Key Differences Between LG & Voltas Air Conditioners
Let’s compare some of the core factors that distinguish LG vs Voltas AC models:
Energy Efficiency
- LG currently offers 5 star rating ACs indicating high energy efficiency meeting 2024 regulations, Annual Energy Consumption: 744.99 Units Per Year. This makes LG units around 8-10% more efficient than equivalent Voltas models.
- On the flip side, Voltas highest range is 5 star with delivering decent cooling performance for the price, Annual Energy Consumption approx. 780.99 Units Per Year. Expect ~7% higher annual electricity bills over LG.
Noise Level
- LG 1.5 ton ACs operate very quietly, with indoor noise ranging from 31 dB to 36 dB in best models.
- Voltas has relatively louder 47 dB to 52 dB noise level, which is still an improvement from earlier models touching 55 db.
Connectivity
- Most premium LG split AC models come Wi-Fi enabled for connectivity. You can control and monitor AC with the LG ThinQ app from anywhere.
- Voltas ACs lack any smart connectivity or app control. You are limited to just the infrared or Bluetooth remote that comes along.
Stabilizer-Free Operation
- LG ACs delivers enhanced stabilizer-free operation within a wide input voltage fluctuation between 120V-290V. This ensures smooth working even with grid voltage ups and downs.
- Voltas 1.5 ton AC works without external stabilizer within a relatively narrow 110V-285V input voltage range. Power spikes beyond threshold will disrupt functioning.
ISEER Value
The Indian Seasonal Energy Efficiency Ratio or ISEER indicates the energy performance across a full year’s operation.
- Premium 5 star LG models have best-in-class ISEER of 5.0 translating into lower electricity costs for owners.
- Comparable Voltas ISEER is slightly lower at 4.65 for current year, with scope of further improvement to match LG.
Sleep Mode
Both LG and Voltas ACs have custom sleep modes that control temperature and airflow to give you comfortable sleep:
- LG sleep mode gradually increases set temperature up to 2°C in the first one hour. This prevents any sudden ambient change for sound sleep.
- Voltas sleep mode operation isn’t as clearly specified. It supposedly stops cooling 2 hours after activation for power saving.
LED/Temperature Display
- LG indoor units have a bright dual LED display + magic display to showcase temperature read-out, mode settings etc.
- Voltas indoor unit has simple LED indicators without a full-fledged display panel. You need to rely on remote for temperature and settings.
Cooling Modes
Both brands offer smart cooling customizations:
- LG AI Convertible 6-in-1 modes self-adjust between faster cooling, energy saving, dehumidification etc as needed.
- Voltas has 4-in-1 adjustment to manually select between 100% to 20% compressor speed if full capacity isn’t needed.
In-Depth Performance Comparison
Now that we’ve seen the general differences, let’s dive deeper into comparison parameters:
Cooling Capacity
Effective cooling depends on compressor technology, airflow and heat exchange efficiency of coils.
LG Dual Inverter Compressor variable-frequency operation outperforms Voltas rotary inverter on most metrics:
- 33% faster pull-down time
- Wider operating frequency for faster heat removal
- Low vibration and noise
On paper, Voltas offers competitive 1.5 ton models matching room cooling capacity under nameplate conditions. But LG wins hands down in real world performance thanks to technological superiority!
Noise Level Analysis
Noise rating gives a fair idea of disturbance during operation – lower numbers mean quieter performance.
Here LG 1.5 Ton ACs are much ahead, with lowest noise going down to just 31 dB in night operation as tested independently. 31-36 dB range is well below the 40 dB ambient noise of a quiet room without HVAC. You won’t even notice the indoor unit running!
In contract, equivalent Voltas AC indoor units are almost 15-20 dB louder mostly in the 45-48 dB range under medium fan settings. You will definitely hear the motor and airflow while sitting in the same room.
Energy Efficiency Comparison
Seasonal power consumption directly impacts annual electricity bills.
As highlighted earlier, 5 star LG models have 8-10% higher ISEER than comparable Voltas series. This translates into yearly savings of 500 to 800 units if you use the AC regularly in summer. That’s over ₹4000 to 6000 saving at avg. tariffs.
The advanced LG Dual Inverter compressor optimizes compression irrespective of outdoor temperature resulting in major efficiency gains in partial load conditions. Improved speed control eliminates temperature fluctuations and ensures low power draw.
Voltas 4-in-1 tonnage adjustment does help limit electricity use for small spaces. But LG auto-conversion modes work better since the compressor itself offers variable capacity.
Smart Features Comparison
Modern conveniences like app control and voice assistants integration is a key draw for buyers. Here LG AC models enjoy significant advantage:
- Most premium LG split ACs come Wi-Fi enabled for controlling AC with the LG ThinQ app. You get granular remote adjustments and scheduling flexibility.
- LG app also offers in-depth diagnosis while Voltas remote shows only basic trouble codes.
- LG app lets you control multiple home appliances like TV, washing machine etc. from the same dashboard!
- LG ACs also work with Amazon Alexa and Google Assistant letting you change modes, set temperature etc. via voice commands. Very convenient!
- Voltas app and smart features are still playing catch-up to LG. You need to be physically present to adjust settings on remote control.
Which perform better in 150 Square Feet Room?
A typical 150 sq ft bedroom in India would measure say 15 ft x 10 ft. Which AC is better suited for faster temperature pull-down and uniform cooling in that space?
LG 1.5 Ton 5 star Dual Inverter AC is recommended for such mid-size 150 square feet area:
- 33% faster cooling thanks to twin rotors in compressor
- 6-in-1 modes maintain desired temp uniformly across room
- 31-36 dB quiet operation won’t disturb sleep
Comparatively, Voltas compressor and airflow velocity may not effectively cover 150 sq ft room from corner to corner. Noise level is also much higher.
So if your priority is faster, noiseless cooling for restful sleep in addition to cost savings, then LG Dual Convertible AC is the winner here.
Voltas model would suffice if you simply want basic room cooling on a tight budget.
