Whether you’re looking for a split AC tonnage calculator or wondering what size of 1.5 ton AC room size fits your villa, this guide breaks it all down. Living in Dubai’s intense heat? Choosing the right AC size is crucial. Whether you need a 1 ton AC, 1.5 ton AC, or want to know how much area will a 1.5 ton AC cover, this guide by airchill ac maintenance and duct cleaning explains it all—from AC calculation formulas to electricity cost insights.
📐 How Do You Calculate AC Tonnage for Your Room?
To figure out the right AC size, use this formula:
Room Area (sq. ft) × 20 ÷ 12,000 = Tonnage
This simple AC calculation formula helps you size your air conditioner correctly based on your space. It’s the base of every AC tonnage calculator per square foot, especially in heat-intensive regions like Dubai.
Example:
- A 12×12 room = 144 sq. ft
- 144 × 20 = 2,880 BTUs
- 2,880 ÷ 12,000 = 0.24 tons, so a 1 ton AC is ideal
✅ Is 1 ton AC enough for 12X12?
Yes, absolutely—it’s a perfect match.
🏠 What Size Room is Needed for 1.5 Ton AC?
How much area will a 1.5 ton AC cover? Around 150–200 sq. ft, depending on sunlight and insulation.
