12000 BTU Air Conditioner Buying Guide

There is so much that you would need to consider or think about when you are looking to buy a 12000 BTU air conditioner, including what types there are and much more. This guide can help you decide what the features are that you want and what type of air conditioner you want. If you want to know more about purchasing the right model, then go ahead and keep reading on.

Types of 12000 BTU Air Conditioners

A few different types of 12000 BTU air conditioner models that you could choose from, including portable and window-based. If you are searching for something that you only need to install once you are using it and doesn’t require extra hoses, you should consider the window style. However, if you want to move the machine around your home or if you don’t need to worry about space, then you can think about the portable models for your home.

Features to Look for in a 12000 BTU Air Conditioner

Another thing that you must consider when you are looking to buy a new air conditioner is the features that your machine might have. Some of the top features that you want to have available on the device include:

  • Energy Efficiency Ratio (EER) – You need to find the machine that has the highest EER since this would mean it is more energy-efficient. This will be ideal if you want to cut down on your utility bill without compromising on the cooling.
  • Controls – Another thing to think about is the controls and how you will make the changes. Few ACs can operate using a smartphone application or even the remote control or the control panel on the machine itself.
  • Wi-Fi Enabled – Also, if you are trying to create a smart home, then you must have a machine that is Wi-Fi enabled. That would let you make all of the changes you would need to the settings without being home or near the machine.
  • Eco Mode – If you want to ensure that your air conditioner usage isn’t harming the environment, then you need to have one that has eco mode. This mode allows the machine to run more efficiently without using the highest cooling settings.
  • Remote – Whether it has a remote control or not is another big thing, so make sure to check this out. The remote control must be included so that you can make all of the setting changes without moving.
  • Noise Level – For those who would be using these in your bedroom or the office, you need to pick one that would be very quiet. It should be quiet on the highest level of operation and not just the lowest, so make sure to check this out.
  • Dehumidification – If you find a lot of moisture in the air, you might want to consider if the machine can be a dehumidifier. That would help make the air more comfortable, and you won’t have to invest in another device.
  • Heat Mode – The final factor and feature that you want to consider are whether it has the heating mode or not. That will be critical if you are in an area where it gets freezing and if you don’t have another heating system available.

Ensure that you know which of these features would work the best for you and which ones you need to have on your machine and which ones you can do without.

12000 BTU vs. 14000 BTU Air Conditioner

One of the main differences that you must know about when it comes to picking between a 14000 BTU and 12000 BTU ac model is the room size. This is the only major difference, and the 12000 BTU is perfect for a room of around 400 square feet. However, the 14000 BTU can handle a room of around 500 square feet, so make sure to consider this.

12000 BTU vs. 18000 BTU Air Conditioner

Also, if you are thinking about what BTU level you need for your home, you should consider the size of the room. The 18000 BTU model would be ideal for an area of 800 square feet up to 900 square feet, while the 12000 BTU is perfect for smaller areas. For example, the 12000 BTU one would be great for smaller apartments or homes of around 400 square feet.


  • How do I know what BTU level I would need?

When you are looking at air conditioners, the major criteria determining what BTU you are looking for is the room size. For example, if you are trying to cool down a bigger room, you want a higher BTU level, but the lower the room. This would ensure that the chosen model can effectively and easily cool the room without wasting energy.

  • What BTU level do I need if I plan to use the air conditioner for heating?

However, if you would be using the air conditioner as a regular heating unit for your home, you might want to go for a higher BTU level. This is because it isn’t going to be as powerful when it comes to the heating aspect, so you want something more forceful for this.

  • How do I decide what model is perfect for my home?

You need to consider a few things when trying to pick the right air conditioner for your home, including the price, the room size it can handle, and more. You also need to consider the type of machine you are looking at, how you can control it, and how easy it is to use and install.


Ensure that you are checking out all of these various models and deciding if you want the portable or window model. That would then narrow down your list, and then you should consider the features that you want. Don’t be afraid to look at these models and any others available and compare them before making your choice.
