How to Use the AC Tonnage Calculator?

Choosing the right AC size for your room is now easier than ever. Simply follow these 4 easy steps to get an accurate recommendation:

• Step 1: Set Room Dimensions: Use the sliders to adjust the Length and Width of your room in feet. The tool will automatically calculate the total square footage.
• Step 2: Ceiling Height: Select your ceiling height (the standard height for most Indian homes is 10 feet).
• Step 3: Sunlight Exposure: This is crucial for cities like Prayagraj and Kanpur. If your room gets direct sunlight during the afternoon, select ‘High’ or ‘Very High’.
• Step 4: Number of Occupants: Enter the average number of people usually present in the room. Each person adds to the heat load.

Why Choosing the Right Tonnage is Critical?

If you install an undersized AC (e.g., a 1.0 Ton AC in a large hall), it will run continuously without cooling effectively, leading to massive electricity bills and potential compressor failure. Conversely, an oversized AC will cycle on and off too frequently, failing to remove humidity properly. Our tool is optimized for the extreme North Indian summer to give you the most reliable advice.

Quick Reference Guide for AC Buying:

• 100-150 Sq Ft: 1.0 Ton AC is enough.
• 150-250 Sq Ft: 1.5 Ton AC is recommended.
• Above 250 Sq Ft: 2.0 Ton AC or two 1.0 Ton units.
