Many households in Pakistan still run their AC in winter — for cooling or just air circulation. The key question: what temperature keeps you comfortable without spiking your bill?
✅ The Right Temperature: 24-26°C
- Less strain on the compressor
- Lower power consumption
- Reduced risk of catching a cold/flu
- For just air circulation, use Fan mode or 26-27°C
⚠️ Important: Pakistan’s Slab System
If your monthly consumption crosses 200 units, your ENTIRE bill gets charged at the higher (unprotected) rate — not just the extra units.
This is the single most important point most people don’t know.

- Ecestar Ac 1.5 Ton
- Midea Ac 1.5 Ton
- Haier Ac 1.5 Ton
- Kenwood Ac 1.5 Ton
- Hisense Ac 1.5 Ton
| 24-26°C (Correct) | 18-20°C (Wrong) | |
|---|---|---|
| Consumption/hour | ~1-1.2 units | ~1.5-1.8 units |
| Monthly units | ~180-200 | ~270-330 (crosses 200!) |
| Billing slab | Lower/protected | Higher/unprotected |
| Estimated bill | Rs 6,500 – 8,000 | Rs 11,000 – 13,500 |
Bottom line: Just changing the temperature can roughly DOUBLE your bill — with no real added comfort.

Conclusion
If you’re running an AC in winter, keep it at 24-26°C — you get comfort, better health, and a lower billing slab. Running it at 18-20°C is simply wasting money.
