In Singapore’s hot and humid climate, regular aircon servicing is not just helpful. It is truly necessary for comfort, reliability, and energy savings. However, not every servicing job is the same. Some technicians rush. Others only clean the surface. As a result, many homeowners are unsure if their servicing is done properly. So, to help you feel confident, here is a simple and easy aircon servicing checklist to see if your technician is doing it right.
1. First — Filters Must Be Cleaned Properly
To begin, your technician should remove and clean the filters. In Singapore homes, dust builds up fast. Therefore, dirty filters block airflow and weaken cooling.
✔ Filters removed
✔ Washed thoroughly
✔ Dried and reinstalled correctly
If this step is skipped, the servicing is already incomplete.
2. Next — The Evaporator Coil Should Be Clean
After that, the evaporator coil must also be cleaned well. Over time, dirt, bacteria, and mold can build up inside your unit. Consequently, your aircon may cool slowly and smell bad.
✔ Coil cleaned
✔ Dirt removed
✔ No sticky residue left
When this part is done right, you should feel cooler air more quickly.
3. Then — The Drain Pipe and Drain Pan Must Be Cleared
Next, your technician should check the drainage system. In Singapore, clogged drain pipes are a very common issue. If ignored, leaks may happen.
✔ Drain pipe flushed
✔ Drain pan cleaned
✔ Water flow checked
This step prevents leaking water, stains, and mold.
4. After That — Cooling and Gas Levels Should Be Checked
Next, the cooling performance should be tested. A trusted aircon technician in Singapore will measure refrigerant correctly, not guess.
✔ Cooling tested
✔ Refrigerant checked
✔ No unnecessary gas upselling
This ensures honest and proper servicing.
5. Also — The Outdoor Condenser Needs Attention
Many companies ignore the outdoor unit. However, it plays a big role in cooling. When it is dirty, the aircon struggles.
✔ Outdoor unit cleaned
✔ Fan checked
✔ Condenser coil inspected
Therefore, complete servicing must include this part.
6. Moreover — Noise and Loose Parts Should Be Checked
Servicing is not just cleaning. A professional will also check screws and moving parts. As a result, vibration and noise reduce.
✔ Screws tightened
✔ No rattling sound
✔ Fan motion smooth
This keeps your unit safe and stable.
7. Finally — Testing and Clear Explanation
Lastly, your aircon should be tested after servicing. A good company will not rush this step. Instead, they explain clearly.
✔ Unit powered on
✔ Cooling verified
✔ Findings explained
This gives you peace of mind.
