What Happens During an Aircon Servicing? Step-by-Step Guide

 If you’ve ever booked an aircon servicing appointment and wondered what exactly happens during the process, you’re not alone. Whether you’re a homeowner or business owner in Singapore, understanding what goes on during a routine service helps you see its value—and why skipping it can lead to bigger (and costlier) problems later on.

In this step-by-step guide, we’ll walk you through what typically happens during an aircon servicing in Singapore, and why you can trust Wei Wei Aircon for reliable and professional service.

Step 1: Initial System Check

Before anything else, the technician will inspect the unit’s overall condition and ask about any issues you’ve noticed (e.g., unusual noises, weak cooling, water leakage).It gives a quick idea of any underlying problems and determines if your system needs more than just basic servicing.

Step 2: Cleaning the Air Filters

The air filters trap dust, pollen, and airborne particles. Dirty filters reduce airflow and force your unit to work harder. Cleaning the filters with water and mild detergent helps to restore the optimal airflow.

Step 3: Cleaning the Fan Coil Unit

The indoor unit’s fan coil (evaporator) gets covered in dust over time, reducing its ability to cool efficiently. Technicians use a soft brush or chemical cleaner (depending on the condition) to remove dirt from the coil.

Step 4: Clearing the Drain Pipe

A clogged drainage pipe can cause your aircon to leak water, which can lead to ceiling stains and mold. Technician flushes the drain pipe with the high-pressure tools to prevent the water blockages and leaks

Step 5: Checking the Thermostat and Controls

The aircon might not cool properly if the thermostat is faulty or not calibrated. The remote and thermostat are checked if they are working properly and adjust the temperature settings if needed.

Step 6: Inspecting the Gas Pressure

Low gas levels (refrigerant) can affect cooling performance. The pressure gauges is used to check if your aircon has sufficient gas. If needed a gas top-up or leak test is also recommended.

Step 7: Testing the Entire System

Once all cleaning and checks are done, the unit is power on and tested it for cooling performance, airflow, and noise levels. This process ensures that the aircon is functioning smoothly and efficiently before leaving your premises
