Best 1.5 ton 3 star window ACs in India

To beat the summer heat, some of you may be planning to buy window air conditioners. They are often easier to install than split ACs, especially in rented homes where drilling walls or mounting outdoor units may not be practical. Since the compressor and indoor unit are present within a single chassis, installation costs and hassle are usually lower. Their servicing can be simpler. However, since their compressor sits closer to the room, they can be noisier than split ACs. Needless to say, they also require a suitable window or wall opening and would occupy more visible space. Provided you have that, you can consider one of the window ACs listed here. We have picked five 1.5-ton, 3-star window ACs from major brands available in India. These are all 2026 models, and you can find their specifications and pricing details. We have not tested these products, and they are the top options from Amazon India, arranged from highest to lowest price.

LG AW-Q18WUXA

Price: Rs 38,499

The LG AW-Q18WUXA uses LG’s Dual Inverter compressor technology, which employs a twin-rotary design. This is said to offer efficient performance without much vibration. The rated noise is 44 dB, making it one of the quieter options in this category.

The AC comes with convertible 4-in-1 cooling, allowing you to operate it at different capacity levels depending on the cooling requirements of the room. LG also uses a Top Air Discharge design that directs cooled air upward, which is then circulated through the room.

This is a non-Wi-Fi model.

LG claims an ISEER rating of 3.40 W/W. The warranty includes one year on the product, five years on PCB and motor components, and ten years on the compressor. It sports Ocean Black Protection coating on the copper condenser coils for improved corrosion resistance.

Panasonic CW-LU183CG

Price: Rs 35,490

Panasonic’s CW-LU183CG has an 8-in-1 convertible cooling, which means the inverter compressor can adjust cooling capacity across multiple operating modes based on room conditions and energy-saving requirements.

It is equipped with a PM 0.1 filter to capture finer airborne particles than conventional dust filters.

The AC uses 100% copper tubing with Panasonic’s Shield Blu anti-corrosion coating and is rated to operate in ambient temperatures up to 50°C. The company claims an ISEER rating of 3.45 W/W, which is among the highest in this comparison.

The unit supports stabiliser-free operation between 145V and 280V and carries a one-year comprehensive warranty and ten years on the compressor.

Lloyd GLW18D3LGSPR

Price: Rs 33,500

The Lloyd GLW18D3LGSPR uses a fixed-speed compressor rather than inverter technology. The compressor operates at full capacity until the target temperature is achieved. Then, it will switch off completely.

While inverter ACs generally deliver better seasonal efficiency, fixed-speed systems have a simpler design with fewer electronic components, and their repairs can sometimes be less complicated and less expensive.

The AC features a 100% copper condenser with Blue Fin protective coatings. Other features include Turbo Cool mode, Auto Air Swing, dehumidification mode, auto restart after power cuts, and operation in high ambient temperatures.

The model carries an ISEER rating of 3.40 W/W and comes with a one-year comprehensive warranty plus five years on the components, including PCB.

Voltas 183INV PEARL

Price: Rs 32,979

The Voltas 183INV PEARL brings inverter technology to the window AC segment at a relatively accessible price point. It uses a BLDC rotary inverter compressor that adjusts output according to cooling demand rather than cycling fully on and off.

The AC offers 2-in-1 adjustable cooling modes, an anti-dust filter, sleep mode, auto restart functionality, and two-way air swing. Voltas rates the unit for operation in ambient temperatures up to 50°C.

One area where the Voltas stands out is voltage tolerance. It supports stabiliser-free operation across a wide 110V to 285V range, which may be useful in areas where power fluctuations are common.

The unit carries an ISEER rating of 3.30 W/W. Warranty coverage includes one year of comprehensive, five years on the PCB and ten years on the compressor.

Whirlpool W6O2PP0

Price: Rs 30,200

The Whirlpool W6O2PP0 is the most affordable model in this comparison while still offering inverter technology. It features a 4-in-1 convertible cooling system that allows users to adjust cooling output according to room requirements.

Whirlpool claims an ISEER rating of 3.45 W/W, matching the Panasonic model and placing it among the most efficient units in this group. The AC uses a copper condenser with an anti-rust coating and incorporates the company’s 6th Sense technology for automatic performance adjustments.

Additional features include Auto Clean functionality to help reduce moisture buildup on internal components and stabiliser-free operation between 140V and 280V.

Whirlpool specifies a noise level of 32 dB, making it one of the quieter models. While the compressor is covered for five years, PCB coverage is limited to one year.

You may pick any of these models based on your requirements and budget.
