Btu And Cooling Power
BTUstands for British Thermal Unit. It measures the cooling power of air conditioners. The higher the BTU, the more cooling power the unit has.
BTU affects how well an air conditioner can cool a room. A unit with too low BTU will not cool the space well. Too high BTU can waste energy and cause the room to feel cold and damp.
Choosing the right BTU depends on the room size. Use this simple guide:
| Room Size (sq ft) | Recommended BTU |
|---|---|
| 100 – 300 | 5,000 – 6,000 BTU |
| 300 – 500 | 7,000 – 8,000 BTU |
| 500 – 700 | 10,000 – 12,000 BTU |
| 700 – 1,000 | 14,000 – 15,000 BTU |
- Small rooms need lower BTU units.
- Larger rooms require higher BTU units.
- Check room size before buying a portable AC.
