95% of Malaysians Make This Aircon Mistake During Hot Weather (Avoid This to Save Energy & Money)

The most common aircon mistake in Malaysia is setting the temperature too low (16°C–18°C) and running it continuously without proper maintenance.
This causes higher electricity bills, poor cooling performance, and faster system breakdown.

Why Aircon Usage Matters in Malaysia’s Climate

Malaysia’s tropical climate puts heavy pressure on air conditioning systems due to:

  • High daily temperatures
  • High humidity levels
  • Dust and airborne particles

These factors increase the cooling load, forcing your aircon to work harder than in most countries. If used incorrectly, your system becomes inefficient and prone to failure.

Top Aircon Mistake Malaysians Make

Setting the Temperature Too Low (16°C–18°C)

Many people believe that lowering the temperature cools the room faster.
This is a myth.

Air conditioners cool at a fixed rate. Setting a lower temperature only forces the system to run longer—not faster.

What Happens When You Set Your Aircon Too Low

1. Continuous Compressor Strain

  • Compressor runs non-stop
  • No cooling cycles or rest period
  • Leads to overheating and wear

2. Higher Electricity Bills

  • Increased energy consumption
  • More heat needs to be removed
  • Costs spike during hot months

3. Poor Cooling Performance

  • Uneven temperature distribution
  • Some areas stay warm
  • Aircon feels “not cold enough”

4. Ice Formation on Coils

  • Restricted airflow from dirty filters
  • Coils freeze due to overworking
  • Leads to water leakage

5. Increased Risk of Breakdown

  • Compressor damage
  • Electrical issues
  • Expensive repairs or replacement

Best Aircon Temperature for Malaysia

Recommended Setting: 23°C – 25°C

This range:

  • Maintains comfortable indoor cooling
  • Reduces electricity consumption
  • Extends lifespan of your aircon

How to Use Your Aircon Efficiently 

1. Service Your Aircon Regularly

  • Clean filters every 1–2 months
  • Professional servicing every 3–6 months

2. Improve Airflow

  • Use fans to circulate air
  • Keep vents unblocked
  • Avoid placing furniture near airflow paths

3. Reduce Heat Entry

  • Close doors and windows
  • Use curtains or blinds
  • Avoid heat-generating appliances during peak hours

4. Use Smart Features

  • Timer mode
  • Energy-saving mode
  • Auto temperature control

Signs Your Aircon Needs Servicing

Watch out for:

  • Weak cooling during hot afternoons
  • Sudden increase in electricity bills
  • Water leaking from indoor unit
  • Weak airflow
  • Strange noises or shutdowns

Tip : If your aircon shows any of these signs, schedule servicing immediately to avoid major repairs.
