Inverter vs non-inverter — choose inverter
Before brand, pick an inverter unit. Inverter aircons vary their compressor speed instead of switching fully on and off, so they use 30–50% less electricity and cool more evenly. The slightly higher upfront cost pays for itself quickly in SA's high-tariff environment.
Popular brands in South Africa
- Samsung & LG — premium, quiet, feature-rich (Wi-Fi, smart modes). Strong local support and parts availability.
- Daikin & Mitsubishi — top-tier reliability and efficiency, favoured for ducted systems. Higher price.
- Midea, Gree & Hisense — excellent value mid-range inverters; widely installed in SA homes.
- Alliance & Jet Air — budget-friendly, locally distributed, good for secondary rooms.
What actually matters more than brand
- Correct sizing. An oversized unit short-cycles and wastes power; an undersized one never cools. Sizing matters more than badge.
- Quality installation. A great unit installed badly (wrong gas charge, poor pipe insulation) underperforms. A SAQCC Gas-registered technician is non-negotiable.
- Energy rating. Check the CSPF/efficiency rating — higher is cheaper to run.
- Warranty & local parts. Choose a brand with SA distribution so warranty claims and spares are easy.
