Nothing is more frustrating than an aircon that suddenly stops cooling, drips water, or makes strange noises—especially in Singapore’s hot and humid weather. Before calling for professional aircon servicing, there are simple checks you can do at home. This aircon troubleshooting guide will help homeowners spot common issues, fix minor problems, and know when it’s time to call the experts.
1. Aircon Not Cooling Properly
If your aircon blows warm air or takes too long to cool the room, check these:
Dirty air filters: Clogged filters block airflow. Remove and clean them every 2–3 weeks.
Low refrigerant gas: If cleaning doesn’t work, the gas level may be low. In this case, call for an aircon gas top-up Singapore service.
Wrong settings: Make sure the unit is set to “cool mode” and not just “fan.”
2. Aircon Leaking Water
Water leaks are common but often preventable. Causes include:
Clogged drainage pipe → Clear the pipe to allow water to flow out.
Dirty coils → Dirt buildup creates condensation. A chemical wash Singapore service can fix this.
Improper installation → If leaks happen often, call an aircon repair Singapore technician.
3. Aircon Making Strange Noises
Unusual sounds usually mean something is wrong.
Banging or rattling → Loose parts inside the unit.
Whistling or hissing → Possible gas leak.
Clicking → Electrical issue.
When you hear persistent noise, turn off the unit and call a technician.
4. Aircon Producing Bad Smells
Smelly aircon is often a sign of:
Mold and bacteria buildup in coils or filters.
Clogged drain tray that collects stagnant water.
Regular cleaning helps, but if the smell lingers, an aircon chemical overhaul Singapore service may be needed.
5. Aircon Switching On and Off
If your aircon turns on and off repeatedly:
Thermostat issue → Check if the thermostat is set correctly.
Overheating unit → Dirty coils or blocked airflow can cause the system to shut down.
Electrical fault → Call for a professional inspection.
When to Call a Professional
Some problems are easy to solve with DIY cleaning. But if your aircon still doesn’t perform well after these checks, it’s time to call a professional aircon servicing Singapore company. Regular maintenance not only solves issues but also prevents costly breakdowns.
