The best 14,000 BTU window air conditioner for most large rooms is the DELLA 14000 BTU Energy Saving Window Air, which cools up to 700 sq ft and adds Wi-Fi, app and voice control at a 69.4 lb install weight. Pick the Midea 14 if you want the quietest unit here and lower running costs from its inverter compressor.
Pick the LG 14 if your room runs closer to 800 sq ft.
A 14,000 BTU window unit is the right step up when a 10,000 BTU model leaves a big living room or family room warm. These units cool roughly 700 sq ft, which covers most open living areas.
The trick is matching capacity to the room and the window. A unit that's too small runs all day without reaching the set temperature.
One that's too large short-cycles and leaves the air clammy. Our guide to how many BTU per square foot an air conditioner needs walks through the math.
If your window can't take a heavy unit, a 14,000 BTU portable like the Dreo is the fallback, and our window air conditioner buying guide covers fit and installation.

The best 14,000 BTU window air conditioners for large rooms
The DELLA wins on the balance of cooling reach, smart controls and a moderate install weight. Every other pick is the best choice for a named need: quieter operation, a wider window fit, or a longer warranty.
DELLA 14000 BTU Energy Saving Window Air: Best for most large rooms
- Cools up to 700 sq ft
- CEER 10.7
- Wi-Fi with DELLA+ app, Alexa and Google Assistant
- 54 dB low noise
- Fits windows 26 to 36 in wide
A balanced smart window unit for big living rooms. It covers 700 sq ft with app and voice control at a weight most two-person teams can handle.
Pros
- Wi-Fi plus app and voice control
- Cools up to 700 sq ft
- Rated 10.7 CEER
- 54 dB low noise
Cons
- Wi-Fi only on the 2.4 GHz band
- No inverter compressor
The DELLA is the pick for a big living room or family room where you want to set the temperature from the couch. It cools up to 700 sq ft and rates a CEER of 10.7.
Smart control runs through the DELLA+ app, with Alexa and Google Assistant voice commands. That's more than most rivals here offer at this score, and it works over the 2.4 GHz Wi-Fi band only.
The unit runs at 54 dB at its quietest, which suits background cooling in a shared room. Installation needs a window 26 to 36 in wide and at least 16 in high.
At 69.4 lb it's a two-person lift, but lighter than both LG dual inverter models. You get four modes (Auto, Cool, Fan, Dry), three fan speeds and a 24-hour timer.
The trade-off is the standard on/off compressor, so running costs are higher than the Midea's when the unit runs for long stretches.
Midea 14: Best for quiet bedrooms
- Variable-speed inverter
- 41 dBA low noise
- Energy Star certified
- Cools up to 700 sq ft
- Alexa and Google Assistant
The quietest pick here, with inverter technology that trims running costs. It suits a bedroom or home office where fan noise is the deciding factor.
Pros
- 41 dBA in low mode
- Inverter compressor with big energy savings
- Lightest unit in this group at 63.5 lb
Cons
- Highest-scoring rival costs less to run at full load
- No heat pump
Midea is the choice for a bedroom or home office where noise decides the purchase. It runs at 41 dBA at its quietest, the lowest figure in this group.
The variable-speed inverter saves more than 40% on electricity against the Energy Conservation Standard, per Midea, and the unit is Energy Star certified. That matters if the AC runs overnight.
The SmartHome app, Alexa and Google Assistant cover control from your phone or voice. At 63.5 lb this is the lightest unit here, so moving it in and out each season is easier than the heavier LG.
It cools up to 700 sq ft. The gap to the DELLA is small.
Midea scores just below because its smart features and room rating match the DELLA rather than beat it. Buy it if quiet running is worth more to you than a hair more score.
GE Window Air Conditioner 14000 BTU: Best for SmartHQ households
- Energy Star certified
- SmartHQ app plus Alexa and Google Assistant
- Eco Mode
- Slide-out washable filter
- Fits windows 25 to 36.625 in wide
A fixed-chassis smart unit with a wide window fit range. Eco Mode and three fan speeds keep it flexible, though it is heavier than the top pick.
