Best 12000 BTU Air Conditioner Guide

The temperatures hover around the mid-90s throughout the summer in my home region. So, being familiar with the best 12,000 BTU air conditioners has enabled me to stay cool and perform my daily activities normally despite sweltering temperatures.

These ACs don’t have a vast coverage range and are best used as a single-room cooling option. However, most models aren’t easily portable, so knowing where you want to install a one-ton AC makes the selection process easier.

In this article, I’ll cover the key aspects of choosing a 12,000 BTU air conditioner and help you select the best Best 12000 BTU Air Conditioner for your needs.

Bottom Line Up Front

I’m not wealthy enough to buy inexpensive ACs that last for a season or two before breaking down. Instead, I prefer getting a more expensive but reliable model that performs well throughout the year.

That’s why I recommend getting a 12,000 BTU air conditioner like DELLA 048-MS-12K2V-17S if you need a permanent heating and cooling source for your garage or living room.

A portable model such as Whynter Elite ARC-122DS is an excellent seasonal option you can easily put into storage after the summer ends.

The Most Popular 12,000 BTU AC Categories

I dedicate a lot of time to understanding the requirements of space I’d like to cool or heat while deciding which air conditioner type to choose. Some rooms in my home don’t have the necessary infrastructure to support certain AC models, as their windows might be too small or their walls too thin.

So, before exploring different AC categories, you must first check if the room where you want to place the unit has everything the AC requires to function properly. Afterward, you can use the information you gathered to choose a model from one of the following categories:

  • Window – Even though they don’t require professional installation, mounting these units on a window can be challenging. Even though some models have heating functions, most homeowners use these ACs during summer.
  • Mini-split – These systems are comprised of outdoor and wall-mounted indoor units connected by a lineset.
  • Portable – Simple installation process, compact design, and low power consumption are among the key characteristics of portable ACs.
  • Through-the-wall – The so-called built-in 12,000 BTU air conditioners are a reliable option for spaces in need of a permanent heating or cooling source.

Output and a Coverage Range of 12,000 BTU ACs

I don’t evaluate the space where the air conditioner should be located just because of the unit’s installation requirements. I use the room size to pinpoint the models powerful enough to adjust the temperature within a specific area.

So, I would only install a one-ton, or 12,000 BTU unit in 400 to 600sq/ft space because using an AC with this output in smaller or larger areas would increase its power consumption.

Top tip: Don’t install a 12,000 BTU air conditioner in an uninsulated space because it will draw a lot of power and struggle to maintain the temperature at the same level.

Also, you shouldn’t assume that all one-ton models have the same coverage range since portable or window models might struggle to keep a 600sq/ft space cool.

In addition, seemingly inconsequential factors, like the ceiling height or the number of windows in a room, can limit the unit’s range.

Heating and Cooling Efficiency

My monthly utility bill didn’t increase after installing a 12,000 BTU air conditioner in my home. The unit I selected needs less than 1kW to reach a specific temperature and around 300 Watts more to maintain it.

Most manufacturers include the efficiency rating in the model’s product description, so estimating its monthly power usage isn’t too difficult. The Seasonal Energy Efficiency Rating (SEER) shows you the AC’s maximum efficiency during the cooling season.

You should also pay attention to the following ratings:

  • EER – Energy Efficiency Ratio indicates how much power a 12,000 BTU AC needs to cool a room at 95F outdoor temperature.
  • HSPF – If you’re searching for units with a heating function, you should check each model’s Heating Seasonal Performance Factor.

Also, I suggest choosing an Energy Star-certified AC because these units draw less power than models that don’t have this certificate.

Standard Features of 12,000 BTU ACs

The list of functions these units offer varies slightly from model to model. Still, most portable, through-the-wall, window, or mini-split ACs have similar features that let you increase or decrease room temperature and dehumidify the air.

In addition, the Fan Only mode is a standard option on most models and you can use it to circulate the air in the room instead of cooling it. Sleep and Energy Saving modes that limit the unit’s power draw during certain hours are also common.

Top tip: Opting for a WiFi-enabled 12,000 BTU lets you control the temperature in your home even while you’re away. 

Portable and window AC usually have short power cords, which is why I always measure the distance between the location where I want to install a unit and the nearest power outlet to ensure I don’t have to use extension cords.

Although most 12,000 BTU models come with installation kits, I suggest checking if the unit you’d like to get arrives with the components you need to install it.


Maintenance and Cost

I can hardly stress enough how important it is to take proper care of your 12,000 BTU AC. Failing to clean or replace its air filter will limit its cooling or heating capacity, encourage mold and bacteria growth and allow dirt to accumulate on the unit’s components.

I replace the air filter on my AC unit before every cooling season and perform routine checks every few weeks to determine the right moment to install a new one. Doing so keeps my AC in excellent condition and extends its lifespan.

Moreover, I don’t have a self-evaporative AC, so I have to empty its drain pan to ensure it can function correctly. Prices of 12,000 BTU air conditioners depend on their type, list of features, and manufacturer.

Portable models are the least expensive option as their price ranges from $200 to $600. On the other hand, you may have to spend more than $1,000 to purchase and install a 12,000 BTU mini-split system.

Selection Criteria

I had to browse through the specifications of hundreds of 12,000 BTU air conditioners before I could decide which models to include in this guide. Hence, the output capacity wasn’t the only criterion I relied on during the selection process.

The model’s price, installation costs, and energy efficiency were among the criteria I utilized to pick suitable units for a wide array of contexts. Here are a few more parameters that helped me select the best 12,000 BTU air conditioners:

  • AC’s durability – I believe that the AC’s true value lies in its longevity, which is why all models in the final selection have high-quality components.
  • Range of options – Each model I listed in this guide offers a variety of features that ensure the user’s comfort.

Black & Decker BD12WT6

Black & Decker BD12WT6

You can only install the Black & Decker BD12WT6 on double-hung windows, so I suggest exploring other options if the space the AC is for has some other window type. Also, you must check if you can install this unit on windows wider than 36 inches.

Despite these downsides, I think this Black & Decker’s Energy Star-certified model offers excellent performance at a reasonable price. In addition to keeping the room temperature in the 62F to 86F range, the unit can dehumidify or circulate the air.

I love the variety of control options this WiFi-enabled model offers, as it allows users to adjust its settings on the built-in control panel, through the MideaAir app for Android and iOS devices or by issuing voice commands with Google Assistant and Amazon Alexa.


  • Unique U-shape enables users to open the window

12000 BTU Mini Split Ductless Air Conditioner

I think that the Air-Con BO7PP9L3S3 is one of the most durable mini-split models released in the last few years. The manufacturer offers a seven-year warranty for the outdoor compressor and a five-year warranty for all other parts of the system.

You can keep using this mini-split even when outdoor temperatures drop below zero or rise above 95F. Moreover, you can switch between Sleep, Fan, Swing, and I Feel modes or program the AC with a push of a button.
