SERVICING & MAINTENANCE
Q: What does your normal aircon servicing include?
Our standard servicing includes cleaning of filters and covers, vacuuming of drainage pipes, checking gas pressure, and inspecting components for proper performance.
Q: How often should I service my aircon?
For residential use, servicing is recommended every 3–4 months. Heavier usage or commercial setups may require more frequent maintenance.
Q: What is a chemical overhaul and when is it necessary?
A chemical overhaul is a deep cleaning process where the fan coil unit is dismantled and thoroughly cleaned to remove hardened dirt, mold, and internal blockages. It is recommended for aircons that are not cooling effectively or have not been deep cleaned in over a year.

Common issues include dirty filters, low refrigerant, or thermostat setting errors. If the issue persists, a technician should be called to diagnose the problem professionally.
