Window Air-Conditioner

Window air conditioners are self-contained units designed to cool a single room or small space by fitting directly into a window. They house all major components—compressor, condenser, evaporator, and fan—within one compact unit. While considered a more traditional cooling option, they remain popular due to their durability, easy installation, lower repair costs, and space-saving design.

Although they lack the advanced features of inverter or smart AC systems, window units are still widely used in residential settings. Available in capacities from 0.5 to 2.5 tons, they offer energy ratings of up to 5 stars in India, where a higher star rating equates to better energy efficiency and cost savings.
