What Affects AC Cost in a 1BHK Home?
6 key factors that directly determine your monthly AC bill
Number of ACs Running
High ImpactMost 1BHKs use 1 AC in the bedroom. Adding a second AC in the living room can double your monthly bill from ~₹2,000 to ~₹4,000.
AC Tonnage
Medium Impact1 ton AC costs ₹200–₹400 less per month than a 1.5 ton. Choose tonnage based on room size — oversized AC wastes electricity.
Electricity Rate (₹/unit)
High ImpactElectricity rates vary from ₹5–₹10/unit across Indian states. Maharashtra and Tamil Nadu charge more; UP and MP are cheaper.
Daily Usage Hours
High ImpactEvery extra hour/day adds ~₹200–₹300/month for a 1.5 ton AC. Running AC for 10 hrs vs 6 hrs = ₹800–₹1,000 extra per month.
Temperature Setting
Medium ImpactEvery 1°C lower setting increases power consumption by 6%. Running at 26°C instead of 22°C saves ~₹300–₹500/month in a 1BHK.
AC Star Rating
High ImpactA 5-star AC costs ₹400–₹700/month less than a 3-star AC. Over 5 years, that's ₹24,000–₹42,000 in electricity savings alone.
Your city electricity rate directly determines your monthly bill
Check the exact ₹/unit rate for your state — it can vary from ₹5 to ₹10+ per unit across India.
