Due to the year-round heat and humidity in Singapore, homeowners may consider installing an air conditioning system. Therefore, it is advisable to keep all aircon units in their best condition by properly maintaining them. 

To do this, it is important to pay attention to issues that your unit has. One of the most common issues is aircon leaking water. It is a problem that needs to be addressed immediately to prevent further damage. However, it is often confused with aircon gas leak issues. 

How can we differentiate the two? What are their symptoms, and how can the cause be determined?


Indications That It May Not Be An Aircon Gas Leak

Aircon Dripping Water


Many homeowners believe that dripping water from the aircon is normal. This proves the importance of knowing why your aircon is leaking water. Water is pulled from the air. As the temperature drops and the dew point is reached, it then condenses on the outdoor unit coil. This is what causes the water to collect at the bottom of the unit. Additionally, insufficient level of refrigerant lowers pressure in the unit leading to ice build-up. When the ice melts, your unit’s drain overflows and the water begins to drip on the floor. 


Sudden Increase in Electricity Bill 

Your air conditioner may work harder than necessary if the cooling part of it isn’t functioning properly. This results in higher energy use, which ultimately raises the cost of your electric bill. 


Evaporator Accumulates Ice 


Ice build-up and freezing are things that can happen if regular aircon cleaning is not done. When the aircon is running, moisture naturally accumulates along the coil, so there is always some water to freeze if the coil gets too cold. More ice forms as a result of the coil’s inability to absorb heat due to the ice. This may be related to an evaporator leak that causes the coil to build up ice.


Aircon Is Not Blowing Cool Air

The refrigerant levels in your air conditioner may be low if your aircon is not cold or blowing warm air. This typically means that your system has a refrigerant leak. As a result, your air conditioner will keep running and pump heated air in an effort to reach the temperature you set on your thermostat. In order to prevent such issues from happening, it is recommended to schedule regular aircon maintenance.


What is Gas Leakage?


An aircon gas leak can be potentially dangerous if Freon, the refrigerant used in most air conditioners, leaks from the unit. This substance can be fatal if it builds up in a confined place. There are several ways to determine whether an air conditioner is leaking gas. 


Indications That Aircon Gas Is Leaking

Rusting on Aircon Unit

One of the common reasons why an air conditioner is leaking gas is due to corrosion. Particularly, the exposure of the coils to fluorides in water sources and chloride in detergents results in corrosion. These two result in coil deterioration that lets refrigerant leak. Therefore, it is crucial to be on the lookout for rusting that could indicate a gas leak.


Unusual Sound From the Aircon 

Typically, cracks or holes in the coils that circulate the refrigerant may be one of the reasons why your aircon has hissing noises. These hissing sounds could turn into a louder bubbling sound if the refrigerant in your system is leaking through a fairly wide hole. It is crucial to take any noises coming from your air conditioner seriously and have them inspected by a licensed aircon professional. 


Low Gas Pressure

Low gas levels will affect the cooling capacity of your air conditioner. The interior unit blower can start blowing warm air rather than cold, and the cooling efficiency will drop. Technicians can address this problem with an aircon gas top up service. 


Random Sweet Scent

Your air conditioner’s refrigerant absorbs heat and circulates cool air around the house. If the air conditioner smells sweet, there may be a refrigerant leak. The refrigerant in your system may crack over time and leak out – giving your air conditioner that distinctively sweet odour. 


Why Does An Aircon Gas Leak Need To Be Solved Immediately?

Health Risk

Tremors, skin cracking, convulsions, and other difficulties might result from short-term exposure to the gas. Therefore it must be handled carefully and disposed of safely by a qualified professional. Our team at DW Cleaning Group Singapore know how to handle your aircon’s gas leak so it is recommended to consult them immediately if this happens.


Deprived Comfort

Installing an aircon unit gives us the convenience to work in a cool environment. This gets taken away if an aircon gas leak occurs. Good thing there are professionals whom you can contact in these cases. 



Regular air conditioning maintenance will help your air conditioner avoid such problems and lengthen its lifespan, saving you from future pricey repairs. Additionally, you should look for the best aircon technicians to get your money’s worth back. One of the common mistakes homeowners make when opting for professional aircon servicing services is choosing unlicensed aircon servicing company. This may result in more harm than good to your aircon unit. 


Environmental Hazard

The refrigerant escapes from leaks and is released into the atmosphere, harming the environment. This is caused by each refrigerant’s individual chemical reactivity. Some refrigerants have extremely high reactivity. This implies that they can increase the greenhouse effect as they spread, ultimately resulting in higher global temperature. 

It is important to schedule regular maintenance in Singapore so that we can detect aircon gas leak incidents and prevent them from happening. Doing this can contribute to lessening the adverse effects of an aircon gas leak. 


Engage DW Cleaning Group Singapore for Aircon Cleaning Services

After identifying gas leak indications, it is not ideal to wait before calling in professionals. Exposure to dangerous compounds in the refrigerants is more likely if there is a delay. Engaging professionals as soon as possible can save your money and life. 

While waiting for them, it is recommended to do the following:

  • To prevent damage to the evaporator coil, turn off the air conditioner and wait for the ice accumulation to melt.
  • Dry up the air conditioner’s drips in the surrounding area.
