A window air conditioner can be an affordable and powerful solution for cooling your home. Finding a suitable unit can be tricky if you have small windows, though. Yet, it doesn’t have to be.

I researched and tested dozens of window ACs to discover the smallest and most powerful window ACs out there. I’ve written this list based on my findings so your window size doesn’t stop you from staying cool.

ACLAB Note from the Editor:

All of the products I have included on my list require a window opening of at least 16 inches wide by 12.5 inches tall. While I applaud any creativity in forcing a window AC to fit, for people with smaller windows, I highly recommend going with a small portable AC that can vent out the window instead.

It is also worth mentioning that window ACs with small physical dimensions also have a low cooling capacity. Hence, they should not be treated as a replacement for high capacity large window ACs intended for larger rooms.

I live with roommates in a tiny West Village apartment, and my 10ft x 12ft bedroom only has one standard window, so everything in my life has to be quite compact.

I chose this Black+Decker model primarily because it was a household name growing up and one I knew my dad considered reliable. (Don’t worry, the AC isn’t their famous orange color!) 

What really sold me though was its slim design, which vertically would only block just over 12 inches of the window. This means that I’d still have my view of Washington Square Park, and be able to sleep through the night without sweating.

As far as small air conditioners go, this is about as small as they come.

The only unit shorter on my list here is the LG model below, but there you sacrifice width (over 17 inches compared to the B+D’s 16). 

I particularly like the Black+Decker model because it was in my price range, doesn’t have fussy controls, and just does what it says it will – keeps me cool in my small bedroom. 

A lot of the basic mechanical models I’ve tried over the years only have 2 or 3 cooling options, so I was pleasantly surprised that this one has 7 options to choose from, in addition to a “fan only” option, which I definitely appreciate in the springtime. 

On a level 4 I registered the fan noise as about 56 dB. Sure, it’s not the quietest window AC appliance on the market, but it is significantly more quiet than the box fan I had sitting in the window beforehand.

Who is the Black+Decker BD05MWT6 best for?

I recommend this Black & Decker window AC unit for people looking for a no-frills, no-fuss appliance that will easily fit into their small window without blocking too much of the view.

Store-brand items are a great way for companies to sell more premium items at a fraction of the cost, so it should have come as no surprise to me that Amazon would have its own line of Amazon Basics Window ACs. 

In fact, this model is nearly identical to the B+D one above. Its dimensions, weight, 5000 BTUs, controls, and room coverage are all exactly the same.

The Amazon Basics model even uses the same, newer R32 refrigerant, which is more efficient than the traditional R-410A and has no impact on the ozone later. 

I was just too curious, so I decided to try out both products side by side.

I’ll be honest, besides the obvious product branding - my top two smallest window ACs are twins in every which way. 

So, does Black+Decker make the Amazon Basics product? I’m sure that Amazon doesn’t kiss and tell, but I’d recommend these products equally. 

When it comes down to it, I’d likely recommend whichever you can get your hands on first.

In my area, Amazon Basics products typically offer same-day delivery, so that’s always a consideration for me.

Who is the Amazon Basics Window Mounted Air Conditioner best for?

The Amazon Basics model is best for anyone looking to save money by purchasing an Amazon-labelled product that features all the same benefits as my top small window AC.

Most of the window ACs on my list are 5000 BTUs, including the B+D, Amazon Basics, and GE models). 

It makes sense that the smallest window units would also have the smallest amount of power, but for those requiring a bit more oomph in cooling power, I recommend this 6000 BTU AC by LG. 

This window AC model is marginally wider than the first two models on my list, at just over 17 inches, and will still fit seamlessly in most windows. 

In terms of cooling power, though, LG squarely beats most other ACs here (except for the Midea U) and can cool a room up to 250 square feet. So, if your room is on the line of 150 square feet or more, I recommend sizing up to this model. 
LG LW6017R

This unit does cost more than its smaller 5K BTU competition, but you also get more bling for your buck.

