How to Choose Cooling for Your Room Size

Choosing the Right Cooling for Your Room Size

Room size is one of the most important factors in choosing a cooling product. A product that is too small for your space will struggle to make a difference, while an oversized unit may be unnecessary.

General Guidelines

Room Size Recommended Product Why
Under 10 m² Personal cooler or small tower fan Small spaces need less airflow; personal coolers are compact and efficient
10-20 m² Evaporative cooler or tower fan Good for personal comfort and air circulation without needing a window hose
20-30 m² Portable AC (9000 BTU) Refrigerated cooling needed for noticeable temperature reduction
30-40 m² Portable AC (12000 BTU) Higher capacity for larger or warmer rooms
Over 40 m² Portable AC (14000 BTU) or multiple units Commercial-grade cooling for large or open-plan spaces

Other Factors to Consider

  • Ceiling height: High ceilings increase the effective volume of the room
  • Insulation: Well-insulated rooms retain cool air better
  • Sunlight exposure: South-facing rooms may need more cooling capacity
  • Window access: Portable ACs need a window for the exhaust hose
