🔥 1. Cooling Performance — Who Handles Heat Better?
When it comes to cooling, both models offer impressive results. However, they behave differently under specific conditions.
Blue Star 1.5 Ton 3 Star
The Blue Star 1.5 Ton 3 Star AC is widely known for its powerful compressor and fast pull-down cooling. Even in higher temperatures, it maintains stable cooling without dropping performance. This makes it ideal for Indian summers, especially in cities where heat becomes unbearable.
LG 1.5 Ton Inverter Split AC
The LG inverter model shines in consistent cooling. It maintains room temperature beautifully without fluctuations. Because LG uses dual inverter technology, the compressor operates smoothly and avoids sudden energy spikes. The cooling feels natural and extremely comfortable.
⭐ Cooling Winner: Tie
However, Blue Star has a slight edge during peak heat, while LG performs more consistently in everyday conditions.
🔥 2. Energy Efficiency — Who Saves More Electricity?
Although both ACs are inverter-based, their real-world electricity usage differs.
Blue Star
The Blue Star 1.5 Ton 3 Star offers balanced power consumption. It is neither too high nor aggressively low. Over months of use, the consumption stays predictable. This stability works well for users who want comfort without worrying about unusual spikes.
LG
LG’s inverter technology stands out. Because of its dual-rotary system, it consumes noticeably less power over long cycles. Moreover, it adjusts intelligently during nighttime, which further improves efficiency.