To begin with, while this is far from being the most efficient Window AC, the 11.5 EER rating makes this window air conditioner more energy efficient than most others of this size.

You also get electronic controls and a remote.

The display allowed me to more accurately control the temperature than the mechanical air conditioners, but I found the remote control to be super picky about angle use, so I ended up only using the front panel for the most part.

My primary complaint with this unit is the instructions, which are really poorly translated.

Still, if you’ve ever successfully assembled IKEA furniture, I’m sure you can install this window AC as well.

The LG is a strangely quirky unit, but I’ll still recommend it if you need a compact air conditioner for a bigger room. It will keep you cool, no doubt about that.

Who is the LG Control 6,000 Window AC best for?

I recommend LG Control 6,000 window AC for those who want the compact size of a 5000 BTU machine but require a bit more power.

Pros
  • Good cooling capacity for the price
  • Affordable to buy and even more affordable to operate
  • Easy to install and keep window use
CONS
  • Unit can occasionally collect rain and drain into home

Full disclaimer: the Midea U isn't the smallest window air conditioner on my list — in fact, with a 22-inch width, it's definitely the widest (and heaviest at over 55 lbs). 

Most of the ACs I’ve included on my list, like the GE and the Amazon Basics models, only weigh about 35 pounds, so that’s definitely something to consider. 

However, this Midea unit has an ingenious space-saving trick up its sleeve.

I’m including this option on my list of the smallest ACs because its genius U-shaped design allows your window panel to slide between the front AC panel and the compressor. As long as you can get it in the window, it only takes up about 14” of vertical space.

I also love this model because it still allows me to open my window for fresh air from time to time.

Even more, though, I chose this model for my mom’s ground-level condo because it has an anti-theft mechanism that keeps the window locked and secure. 

This Energy Star-certified unit with an EER rating of 15 is the most energy-efficient on my list.

While you will see long-term savings on your energy bills, it’s definitely the most expensive product I’m including. 

This unit has an inverter compressor and built-in Wi-Fi capability.

I appreciate that this is actually a smart window AC. I can connect it to my smartphone to control it from anywhere. It also works with Alexa or other voice control units.

Overall, for anyone looking to cool a larger area with a small-profile window AC, I think you’d be hard-pressed to find an option better than the Midea U. 

I have found that the 8000 BTU unit works ideally in my mom’s 300-square-foot space, but Midea also has more powerful options that can cool up to 550 square feet with the same low profile.

Who is the Midea U 8000 BTU Window Air Conditioner best for?

I recommend this premium Midea U-shaped window air conditioner option for people who are looking to cool a large space of up to 350 square feet with a low-profile window unit.

  • Punches above its rated cooling power
  • Excellent value for money

  • No installation kit included
  • Product manual is difficult to understand

This Frigidaire window AC unit sets the industry standard in many ways.

It’s nearly identical to the other mechanical 5000 BTU models on my list requiring a 16-inch width, including the Black+Decker and Amazon Basics models.

So when it came time to review this product, I was really forced to focus on performance and any small differences between the models. Size-wise, any of these units would be ideal for my small space. 

The benefit of choosing this Frigidaire model is that it’s slightly more energy efficient than most 5000 BTU options and can move air incredibly fast. I could tell the temperature difference in my small bedroom in just 10 minutes.

The downside is that, unlike the other 5000 BTU models on my list, the Frigidaire doesn’t come with a mounting bracket or side panels for installation. 

I actually think that the company is a bit misleading here because it took me a bit of digging to see what I was actually getting.

My assumption of paying a similar price for similar parts was wrong, and these necessary installation pieces are sold separately.

As with most small window ACs, this unit doesn’t have a digital display, thermostat, or remote control.

You set the power with a 7-step turn dial and can choose between high or low cooling or fan functions.

That said, this year Frigidaire did release this same model with an electronic panel. I’m not sure it’s worth paying an additional $50, but I appreciate the option and knowing that the company is continuously working to improve their products.

Who is the Frigidaire FFRA051WAE best for?

