Introduction

Using aircond and fan at the same time: cost-saving trick or higher electricity bills?

The answer might surprise you. Many Malaysians run both aircond and fan, especially at night. But does this combo really save electricity — or is it just a waste? This article explains the truth with real physics and usage strategies.

1. Why Do People Use Aircond & Fan Together?

This combo feels cooler and more comfortable.

  • Fans help circulate cool air from the aircond more evenly

  • Enhances comfort without lowering the aircond temperature

  • Ideal for large rooms or high ceilings

  • Promotes better sleep with moving air

TNB Study: Households using both fan and aircond reduced room temp by 1–2°C faster


2. How Fans Support Aircond Functionality

Fans don’t cool air, but they spread cold air more effectively.

  • Cold air sinks — fans help distribute it throughout the room

  • Prevents cold air from collecting in one spot

  • Reduces compressor workload Tip: Use ceiling or standing fans aimed opposite your aircond for balanced airflow.


3. Does Using a Fan with Aircond Save Electricity?

Yes — with the right strategy.

Main benefits:

  • You can raise the aircond temperature (e.g. from 22°C to 25°C)

  • Compressor works less = less energy use

  • Fans consume only 40W–75W vs aircond (up to 1,000W)

Savings example: Aircond at 25°C + fan = save 10–20% vs using 22°C without fan

4. When Using Both Becomes Wasteful

Wrong usage = no savings and higher bills.

  • Still setting low temp (18°C–22°C) despite fan use

  • Running both all night with no timer

  • Fan direction doesn’t help circulate air (e.g., blowing into walls)

  • Room not sealed properly — cool air escapes, fan circulates warm air


5. Efficient Tips for Using Aircond & Fan Together

  • Set temperature to 24°C–26°C with fan

  • Use auto-off timer for aircond after 3–4 hours — let fan continue

  • Keep doors/windows closed

  • Service your aircond every 3–6 monthsBonus: Use thick curtains or thermal insulation to retain coolness longer.


Conclusion

Using aircond and fan together isn't wasteful — if done right.

With proper control, the combo saves energy and keeps you comfortable. Just adjust temperature, use timers, and ensure the room is suitable for efficient cooling.

FAQs

1. Will using a fan while the aircond is on affect performance?

No — it actually improves cold air circulation.


2. Is ceiling or standing fan better?

Both are effective, as long as airflow direction is correct.


3. Can I use high-speed fan with aircond?

Yes, just don’t aim it directly at the aircond or disrupt airflow.


4. Is it okay to use both at night?

Yes — especially with timer or sleep mode.

5. When should I service my aircond to save energy?

Every 3–6 months to maintain performance and efficiency.
