Air Conditioners Buying Guide for Nigerian Homes

Split and window units differ in noise, installation, and efficiency. Correct tonnage and inverter technology matter most in Nigerian homes — undersized ACs never catch up; oversized units leave humidity high.

Room tonnage guide

• Up to 12 m² (small bedroom) → 0.75–1 ton (9,000–12,000 BTU)
• 12–18 m² (standard bedroom) → 1–1.5 ton
• 18–25 m² (large bedroom / small living room) → 1.5–2 ton
• 25–35 m² (living room) → 2–2.5 ton
• 35 m²+ → 2.5 ton+ or multiple units

Add 10–20% capacity for west-facing windows, top-floor flats, or ceilings above 3 m.

Split vs window AC

Split AC: quieter indoor unit, better for bedrooms, requires professional installation — preferred for long-term home use.
Window AC: single unit, easier retrofit, noisier, often lower purchase price — good for rentals and budget cooling.

Why inverter AC pays off

• 30–50% lower electricity use in typical nightly use
• Lower startup surge — friendlier to 3.5–5 kVA generators
• Quieter operation for bedrooms
• More even cooling in humid southern climates

Power planning

A 1.5-ton inverter AC may draw 1.2–1.8 kW running and 2.5 kW+ at startup. Size your generator or inverter backup accordingly. Clean filters often during dusty season.
