When the weather changes, our habits don’t always keep pace.
Delhi is entering that in-between season. The monsoon has pulled back, evenings are cooler, mornings are crisp, and the city feels less like a furnace. Yet if you walk through any apartment block in Dwarka or an office in Connaught Place, you’ll still hear the low hum of air conditioners running at the same intensity as peak summer.
This is where comfort becomes waste.
Because the weather has shifted, but our AC habits haven’t.
Why cooler evenings change the energy game

An air conditioner is designed for extreme scorching afternoons when ceiling fans just push around hot air. But in September and October, Delhi’s evenings dip to 22–24°C. That’s room-temperature comfort. Running your AC at full summer settings in these conditions is like wearing a woollen sweater in March. It’s unnecessary and wasteful.
The waste is not just about electricity. It’s also about:
- Over-drying the air: running ACs in cooler evenings can strip natural humidity, leaving your throat and skin irritated.
- Short cycling: compressors keep switching on and off, stressing the machine.
- Higher bills with lower benefit: you’re paying peak energy rates for marginal comfort.
The principle is simple: when outside conditions are already supportive, forcing your AC to work harder is like pushing against gravity.
The habits that no longer make sense
Let’s look at the specific habits Delhi households cling to and why they stop making sense once evenings cool down.
1. Keeping the thermostat locked at 20–21°C
In summer, dropping to 21°C feels like relief. On cooler evenings, it feels like stepping into a freezer. The AC keeps fighting an unnecessary battle, when setting it at 25–26°C would feel equally comfortable and save up to 20% energy.
2. Running ACs overnight
Many families still keep their ACs on from 10 pm till dawn. But with nights dipping, the temperature naturally regulates after 2–3 am. A fan, or the AC’s “sleep mode,” is enough. Continuous running just drives up units consumed.
3. Ignoring natural ventilation

Delhi evenings now carry a pleasant breeze. Opening a window for cross-ventilation in the early evening can cool a room faster than any compressor. Yet many still default to hitting the remote first.
4. Using the same cooling intensity across all rooms
Kids’ bedrooms, kitchens converted into workspaces, and drawing rooms don’t all need uniform cooling. But we rarely adjust. Energy is wasted where presence is minimal.
5. Forgetting the fan
A ceiling fan circulating cooler evening air reduces perceived temperature by 2–3 degrees. It means you can nudge the AC higher without losing comfort. Many ignore this basic principle.
Smarter alternatives for shoulder season comfort
Delhi households don’t need to abandon ACs altogether. They just need smarter use.
- Shift to fan + AC combos: run the AC for 30 minutes to bring the room down, then let the fan maintain airflow.
- Embrace sleep mode: Haier’s Gravity Series ACs, for example, use AI to learn your night pattern and adjust temperature gradually, ensuring comfort without overcooling.
- Experiment with dry mode: on humid days post-monsoon, dry mode consumes less power than full cooling and still keeps the room comfortable.
- Set realistic ranges: between 25–27°C is the sweet spot for both health and energy in this season.
- Trust auto mode: modern AI-enabled ACs regulate based on ambient conditions, far better than manual guesswork.
The hidden cost of ignoring the shift

Think of waste in layers:
- Financial: Every degree lower adds roughly 6% more power consumption. Over a month, that’s hundreds of rupees in wasted spend for a Delhi household.
- Environmental: ACs are energy-intensive appliances. Running them unnecessarily when the climate is already favourable compounds Delhi’s power load.
- Wear and tear: Compressors and filters aren’t designed to run at maximum load year-round. Overuse shortens appliance lifespan.
- Health: Sudden cold blasts against mild outdoor air can trigger colds, allergies, and sleep disruption.
In short: running your AC like it’s May in September is a tax on your wallet, your health, and the city’s grid.
The cultural angle: why we resist change
Here’s the hidden system at play.
We build habits in peak summer, switch on AC before bed, lock the setting, forget it. These habits calcify. Even when outside temperatures shift, our reflexes don’t. We treat AC use like muscle memory, not like an evolving practice that should adapt to seasons.
It’s the same reason people continue buying bottled water after installing a purifier. Or wear heavy perfumes long after summer ends. Habits outlast conditions. Unless we consciously re-evaluate.
Delhi homes that adapt differently
- The young couple in South Delhi: They set their Haier Gravity Series AC on “AI mode.” It auto-detects room occupancy and adjusts temperature, so they never waste cooling when they fall asleep with the TV on.
- The retired parents in Mayur Vihar: They’ve switched to ceiling fans for evenings, keeping ACs only for afternoons. Their bill dropped by 25% this month.
- The bachelor in Dwarka: He uses dry mode on his 1.6 Ton Gravity Series AC to manage humidity without chilling the room. He now studies comfortably without shivering under a blanket
Each story shows the same principle: technology plus awareness equals smarter comfort.
What smarter cooling really means
Smarter cooling is not about sacrificing comfort. It’s about syncing lifestyle with reality.
- Use AI features when available Haier’s Gravity Series offers self-learning climate control, so you don’t have to micro-manage.
- Use sleep mode instead of all-night cooling.
- Use dry mode to tackle dampness without wasting power.
- Use fans to amplify natural evening breezes.
Smarter cooling is knowing when your AC should step back and let the season do its work.
The bigger implication
Delhi is a test case for Indian cities. As climate patterns shift, we’ll face longer summers, unpredictable monsoons, and shorter winters. But in between these spikes are windows like this season when nature gives us relief. The question is whether we take it or override it with old habits.
Households that learn to adapt save money, reduce grid stress, and extend appliance life. They also model a new kind of urban intelligence comfort that’s conscious, not compulsive.
The final takeaway
If Delhi’s evenings are already cool, continuing peak-summer AC habits is not comfortable. It’s a waste.
This is the season to reset defaults. Nudge thermostats up. Try dry mode. Trust AI features in modern appliances like Haier’s Gravity Series ACs. And most of all, let your habits catch up with the season.
Because comfort isn’t about how hard your AC works. It’s about how well you adapt.
