Common Air Conditioner Problems

What's in the article?

With a hot and humid climate all year round, Singapore ranks as the country with the highest number of air conditioner users in Southeast Asia.

Given the heavy usage of air conditioners in Singaporean homes and offices, it’s no surprise why a lot of people encounter air conditioner problems on a daily basis.

While these problems usually require the help of an aircon service, there are still quick and easy fixes that you can do yourself to save time and money. 

Read our complete guide below to find out the most common AC problems and recommended troubleshooting tips.

1. Dripping or Leaking Water

The problem of an air conditioner dripping or leaking water is one of, if not, the most common aircon problem in Singapore. While this issue seems fairly easy to fix, it usually indicates a much bigger problem in your air conditioner unit.

If the aircon is leaking water inside, check the condensate drain line for any signs of clogging. However, if your aircon is leaking water from the outside, it could be due to a drain pipe blockage, a broken condensate pan or a lack of refrigerant gas.

2. Hot Air or Not Blowing Cold Air

An air conditioner that has stopped blowing cold air is a common cause of headache among aircon owners in Singapore. This usually happens when the unit stops producing cold air or has difficulty in keeping the room cool.

Since this is a very common aircon problem, there are also a lot of simple ways that you can do to troubleshoot the issue. First, check if the vents are open and functioning properly. Second, check the air filter for clogged debris or dirt build-up. Lastly, have the fan motor inspected by an aircon professional to diagnose if it needs immediate repair.

3. Producing Too Much Noise

Are you having trouble sleeping at night because of your squealing aircon? You’re not alone. 

Noisy aircon units continue to be one of the most common problems in different types of air conditioners. From high-pitched screaming to aggressive grunting noises, these sounds normally have their own possible causes — something that should tell you a lot about the kind of service and repair you will be needing.

4. Status Light Keeps on Blinking

Are you experiencing constant blinking in your aircon’s status light? Don’t worry, it’s not a secret code from another distant planet in space. This only happens when an AC wants to give you a heads-up that it’s currently experiencing performance-related issues.

There are a lot of reasons that can cause an AC’s status light to blink. It could be due to an electrical issue, a failure in one of the system’s parts or a warning that something needs immediate repair.

Whatever the case is, don’t panic. It’s just your aircon’s way of letting you know there’s something wrong.

5. Gas Leakage

An aircon gas leak is a serious problem that needs immediate repair and attention. When left unrepaired, this can pose serious health hazards for you and your family.

Since this is usually caused by corrosion or poorly connected valves in an aircon unit, professional assistance is strongly recommended.

However, a fast and simple way to check if your aircon is suffering from a gas leakage is to check for any smell of gas around the unit. If even the slightest hint of gas smell exists, call an aircon servicing company or technician right away to fix the issue.

6. Aircon Error Codes

Similar to an aircon’s status light, error codes are helpful in letting aircon owners know when there’s something wrong with the unit.

Error codes normally appear in numbers or symbols, each representing a unique warning or problem inside the unit. Depending on the brand, these numerical figures and icons can help you diagnose a problem for your immediate action.

7. Trunking Condensation

Trunking condensation happens when the casing used to cover your AC’s electrical  cables, PVC pipes and copper conduits begins dripping or leaking slight beads of water.

While condensation is usually normal in any air conditioner unit, experiencing the issue in the form of drippings or leakages is a sign there’s something wrong. Some of the potential reasons behind this problem include poor insulation, installation and blockages in the trunking system.

To fix the problem, your best bet is to contact a professional aircon servicing company or a technician to tighten or revamp your trunking system.
