Should you buy an inverter window AC or non-inverter window AC? Well! Inverter window ACs have various modes that maintain cooling. It saves power. But non-inverter ACs are different as they work on fixed speed.
- The average ISEER of inverter AC is 3.59, and of non-inverter AC is 3.35.

These are their power consumptions as per the star label. Power consumption is noted by operating ACs for 1600 hours under test conditions. This was the average ISEER and power consumption of the top 3 inverter and non-inverter ACs.
The difference in the power consumption of inverter window AC and non-inverter window is only 60 units. Is it worth buying an inverter window AC for a mere difference of 60 units?
Some Tips Before Making a Purchase
Star Ratings Star ratings have changed. Now all ACs with 3.5 or above ISEER are considered 5-star ACs. This rating is valid till December 2024. Both inverter and non-inverter ACs with 3.5 or more ISEER are 5-star rated now. Should you buy the best window AC 2023 or a split AC 2023? Split ACs are better than window ACs in terms of noise levels. Window ACs produce noise despite the presence of Styrofoam. The average noise levels of a window AC are 55dB. The noise levels of a washing machine are 60 dB. The average noise levels of split AC are 35dB. Hence, split ACs have the upper hand in terms of noise levels. Solution- If there is little space between indoor and outdoor units of AC, and if you have a big room, then buy split AC. Otherwise, you can also go for a window AC. Warranty Packages All window ACs have one year comprehensive and five years warranty on the compressor. But other parts can also be damaged. Therefore we strongly recommend you buy an extended warranty package. As per our analysis, you should buy Go Warranty. You can call them and get customized plans but make sure you keep your AC protected. Installation charges Brands charge around Rs 1000 as installation charges for window ACs. But they might tell you to buy a stabilizer from them to prevent damaging the warranty. It is not valid. We highly recommend you use a stabilizer. |

The best window AC 2023 is an LG 1.5-ton 5-star (2023) inverter AC with a 1.42-ton cooling capacity. Cooling capacity is good, considering it is a window category. It has 3.68 ISEER. The offline model has different cooling capacities and compressors than the online models.
You get a dual inverter compressor and convertible 4-in-1 modes (40% to 100% with AI mode).
Inverter AC can work as non-inverter AC by fixing their speed in 100% mode for 30 minutes. Then leave it on auto mode, i.e. AI mode. It’ll cool the walls first, then AI mode will maintain the cooling. This way, you save electricity and get good cooling.
It is the only AC with a 4-way air swing and ocean black protection. All ACs have some sort of coating. LG gives its famous ocean black protection, which is a chemical coating only. You get an HD filter with anti-virus protection. However, we can’t guarantee an anti-virus feature. The smart diagnosis feature is good. Noise levels are 44dB due to the dual inverter compressor. The two rotors work simultaneously to reduce noise levels- 44dB, which is good.
You get a one-year comprehensive, five years on PCB (essential in inverter AC), and a ten-year compressor warranty. It costs ₹ 41,000. It is a fair price.

Chemical Coatings:
- Bluestar and Lloyd call it Blue Fin Technology, as their chemical coating is blue.
- Voltas named it anti-corrosive coating as it is transparent.
However, they are the same. Their work is to protect condensers and fins from sediment and salt. However, condensers can still leak in coastal areas or near drains due to high fumes. With a coating, this leakage gets delayed.
Features:
All three window ACs have an excellent dust filter but not a PM 2.5 filter. They have Turbo Mode and Humidity Control feature, i.e. dry mode.
Difference:
Voltas lacks a self-diagnosis feature, whereas Lloyd and Bluestar have it. Self-diagnosis technology displays an error code in case of damage or an error. Just share that error code with the service team. They will understand the issue after reading the error code, leading to faster repairs.
Are the big claims valid?:
Brands claim cooling from 48°C to 52°C. We, however, could not check these ACs in such high temperatures. But the companies claim so.
They have noise levels ranging between 54 to 56 dB noise levels.
All three have one year comprehensive and five years warranty on the compressor, with two free services in the first year.
