Energy Efficiency

Considering all the possible ACs that we have tested, LG has a rating of 3 Star to 5 Star in energy consumption and ISEER of 4.0 to 5.25. At the same time, Panasonic ACs are of 3 Star to 5 Star and ISEER is between 4.0-5.20.

In case you want the most efficient one, LG 1 Ton 5 Star with ISEER 5.25 will be a better choice, however, in case you want to be more connected and efficient at the same time, Panasonic 5 Star models will be the better choice.

The details of each AC are checked in the table below.

Uncertain about the energy rating required? The two key factors that determine your perfect AC energy efficiency are the hours of use and the cost of electricity. At the correct energy rating, you will save a lot of electricity bill and still have the best cooling.

Homes that have a high use of AC or have high electricity rates are likely to enjoy 5 Star ratings. Comparatively, 3 Star or 4 Star ratings can be more economical to moderate users or those with lower electricity bills.

Performance Tests

This is a comparison of 4 LG ACs and 4 Panasonic ACs.

To be consistent and easy to understand, we have picked two of the popular models of each brand and pitted them against each other in a head to head battle.

The following table indicates the overall scores and the scores of the individual testing categories.

The second table presents the data of every test which we analyse. This data is used to compare each AC to other ACs in the brand and also to compare with the 150+ ACs that we have tested so far.

Cooling Performance Test

In terms of cooling performance, LG and Panasonic have a high cooling capacity and high-capacity compressors and high-capacity airflow technology.

The table below will show how each AC performs in terms of cooling.

The mean cooling marks of all the ACs tested so far are 8.8.

Of the four ACs that were tested, the LG 1.5 Ton 5 Star had the highest rating of 10/10 on cooling performance, and Panasonic 1.5 Ton 5 Star was closely behind at 9.5/10.

The LG models have VIRAAT Mode that is used to cool the device fast whereas the Panasonic models have Powerful Mode that cools the device quickly.

Both 5 Star models are able to work effectively to 55°C ambient temperature, and thus can be used in the extreme Indian summers. Panasonic 3 Star model has a slightly low maximum operating temperature of 52°C.

Energy Consumption Test

LG and Panasonic are both very efficient in terms of energy consumption, although the differences in yearly consumption rates are significant.

The comparison of each AC in terms of energy consumption is shown in the table below.

The overall energy efficiency score of all the ACs that have been tested so far is 8.5.

The 5 Star models of LG and Panasonic have the same ISEER values of 5.20, which is the best in the industry. Nonetheless, the LG 1.5 Ton 5 Star uses a bit less energy per year (744.75 kWh as compared to 759.55 kWh).

There is a greater difference in the 3 Star models with LG using 852.44 kWh per year as compared to 977.59 kWh in Panasonic. This amounts to about 1000-1500 of yearly electricity savings at LG.

Both brands have the dual inverter or variable speed compressor technology, which varies the cooling capacity according to the heat load, thereby improving the overall efficiency.

Noise Level Test

LG has less noise than Panasonic with an average noise of 27.5 dB in the brand indoors. In comparison, Panasonic brand average is 36 dB in case of indoor units.

The table below shows the comparison of each AC concerning noise.

The overall noise rating of all ACs that have been tested so far is 8.6.

As stated above, the two LG models had a higher score than 9.0 on low noise levels. LG 1.5 Ton 3 Star is especially impressive with the indoor operation of 26 dB, which is almost silent when the device is used normally.

The levels of indoor noise in both Panasonic models used in this comparison are higher, 34 dB in the case of the 5 Star model and 38 dB in the case of the 3 Star model. Nonetheless, Panasonic outdoor units have a lower noise level of 53 dB than LG 55-56 dB.

In the case of bedrooms or noise sensitive places, LG would be more suitable. In the issue of noise in the outdoors in apartment complexes, Panasonic might be a little ahead.

Air Quality Test

Panasonic leads in air quality, which is due to its high PM 0.1 filtration. LG provides HD Philtre with Anti-Virus Protection that is also efficient but traps a bit bigger particles.

See the table below to compare the performance of each AC in terms of air quality.

The mean score of air quality of all the ACs that have been tested so far is 8.4.

The PM 0.1 Philtre of Panasonic has the capacity to trap dusts less than 0.1 microns and therefore it is very useful in trapping dusts, allergens and pollutants. Moreover, the Crystal Clean technology offers self-cleaning capabilities to the evaporator coils to ensure that the quality of air and efficiency are preserved in the long run.

The HD Philtre with Anti-Virus Protection by LG provides a good defence against usual allergens and viruses. The Ocean Black Protection coating does not allow rust and corrosion, which indirectly protects the quality of air by keeping internal parts clean.

Panasonic has a better filtration, which is why it is the best option to users in a highly polluted environment or those with respiratory sensitivities.

Smart Features Test

Panasonic is a clear winner in the smart connectivity, with the first Matter-enabled AC in India, Wi-Fi controlled, voice assistant compatible, and True AI mode.

See the table below to compare each AC in terms of smart features.

The mean score of smart features of all the ACs that have been tested so far is 7.5.

The Panasonic 1.5 Ton 5 Star Premium Wi-Fi Inverter is the first Matter-enabled room AC in India, and therefore, it can work with Apple Home, Google Home, Amazon Alexa, and Samsung SmartThings using a single smart home standard.

True AI mode of Panasonic is based on Adaptive Thermal Comfort Model, which adjusts temperature and fan speed automatically, depending on the conditions in the room, weather, and preferences of the user, to optimise comfort and energy consumption.

LG AI Convertible 6-in-1 is good in terms of manual flexibility, but has no remote connectivity. Panasonic is the obvious choice to really smart home integration.

Durability Test

Both LG and Panasonic have very good durability features and they have copper condensers and protective coating against the Indian climate.

See the table below to find the comparison of each AC in terms of durability.

The mean score of durability of all the ACs that have been tested so far is 8.7.

The Ocean Black Protection coating of LG is specifically developed to resist salt, industrial smoke, and sand, which is why it is suitable in the coastal and industrial regions. The Gold Fin+ coating also increases the corrosion resistance and heat exchange.

The ShieldBlu+ protection coating used by Panasonic prevents leakages of refrigerant and increases the lifespan of heat exchangers. The two brands have 100 percent copper tubing that has superior heat transfer and less maintenance compared to aluminium.

Among the voltage stability, the 5 Star model of Panasonic has the greatest voltage range (100 V-290 V) whereas LG models are within 120 V-290 V. This renders Panasonic a little more appropriate in places where the voltage is highly unstable.

LG Vs Panasonic Inverter AC – Company

It is not always a matter of LG vs. Panasonic but also the brand itself, which is behind the product. Among the two brands, Panasonic has a much higher company score, with a longer comprehensive warranty of 5 years than that of LG, 1 year.

The compressor warranty of the two brands is the same 10 years.

The table below will show how each brand ranks in terms of company policies.

LG vs PanasonicInverter Split AC

VS

On average, the comprehensive warranty is 2 years and the compressor warranty is 10 years across 50+ AC brands tested to date.

The 5-year warranty of Panasonic is on PCB, coils and motors which is much better than the 1-year warranty of LG. This long warranty gives confidence and minimises the ownership expenses in the long run.

The two brands also have a strong network of services throughout India, which can be easily contacted in case of need. LG has a minor advantage in the availability of service centres in smaller cities whereas Panasonic has better warranty conditions.
