What is your room size?
The first step in determining the size of the Air Conditioner you need is to calculate the square footage of the living space that you want to cool. This includes all of the rooms in your home that you use regularly, such as bedrooms, living rooms, and kitchens. To calculate the square footage, simply multiply the length of the room by the width. For example, if a room is 12 feet long and 12 feet wide, the square footage would be 144 square feet.

How many windows and open spaces are there in your room?
Once you have determined the square footage of the living space, you need to consider the number of windows and the amount of insulation in your home. Windows let in a significant amount of heat, so a home with many windows will require a larger air conditioner. Similarly, insulation helps to keep your home cool, so a home with good insulation will require a smaller unit.
Like if you have wooden windows It helps to keep your room cooler for a longer period. Also, there may be ventilators in a room which count as an open space though it is small It can reduce the cooling capacity of your air conditioner so make sure to seal them once you have fitted the air conditioner.

How is the climate of the area you live in?
The next step is to consider the climate in which you live. The climate plays a significant role in determining the size of the air conditioner you need. For example, if you live in a hot and humid climate, you will need a larger unit than if you live in a milder climate. Similarly, if you live in an area with high heat loads, such as near a factory or in a city, you will need a larger unit. In conditions like India as we have said earlier, it is very hot and humid and Loo’s(heat waves during summer) is a common thing. To fight that we need air conditioners with higher capacity than the other part of the world.

How to measure the BTU Cooling Capacity needed for your room?
Now that you have considered all of the factors that go into determining the size of the air conditioner you need, you can use a BTU (British Thermal Unit) calculator to determine the exact size of the unit. BTU is a measure of the cooling power of an air conditioner, and the calculator will take into account the square footage of your home, the number of windows, the amount of insulation, the climate, and the number of people in your home to give you a precise BTU rating for your air conditioner. Here is the link for the BTU calculator. You can visit the website and enter the details of your room to get accurate results.
As the weather in India is hot and humid during summer and heat waves are a normal thing we need ACs with a bit of extra cooling capacity so that they can cool efficiently and quickly. A 1-ton air conditioner means it has a cooling capacity of 12000 BTU, 1.5 tons has 18000 BTU and 2 tons has a cooling capacity of 24000 BTU and like that it goes on. Hopefully, you have understood the concept of BTU and how to use it, but don’t use it blindly as many other conditions are there.

Other Things To Consider
The final step is to consider the number of people who live in your home. The more people in your home, the more heat is generated, so you will need a larger air conditioner to keep up with the demand.
- For a small bedroom, home office, or guest room, look for an air conditioner with a capacity of 12000 BTU.
- To cool a bigger or busier room, you’ll want to step up to a midsized air conditioner rated at 16000 to 20000 BTU, but also watch out for noise.
- For a living room or family room, you’ll want a large air conditioner with 21000 to 26000 BTU, especially if you have an open floor plan
When it comes to selecting the right size air conditioner for your home, it’s important to consider all of the factors that go into determining the size of the unit. By taking the time to calculate the square footage of your home, the number of windows, the amount of insulation, the climate, and the number of people in your home, you can ensure that you select a unit that will cool your home efficiently and save you money on your energy bills.
A too much big air conditioner that your room needed for optimized cooling is also not beneficial. While a larger unit costs more and consumes more electricity if it does not run long enough the area maybe get cool but the air may still remain humid as an air conditioner also extracts moisture from the air.
In conclusion, when it comes to calculating the right size air conditioner for your home, you should take into account the square footage of your living space, the number of windows and insulation, the climate and the number of people in your home. The key is to choose the right size air conditioner that will provide the best balance between cooling efficiency and energy efficiency. It is important to consult a professional HVAC contractor to get an accurate measurement of the air conditioning unit that will best fit your home.
