Air conditioning systems require some form of refrigerant to create a cool and comfortable environment within homes or commercial buildings. This is especially so for our humid climate in Singapore. Because these systems need refrigerants to operate, it’s not uncommon for leaks to occur in your air conditioning system over time as wear and tear take its toll on moving parts and materials. But what are some common causes of aircon gas leakage, and what can you do about it? Coldway Aircon is an established aircon repair company, and this article explores the main causes of aircon gas leakage and how to address them.
What is an aircon gas leak?
Air conditioners use a type of refrigerant that contains chlorine, known as chlorofluorocarbons (CFC) which is used in the refrigerant cycle for the heat exchange process. Generally, CFCs are considered toxic chemicals and long-term exposure brings harmful effects on health.
When a gas leak occurs, you will notice that your aircon is no longer cooling your room as it should. This is because the refrigerant that is used for the heat exchange process is lost, making the heat exchange unable to occur.
Besides experiencing a faulty aircon system, you will notice a smell of chemical, sometimes resembling chloroform. This occurrence should sound some alarms for you to get it checked. Leaking air coolants will turn into gas that can cause nausea and difficulty in breathing. Repeated exposure to the gas can also lead to life-threatening medical conditions.

Causes of an aircon gas leak
#1 Clogged drain valve
Air conditioning gas leaks are often due to clogged drain valves. When the drain valve gets clogged, water and other material can build up, increasing pressure that eventually causes a gas leak. In addition, dirt and debris inside the drain valve can also result in a buildup in pressure and eventual leak.
To prevent this from happening, be sure to regularly flush out your drain valve by running water through it. If you notice any unusual sounds or smells emitting from your unit, there may be an issue with your drain valve. If so, contact a professional aircon technician immediately for assistance and servicing.
Aircon gas leaks can be attributed to many factors, but one of the most common is corrosion. When metal is exposed to oxygen, it begins to corrode and break down. This process is then accelerated by exposure to elements such as fluorides and chlorides. Over time, corrosion can cause tiny holes to form in metal surfaces, which results in leaks that allow refrigerant gas to escape.
#3 Low refrigerant charge
Another possible cause of aircon gas leakage is a low refrigerant charge. Low refrigerant levels can cause pressure drops in the air conditioning system, eventually leading to leaks or failure. If your unit has been running continuously, it’s possible that the aircon compressor is wearing out and may need replacement. It is also possible that there is a leak in the evaporator coil or seal that requires attention. If you’re unsure what the reason is, engage a reliable aircon repair company to diagnose the issue such that repairs can be made as soon as possible.
#4 Faulty ductwork connections or installation
If your aircon is leaking gas, this could be the result of faulty ductwork. This can happen due to poor installation or a loose connection. Regardless of what the cause is, this is something that needs to be addressed as soon as possible to prevent any further problems.
To fix it, contact a professional aircon servicing company and have them take a look at the situation. They should be able to tell you if there are any issues with your installation or connections and will make the necessary aircon repairs for you.
Aircon gas leakage can be a severe problem that can bring about health hazards and damage to your AC unit, or even fires or explosions. Therefore it is essential to take measures to prevent leaks from occurring. Be sure to have your aircon installed by a qualified technician and conduct aircon general servicing regularly.