Pros
- Eco Mode cycles the compressor
- Energy Star certified
- Slide-out filter
- Broad window fit range
Cons
- Heaviest unit here at 72 lb
- 63 dB top noise
The GE 14000 BTU unit suits a home already set up with SmartHQ or Alexa. It cools up to 700 sq ft and is Energy Star certified.
Eco Mode turns off the fan and compressor once the room hits your set temperature. Three cooling modes and three fan speeds give you flexibility between full cooling and a gentler setting.
The slide-out washable filter cleans easily and should be rinsed every 30 days. Fit needs a double-hung window 25 to 36.625 in wide and at least 14.563 in high.
At 72 lb it's the heaviest unit here after the LG slide-out model. That's the main reason it sits at 9.1 rather than the top.
It also runs louder at 63 dB at its top setting. Buy the GE for the wide fit range, Eco Mode and familiar smart app.
LG 14: Best for extra cooling reach
- Cools up to 800 sq ft
- Dual Inverter compressor
- 44 dB in sleep mode
- LG ThinQ, Alexa and Google
- Washable dust filter
LG rates this unit for 800 sq ft, the largest coverage here. The dual inverter design and 44 dB sleep mode suit open-plan spaces.
Pros
- 800 sq ft coverage rating
- Dual Inverter with 35% energy savings claim
- 44 dB sleep mode
Cons
- Wider cabinet at 23.62 in
- No stated weight in this data
The LG 14 is the best choice when your room runs bigger than 700 sq ft. LG rates this unit for 800 sq ft, the largest coverage in this roundup.
A dual inverter compressor and 44 dB sleep mode make it a strong fit for open-plan living spaces. LG says the inverter design saves up to 35% against the Energy Star requirement.
It works with LG ThinQ, Alexa and Google Assistant for app and voice control. The washable dust filter is easy to pull out and clean.
The cabinet is wider than most here at 23.62 in, so measure the window before ordering. Its fit range is listed for a double-hung window with the included EZ Mount kit.
This is the LG to pick for raw coverage. The slide-out LG model below has the easier seasonal removal but a smaller rating.
BLACK+DECKER Window Air Conditioner 14300 BTU: Best for a standard window fit
- 14,300 BTU
- Cools up to 700 sq ft
- R32 refrigerant
- Full-function remote
- Fits windows 23 to 36 in wide
A slightly stronger 14,300 BTU unit with the narrowest window requirement here. It suits older frames and simple remote control.
Pros
- Narrowest window fit at 23 in
- 14,300 BTU cooling
- R32 refrigerant
Cons
- No Wi-Fi or app control
- No Energy Star rating
BLACK+DECKER suits older homes with narrower window frames. It fits double-hung windows from 23 to 36 in wide and as low as 15.5 in high, the narrowest fit here.
That makes it the pick when the opening is snug. It pushes 14,300 BTU and cools up to 700 sq ft.
The accordion side panels and foam weather stripping simplify a DIY install. A full-function remote covers sleep mode, energy saver and the 24-hour timer.
R32 refrigerant is part of the pitch. The CEER comes in at 10.9, slightly above the DELLA.
There's no Wi-Fi or app control, though, so you'll use the remote or the panel. This is the simple, sturdy option.
If you don't need smart features and your window is on the small side, it does the core job well.
GE 14: Best for open living spaces
- Cools up to 700 sq ft
- SmartHQ app plus Alexa and Google
- Eco Mode
- Washable filter
- Fits windows 26.13 to 37.75 in wide
A lighter smart GE for studios and open family rooms. The 66.1 lb cabinet and quick install kit make it easier to move than the older GE.
Pros
- Lighter than the other GE at 66.1 lb
- Eco Mode
- Quick install kit
- Wi-Fi and voice control
Cons
- No Energy Star certification in this data
- Narrower window fit than the 14K GE
This GE 14 is the lighter smart option for studios and open family rooms. At 66.1 lb it's easier to handle than the 72 lb GE above.
It cools up to 700 sq ft and works with SmartHQ, Alexa and Google Assistant. Eco Mode turns the unit off when your room reaches the target temperature.