I recommend this 5000 BTU Frigidaire FFRA051WAE window AC unit for those looking for a small air conditioner without accessories.

Danby is a Canadian company that many people aren’t familiar with, but having grown up in Michigan, I have used many of their products over the years. 

Their 5000 BTU model looks nearly identical to the Frigidaire model I reviewed above.

Unlike the Frigidaire unit, though, the Danby unit comes with everything you need to install it in a window, and for less money, too. 

Compared side-by-side, I think the plastic casing on the Danby model looks and feels a bit cheaper than the Frigidaire or Amazon Basics models. It’s still sturdy enough, though, and I wouldn’t hesitate to choose this option to save a little money. 

Like all the 5000 BTU models on my list, the Danby model is rated to cool 150 square feet. This is where I feel it falls a bit short.

I originally set it up in my 150-square-foot bedroom, but my window is on the wall opposite my bed, and I didn’t feel like it was keeping up, even when set at the highest speed. 

I ended up moving it into my home office (a 10 x 8 square foot room), and I feel like it’s much better suited there than my larger bedroom. I even find myself reaching for my cardigan most afternoons when it’s running, which is why I recommend this model for extra small spaces. 

Who is the Danby DAC050MB1WDB best for?

I recommend this small Danby DAC050MB1WDB window AC for those looking to cool an extra small space of 100 square feet or less.

Having been in the appliance and electricity industry since 1892, every American today probably has had a GE product in their home. 

They are definitely considered a top brand, so I assumed I would also be looking at a top price tag when it came to their small window ACs, but I was wrong!

Their 5000 BTU units are priced comparably to all of those on my list, including my top choice from Black+Decker

What really drew my attention to this GE model (besides its petite size requiring only a 17” window width) is that the controls are on the right-hand side, whereas every other model on my list (except the U-Shaped Midea model) has controls on the left side. 

To me, this is GE saying, “Hey, we just want you to know that we make all our own products. We don’t just slap our brand name on the same thing everyone else is using.”

That said, the controls themselves are pretty much the same. I ended up using the version with mechanical controls, but GE also offers this model with an LED panel for about $50.

As with the Frigidaire model, this price difference really depends on how important a touch panel is to you. 

This GE window unit is also the only model on my list with color options! All the models I reviewed come in the standard white, but GE has added a black option. It’s slightly more expensive, but I went with the black because it stands out less in my brick loft apartment.

Who is the GE Window AC best for?

I recommend this AC Unit from GE for people wanting a reliable, no frills model that will last a long time.

  • Unique saddle design leaves the view unobstructed
  • Extremely quiet operation
  • Well-functioning portable thermostat
CONS
  • Expensive to buy and own
  • Saddle design may not work for all windows
  • The inside part can fill with condensation

It’s a fact of nature that even small window air conditioners are loud — unless you go for Soleus Air WS3-06E-201. This is quite possibly the quietest window air conditioner I’ve seen.

In the low setting, this unit makes only 38 dB of noise — even quieter than a hushed library. The 49 dB produced in the highest setting is still quieter than most other window AC units on my list in their lowest setting.
Soleus Air WS3-06E-201

It’s all thanks to the U-shaped saddle design. Unlike the Midea U, though, this window AC curves downward. 

That places the compressor behind your home’s wall, which blocks most of the noise.

This design doesn't block your window, so you can still enjoy the view. You can also open the window if you can be bothered to remove the insulation strips.

So is Soleus a small window air conditioner? Depends on how you look at it. It's only an inch wider than the extra-narrow Frigidaire unit. 

It also doesn't take up much vertical space on the window sill.

That said, you need 19” of vertical clearance to fit the compressor through the window opening. 

You may also not be able to install this unit if you have a radiator or something else directly below your window since the AC and compressor hang downwards.

I’d say this unit is small, with an asterisk.

It’s quite powerful, though, matching the LG machine with 6,000 BTU. It can cool rooms up to 250 square feet very fast.

The Soleus has a portable thermostat built into the full-function remote control.

