Air conditioners have become more than a luxury in Singapore—they are a necessity for comfort, productivity, and health.
With the hot and humid climate, it’s no surprise that almost every household and office relies on cooling systems daily. Yet, many people still ask: what happens during aircon servicing?
This guide walks you through the entire aircon service process, step by step.
Whether you’re new to air conditioning maintenance or simply want to understand what you’re paying for, you’ll learn what to expect during servicing, why it’s essential, and how it improves both comfort and air quality.
Why Aircon Servicing is Essential in Singapore
With continuous usage, dust, dirt, and moisture accumulate inside the aircon.
Left unchecked, this buildup leads to reduced efficiency, unpleasant odours, higher energy consumption, and even health risks. That’s why regular aircon servicing is critical for homeowners and businesses.
The benefits include:
Improved air quality by removing dust, allergens, and mold.
Longer lifespan of your air conditioning system.
Better cooling performance in Singapore’s humid climate.
Lower electricity bills due to improved energy efficiency.
Reduced risk of costly repairs and sudden breakdowns.
Simply put, servicing work is a form of preventive maintenance—your aircon will perform better, last longer, and keep your family or employees comfortable.
Step-by-Step: What Happens During Aircon Servicing
When you schedule servicing, the technician will follow a structured process to check, clean, and maintain different aircon parts. Here’s a breakdown of what typically happens:
1. Initial Inspection
Aircon technicians begin by examining your unit to detect visible issues such as water leaks, weak airflow, or odd noises.
They’ll review thermostat settings and ensure the air conditioning unit switches on correctly.
The inspection phase helps identify early problems before they worsen.
2. Filter Removal & Cleaning
Cleaning of filters is one of the most important steps.
The air filter traps dust, pollen, and bacteria. If clogged, it reduces cooling performance and affects the air you breathe.
The aircon technician washes or vacuums the filters to restore airflow.
3. Coil & Blower Cleaning
Dust and grease often accumulate on condenser coils and the blower fan.
Cleaning the unit at this stage improves energy efficiency.
Sometimes, a chemical wash or a chemical wash solution is applied to deeply clean stubborn dirt.
4. Drainage System Flushing
Clogged drainage trays and pipes are common in humid Singapore.
The technician will clear the drainage system and disinfect the drainage tray to prevent the growth of mold, algae, and leaks.
Proper cleaning of the drainage ensures water flows out smoothly.
5. Refrigerant Levels Check
Cooling efficiency depends on correct gas pressure.
Refrigerant levels are inspected to ensure the compressor is working optimally.
If low, a gas top-up may be recommended.
6. Electrical Component Testing
Worn-out wiring or loose connections can be dangerous.
Technicians inspect the electrical components, including fuses, switches, and thermostats.
Servicing also involves tightening connections to avoid safety issues.
7. System Reassembly & Testing
Once aircon parts are cleaned and inspected, the system is reassembled.
The technician will switch it back on, check airflow, cooling strength, and listen for unusual sounds.
Adjustments are made to the electrical components and thermostat settings to ensure efficiency.
8. Final Performance Review
After servicing, your aircon unit is tested again to confirm everything is working smoothly.
Customers are informed of any underlying problems or recommended follow-up maintenance.
📌 In summary: During aircon servicing, every major part—filters, coils, drainage, refrigerant, and wiring—is carefully cleaned, checked, and adjusted.
