In the hot and humid climate of India, investing in an Air Conditioner becomes a blessing as it offers the benefits of maintaining humidity levels, cooling comfort, purification of air, and most importantly respite from the heat.
If you are in search of the detailed buying guide on how to calculate the Air Conditioner for your room, this blog is for you.
In this blog, we will understand the cooling capacity of an Air Conditioner in a room and choose the best AC that suits your requirements.
Before buying an Air Conditioner, apart from looking towards the different AC technology and brands, you need to calculate the size of the room and measure the space to choose the best AC based on the cooling capacity.
Once you calculate the room area, know the cooling capacity of AC required. The cooling capacity of an AC is calculated in British Thermal Units (BTU). In simple terms, the amount of heat converted into cool air by an Air Conditioner in a given time period is known as BTU.
Now, why is it important to understand the BTU chart while selecting the room AC?
If the BTU capacity is high for the given room size, it will fail to maintain the humidity levels making your skin feel clammy and sticky. Whereas, if it’s low then the room will not cool effectively. Hence, selecting the right AC with the standard BTU capacity is foremost.
Note that, 1 ton = 12000 BTUs per hour.
Let’s understand the method to calculate the estimated AC tonnage for a given room area.
Area Method to Calculate AC Tonnage:
Example 1: Length= 12 feet long, Width= 10 feet wide
Area = 12*10 = 120 sq. ft
AC Tonnage = (120/100) = 1.2
Choose an AC of 1.2 Tonnage
Volume Method to Calculate AC Tonnage:
Example 2: Length= 12 feet long, Width= 10 feet wide, Ceiling Height = 24 feet high
Volume= 12*10*24= 2880 cu. feet
AC Tonnage= (2880/1000) = 2.88 ≈ 3
Choose an AC of 3 Tonnage
Room Area ( Sq.ft) |
Cooling Capacity (BTU ) Per Hour |
|---|---|
|
Less than 90 sq. ft |
5000 BTU’s Note: AC Tonnage 0.5-0.8 |
|
90-110 sq.ft |
12000 BTU’s Note: AC Tonnage 1 |
|
120-150 sq.ft |
18000 BTU’s Note: AC Tonnage 1.5 |
|
150-220 sq. ft |
24000 BTU’s Note: Ac Tonnage 2 |
However, you can use the BTU calculator to gauge the estimated cooling capacity required for a particular room size or a house.
Do not miss to consider factors like ceiling-height of your room, window-size, the average temperature in your location that are responsible for the cooling effects of the Air Conditioner.
| Type | Description |
|---|---|
| Energy Efficiency | It is one of the qualifying factors we look up to before buying any electronic appliance. Here, energy efficiency means the capacity to save on energy consumption and hence the power bills. It is always recommended to buy a 5 stars AC and if not at least 3 stars, to save your pocket on high rates of power tariffs. |
| Auto-Cleaning | Buy the Air Conditioning system that works on an auto-cleaning mode and remove the allergic deposits within the blower. |
| HVAC Air Filters | Invest in the AC with air filters that inhibit dust particles, pollen, and other contaminants to maintain a Clean AC and quality airflow. It is necessary to enjoy a healthy cooling environment. |
| Dehumidifier System | The dehumidifier system controls the humidity in the air and allows clean air circulation within the room. It dehumidifies the air in monsoon and prevents it from getting damp. |
| Inverter-technology | In the Inverter AC, the compressor works to reach the preset temperature of the thermostat but after that slows down to maintain the cool airflow. This way the inverter AC is heavy-duty and energy-efficient compared to the non-inverter technology. |
After studying all of these key pointers, selecting the right air conditioner for your room depends on your budget, room area, cooling technology, cooling capacity, and type of air conditioner.
Essentially there are three different types of air conditioners which are Window AC, Split AC, and a Portable AC. Window AC is composed of a single unit fixed into the window. A Split AC comprises a cooling unit and a compressor unit, one fixed into the room, and the other is installed outside the house. Whereas Portable AC is useful for rented places, a freestanding single unit model able to move from one corner to the other.

Nice information. I just prepared an Excel from the above information and decided the capacity for my room.
