How to Choose the Right Inverter AC Size for Your Room in Bangladesh
One of the most common mistakes buyers make when shopping for an air conditioner in Bangladesh is picking a tonnage based on budget alone rather than room size. An undersized AC struggles to cool a large room and runs constantly, pushing your electricity bill up. An oversized unit cools too quickly without properly removing humidity, leaving the room feeling clammy.
A Quick Tonnage Guide
- Up to 120 sq ft: 1.0 Ton is usually sufficient.
- 120–180 sq ft: 1.5 Ton is the most common choice for Bangladeshi bedrooms and living rooms.
- 180–250 sq ft: 2.0 Ton or higher, especially for west-facing rooms that get direct afternoon sun.
Why Inverter Technology Matters
Inverter ACs adjust compressor speed instead of switching fully on and off, which means steadier temperatures and lower electricity consumption — often 30–50% less than non-inverter models over a full season. Most of the ACs we stock, from Hisense, Haier, Gree and Daikin, use full DC inverter compressors for exactly this reason.
Don't Forget Installation
Even the right-sized AC underperforms with poor installation — outdoor unit placement, pipe length and proper gas charging all affect cooling efficiency. Trizone Bangladesh includes free standard installation inside Dhaka city on every split AC purchase.
