Question: which ac is low power consumption?
Answer: Says Abhishekh Jain, founder, Bijlibachao.com, “A 5-star rated window AC is as power efficient as a 4-star split AC. Also, look for an AC with a built-in inverter. Though more expensive, it consumes much less power.” An old 1.5 tonne AC uses around 1.5 units per hour, while an inverter AC uses only 0.91 units per hour.
