Frequently Asked Questions

How often should I service my aircon in Singapore? expand_more
For residential units in Singapore, we recommend servicing every 3 to 4 months to maintain efficiency and prevent mold buildup due to high humidity.
What is the difference between Hydro and Basic servicing? expand_more
Basic servicing involves surface cleaning of filters and covers. Hydro servicing uses high-pressure water jets to penetrate deep into the cooling coils, removing trapped dirt and bacteria that a basic wipe cannot reach.
Do you use genuine Daikin spare parts? expand_more
Yes, as Daikin specialists, we source original replacement parts to ensure compatibility, longevity, and to protect your manufacturer warranty.
Why is my aircon light blinking? expand_more
A blinking light is Daikin's diagnostic signal. It means the system has detected a fault (refer to our error code guide). We recommend switching off the power and booking a diagnostic inspection to prevent further damage.
Do I need to top up gas every time I service? expand_more
Absolutely not. Air conditioning systems are closed loops. If your gas is low, there is likely a leak. Blindly topping up gas is like filling a tire with a hole in it. Our gas logic is: Inspect pressure, find leak, repair, then fill.
What is "Aircon Jelly" and why is it dangerous? expand_more
Aircon jelly is a biological slime (bacteria and mold) that grows in the drain pan. It causes severe clogs, leading to water leaking and bad smells. Hydro servicing is the best way to eradicate it.
Is Nitrogen Testing necessary for leaks? expand_more
When a gas leak is deep inside the wall-mounted pipes, standard pressure gauges might not show it immediately. Nitrogen testing uses high pressure to definitively locate the exact point of the leak.
How long does a standard servicing take? expand_more
A standard 3-unit service usually takes between 45 to 90 minutes, depending on the current state of the units and the level of accessibility.
Will you clean up after the service? expand_more
Cleanliness is our hallmark. We use floor protection and waterproof covers during Hydro servicing to ensure your furniture and walls remain spotless.
Can I book a same-day appointment? expand_more
We prioritize urgent cases (total breakdown or severe leaking). While we usually fill slots within 24 hours, same-day availability depends on your location and the current technician schedule.
