6000 BTU AC Units

Find your next AC unit as we compare the top brands for home cooling at this size.

Air conditioners help provide a cool environment for homeowners and make homes comfortable regardless of how hot it gets outside. It can be uncomfortable when high outdoor temperatures make their way indoors and can even be dangerous if temperatures reach heatstroke conditions.

A portable AC unit or window AC unit can help cool down the essential rooms in your home and provide comfortable chilled air.

If you want to purchase a 6000 BTU AC unit for your home, these are our top nine options to keep your home cool all year long.

Understanding BTUs: When Is a 6000 BTU AC Right For You?

A BTU is a British thermal unit, and it measures the energy required to raise a single pound of water 1 degree. When consumers see the BTU rating, it measures how many BTUs can be added to the air or removed from it. The more BTU’s that a model has, the greater the square footage that the model can cool.

For example, 6000 BTU AC units will cool off spaces ranging from 150 to 250 square feet. Another example would be 8000 BTU AC units, which can cool approximately 350 square feet. Consider the size of your home or the size of the room you want to cool before making a choice.

Considerations When Buying a 6000 BTU AC Unit

AC Type

We have two primary AC types to choose from when it comes to 6000 BTU AC units: window AC units and portable AC units. Window AC units are installed in the windows of a homeowner’s residence, and portable AC units are wheeled from room to room. A portable AC typically stands on its own and has a vent that is placed in the window.

We recommend window AC units for homeowners who do not need to close their windows, want to save space in their room, or who plan to keep their AC unit in one room. We recommend portable AC units for homeowners who want to be able to move their AC unit from place to place or apartment renters who want to be able to remove the vent and close their window when they leave.

Coverage Area

Consider the coverage area that you need and the BTU rating you need. The 6000 BTU air conditioner unit can cool off approximately 150 to 250 square feet. We recommend placing a 6000 BTU air conditioner unit in a confined space. If you have an open floor plan, this AC unit can still provide cold air, but may not cool off the area to the correct temperature setting chosen on the unit. This unit is particularly great for bedrooms, offices, kitchens, and small living rooms.

Energy Efficiency Rating (EER)

The Energy Efficiency Rating, also known as EER, is the rating of how well your air conditioning unit can cool off the room compared to the wattage it uses. A high EER rating means that your air conditioner unit is more efficient and effective. It also means that you will have a lower overall cost when running the unit. High EER ratings can save homeowners money and typically point to higher-quality units that are more durable.

Noise Levels

The noise levels for AC units are measured in decibels or dba. The optimal noise level for you depends on your needs. The more expensive AC units will have lower noise levels at approximately 25 to 35 dB. However, most 6000 BTU AC units hover around 50 to 65 dB. For reference, a refrigerator hum is often 40 DB. Consider whether or not noise levels are important to you and then choose an AC unit that meets those sound needs.

Performance Features

The 6000 BTU air conditioner units on our list come with a variety of different performance features. There are multiple fan speed options, auto settings that allow users to create different presets, remote control operation, sleep mode settings, dehumidifier options, and even different timer settings. We recommend looking at each air conditioner unit’s performance features and choosing the one with the most features that fit within your budget.

Installation Requirements

Every 6000 BTU air conditioner unit comes with its own installation requirements. First, users must access whether or not they want a window unit (needs to be installed in a window) or a portable unit (only the vent will be filtered through a window). Then, we recommend reviewing whether the AC unit will require 120V or 240V. Look at mounting options as well and make sure that the unit will fit with your home’s structure.

Price & Warranty

Not everyone has an unlimited budget, and we recommend that customers review costs when making their decision. There are great AC units at every price point. However, be aware that the best warranties tend to belong to the more expensive AC units. A stronger warranty can make more sense for a customer who values purchasing a reliable and durable machine. Most 6000 BTU air conditioning units come with a one-year limited warranty, but a few brands offer three to five-year warranties.

Types of AC Units With the 6000 BTU Rating


lg window acAn AC unit that is placed in the window.

These are common in the 6000 BTU category because 6000 is enough power to cool approximately 260 sq. ft.

These window units are perfect for homeowners who want to cool down a particular room and do not require a whole-house A/C unit such as a mini split system.

These window units are also ideal for those who simply want to save money by not running their whole house A/C unit at night and only running their bedroom window AC unit.


