In many Singapore homes, even the most well-maintained air conditioning units may eventually experience issues due to frequent usage. It is important for homeowners to recognise the signs that an aircon needs repair before it becomes a major expense. Let us dive into some common issues you may encounter with your air conditioner, and a guide for DIY (Do-It-Yourself) aircon troubleshooting in Singapore.
Common Aircon Problems and What They Might Mean
Aircon Leaks
Aircon leaks are one of the most frequently reported issues in Singapore homes. If you notice that your aircon is leaking, it may mean that there are drainage blockages due to algae or dust sludge.
Aircon Light Blinking
If your aircon light is blinking, your unit may be communicating a fault code. Common problems that may be signalled from blinking aircon lights include improper installation or system errors, depending on your model.
Poor Cooling
Have you noticed hot and cold spots in your room despite turning the aircon on? Poor cooling in an air conditioner may be caused by various issues such as clogged air filters, low refrigerant levels, and dirty condenser coils.
Musty Smell
A musty odour coming out from your aircon unit may be caused by the buildup of dust and other particles on the aircon filter. This may be common in units that have not been cleaned in a long time.
Unit Not Turning On
There are various reasons that an air conditioner cannot be turned on. This includes incorrect thermostat settings, a tripped breaker, dirty air filters, frozen coils, or other electrical issues that need professional attention.
Step-by-Step DIY Aircon Troubleshooting for Homeowners
Before deciding if you should get professional aircon troubleshooting in Singapore, here are some troubleshooting tips you can do at home.
Aircon Leaking
Water leaks from aircon units are preventable. You can try clearing the drainage pipe to allow the clogged water to flow out properly. However, there are other causes that require a different repair approach, such as dirt buildup in the coils or improper installation. Engaging a professional technician can help you identify and address the root cause.
Aircon Light Blinking
Modern air conditioning systems use specific sequences as a built-in troubleshooting tool. You can try to check your system manual to understand the patterns being shown. If you are unsure, contact a technician.
Poor Cooling
The most common cause of an aircon not cooling properly is wrong settings. Make sure your unit is set to cool mode and not just fan. If it is still not cooling, remove and clean your air filters. If it still does not work, you may need professional assistance.
Musty Smell
To get rid of musty odours from your aircon, check your air filters to see if they are clogged. Use warm, soapy water to clean it, ensuring it is completely dry before reinstalling it. You can also clear blockages from the drain line with a wet/dry vacuum. If the issue still persists, get in touch with a professional technician to inspect your unit.
Unit Not Turning On
Start by checking your power supply and ensuring that the breaker box has not tripped. Switch off at the isolator for 60 seconds, then try to restart it. If the problem persists, a professional inspection is needed on your unit before using it again.
When Should You Call an Aircon Service Company?
Determining when you should get a professional inspection over a simple DIY fix for your aircon can help you save costs. Sometimes, simpler issues with your air conditioning unit can be addressed by resetting the unit or cleaning dirty filters and drain pipes. However, a professional aircon repair and troubleshooting service in Singapore may be necessary if you experience persistent problems such as constantly weak cooling, electrical faults, compressor failure, or any issue with the outdoor unit. Aside from identifying the root problem, a professional technician is trained to handle situations that involve pressurised systems and high-voltage components. These components may pose harm if you attempt to inspect them on your own. Cool-Aire’s repair and troubleshooting service helps to give you an accurate assessment to ensure that your unit can perform optimally.
FAQ
How often should I clean my AC filters?
To keep your aircon performing optimally, clean the air filters every 1-3 months. If you use your unit more frequently, you may need more frequent cleaning.
Why is my aircon making a loud noise?
Unusual noises from your air conditioner may be caused by loose parts, a failing fan motor, or a refrigerant gas leak. Book a professional aircon troubleshooting in Singapore to address the issue promptly.
How to solve poor aircon air distribution at home?
Sometimes, despite a properly functioning unit, you may still feel insufficient air distribution in your home. Make sure that your vents are not blocked by large pieces of furniture such as sofas, cupboards, rugs, or drapes, as this can trap air and waste valuable energy. Check that there is no furniture within at least 25 cm from the vent to allow cool air to circulate.
