North India is again in that difficult summer phase when the AC runs longer, the meter spins faster, and families check electricity bills with real worry. On 13 May 2026, IMD warned of a 4–6°C rise in maximum temperatures over Northwest India during 12–18 May, while Rajasthan’s Barmer touched 48.3°C. Delhi is also expected to cross 40°C this week. Comfort is not optional, but careless cooling can become expensive. The fix is simple: do not stop using your AC; use it with better timing, sealing, airflow, and temperature control.
Why Your AC Bill Rises Faster During A Heatwave
During a heatwave, your AC fights hot walls, roof heat, warm windows, air leaks, kitchen heat, and repeated door openings. That extra load keeps the compressor running for longer cycles. BEE’s 24°C cooling campaign and India’s default 24°C AC setting guidance matter because every degree below the comfort level pushes the machine harder. So, the target is not “maximum cooling.” The target is stable cooling with less compressor time.
1. Set the AC at 24°C And Use The Fan
Set the AC at 24°C, then run the ceiling fan on low or medium. The fan moves cool air across your skin and makes the room feel more comfortable. Avoid setting 18°C after coming from outside. It does not cool the room instantly. It only forces the compressor to work longer.
2. Block Afternoon Heat Before It Enters
The cheapest cooling trick is stopping heat at the window. Close curtains between 11 am and 5 pm, especially on west-facing windows. Use blackout curtains, reflective film, bamboo blinds, or thick cotton drapes. In many Delhi-NCR and Rajasthan homes, afternoon sunlight heats the room more than outdoor air. Block that heat early.
3. Clean Filters Every Two Weeks
A dusty AC filter quietly raises your bill. When airflow drops, cooling slows, and the compressor works harder. During peak summer, clean split AC filters every 15 days. If you live near a main road or dusty lane, do it weekly. Keep the outdoor unit shaded, ventilated, and free from leaves.
4. Seal The Room, Not The Whole House
Cool only the room you are using. Shut bathroom doors, balcony doors, and unused room doors. Place a draft stopper or rolled towel near the door gap. If hot air keeps entering, your AC never gets a fair chance. This habit works well in rented flats where permanent insulation is difficult.
5. Use A Timer Instead Of Running AC All Night
Most bedrooms become cool enough after 90–120 minutes. Use sleep mode or a timer, then let the fan continue. On extremely hot nights, set the AC to restart after a gap rather than run nonstop. This protects comfort and reduces unnecessary power use.

FAQs
What AC Temperature Saves The Most Electricity?
Maintain at 24°C in a cooler environment, using a fan for comfort and to reduce compressor load.
Is it okay if I turn off the AC repeatedly?
No, switching frequently can consume energy. Use the timer, steady, or sleep mode.
Will Air conditioning Filter Cleaning Save money?
Yes, clean filters will help to improve air flow, lower compressor pressure, and facilitate quicker room cooling.
How is an Inverter AC better in hot weather?
Typically, yes, as it will vary the compressor speed, not restart at full load.
How to Reduce Your AC Utility Costs if You Rent Your Home?
Do not need to change much in curtains, door sealing, cleaning filters, using fans, and using timers.
