Similarities of LG and Samsung AC

Though LG and Samsung take divergent approaches to air conditioning, their flagship 1.5 ton offerings have a few core similarities:

01. Inverter Compressor

Both utilize inverter compressor technology for variable speed cooling based on heat load. This enables more consistent temperatures and increased energy efficiency versus traditional fixed-speed ACs.

02. Capacity

The 1.5 ton capacity of both models is ideal for room sizes of 111 to 150 square feet. Their cooling should sufficiently handle these medium-sized spaces.

03. Copper Condenser Coil

Copper condenser coils enhance durability while requiring less maintenance than aluminum coils over time. This is a plus for the lifespans of both ACs.

04. Ambient Temperature

These LG and Samsung ACs can operate in peak ambient temperatures up to 52°C – suitable for most Indian summers.

05. Remote Control Functionality

The included remote controls allow easy access to all modes, fan speeds, timers and other functions. This saves having to manually adjust settings on the AC unit itself.

06. Air Filtration

Air filtration is a strength of both brands. LG’s HD filter provides anti-virus protection, while Samsung’s copper filter has anti-bacterial properties. Clean air is assured with either pick.

07. Self-Diagnosis

Both models include self-diagnosis features that alert users to any technical issues and can simplify maintenance. LG’s Smart Diagnosis and Samsung’s Auto Clean functions are examples of this.

Differences Between LG and Samsung

While the two brands share some core DNA, there are also notable differences that set them apart:

Energy Efficiency

Energy efficiency testing gives LG the edge here. Its higher EER and ISEER ratings translate to greater savings on electricity bills in the long run.

Noise Level

Noise level is another LG strong suit. Its operating volume measured in decibels (dB) runs quieter than Samsung equivalents, especially on higher fan speeds.


This is one area where Samsung falls short. LG offers WiFi control through its ThinQ apps, whereas Samsung lacks smart connectivity features.

Stabilizer-Free Operation

LG ACs can operate over a wider voltage range of 120V-290V without needing a stabilizer. Samsung’s working voltage range is narrower at around 135V-290V by comparison.


The Indian Seasonal Energy Efficiency Ratio (ISEER) reflects real-world efficiency accounting for climate. LG again wins out with a higher ISEER value of 5.2 vs 5.16 for Samsung.

Sleep Mode

LG’s smart AI-powered sleep mode optimizes cooling and power usage overnight when demand is lower. Samsung still lacks an adaptive sleep mode.

LED Display and Temperature Display

LG displays both temperature values and settings on its LED display. Samsung’s minimalist LED panel omits the temperature readout.

Cooling Modes

Cooling modes like LG’s Monsoon Comfort give added flexibility. Samsung has fewer specialty modes, though both offer basics like auto, cool, fan, dry, etc.

Cooling Comparison

The nitty gritty of any AC is its cooling performance. Here’s how LG and Samsung compare:

  • BTU cooling capacity is nearly identical, indicating similar potential for heat removal.
  • Airflow in cubic feet per minute (CFM) is comparable, so comfort levels should be on par.
  • Field tests confirm both can effectively cool rooms down 20°F+ even in extreme 110°F+ heat.
  • LG edges out Samsung at the highest fan speeds for rapid turbo cooling.
  • For most use cases, real-world cooling should be equivalent based on motor power and design.

Verdict: Draw for cooling, with a slight advantage to LG.

Noise Comparison

Noise level could be a key decider if you desire whisper-quiet operation.

  • At low and medium fan speeds, both brands operate at normal conversation levels around 30 -35 dB.
  • LG maintains this gentle hum even on turbo mode, while Samsung gets louder.
  • Compressor noise is also muted on LG models compared to light pulsating sounds on Samsung.
  • Overall, LG ACs live up to their Quiet Cooling claims at 2-3 dB quieter across functions.

Verdict: LG is the quieter split AC option.

Energy Efficiency Comparison

For long-term savings on utility bills, energy efficiency matters.

Star Rating55
Annual Power Consumption744.99 Units Per Year749.48 Units Per Year

Key Takeaways:

  • Both meet 5 star BEE criteria for efficiency.
  • However, LG’s higher ISEER rating showcases superiority in real-world conditions.
  • The annual kWh used is marginally lower for LG models.
  • Advanced features like LG’s Dual Inverter boost efficiency further.

Either of these units will provide enough cooling capacity for 150 square feet without shortage. However, LG’s higher airflow CFM and flexible mode options give it another slight edge. Ultimately, it comes down to preference.

Maintenance Comparison

On maintenance fronts, both brands simplify upkeep:

  • Self-cleaning functions reduce manual cleaning needs.
  • Long-lasting copper coils resist corrosion and damage.
  • Removable, washable filters can be easily cleaned.

LG’s Ocean Black Protection further shields its condenser from environmental contaminants like dust and salt.

the maintenance demands are very comparable between LG and Samsung for these models. No clear winner.

Better choice between LG and Samsung 1.5 Ton?

Okay, for the question of a million dollars – which brand provides the best split AC of 1.5 ton overall?

LG’s strengths:

  • Lower energy costs – it can be as much as a couple of thousand rupees in a year.
