How much does a 1.5 ton AC cost per month in India?

A 1.5 ton 3-star AC costs approximately ₹2,520–₹3,600 per month running 8 hours daily, depending on your state electricity rate. A 5-star inverter model costs ₹1,728–₹2,508 per month — saving ₹800–₹1,100 monthly.

How much electricity does a 1.5 ton AC use per month?

A 1.5 ton 5-star inverter AC uses approximately 252–300 units (kWh) per month when run for 8 hours daily. A 3-star model uses 360–400 units per month. At ₹7 per unit, this costs ₹1,764–₹2,800 monthly.

Does inverter AC really save electricity?

Yes. Inverter ACs save 30–50% electricity compared to non-inverter (fixed-speed) models. The variable-speed compressor adjusts output based on room temperature, avoiding the constant on/off cycling that wastes power in fixed-speed units.

What is the best temperature to set AC to save electricity in India?

The Bureau of Energy Efficiency (BEE) recommends 24°C as the default AC temperature. Each degree below 24°C increases electricity consumption by 6–8%. Setting 24°C instead of 18°C can save up to 36% on your monthly AC electricity bill.

Which state has the cheapest electricity rate for AC in India?

As of 2026, Goa, Himachal Pradesh and Uttarakhand have among the lowest residential electricity rates in India (₹3.80–₹5.00 per unit). Maharashtra and Andhra Pradesh have among the highest rates at ₹8.50–₹12.40 per unit for higher consumption slabs.

Is a 5-star AC worth the extra cost in India?

Yes, for most Indian households. A 5-star inverter AC saves ₹800–₹1,200 per month versus a 3-star model. At ₹10,000–₹15,000 higher upfront cost, the payback period is typically 12–18 months, after which you enjoy net savings for the remaining 8–10 year AC lifespan.

What tonnage AC do I need for my room?

For rooms up to 120 sq ft: 1 ton AC. For 120–180 sq ft: 1.5 ton AC. For 180–240 sq ft: 2 ton AC. Adjust upward if the room is on the top floor, faces west, has large windows, or has more than 2 occupants. Use our free AC Tonnage Calculator for a precise recommendation.
