As a severe summer settles in, the India Meteorological Department (IMD) has issued a red heatwave alert for Delhi, Haryana, Punjab, Rajasthan, Uttar Pradesh, and parts of Madhya Pradesh. With peak temperatures in the Delhi National Capital Region (NCR) expected to hover between 43°C and 46°C, keeping your home cool becomes a priority. However, running your air conditioner continuously can cause your electricity bills to skyrocket. Operating your AC efficiently is crucial to surviving the heat without draining your wallet. Let’s look at the critical AC mistakes you must avoid during this heatwave and how you can save up to 24% on your power bill.
Understanding the Temperature and Energy Impact
Setting your thermostat too low is the most common mistake during a heatwave. Many believe that setting the AC to 18°C cools the room faster, but it only forces the compressor to run at maximum capacity for longer. Here is how different thermostat settings impact your power consumption, based on data from the Bureau of Energy Efficiency (BEE):
| Thermostat Setting | Energy Savings (Compared to 18°C) | Best Use Case |
|---|---|---|
| 18°C | Baseline (0% Savings) | Not recommended (maximum power draw) |
| 22°C | ~12% Savings | Ex
5. Forgetting to Clean the FiltersDuring a heatwave, dust and particulate levels spike. Dirty AC filters restrict airflow, forcing the indoor unit to consume more power while delivering less cooling. Clean your indoor unit’s filters every 10 to 14 days during peak summer to keep the system running efficiently. 6. Leaving the Outdoor Unit in Direct SunlightThe outdoor condenser unit is responsible for releasing the heat captured from inside your room. If it is blocked by dust or exposed to direct afternoon sun, its heat exchange efficiency drops. Ensure there is at least 30 to 45 cm of clear space around the unit, and consider installing a simple shade canopy to block direct sunlight without blocking airflow. Prepare Your Home for the Summer PeakTo maximize your cooling efficiency, pairing your AC with an energy-efficient BLDC ceiling fan is one of the smartest upgrades you can make. Here are some of the best-rated options available today: To track the heatwave status and see live weather warnings, check the official India Meteorological Department weather portal. Verdict: Small Habits, Big SavingsSurviving the Delhi heatwave requires smart management rather than running your AC at its lowest settings. By adopting the BEE-recommended setting of 24°C, cleaning your filters regularly, and keeping curtains closed during peak hours, you can stay cool while keeping your electricity bills under control. |
