Our 6-Step Aircon Servicing Process

At StringsSG, we follow a proven 6-step approach to general aircon servicing in Singapore — ensuring your unit runs efficiently and reliably.

1. Air Filter & Front Panel/Cover Cleaning

Dirty air filters can block airflow and strain the aircon. Technicians clean or jet-wash filters to restore optimal airflow.

2. Cleaning of Evaporator Coil

The evaporator coil can collect dirt, reducing efficiency. The technician cleans it using a soft brush or vacuum.

3. Drain Pan or Tray Cleaning

Clogged drain pans may lead to leaks. Technicians clean out debris from the pan to ensure proper drainage.

4. Vacuuming of Drainage Pipe

To prevent water backup, the drainage pipe is vacuumed to remove blockages that may disrupt water flow.

5. Outdoor Condenser Check

Technicians assess the outdoor unit’s performance and recommend cleaning if necessary, based on inspection or customer request (extra charges may apply).

6. Monitor Refrigerant Gas Level

Technicians check the refrigerant gas level if poor cooling is observed or upon client request, and may recommend top-up if needed.
