UPDATE (12 APR 2022) – We are operating our aircon services as usual during this Covid-19 period. Due to the high volume of customers, some delays may be expected. All technicians will adhere to strict guidelines. Please Whatsapp us for assistance. Thank you.


In the everyday sense

Most people would ignore their leaking aircon as they do not consider the issue an emergency. They tend to prolong the leaky situation it is too annoying to deal with and are forced to call an aircon servicing company to help fix it. Even though your aircon can still function while it is leaking water, prolonging the situation will cause your aircon to use up more energy, resulting in an increase in your electricity bills. The repair costs will also be higher as aircon leaks can cause irreversible damage if not treated as soon as possible.


During COVID-19 Pandemic

So while it may not exactly be an aircon emergency, it is still considered an aircon issue that requires immediate attention. During the Circuit Breaker period, only essential businesses were allowed to operate, limited only to emergency aircon repair services. Aircon servicing companies in Singapore were considered essential services but could only provide urgent aircon services. In this sense, aircon water leaking is considered an emergency repair, and aircon repair services can carry on.

Therefore, do not hesitate to contact an aircon servicing company to fix the issue.


What Can Cause An Aircon To Leak?









At times, it can be difficult to determine whether or not an aircon water leak should be considered an aircon emergency and requires urgent repair. This is because some leaks may be merely incidental while others can result from serious aircon issues. To assist you, we have provided a list of some common aircon leak causes and the steps on how to determine whether your aircon needs servicing. Also included are some dangers of aircon leaks.

  1. Dirty air filters









Most people neglect their air filters as they do not know the importance of clean aircon filters. Over time, the air filters will accumulate dust and dirt, causing the airflow to be blocked. The blocked airflow will then cause the evaporator coils to freeze. Once the frozen coil melts, the water will leak out of the aircon.

2. Blocked or disconnected drain lines

Just like air filters, drain lines can also get clogged due to a lack of proper aircon cleaning. The drain pipe will be clogged with accumulated dirt, causing the aircon water to backflow and leak at the back of the aircon unit.

3. Poor maintenance

Your aircon unit also requires regular aircon servicing to ensure that its components are clean and well-maintained. Poor maintenance will make your aircon prone to water leaks and other common aircon issues.

4. Improper installation

If your aircon is leaking even though the unit is newly installed, the likely cause would be improper aircon installation. You should check if your aircon was installed properly. It should have been installed on a slightly downward angle, not on a flat surface. In addition, if the aircon seals are not fitted properly, condensation may also occur which may lead to water leaks.

5. Air leak

Air leaks may occur due to condensation, which happens when warm air entering the aircon fails to pass through the vent. Air leaks can also be caused by loose seals. This problem should be solved by engaging a professional aircon servicing company.

6. Low refrigerant levels







Refrigerant coolants cool warm air entering the aircon and blow it out as cool air. However, if there is insufficient gas, the aircon will not blow cold air which causes the aircon to leak. In addition, you may experience bubbling noises or hissing sounds, which are signs of leaking aircon coolant.

In this case, an aircon gas top-up is needed. However, if you suspect a refrigerant leak, do engage an aircon servicing company quickly as it is harmful for both you and the environment.

At other times, however, air leaks can be due to some major issues such as the following:

  • Frozen evaporator coils
  • Cracked or overflowing drainage trays
  • A cracked or loose seal valve

If you suspect that your air leak is due to these major issues, you should engage with a professional aircon servicing company to resolve the issue quickly.


Is My Unit Leaking or Merely Experiencing Condensation?







Aircons normally experience condensation, especially when used in hot climates due to the way in which it turns warm air into cold air. However, excess condensation may be a sign that you are currently experiencing an aircon leak, which requires professional aircon servicing.

One clear indication that your home or office aircon might have a leak is if water always accumulates whenever you turn your unit on. To confirm this, check if there happens to be a pool of water underneath. If so, then it is possible that your evaporator coils have become frozen. Otherwise, if the leak appears to have a sweet chloroform scent, then your refrigerants may have actually become damaged. Either way, immediately engage with a professional aircon service company to examine the problem for you. You might still be able to have your aircon fixed; but if the damage is too severe, then a complete aircon replacement might be necessary.


Dangers of Aircon Leaks

  • They can damage the entire unit itself.

If you continue to use your aircon unit despite the presence of a leak, you might end up putting unwanted pressure on the compressor. This can cause it to overwork and eventually damage your entire unit. High electricity bills may result as well. As such, it’s best to wait for professional aircon servicing to repair it for you or replace it entirely if needed.

  • Harmful particles could be released.

Whether it be commercial or industrial aircons, refrigerants are an essential part of any unit since they serve to release warm air as cool air. That said, they can become extremely dangerous should they incur damage or begin to leak. This is because they contain chlorofluorocarbon (CFC) which can be extremely hazardous to your health if released into the atmosphere. When inhaled, this can cause several health problems such as:

  • Dizziness
  • Nausea
  • Cough
  • Eye, ear, and throat irritation
  • Headache
  • Dizziness
  • Chemical Burns

Overall, a refrigerant leak is considered a major aircon issue and thus requires urgent aircon repair. So make sure to immediately engage with a reputable air conditioning service should you experience such a problem.


Fixing an aircon leak yourself








If you want to attempt repairing your leaking aircon yourself, here is a guide for you.

Using the right aircon repair tools and having the knowledge to repair your aircon leak yourself can help you save time and money. As dirt buildup is a possible cause of aircon water leaks, you can clean your aircon regularly to prevent the issue from happening. Here are important things to take note of when cleaning an aircon yourself.

  • Disable your installed aircon and disconnect it from the power supply
  • Detach the aircon cover and inspect the vent where the air is sucked in. If the vent is clogged with dirt buildup, the cold air may be spreading to other areas, which caused the leak.
  • Inspect your aircon seals, especially around the vent and cooling sector to check for air leaks.
  • Check the condenser pump and pan for dirt buildup.
  • Use a wire brush to clean any dirt, dust and debris that have accumulated.
  • You may use a cleaning solution to fully remove any stubborn dirt which may be sticking to the vent, pan compressor and other parts.
  • Once you have finished cleaning your aircon, dry it properly to eliminate all moisture.
  • After reassembling your aircon, test it to ensure no more water leaks occur.


How To Avoid Aircon Leaking Water

After getting an aircon repair, it is important to maintain your aircon properly to avoid experiencing issues in the future. You should conduct regular inspections to check for dirt accumulation or damaged parts. If dirt has accumulated, clean the aircon filters and other components regularly so that your aircon will continue functioning in the long run.

You can also install a larger condenser pan so that water does not spill out.


Hiring A Professional Aircon Servicing Company







If the leak still persists even after your aircon repair, you should engage a professional aircon servicing company to inspect and fix the issue. Things to look out for when engaging an aircon servicing company is their expertise in performing various aircon servicing jobs, as well as fair and reasonable pricing. It is also wise to check their reviews and testimonials online to confirm the quality of their repair works.
