How to Choose the Right BTU AC for Every Room Size in Kenya – BSM Air Conditioners Guide
When shopping for an air conditioner in Kenya, one of the most important decisions you’ll make is selecting the correct BTU rating for your space. BTU, or British Thermal Unit, measures how much cooling capacity an air conditioner has. If you pick an AC that’s too small, it won’t cool the room effectively. Too large, and it will waste energy, increase your electricity bill, and may lead to uncomfortable humidity levels.
At BSM Air Conditioners Kenya, we specialize in helping clients find the perfect AC unit based on room size, usage, and budget. We stock only genuine and efficient models from trusted global brands such as Midea, Bosch, and Gree—all tailored for the Kenyan climate.
✅ Why BTU Matters in Choosing an Air Conditioner
BTU determines how powerful your air conditioner is. The higher the BTU, the larger the space it can cool effectively. However, selecting a higher BTU than needed isn’t always better—it can lead to short cycling (frequent on/off operation), increased wear, and higher electricity consumption.
By matching your room size (in square meters) to the right BTU rating, you ensure optimal cooling, energy savings, and extended equipment life.
📏 Room Size vs. BTU Chart – What You Need to Know
Here’s a basic guide to help you match Kenyan room sizes to appropriate AC capacities:
| Room Size (sqm) | Recommended BTU | Suggested Areas |
|---|---|---|
| 9 – 15 sqm | 9,000 BTU | Bedrooms, small offices |
| 15 – 25 sqm | 12,000 BTU | Standard bedrooms, home offices |
| 25 – 35 sqm | 18,000 BTU | Living rooms, medium offices |
| 35 – 45 sqm | 24,000 BTU | Large sitting rooms, retail shops |
| 45 – 60 sqm | 30,000 BTU | Open-plan spaces, conference rooms |
| 60+ sqm | 36,000 BTU+ | Commercial halls, restaurants |
Tip: For rooms exposed to direct sunlight or with multiple appliances/occupants, consider going one level higher in BTU.
