How to Choose the Right Split Air Conditioner for Your Space

✅ The Ideal BTU for Every Room Size

To achieve efficient cooling, you need to choose the right AC capacity (BTU) based on your room's square meter size and ceiling height.

AC Capacity (BTU) Recommended Area Common Use
12,000 BTU (1 Ton) 12 - 18 m² Small bedroom or office
18,000 BTU (1.5 Ton) 18 - 25 m² Large bedroom or small living room
24,000 BTU (2 Ton) 25 - 35 m² Living rooms or majlis
30,000+ BTU 35 - 50 m² Open spaces or large areas

Note: For rooms with high ceilings or direct sun exposure, increase capacity by 10–20%.


⚡️ Factors That Affect AC Performance

🔹 Factors That Improve Efficiency:

  • Proper insulation in walls and ceilings

  • Thick curtains to block sunlight

  • Energy-efficient lighting

  • Installing the AC in a central and open wall area

🔸 Factors That Reduce Cooling Efficiency:

  • Large windows with no shades or insulation

  • High number of people in the room

  • Multiple heat-generating appliances (PCs, ovens)

  • Dirty filters and poor maintenance


🛠 Choosing the Right Split AC Based on Usage

🏠 For Homes:

  • Go for inverter ACs if used frequently (saves energy)

  • Ensure local warranty and after-sales service

  • Match BTU capacity to the actual size of each room

🏢 For Offices:

  • Choose low-noise models for better focus

  • Use multiple units for large, open spaces

  • Always check the Energy Efficiency Ratio (EER)
