BEE Star Rating vs AC Consumption
Each star rating step reduces power consumption by 15–30%. The data below uses 1.5-ton AC running 8 hrs/day at ₹6.8/unit.

Key insight: Upgrading from a 3-star to a 5-star 1.5T AC saves approximately 108 units per month. At the national average tariff of ₹6.8/unit, that's ₹734/month or ₹8,808/year. The ₹5,000–₹8,000 price premium typically pays back in 7–11 months.

Tonnage vs Electricity Consumption
Oversizing your AC wastes electricity; undersizing causes the compressor to run continuously. Here's the consumption data by tonnage.

Heatwave Impact on AC Consumption
During extreme heat (45°C+), both usage hours and power draw increase significantly. Here's the data from India's hottest cities.
Heatwave data source: Based on AC usage data from May–June 2025 heatwave events across North India. During 45°C+ ambient temperatures, compressor power draw increases by 20–40% in addition to the 50–80% increase in daily usage hours. High-ambient rated (52°C) ACs perform better during extreme heat.

Frequently Asked Questions
How much electricity does a 1.5 ton AC consume per month in India?
A 1.5-ton 5-star inverter AC consumes approximately 252 units (kWh) per month at 8 hours/day usage. A 3-star model consumes 360 units/month — 43% more. At the national average rate of ₹6.8/unit, this translates to ₹1,714/month (5-star) vs ₹2,448/month (3-star).
Which state has the highest AC electricity consumption cost in India?
Maharashtra has the highest electricity rate at ₹8.5/unit, making it the most expensive state for AC usage. A 1.5T 5-star AC running 10 hrs/day in Mumbai costs ₹2,678/month. Nagpur (also Maharashtra) is even more expensive due to longer usage hours (14–15 hrs/day in peak summer).
What is the difference between 3-star and 5-star AC electricity consumption?
A 5-star inverter AC consumes approximately 30% less electricity than a 3-star non-inverter AC of the same tonnage. For a 1.5-ton AC running 8 hrs/day, the 5-star model uses 252 units/month vs 360 units/month for 3-star — saving 108 units/month or ₹734–₹918/month depending on your state tariff.
How does heatwave affect AC electricity consumption?
During heatwaves (45°C+ outdoor temperature), AC usage typically increases by 50–80% in hours per day. Additionally, the compressor works harder at high ambient temperatures, increasing power draw by 20–40%. Combined, a heatwave can increase your AC electricity bill by 80–120% compared to a normal summer month.
What is ISEER and how does it affect AC consumption?
ISEER (Indian Seasonal Energy Efficiency Ratio) is the BEE's efficiency metric for inverter ACs. A higher ISEER means lower electricity consumption. 5-star ACs have ISEER ≥ 5.0, while 3-star ACs have ISEER 3.3–3.6. An AC with ISEER 5.5 consumes 34% less electricity than one with ISEER 3.5 for the same cooling output.
How much does AC electricity cost during summer vs winter in India?
In most Indian cities, AC is used only during summer (April–September). A 1.5T 5-star AC running 10 hrs/day in summer costs ₹2,205/month in Delhi. In winter, AC usage drops to near zero. Annual AC electricity cost for a Delhi household is typically ₹12,000–₹18,000 for 5-star models and ₹18,000–₹26,000 for 3-star models.