Three cooling modes and three fan speeds let you trade a little cooling for less noise. A quick install kit is included for a double-hung window 26.13 to 37.75 in wide.
The trade-offs are clear against the other GE. It lacks the Energy Star certification the 14K GE carries, and its window fit range is narrower.
The lighter cabinet is the reason to choose it. Buy this one for a rental or a room where you'll pull the unit each fall.
LG 14000 BTU Window Air Conditioner Energy: Best for renters who move units
- Dual Inverter compressor
- 44 dB sleep mode
- LG ThinQ, Alexa and Google
- Slide-in and slide-out chassis
- Cools up to 700 sq ft
A dual inverter LG with a slide-out chassis that simplifies seasonal removal. It is heavy at 85 lb, so plan for two people.
Pros
- Slide-in and slide-out chassis
- Energy Star certified
- Inverter compressor
Cons
- Heaviest unit in this group at 85 lb
- Smaller coverage rating than the other LG
The second LG is the pick for renters and anyone who stores the unit each winter. Its slide-in and slide-out chassis lets you pull the cabinet from the window frame without removing the whole mount.
That's the easiest seasonal removal here. It's a dual inverter unit with 44 dB sleep mode and a 700 sq ft rating.
LG ThinQ, Alexa and Google Assistant handle app and voice control. The slide-out filter makes monthly cleaning simple.
The weight is the catch. At 85 lb it's the heaviest unit in this roundup, so two people should handle install and removal.
Its coverage rating is smaller than the other LG, too. Buy it for the chassis design and the inverter savings if you move the unit often.
Skip it if you want the largest room rating or the lightest cabinet.
Hisense 14: Best for long warranty cover
- Cools up to 700 sq ft
- ConnectLife app control
- Four-way air direction
- Three modes including dehumidifier
- 2-year warranty
A straightforward smart unit backed by a 2-year warranty. Four-way air direction helps push cool air into the corners of a long room.
Pros
- 2-year warranty
- Four-way air direction
- 67.5 lb install weight
- Dehumidifier mode
Cons
- 56 dB low noise
- No inverter compressor
Hisense suits buyers who want longer warranty cover. The 2-year warranty is twice what many units in this group offer.
It cools up to 700 sq ft and runs three modes, including a dehumidifier for sticky summer days. Four-way air direction spreads cool air into the corners of a long room.
The ConnectLife app gives remote control from your phone, and an included remote and touch panel cover in-room changes. At 67.5 lb it's a manageable install.
Noise is the trade-off. It runs at 56 dB at its quietest, louder than the Midea or either LG.
There's no inverter compressor either, so running costs sit closer to the DELLA than the Midea. Buy it for the warranty and even air spread in a living area.
If quiet nights matter more, the Midea is the better fit.
How these 14,000 BTU window air conditioners compare
All eight units cool around 700 sq ft, so the real differences are smart control, compressor type, noise and window fit. The table below lines up the specs that decide the purchase.
| Product | Best for | Cooling power | Room size | Weight | Our score |
|---|---|---|---|---|---|
| DELLA 14000 BTU Energy Saving Window Air | most large rooms | 14,000 BTU | Up to 700 sq ft | 69.4 lb | 9.7 |

| Hisense 14 | long warranty cover | 14,000 BTU | Up to 700 sq ft | 67.5 lb | 8.1 |
Our score weighs specs, features and fit against what you're shopping for in this size class. Cooling reach and smart control carry the most weight.
Noise, install weight and window fit separate the close calls. The DELLA takes the top spot because it combines 700 sq ft coverage with app and voice control at a moderate 69.4 lb.
The Midea loses by a hair on smart reach, not on quality.
How we compared these units
We checked the specs and features each brand publishes for its 14,000 BTU window unit. Cooling power and room ratings came first.
Smart control and compressor type came next, since those decide running costs and daily convenience. Install weight and window fit ranges broke the ties.
We did not run any unit in a test room. Scores reflect how each model fits a buyer shopping this size class.
