Air Conditioner Tonnage Calculator – Choosing the right size of AC is the most important step before installation. A small AC will create problems in cooling your space, while a big AC will consume excess electricity and will be switched on and off frequently, reducing our comfort. To solve this problem we have created air conditioner tonnage calculator – a free and easy to use online tool that will help you estimate the cooling capacity.
Our calculator considers factors like room (length × width × height), number of people, heat load from appliances, windows, doors, direct sunlight and insulation quality as inputs and quickly estimates required cooling both tons or Refrigeration (TR) and BTU/hr giving you an idea of which AC capacity is best for you is best.
Why is Tonnage Calculation Important?
Many people just estimate the room area or such while buying an AC, which is a mistake. Cooling load depends on more than just the square footage.
For example, a small room that has large glass windows and is west facing will need more tonnage compared to a large but shaded room. Our calculator uses industry-based formulas to ensure accuracy and reliability.
Benefits of Using This Tool:
- Accurate Sizing: Prevents under-sizing and over-sizing of air conditioners.
- Energy Savings: The right AC tonnage reduces electricity consumption.
- Longer Life of AC: Proper load matching prevents unnecessary wear and tear.
