- Capacity (Tonnage):
- 1.0 Ton: Optimal for small rooms up to ~120 sq ft.
- 1.5 Ton: Best for medium‑size rooms ~120–180 sq ft.
- Star Rating: A higher BEE star rating (5★ or 4★) typically means lower electricity bills — especially important if you use the AC for long hours daily.
- Inverter vs Fixed Speed:
- Inverter ACs adjust compressor speed for steady cooling and energy saving — often worth the slightly higher price.
- Fixed Speed ACs are budget‑friendlier but may consume more power and run noisier.
- Install & Maintenance: Always factor in installation cost and schedule yearly servicing to maintain peak performance and efficiency.
