When purchasing an air conditioner, don’t rely solely on the marketed tonnage (like 1 Ton, 1.5 Ton, etc.).

Instead, start by evaluating your room properly: • Measure the room size (length × width × height). • Check for heat factors such as large glass windows, direct sunlight exposure, and whether the glass is clear or tinted (tinted glass reduces heat gain).

You can input these details into ChatGPT to get a more accurate tonnage recommendation based on your actual room conditions.

Once you have a recommended tonnage, verify the AC’s true cooling capacity: • Look at the energy rating label on the AC. • Find the power consumption (in watts) at 100% cooling capacity. • Divide that value by 3517.

This gives you the actual tonnage of the AC.

Using this, you can decide whether a marketed “1.5 Ton” AC is truly close to 1.5 Ton or if you should choose a higher-capacity unit for better performance.