The 6000 BTU portable units are small units on wheels that can be moved from room to room in your home. These units typically have a vent that must be placed in a window, but the machine itself is portable and on wheels. To move, customers simply remove the vent, wheel the unit into a new room, and place the vent(s) in another window. These models are best for homeowners who want to be able to move their model or who live in an apartment and want to be able to “lock” or shut their window during the day.

Types of AC Units Without the 6000 BTU Rating

Through the Wall

AC units with the through-the-wall type are more serious additions to a home and therefore tend to offer higher power ratings. Through the Wall AC units tend to be closer to 8,000 and 10,000 BTU on the low side and as high as 20,000 to 34,000 BTU.

RV Air Conditioner

An RV air conditioner needs to cool off the entire RV and therefore needs to have a much stronger BTU compared to smaller 6000 BTU units. RV air conditioners should be at least 13,500 BTU, but 15,000 BTU or 20,000 BTU units are better for larger RVs or RVs traveling to extremely hot places.

Mini Split

Mini-splits are two different systems (heating and cooling) in one unit. A mini-split unit can deliver heat to your home and air conditioning. These units are highly durable and last approximately 20 to 25 years. Mini-splits are powerful with 12,000 BTU to 21,000 BTU and can typically heat or cool several rooms at once.

Installing Small Window Air Conditioning Units

Installing small window air conditioning units is relatively easy and a process that every homeowner should be able to complete on their own. Each AC model has a detailed instruction manual online that can be found on the manufacturer’s website as well as a standard manual that comes in the box.

Start by finding a window close to an outlet where you can plug your AC’s power cord in. Then, open the window and install a weather strip if you have one. Weatherstrips can help keep the air inside and seal off small cracks.

Next, take the side panels of the AC unit and screw them into place. From here, you can insert the AC into the window and center it. Then close the window on top of the AC and screw in a bracket to keep the AC unit secure. After this step, slide the side panels out to reach the edges of the window or add the additional padding. Plug in your unit, and it is now ready to use.

Installing Small Portable Air Conditioning Units

Installing a small portable air conditioning unit is one of the most straightforward installation processes, and we recommend homeowners complete this installation on their own. A portable air conditioner will arrive pre-assembled.

First, if there are a few pieces that you need to attach to the unit, connect those. The provided instruction manual will share those steps. One piece that will need to be attached is the vent and its hose. Attach the hose to the AC unit and then to the vent panel.

Next, open your window and attach the vent panel to the window. Close the window to meet the panel and ensure that there are no air gaps present. Now, plug in the unit and turn it on.

Frequently Asked Questions

How many watts does a 6000 BTU air conditioner use?

Most 6,000 BTU air conditioners will use 560 watts of power. This typically will cool approximately 260 square feet. These units will also cost anywhere from $1.5 to $3 per day, depending on how many hours out of the day they are used.

What’s the difference between a 5000 and 6000 BTU AC?

The primary difference between a 5000 and 6000 BTU AC is the amount of space that they can properly cool. 6000 BTU is a more powerful AC and will cool off a slightly larger area. The 6000 BTU AC will also cost slightly more to run.

Which models on our list offer heating as well as cooling?

None of these models on this list offer heating as well as cooling. However, if you want to purchase an air conditioner system that can also provide heat, then you should purchase a mini-split unit or a combo unit like these. Mini-split units, such as Gree ACs, tend to start at a 12,000 BTU rating and can reach 21,000 to 24,000 BTU ratings.

What are some common problems that may arise with this sized unit?

The most common problem with a 6000 BTU air conditioner unit has to do with the placement. Most of these units are window air conditioner units and must be placed in the window. If the AC unit isn’t properly installed, there can be leaks that allow hot air to get in and therefore keep the unit from properly cooling the room. We have also seen problems with the AC not cooling because of a condenser or evaporator problem as well as water leaks from the base of the unit.

Where is the best place to buy this size air conditioner?

We recommend buying your 6000 BTU air conditioner from Amazon because of their affordable pricing, extensive selection, and quick shipping options. Home Depot, Lowe’s, and Best Buy are also options and offer a variety of 6000 air conditioning units for your home.


Air conditioning units can help homeowners beat the heat to keep homes cool and comfortable. The best 6000 BTU portable air conditioner on our list is the Danby Portable AC unit. If you want a window unit 6000 BTU air conditioner, however, then we recommend the  MIDEA MAW06R1BWT. Relax at home in a refreshingly cool environment with your new air conditioner unit.
