What Size of Air Conditioner Do I Need for My Room in Nairobi?
Expert Buying Guide from BSM Air Conditioners Kenya
Buy affordable air conditioners in Kenya with confidence—but sizing matters just as much as brand and price. Whether you’re furnishing an apartment in Nairobi’s Kilimani, outfitting a guest room in Ruiru, or installing climate control in your home office in Syokimau, getting the right air conditioner size ensures comfort, energy savings, and long-term reliability.
So if you’re wondering, “What size of air conditioner do I need for my room in Nairobi?”—this complete guide from BSM Air Conditioners, the official distributor of Midea air conditioners in Kenya, is for you.
🌤️ Why Sizing Your AC in Nairobi Matters
Nairobi’s climate is generally mild, but certain zones—especially west-facing apartments, glass-panelled offices, and densely populated flats—can get hot and humid. An undersized air conditioner will overwork and underperform, while an oversized unit will short-cycle, consume more electricity, and leave the room clammy.
BSM Air Conditioners offers free expert consultation and sizing assessments to help Nairobi residents select the most efficient unit for their space.
📏 How to Calculate the Right AC Size for Your Room
Air conditioner capacity is measured in BTUs (British Thermal Units). BTU determines how much heat the AC can remove from a room per hour.
✅ Quick Formula:
BTU = Room Size (in sq. ft) × 60 to 80
You can also convert square meters to square feet:
1 m² = 10.76 sq. ft
🔽 AC Sizing Reference Table
| Room Size (m²) | Room Size (sq. ft) | Recommended AC Size (BTU) | Suggested Midea AC Model |
|---|---|---|---|
| 9–14 m² | 100–150 | 5,000–6,000 | Midea 9000 BTU Wall Type |
| 15–23 m² | 160–250 | 9,000–12,000 | Midea 12000 BTU Wall Type |
| 24–30 m² | 260–320 | 12,000–15,000 | Midea 18000 BTU Wall Type |
| 30–40 m² | 320–430 | 18,000–24,000 | Midea 24000 BTU Inverter |
| 41–60 m² | 440–650 | 24,000–36,000 | Midea Floor Standing AC |
| 60+ m² | 700+ | 36,000–60,000+ | Ceiling Cassette / Ducted Units |
🧠 Tip: Add 10–15% more BTUs for west-facing rooms, high ceilings, kitchens, or rooms with many electronics.
