Which Brand Should You Buy?
Buy LG If…
- Smart home integration matters — LG ThinQ is the best AI-powered AC app in India
- You want the highest ISEER in a non-Japanese brand (5.30 beats most rivals)
- You’re in an area with temperatures above 50°C — LG’s 52°C rating matches Voltas
Buy Voltas If…
- You want India’s most popular brand with the widest parts availability
- Value for money is the priority — great 5-star inverter at ₹8,000 less than LG
- You need strong cooling in 48°C+ summers — Voltas is purpose-built for India
Buy O General If…
- Budget is not the constraint and you want the quietest, most efficient AC (22 dB)
- You’re buying a 1.5T or 2T for a master bedroom where noise matters
- Long-term electricity savings are more important than upfront cost
Buy Blue Star If…
- You’re in a Tier-2 or Tier-3 city — Blue Star’s 2,700+ service centres are unmatched
- You want a self-clean filter on every model, not just premium ones
- Budget is tight but you still want 5-star efficiency
Buy Godrej If…
- This is a second AC for a smaller room and budget is the #1 priority
- You want a reliable Indian brand with basic 5-star inverter at the lowest price
- You don’t need smart features or exceptional ISEER — just efficient cooling