This is the most energy-efficient unit I’ve reviewed after the super-thrifty Midea U — in theory. 

The unit itself is very expensive. It’s around the same price as the Frigidaire unit. 

You’ll have to decide for yourself if the unique form factor is worth the price.

One thing I do want to warn you about the dreaded FL error code, which means the front part has filled with water and you have to drain it — from the indoor side. Make sure to tilt the AC backward to avoid running into this issue too often.

You’ll have to dig deep to purchase this unit, but if you want a super quiet AC, it just might be worth it.

Who Is Soleus Air WS3-06E-201 Best For?

This Soleus Air WS3-06E-201 unit is a good fit for those who want a very quiet small window air conditioner and still see out of the window.

How To Choose A Small, Yet Reliable, Window AC

I’ve reviewed plenty of small window air conditioners, and many of them are admittedly very similar.

Here are my brief top tips on how to find a cool needle in a stack of window air conditioners. 

Alternatively, check out my - Window AC Buying Guide

Pay Attention To The Unit’s Size

I recommend measuring your window very carefully before you start looking for an AC unit to ensure it’s the right size for your window opening.

Most window AC units on my list measure 16 inches in width and 12 inches in height, which is a fairly standard baseline for a “small” air conditioner. 

Small window air conditioner

ACLAB note:

Note that the minimum window width and minimum window height a unit actually needs are usually about an inch higher than the AC’s dimensions. After all, you need space for the mounting brackets and side panels. An average, a small Window AC is 16 inches in width and 12 inches in height.

I’ll explain my criteria for picking the AC models on my list later, so keep reading.

Window-Mounted Air Conditioner in Living Room

ACLAB Note

Window ACs are generally designed for vertical sliding windows. For horizontal sliding or casement type windows, you may need to look into sliding Window ACs.

Understand The AC Unit’s Cooling Capacity (BTU)

In general, you should look for window-mounted air conditioners with at least 5,000 BTU of cooling capacity to ensure they can cool your room efficiently.

The cooling power of a window AC unit is measured in British thermal units. 

A 5,000 BTU window air conditioner — like the small Frigidaire and Midea models — is sufficient for cooling a room of up to 150 square feet.

I recommend measuring your space’s square footage and comparing it against a BTU value chart. You can then easily see what kind of cooling output you need.[1]

ACLAB Note:

Cooling capacity is measured in BTU. Small Window ACs have a BTU rating of about 5000.

Match capacity with room size

Energy Efficiency (EER) Matters

I advise you to aim for an EER rating of at least 11 so you can run your air conditioning unit for long periods of time without a sky-high energy bill.

Energy efficiency ratings are luckily very easy to understand. The higher the energy efficiency ratio (EER) the mini AC window unit has, the less power it consumes.[2]

All models on my list hover around the 11 EER level, but some, like the Midea U, have extremely low power consumption.

ACLAB Tip:

Look for an Energy Star label, which certifies the unit’s energy efficiency. The higher the EER rating, the more energy efficient a unit is.

EER Rating

Listen To The Noise Levels

My recommendation is to choose a window air conditioning unit with a maximum rated noise level below 55 dB to avoid excessive noise.

There are no silent window AC units, but a 55dB model will not be overtly loud. At that noise level, the unit will be quieter than a normal conversation.[3]

ACLAB Note:

Keep in mind that manufacturers often use some tricks to make their units seem quieter than they are, like measuring the decibel level at the machine’s lowest setting from far away. The quieter the window AC the more comfortable the experience. Look for Window ACs with rated dB of less than 55. 

If silence matters to you, I would recommend choosing a small unit with a U-shaped design, like Midea U or Soleus.

Know The Filters And Vents

Aim to purchase a unit with a washable dust filter and, ideally, a split air vent with eight-way adjustment.

Washable filters can be cleaned with mild soap and warm water, which helps you keep your unit’s running costs lower. 

Pay attention to the exhaust vents on the unit’s back compressor as well. Some small units (looking at you, Midea) have vents that face upward, which can allow rainwater to seep inside.

