The Importance of Preventive Maintenance
Scheduled (preventive) maintenance reduces the risk of machine breakdowns by up to 70% and saves energy consumption.
Standard Checklist
- Indoor Unit: Clean the filter, evaporator coil, drain pan, blower motor, and check thermostat connections.
- Outdoor Unit: Clean the condenser coil (essential for heat removal), check compressor voltage and ampere current, and inspect bolt tightness and vibration.
- Refrigerant System: Check Freon pressure (suction & discharge) and inspect for oil leaks around pipe connection fittings.
Reporting
The maintenance vendor must provide a log‑book / service report detailing the condition before and after the service.
Field Notes from Pandan Teknik Technicians
The article above provides a general overview of what we frequently encounter in the field. However, each AC unit and room has unique characteristics (such as pipe installation length, ventilation, and heat load). If you notice similar symptoms on the AC in your home or business, it’s best not to jump to conclusions on your own. You can contact the Pandan Teknik team via WhatsApp to describe the issue in detail. We will help analyze whether a light service, spare part replacement, or a technical survey visit is needed so that repairs are targeted and cost‑effective.
