Air Cooler Electricity Consumption & Running Costs in India

Evaporative air coolers are the most cost-effective summer cooling solution in dry regions of India (Delhi, Rajasthan, UP, MP, Punjab, Gujarat). Unlike air conditioners that use power-heavy compressors, air coolers rely on a low-wattage water pump (15W–25W) and an axial fan or centrifugal blower (100W–200W).
