Frequently Asked Questions
How much does it cost to run AC per month in India?
A 1.5-ton 5-star inverter AC running 8 hours/day at the national average rate of ₹6.8/unit costs approximately ₹1,714/month. In Maharashtra (₹8.5/unit), the same AC costs ₹2,142/month. In Jammu & Kashmir (₹3.8/unit), it costs only ₹958/month. The state you live in is the biggest factor affecting your AC bill.
What is the annual AC electricity cost for an average Indian household?
The average Indian household with a 1.5-ton 5-star AC uses it for 5 months of the year (April–August), running 8–14 hours/day. Annual cost ranges from ₹7,500 in cooler states like Himachal Pradesh to ₹18,000+ in hot states like Maharashtra and Rajasthan. The national average is approximately ₹10,000–12,000/year.
How does heatwave affect AC electricity cost?
During heatwaves (45°C+), AC usage typically increases from 10 hours/day to 16–18 hours/day. Additionally, the compressor draws 20–40% more power at extreme temperatures. Combined, this increases your monthly AC bill by 80–120% during heatwave months. A 1.5T 5-star AC that normally costs ₹2,205/month in Delhi jumps to ₹3,969/month during peak heatwave conditions.
Which city has the highest AC electricity cost in India?
Mumbai has the highest per-unit electricity rate (₹8.5/unit), but Nagpur is arguably the most expensive city for AC overall because of both high rates AND extreme heat requiring 14–16 hours/day usage. A 1.5T 5-star AC in Nagpur costs approximately ₹4,305/month during peak summer — the highest in India.
How much can I save by switching from 3-star to 5-star AC?
For a 1.5-ton AC running 8 hours/day at ₹6.8/unit, switching from 3-star to 5-star saves ₹734/month or ₹8,808/year. In high-rate states like Maharashtra (₹8.5/unit), the saving is ₹918/month or ₹11,016/year. The ₹5,000–₹8,000 premium for 5-star typically pays back in 7–11 months.
Does running AC at 24°C vs 18°C really save money?
Yes — significantly. Each degree above 18°C saves approximately 6% on your electricity bill. At 24°C vs 18°C, you save 36%. For a 1.5T 5-star AC running 8 hrs/day, that's ₹617/month saved just by raising the thermostat from 18°C to 24°C. At 26°C, the saving is ₹822/month. Ceiling fans help maintain comfort at higher setpoints.
