Window ACs refer to ACs that are installed into the window of a room. They have only indoor units and are typically cheaper than split ACs. However, they require more power to run and this can impact your electricity bills. To combat this issue, companies have launched power-efficient window ACs with different power saving ratings – the more the rating, the higher the power efficiency. A 3-star window AC can strike the perfect balance between a power-efficient device and an affordable one. So, get yourself a 1.5-ton 3-star window AC for your medium room or large living room. Here are a few 1.5-ton 3-star window ACs available on Amazon. These have been listed based on their features.
The LG JW-Q18WUXA is equipped with the brand’s DUAL Inverter Compressor with Varied Speed Dual Rotary Motor, which has a wider rotational frequency. This should help save more energy along with delivering high-speed cooling. The 1.5-ton capacity is suitable for a medium-sized room. It has an energy rating of 3-stars, which, according to the brand, translates to the total annual energy consumption of around 1370.63 units. The fins are made of copper with the company's proprietary ‘Ocean Black Protection’ to provide higher durability for the air conditioner, especially in regions with high sand, salt, industrial smoke and pollutants, as per the brand. With the help of LG’s unique BLDC Motor and Dual Inverter Compressor, the AC operates at sound levels as low as 44dB, when put in sleep mode. This makes it a good appliance for your infant’s room.
