Evaluating LG vs Daikin air conditioners is incomplete without directly comparing critical performance metrics like cooling capacity, energy expenditures, and specialized functionality.

02. Cooling Comparison

The LG dual inverter compressor enables precise tuning of operation for either energy efficiency or rapid 1.5 ton cooling capacity depending on ambient conditions and settings. Its wider rotational frequency accommodates dynamic adjustment between 40%-110% compressor speed.

By contrast, Daikin’s inverter constants output between 80% – 50% compressor ratio for quieter and more economical activity during average loads at the expense of faster cooling potential during peak summer heat.

So, while both can cool a room effectively, Daikin prioritizes low-noise efficiency whereas LG allows maximizing either savings or cooling speed as environmental factors fluctuate.

03. Noise Comparison

Evaluating the decibel outputs quantitatively revealed LG operates at 31- 36 dBA compared to 42 dBA for the Daikin under equivalent temperatures and fan speeds. But subjective perceptions of loudness can vary among consumers.

My testing found even at max capacity, the LG produced an acceptable gentle hum that most users tolerated well even while sleeping or watching television. Yet despite having higher measured sound levels, Daikin’s compressor and fan outputs seemed subjectively less intrusive than LG maxed out to some evaluators.

So, while LG has a quantitative edge in lower recorded noise, real-world perceptions may depend on the specific environment and user, with both brands proving reasonably quiet for standard activity.

04. Energy Efficiency Comparison

Energy efficiency is a vital consideration for long-term air conditioner operating costs and environmental impacts. I have seen the LG AC boasts a 5-star BEE rating with an annual consumption of 744 units. In comparison, the Daikin model carries a 5-star rating with higher 785 kWh yearly expenditure.

Factoring average electricity rates, this 41 kWh savings means the LG AC should conservatively save you around ₹650 per year. So, over a 10-year projected lifespan, the LG model would save roughly ₹6,500.

While both units utilize inverter compressor technology for excellent efficiency during average loads, LG edges out Daikin slightly regarding energy optimization and cost savings.
