Air conditioners lose efficiency as they age. Older AC units consume more electricity and increase monthly electricity bills. This calculator helps estimate yearly electricity waste and potential savings with a modern inverter AC.
AC Efficiency decreases as system ages.
Energy Waste = Yearly Electricity Cost × Efficiency Loss
New 5 star inverter AC systems typically consume 25–35% less electricity compared to older units.
If your AC is older than 7–8 years and electricity bills are high, replacing it with an inverter AC can save significant energy.
New inverter AC systems can reduce electricity consumption by 20–35% compared to old models.
If repair cost exceeds 40% of the price of a new AC, replacement is usually recommended.
Old compressors lose efficiency and refrigerant systems degrade over time, increasing electricity consumption.