Tip:

A Window AC with washable filters and split front air vents is recommended.

Consider Maintenance Needs

You should look for air conditioners with a front-loading filter/maintenance hatch, although that is often not an option with the smallest window air conditioners.

A front hatch gives you access to the filter while also allowing you to easily clean the fan and coils inside the air conditioner. 

Most small AC units, however, have a side-sliding filter, which works fine but requires extra space around the unit.

You will likely have to undo some screws to open the unit for cleaning with a small air conditioner.

Optional Extras

Depending on your needs, you may want additional features in your AC.

The smallest units are often limited in this regard, but here are some common functions to keep an eye out for:

  • Dehumidifier:
    Removes moisture from indoor air, which can keep you more comfortable in high summer humidity and prevent mold growth.
  • Temperature Settings:
    Most small window air conditioners have a basic turn dial for setting the temperature, but you can find small units that enable auto-shutoff, allowing the unit to turn off when your room gets cool enough.
  • Display:
    Having even a small display makes controlling the AC’s output a lot simpler. Basic small units rarely have one, but some — like the LG — do.
  • Remote Control:
    It’s not a dealbreaker for me, but having a good remote control is a nice touch.
  • Wi-Fi Connectivity:
    The ability to connect your small AC to smart devices through Wi-Fi will make it more expensive, but I’d lie if I said I didn’t enjoy adjusting the Midea U through my phone.

Note From The Editor:

Window ACs can have several additional features that can make your experience better and the unit more efficient such as Wi-Fi connectivity and capacitive touchscreen display for precise control. However, these can add to the overall cost.


How I Found The Best Small Window AC Units

Reading through my reviews, you may have wondered why I chose to feature these AC units. Let me give you a behind-the-scenes look at how we do things here at Air Conditioner Lab.

I spent a lot of hours evaluating the specifications and statistics of more than 30 air conditioner models.

In addition to the brands you saw on my list, I researched brands like Homelabs, GE, Haier, and so forth.

Before getting into finer tests, I needed to determine what an average small window air conditioner is like — after all, I had to have a base standard I could compare other units to.

Based on my research, the average "small" AC is about 16 inches wide and 15 inches tall and weighs 40-45 pounds.

After thoroughly putting the units through their paces, I chose the eight that I feel have the best balance of various factors, like size and weight, cooling capacity, consumer experiences, warranty, and more.


FAQs

What Happens if the Window AC is Too Small?

If your AC is too small, it will struggle to properly cool your room. Whether it’s too small size-wise or too low-power, an undersized air conditioner can’t eliminate hot air to keep you cool.

Are Small Window Air Conditioners More Energy Efficient?

Small air conditioners are generally more energy efficient than larger ones, not to mention central AC units. They’re designed for smaller spaces with less powerful and power-hungry compressors, which can help keep your bills low.

How Long Do Small Window Air Conditioners Last?

On average, small window air conditioners can last around 8-10 years. Their ultimate lifespan depends on how well you care for the unit — a well-maintained and cleaned AC can last for many years more.

How Many Watts Does a Window AC Use?

Small window ACs typically use about 450-800 watts of power. You can compare that to medium and large air conditioners, which typically require around 1,000 and 1,400 watts, respectively.

How Many Amps Does a Window AC Use?

Smallest window ACs typically use 5-10 amps. Larger units require more power and may go all the way up to 20 amps. Pay attention to the amperage, as plugging a small unit into a 20-amp or higher breaker could overload it.

How Do You Clean a Window AC Unit?

To clean a window AC unit, you have to open it, remove and replace or wash the filter, vacuum up any debris, and wipe the interior with a hydrogen peroxide solution. Consider also carefully straightening any crooked fins.

Summary - Which Should You Buy?

Whether I'm trying to cool a room with limited space or just small windows, there's a window AC that fits the bill. 

Needing only 12" of clearance, the Black+Decker BD05MWT6 is typically my go-to for these situations. Still, I think you can't go wrong with choosing any of the small window units I've listed above.
