Non-inverter air-conditioners operate with a fixed cooling or heating capacity, relying on the periodic starting and stopping of their compressors to regulate indoor temperature. This process results in frequent power fluctuations, with high energy consumption during startup and shutdown phases. Unlike inverter air-conditioners that adjust compressor speed to match cooling or heating needs, non-inverter units do not offer this flexibility, leading to less efficient energy use and more noticeable temperature swings.

Non-inverter air-conditioners stops and starts repeatedly. The power consumption and current goes down when the operation stops, but it goes up sharply at the time of restart and thus it has high average power consumption and temperature variations. As a result, inverter airconditioners are more energy-saving and comfortable than non-inverter air-conditioners.

Let’s take an example of 1.5 Ton AC. Inverter AC can work from. 3 to 1.7 ton based on cooling requirement. Non-inverter AC can work at 1.5 ton only (fixed capacity)*.
