Ways to Reduce AC Costs

Set to 24°C - 26°C

Every degree below 24°C increases power usage by ~6-10%.

Use Fan + AC

Ceiling fans circulate cool air, allowing you to set the AC thermostat higher.

Clean Filters

Clogged filters force the AC to work harder, consuming up to 15% more power.

Average AC Power Consumption

Frequently Asked Questions

How much electricity does a 1.5 Ton AC use per hour?
A standard 1.5 Ton AC consumes approximately 1.4 to 1.6 units (kWh) per hour. However, an Inverter AC consumes variable power (often 30% less) depending on the room temperature, while a non-inverter AC runs at full capacity constantly.
Does an Inverter AC really save electricity?
Yes. An Inverter AC adjusts the compressor speed based on the heat load. If the room is cool, it slows down instead of turning off completely (like a non-inverter). This reduces power consumption by roughly 20% to 40% compared to standard ACs.
What is the ideal temperature to save electricity?
The Bureau of Energy Efficiency (BEE) recommends setting your AC to 24°C. Every degree cooler you set (e.g., 18°C or 20°C) increases your power consumption by about 6% to 10%.
How do I calculate AC Units manually?
Formula: (Wattage × Hours) ÷ 1000 = Units (kWh).
Example: If your AC is 1500 Watts and you run it for 8 hours:
(1500 × 8) ÷ 1000 = 12 Units per day.
