❄️ Common Mistakes Homeowners Make With Aircon Usage

Aircon systems are designed to be reliable and efficient, but many common usage habits can unknowingly reduce performance, increase electricity bills, and shorten the lifespan of the unit.

In Singapore’s climate, small mistakes made daily can quickly add up to higher costs and more frequent breakdowns. Here are some of the most common aircon usage mistakes homeowners make, and how to avoid them.

1. Setting the Temperature Too Low

Many homeowners believe setting the aircon to 16°C or 18°C will cool the room faster. In reality, this only forces the system to work harder for longer periods.

Why this is a problem:

• Higher electricity consumption

• Increased strain on the compressor

• Higher risk of frozen coils

Better practice: Set your aircon between 24°C and 26°C for comfort and efficiency.

2. Not Cleaning Air Filters Regularly

Dirty filters restrict airflow, causing weak cooling and higher energy usage.

Common signs:

• Room takes longer to cool

• Airflow feels weak

• Dust visible on vents

Better practice: Clean filters every 2 to 3 weeks, especially if the aircon is used daily.

3. Ignoring Small Leaks or Dripping

Many homeowners ignore minor water dripping, assuming it is normal. In reality, leaks often worsen over time.

Possible causes:

• Clogged drain pipe

• Dirty evaporator coil

• Frozen coil

Better practice: Address leaks early to prevent mould growth and water damage.

4. Switching the Aircon On and Off Frequently

Turning the aircon on and off repeatedly does not save electricity. It actually causes higher power draw during each restart.

Why this happens: The compressor uses more energy when starting up.

Better practice: Maintain a steady temperature and adjust fan speed instead.

5. Skipping Regular Servicing

Many homeowners wait until the aircon is not cold before servicing. By then, dust, mould, and wear may already be affecting performance.

Better practice: Schedule servicing every 3 to 4 months for residential use.

6. Leaving Doors or Windows Open

Cool air escapes quickly when doors or windows are left open. Humidity enters the room, making the aircon work harder.

Better practice: Keep doors and windows closed when the aircon is running.

7. Using the Wrong Fan Mode or Direction

Incorrect airflow direction can cause uneven cooling and discomfort.

Better practice:

• Angle airflow slightly upward

• Use medium fan speed for even circulation

• Avoid blowing air directly at occupants for long periods
