those three decide whether the unit fits, runs safely and lets you sleep.
A 12,000 BTU unit draws around 9 to 11 amps running on 115V. A dedicated circuit is safer than sharing an outlet with a microwave or space heater.
The BLACK+DECKER BD12WT6 lists 9.72A and the second BLACK+DECKER lists 11A.
Electrical needs and outlet type
Most units here plug into a standard 115V outlet with a corded plug. Don't use an extension cord or a power strip for a window AC.
Check the breaker for the room before you install.
Noise levels for bedrooms
If the unit goes in a bedroom, pick by the dB rating. The Midea at 32 dBA is the clear winner for sleep, and the LG at 53 dB is a good compromise for a standard unit.
The Vtronix and Della sit at 56 dB, which is fine for a living room but noticeable at night. Our window air conditioner for bedroom guide goes deeper on quiet models.
Smart features and remotes: what's worth paying for?
Pay for smart control if you want to cool a room before you arrive home. Skip it if you're rarely away and the remote is enough.
WiFi, Alexa and Google Assistant control appear on the Della, Midea and Vtronix. They let you set a temperature from your phone or by voice.
The LG, both BLACK+DECKER units, the Amana and the Whirlpool rely on a remote only. Every pick here includes a remote in the box.
App and voice control
App control is most useful for a bedroom or office you cool on a schedule. Voice control suits a kitchen or living room where your hands are busy.
Remember that Della's WiFi runs on 2.4 GHz only.
Timer and auto restart
A 24-hour timer is the cheaper way to get scheduled cooling. Auto restart brings the unit back after a power cut, which matters in storm season.
The LG, Amana, Whirlpool and both BLACK+DECKER units list auto restart or a timer, and the smart units cover schedules through their apps.
Do you need a unit with heat for year-round use?
No, not if you only need summer cooling. A heat-capable unit costs more and adds a heating mode you may never use.
All nine picks here are cooling-only. If your room gets cold in winter and you want one unit for both seasons, look at our roundup of the window air conditioner with heat options instead.
Cooling-only vs heat and cool models
A cooling-only unit is simpler and usually cheaper. A heat-and-cool model adds a heating element or heat pump, which helps in a mild climate but adds cost and complexity.
Verdict: which 12 000 BTU window air conditioner should you buy?
Buy the LG 12,000 BTU for most rooms. It's the best 12 000 BTU window air conditioner overall because it combines 550 sq ft coverage, a 53 dB low setting, a timer, four-way air direction and auto restart without charging a premium for smart features.
Pick the Midea 12 if the unit goes in a bedroom and quiet is the top priority. Choose the DELLA 12000 BTU for smart control and an inverter compressor at a lower price than the Midea.
Go with the ROVSUN for the lowest running costs in a room up to 520 sq ft. If your opening is narrow or your budget is tight, the BLACK+DECKER BD12WT6 and the Vtronix Classic America cover the basics well.
For a basic rental unit, the Whirlpool 12 does the job, though its 72.8 lb weight makes the install a two-person job. Measure your window and your room's floor area first.
Those two numbers decide more than any feature list.

Frequently asked questions
What size room does a 12 000 BTU window air conditioner cool?
Most 12,000 BTU window units cool up to about 550 sq ft. Check each model's stated coverage, because a few here top out at 520 sq ft.
Is a 12 000 BTU window air conditioner enough for a living room?
It is enough for a living room up to 550 sq ft in a well-insulated home. A sunny room or one with a large west-facing window may need extra capacity or shade.
How many amps does a 12 000 BTU window air conditioner draw?
A 115V 12,000 BTU unit typically draws around 9 to 11 amps running. Check the model's rating and make sure the outlet's circuit can handle the startup surge.
Do 12 000 BTU window air conditioners need a special outlet?
No. Most 12,000 BTU window units run on a standard 115V household outlet.
They should still sit on a dedicated circuit where possible.