What room size does a 14,000 BTU window AC really cool?
A 14,000 BTU window unit cools about 700 sq ft in a typical room. LG rates one model here for 800 sq ft.
That's a normal living room, a family room or a large open space. The square footage is a starting point, not a promise.
A kitchen open to the living room adds heat from cooking. A wall of south-facing windows adds solar gain.
An attic room with a low ceiling traps warm air. For those rooms, aim lower on the square footage or step up in capacity.
Measure the room's length and width and multiply them. A 25 by 28 ft living area is 700 sq ft.
If your count lands between 600 and 750 sq ft, a 14,000 BTU unit like the DELLA or Midea fits. Above 800 sq ft, split the space or move up a size.
Should I size up or down?
Size down if your room is shaded or you mostly cool one zone. Size up if the space is open to a kitchen or gets direct afternoon sun.
A unit that's slightly small runs longer but removes more humidity. One that's too large short-cycles and leaves the air feeling damp.
Our 10,000 BTU window air conditioner roundup covers the next step down if your room is closer to 450 sq ft.
Does an inverter compressor matter in a 14,000 BTU unit?
Yes, if the unit runs many hours a day. An inverter compressor varies its speed instead of switching fully on and off.
That means steadier temperatures and lower electricity use over a long cooling season. Three units here use inverters: the Midea 14, the LG 14 and the LG slide-out model.
Midea claims more than 40% energy savings against the Energy Conservation Standard. LG claims up to 35% against the Energy Star requirement.
Both brands back the claims with Energy Star certification. The DELLA and both GE units use standard compressors.
They cool just as hard at full load. The difference shows up in running costs and temperature swings.
If you cool a room for four hours on weekend afternoons, a standard compressor is fine. If the AC runs overnight every night from June to September, the inverter units pay back the difference.
Treat the brand claims as directional. An inverter unit also runs quieter at partial load, which is why the Midea and LG models score well on noise.
Which 14,000 BTU window unit is quietest?
The Midea 14 is the quietest unit here at 41 dBA. The two LG models follow at 44 dB in sleep mode.
The DELLA runs at 54 dB and the Hisense at 56 dB. The GE units reach 63 dB at the top fan setting.
Decibels are a log scale, so each 10 dB step roughly doubles perceived loudness. The gap between 41 and 63 dBA is large in a quiet bedroom.
If the unit sits near where you sleep or take calls, the Midea is the clear pick. Noise also depends on the fan speed.
Most units run quieter on low or sleep mode. Check the low-speed figure when you compare, since that's what you'll hear most nights.
Will a 14,000 BTU window air conditioner fit my window?
Fit varies more than you'd expect in this size class. Measure the window's width and the sash height before you order.
The narrowest fit here is the BLACK+DECKER at 23 in wide. The LG slide-out model has the widest fit at 39 in.
Here's the range for each unit:
- BLACK+DECKER: 23 to 36 in wide, 15.5 in high minimum.
- GE 14000 BTU: 25 to 36.625 in wide, 14.563 in high minimum.
- DELLA: 26 to 36 in wide, 16 in high minimum.
- GE 14: 26.13 to 37.75 in wide, 15.63 in high minimum.
- LG 14: double-hung window, EZ Mount kit included.
- LG slide-out: 27 to 39 in wide, 16 in high minimum.
Most units need a double-hung window. A slider or casement window may need a different bracket or a different model.
The install kit covers weather sealing and support, but the window must carry the unit's weight safely. A 14,000 BTU unit weighs 63 to 85 lb.
Use the included bracket and sill supports. For upper-floor windows, add a secure mount that meets local rules.
If the frame feels loose or the window is very old, have a handyman check it first. Never trust foam alone to hold the unit.
If your opening is narrower than 23 in, a window unit in this class won't fit safely. Look at a portable model instead.
Our Dreo 14,000 BTU portable review covers a strong option for small or awkward windows.
Do smart features change how you use a window AC?
Yes, mostly in convenience. A Wi-Fi unit lets you cool the room before you get home.
