Understanding BTU For Your AC

BTU stands for British Thermal Unit, which is used around the globe in reference to heating and cooling devices. However, BTU (British Thermal Unit) becomes very crucial when it comes to Daikin air conditioners as it helps you decide which AC you need to buy for your house. For example, you might get confused between a 12000 BTU or an 18000 BTU energy-saving split AC in BD.

Do not worry in case you are not familiar with the acronym. We will help you understand what it is and how it can be beneficial for your air conditioner selection process.

What Is BTU?

As mentioned above, BTU (British Thermal Unit) is a global unit used for heating and cooling devices. The technical definition of the unit is

“One BTU (British Thermal Unit) is the amount of energy required to increase the temperature of one pound of water by one degree Fahrenheit”

In short, the unit speaks about the heating or cooling capacity of a given device. Let’s see how it works for your Daikin air conditioner.


Air conditioners function by throwing the heat out of a specific area, hence, reducing the temperature. This is where BTUs or British Thermal Units come into the role. As these units are a measure of the energy required to change the temperature, they help calculate the cooling capacity of a Daikin air conditioner.

For example: If we talk about a 1-ton split AC, it has a capacity of removing 12000 BTUs (British Thermal Units) per hour. Similarly, a 1.5-ton Daikin air conditioner can remove 18000 BTUs (British Thermal Units) every hour, making it more powerful than the 12000 BTU (British Thermal Unit) variant. That is why you will find the 18000 BTU inverter split AC price In Bangladesh higher than that of a 12000 BTU AC.


Now that you know how BTUs or British Thermal Units work for Daikin air conditioners, you can explore the range and find the one most fit for your requirements. You can also consult the experts to see how many BTUs (British Thermal Units) your specific room/area will need to get efficient cooling.
