6000 BTU Cools What Size Room?

Typically, a 6000 BTU air conditioner will cool rooms within the range of 150 to 250 square feet. Buying a large-size AC for small rooms might produce powerful cooling but weaken the unit’s compressor too quickly.

A 6K BTU AC in a large room will also overwork the unit and yield less than satisfactory results.

A few factors can affect the cooling power of ACs. For example, a room with access to direct sunlight might not be as cool as a heavily shaded one.

Equally, rooms near kitchens or with heat-generating appliances might not be as chill as other areas.

Review of the Best 6000 BTU Air Conditioners

Here is a small list of the top air-cons in the 6K BTU range that meet most users’ cooling needs. These are all window units from world-renowned brands, so you can expect them to perform excellently.

Best Overall:
Midea MAW06R1BWT

What Recent Buyers Report

Scores of buyers are happy with the cooling performance of the Midea MAW06R1BWT. Although some people say it is a two-person job because of its slightly heavy weight, it is easy to install.

Many customers appreciate that they can make any changes from across the room using the remote control.

Why it Stands Out to Us

This small air conditioner checks a lot of boxes for many users and us. First, it combines air conditioning, fan-only, and dehumidification in one unit for complete comfort at home or office. Plus, it provides fast cooling for areas up to 250 square feet.

You can conveniently set temperature, select operating modes, and program the unit using the intuitive remote control. Through some genius engineering, the unit can adjust the room’s temperature by sensing the distance of the remote control.

The model also features a filter light indicator that comes on when it is time to clean the air filter.

Bottom Line

To sum up, this is a nice little AC with an impressive cooling capacity and performance features.  We highly recommend this model for cooling small rooms. Its solid 1-year warranty assures you of a reliable product from a trusted brand.

What Recent Buyers Report  

Customers love the ease of controlling and monitoring the 6K BTU Friedrich Chill Premier using the app from just about anywhere.

Buyers readily testify that the air conditioner provides cost-effective cooling, thanks to its many energy-efficient features. However, several users find the initial Wi-Fi setup a bit tricky.

Why it Stands Out to Us

This model lets you operate the AC from anywhere through Friedrich Go App on your smartphone. You can schedule the unit to run on a specific temperature when you are away from home, a different one when you’re at home during the day, and yet another temperature during the night, all from the app.

But smart features aside, this is one of the highly-rated 6000 BTU air-cons in terms of energy efficiency. The cost of running this AC will not leave a dent in your wallet.

It comes with three fan speeds and distributes cool air in eight different directions.  

Bottom Line  

With an impressive energy efficiency rating (EER) of 11, you can expect to get cost-effective cooling from this smart window air conditioner. If you set it up correctly, your small bedroom or office will experience a chill like never before.

What Recent Buyers Report

The recurring complaint is that some of the units have damaged parts on arrival. However, in many cases, buyers receive prompt attention from customer support.

Why it Stands Out to Us

Air conditioners run best with clean air filters, and the AHQ06LZ model from GE Appliances has one of the most impressive easy-to-access filters.

The one-touch lift-out design makes it easy to remove, wash, and replace the air filter. Plus, the unit features a clean filter alert that reminds users to clean the component.

Like our runner-up product, this model comes with 11 EER, too, so it saves you tons of money on energy bills without compromising performance.

Other remarkable features include a 24-hour on/off timer, three fan speeds, three cooling speeds, and a built-in dehumidifier for humid days.

Bottom Line

This remarkable small air conditioner with money-saving features is worth considering, especially for rooms up to 250 square feet. If you are a light sleeper, we highly recommend this GE product for your bedroom because it operates very quietly.

Happy customers highly recommend the product, with some saying they will gladly buy another unit if the need ever arises.

Why it Stands Out to Us

LG did some amazing engineering with this small window air conditioner. It comes with the brand’s patented anti-corrosion gold fins to keep the air conditioner in good shape for a long time.

It can remove up to 1.8 pints of water from indoor air per hour, eliminating humidity and leaving you with cool, dry air. The energy saver function, combined with three fan speeds and a 24-hour timer, provides varying levels of flexibility.

Many ACs of this size do not have a remote control, but this one does. You can adjust all the settings from the device across the room.

Bottom Line

This could be the unit that will meet your needs if you are looking for a cute AC to cool a small apartment. Its performance features and multiple modes offer flexible cooling while saving you money in the long run.

Haier 6000 BTU Air Conditioner Review:
Haier ESAQ406T

Haier ESAQ406T Serenity Series 6, 000 BTU 115V Window Air Conditioner with Ultra Quiet Sound Package


  • One of the quietest 6000 BTU air conditioners available
  • Compressor blanket reduces sound level during operation
  • Distributes cool air in four directions (left, right, up, and down)
  • 4-in-1 function, including dehumidify, fan, energy saver, and cool
  • Highly-rated energy-efficient model consumes less energy for maximum cooling


  • Heavier than other models
  • More expensive than similar-sized models

What Recent Buyers Report

Apart from its powerful cooling, this is one of the quietest air conditioners in the 6K BTU range, according to many happy customers. Even light sleepers enjoy a peaceful night’s sleep with the air conditioner running. Plenty of buyers highly recommend the product, regardless of its slightly higher price tag.