You can change the temperature from bed or turn it off if you forgot. The DELLA, both GE units, both LG models and the Hisense all offer app or voice control.
The BLACK+DECKER is the only unit here without Wi-Fi. It runs from a full-function remote and the panel.
That's fine if the unit sits in a room you pass through often. Smart control matters more for bedrooms and for homes where you're away during the day.
Two details to check. The DELLA's Wi-Fi works on the 2.4 GHz band only, which is normal for these units.
And each brand uses its own app, so a house with GE and LG units needs two apps. Voice assistants like Alexa and Google Assistant can unify the everyday commands.
Pick smart control if you want to pre-cool the room or check the unit when you're away.
How much does it cost to run a 14,000 BTU window AC?
The running cost depends on the compressor type and how long the unit runs. An inverter unit like the Midea or LG uses less electricity over a long season.
A standard unit like the DELLA costs more per hour at full load. Energy Star certification helps you compare.
The Midea, the GE 14000 BTU and both LG units carry it. The DELLA, the GE 14 and the BLACK+DECKER do not.
The DELLA still rates a CEER of 10.7, and the BLACK+DECKER rates 10.9. Those are decent figures for standard compressors.
The gap to an inverter unit shows up when the AC runs for hours. For a short afternoon cool-down, the difference is small.
The Midea 14 is the strongest bet on running costs. It has an inverter compressor, Energy Star certification and the lowest noise in the group.
The LG models are close behind with their dual inverter design.
How should you set up and care for a 14,000 BTU window unit?
Set the unit level in the window with a slight outward tilt so condensate drains outside. Seal the gaps with the foam strips in the kit.
Leave the filter easy to reach, since every unit here has a washable one. Clean the filter every 30 days during cooling season.
A clogged filter cuts airflow and makes the compressor work harder. The GE units and both LG models use slide-out filters that are simple to pull.
The DELLA's filter is also easy to remove. Rinse with water and let it dry fully before replacing it.
In a dusty home or a room with pets, clean it every two weeks. A dirty filter is the most common cause of weak cooling.
If the unit runs but the air feels warm, check the filter before calling for service. At the end of the season, unplug the unit and clean the filter one more time.
Cover the outside of the unit or remove it for storage. The LG slide-out model makes removal easiest.
Store the remote and bracket screws together so you can find them next spring.
Verdict: which 14,000 BTU window air conditioner should you buy?
The best 14,000 BTU window air conditioner for most large rooms is the DELLA 14000 BTU Energy Saving Window Air. It cools 700 sq ft and adds Wi-Fi, app and voice control at a 69.4 lb install weight.
That mix of reach and smart convenience is hard to beat in this group. Pick the Midea 14 if you want the quietest unit and the lowest running costs from its inverter compressor.
Pick the LG 14 for a room closer to 800 sq ft. Pick the BLACK+DECKER if your window is narrow and you don't need smart control.
For a unit you remove each winter, the LG slide-out model's chassis design is worth the extra weight. And if your window can't take a window unit at all, a portable model is the answer.
Our window air conditioner buying guide helps you decide between the two types before you spend.

Frequently asked questions
Is a 14,000 BTU window AC enough for a large living room?
Yes, for most living rooms up to about 700 sq ft. Rooms that are open to a kitchen or have big south-facing windows need more capacity than the square footage suggests.
Check our BTU per square foot guide before you commit.
Do I need an inverter window air conditioner?
An inverter compressor runs at variable speed and saves energy, as the Midea and LG models do. Standard compressors cycle on and off and cost more to run at full load.
Pick inverter if the unit runs many hours a day.
Can I control a 14,000 BTU window AC from my phone?
Several picks here connect to Wi-Fi. DELLA uses its DELLA+ app, GE uses SmartHQ, and both LG units and the Hisense work with their own apps.
The DELLA, GE, Midea and LG units support Alexa or Google Assistant voice control.
What window width do I need for a 14,000 BTU unit?
Fit ranges vary by model. The BLACK+DECKER fits windows from 23 to 36 in wide, while the DELLA needs 26 to 36 in.
Measure your window opening and the sash height before ordering.
