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.