Why it Stands Out to Us

From Haier’s serenity series comes this sleek and modern air conditioner with a 12.2 energy efficient rating, allowing you to enjoy cooling comfort at a highly reduced cost.

It is a feature-rich product with sleep mode, a cross-flow fan for better air distribution, and a dehumidifier.

The full-function remote control allows you to adjust temperatures and operation mode. There’s a “lock” button on the remote that prevents accidental changes to your preferred settings.

On top of it all, the AC operates at a mere 44 dBA (on low), making it one of the quietest air conditioners in the 6K BTU range.

Bottom Line

If you prefer Haier appliances, this air-con is one more reason to like the brand even more. The ESAQ406T will keep you very comfortable during the hottest months, plus you will be saving a lot of money on utility bills.

Frigidaire 6000 BTU Air Conditioner Review:
Frigidaire FFRE063WAE

Frigidaire FFRE063WAE Window Air Conditioner With Washable filter, remote, 6,000 BTU, White


  • Removes humidity up to 1.3 pints every hour
  • Lightweight window AC unit weighs only 47 pounds
  • Built-in timer to preset on/off in half-hour increments
  • Energy Star compliant model with 12.2 EER and fast cooling
  • Multiple fan speeds with 6-way airflow for maximum cool air distribution


  • Remote sensing below par
  • Louder than some similar models

What Recent Buyers Report

Many users attest that this model is more than adequate for cooling small rooms, and the eco mode saves the compressor from quick wear and tear. They also like the large vents, which allow more cool air to circulate better. It can be a bit loud, according to some users.

Why it Stands Out to Us

Cooling down a room is one thing, but distributing cool air to all parts of the room is a different ball game, and that’s one aspect this product excels.

The FFRE063WAE features larger vents than many other models, allowing it to circulate cool breeze in six different directions across the room for maximum comfort.

Removing and cleaning the washable air filter is a breeze with the tilt-out front access. It also features a filter light that lets you know when to clean it.

Other performance features include a full-function remote control, three fan speeds, dehumidifier, remote sensing, and sleep mode.

Bottom Line

Frigidaire’s 6K BTU model might be the right unit for your small room if you want a lightweight, fast-cooling AC. It is highly affordable compared to other similar-sized models, yet it saves you plenty of cash in the long run.

Comparison Overview 

People with small rooms have a handful of options when it comes to choosing the right air conditioner. Which is better: 5000, 6000, or 8000 BTU? Here’s a quick comparison overview to help you decide which is best for cooling down your space.

6000 BTU vs 8000 BTU


Most air conditioners in the 6K and 8K BTU range have similar dimensions and weight. Manufacturers tend to design these units to fit certain standard windows, so there’s no huge difference in the space they can fit into.

They also share similar performance features and come in portable, window, and through-the-wall varieties.


The major difference between these two is their cooling capacity. A 6000 BTU unit is your best bet if you want to cool down a room of about 150 to 250 square feet. If you plan on cooling areas above that dimension, you should be looking at an 8K BTU unit.

Frigidaire FFRE063WAE

5000 vs 6000 BTU

Although there’s only a 1K BTU difference between these options, it makes a huge difference in efficient cooling. The shape, size, type, and features of 5000 and 6000 BTU air conditioners are similar. However, 5K BTUs are only suitable for cooling rooms up to 150 square feet.


Your room’s size and the cooling capacity of an AC are two crucial things to remember when choosing an air conditioner. A 6000 BTU air-con is best for cooling small rooms up to 150 to 250 square feet.

Consider choosing an energy-efficient model with performance features for better cooling comfort.

People Also Ask

In the world of ACs, 6K BTU models are considered small appliances, but that doesn’t mean they won’t impact the overall energy usage in your household.

This section answers the common questions people ask about these small-sized units, especially as it relates to energy consumption.

How Many Watts Does a 6000 BTU Air Conditioner Use?

A 6000 BTU air conditioner uses approximately 500 to 750 watts, depending on the model's energy efficiency rating (EER).

6K BTU air-cons with an EER of 8 use 500 watts, while options with an EER of 12 will use 750 watts. A Higher energy efficient rating means less wattage.

Midea MAW06R1BWT

How Many Amps Does a 6000 BTU Air Conditioner Use?

The amperage estimates for a 6000 BTU air conditioner are between 4.35 and 6.52 amps, depending on the unit's make and model.

In most cases, it is okay to plug small-size air conditioners into wall sockets with a 15 amp breaker since they don’t draw too many amps.

How Much Does it Cost to Run a 6000 BTU Air Conditioner?

You can expect to spend anywhere between $50 and $75 per month. The actual amount depends on a few factors, including the AC’s EER, how long you use the air conditioner, and the settings. But whatever the cost, it is worth more than burning up in heat all day.
