Most Popular Aircon Problems & How to Deal with Them

Aircons are complex machines that serve a simple purpose—to provide cool environments in homes and corporate spaces. In hot and humid countries like Singapore, this is a little more than a necessity. However, like all machines, your aircon can also experience problems from time to time. There are a few issues that seem to occur more frequently, and knowing how to deal with these common aircon problems can help you nip them in the bud, or at the very least, get timely professional help before they escalate. Here’s how you can use aircon troubleshooting in Singapore to help you do just that.

Poor Cooling

Poor cooling typically stems from two main components in your aircon unit—the air filters and the compressor. The former can become clogged by dust and debris over time if you’re not cleaning it regularly, resulting in restricted airflow and reduced cooling efficiency. The latter, however, is more complex, and if your aircon’s poor cooling is caused by problems in the compressor, it would take more than just superficial cleaning. As mentioned, it’s important to perform regular filter maintenance by cleaning or replacing air filters every one to three months depending on frequency of usage. If getting your filters cleaned isn’t doing anything to remedy the problem, and your aircon is not cold, then you may want to consider getting aircon troubleshooting in Singapore as it’ll most likely be a compressor issue that needs a trained technician to look at.

Strange Noises

We often fear our machines making weird noises as it probably means that something’s up in their systems. Aircons are no exception, and common sounds you can hear from them include rattling and squealing. The former is usually a result of loose parts of debris within the unit, while the latter may indicate worn-out or slipping belts. 

Should you encounter similar strange noises in your aircon unit, we recommend inspecting the unit for loose screws, bolts, or debris; sometimes, the solution is as easy as tightening loose components. However, if your aircon is approaching the end of its shelf life with worn-out belts and other essential components, then it might be time to get an aircon replacement in Singapore instead.

Frozen Coils

Dirty evaporator coils or restricted airflow are both possible reasons behind frozen coils. As dust and dirt accumulates on the evaporator coils, heat exchange is impeded, which leads to freezing. Clogged filters or blocked ducts are also possible factors.

Once again, performing regular aircon maintenance by cleaning or replacing air filters can go a long way in preventing this from happening. You should also check for obstructions in the ducts or vents that may be further limiting airflow.

Inadequate Airflow

So far, clogs and dust buildup seem to be the main culprit behind common aircon issues, and inadequate airflow is no different. However, in this case, there are also other factors like issues with the fan motor, dust, debris, or even pest infestations.

Regularly inspecting and cleaning your duct can help maintain unobstructed airflow, but if you suspect that the issue lies with the fan motor, it might be better to get professional aircon troubleshooting in Singapore instead.

When to Seek Professional Help

When it comes to aircon issues, there are some that are easy and safe enough to fix on your own, and there are some way above your paygrade. It is therefore important to know when to seek professional help. Here are some situations where it’s advisable to contact an expert:

Refrigerant Leaks: If you suspect a refrigerant leak, it’s best to avoid attempting to fix it yourself as refrigerants are hazardous and handling them requires specialised knowledge and equipment. While you may worry about the aircon gas leak repair cost, rest assured that GoodCool provides affordable but reliable services, such as aircon gas top up and more.

Electrical Issues: It goes without saying that any problems with the electrical components of your aircon unit should be addressed by trained professionals to prevent electrical hazards. 

Unusual Smells: If you notice unusual odours coming from your aircon, it may indicate mould or mildew growth within the system, which requires thorough professional cleaning by technicians with the appropriate tools and solutions to do so.

Persistent Problems: If you’ve tried troubleshooting common issues without success, or if the problem recurs shortly after DIY repairs, then it’s probably time to let an expert take care of the issue. Chances are, they may spot an issue that isn’t easily detected by untrained eyes.

Regular Maintenance Prevents Problems

Ultimately, making the effort to regularly maintain your aircon unit remains the best preventive measure against aircon issues. However, without professional maintenance, you may miss out on certain things that could eventually cause problems. The same can also be said for DIY aircon repairs.
