10 Reasons Why My Aircon is Leaking Water and How To Solve It
Have you ever heard a constant dripping sound from your aircon or felt warm air blowing out of the unit? These may be signs of your aircon leaking water. If left unaddressed, it could lead to costly repairs and plenty of other inconveniences. Here is a handy guide to solving your aircon leaking woes.
1. Blocked Drainage Pipe
An aircon unit blows cool air by generating condensation, and the excess liquid that forms is drained through a designated drainpipe. Prolonged use can cause dirt, grime, and debris to accumulate inside the pipe, slowing or blocking drainage, and eventually leading to a leak.
You should remove any blockages to the drainage pipe. DIY cleaning solutions, such as bleach or vinegar with warm water, or vacuuming the debris, can help achieve this. Persistent leaks will require a professional technician to clean the drainage pipe using specialised equipment and techniques.
2. Damaged Drain Pan
The drain pan collects condensed water from the evaporator coils as the unit cools warm air, before diverting this condensate to the drainage pipe. However, the drain pan can gradually crack or corrode over time, especially with older aircon units. The pan will not retain water as effectively, leading to overflow and an eventual leak.
Keep an eye out for any signs of damage and replace faulty components with new ones to prevent future leaks or other complications. You should regularly inspect the drain pan and address any noticeable issues before they worsen.
3. Faulty Drain Pumps
Aircon drain pumps push condensed water out of the aircon, but a malfunctioning pump can cause water to pool in the drain pan and eventually leak, even if the drainage pipe is clean and unclogged. This situation is common in older or poorly maintained aircon systems, where components wear down over time.
Inspect the drain pump and look for signs of damage or blockages. If a leak persists even while the pump is powered, prompt repairs or a pump replacement are needed. Replacing malfunctioning drain pumps can restore proper drainage and prevent further leakage that could discolour walls or promote mould growth.
4. Dirty Air Filters
Clogged air filters can also cause an aircon leak. Congested air filters impede airflow to the evaporator coils, potentially causing them to freeze. When the ice melts, water can overflow from the drain pan. Dirty air filters also force your aircon unit to work harder to cool the air, contributing to substantial wear and tear on components.
Regular aircon cleaning and air filter replacements ensure proper airflow, fully functioning evaporator coils, and reduces the risk of leaks. Consider washing the filters at least once a month, and replace them every 6 months if they become faulty.
5. Improper Aircon Installation
If a newly installed aircon suddenly starts leaking, it may be a sign of improper and uneven installation. When the aircon is set at an uneven angle, it can prevent water from properly flowing into the drainage pipe, causing it to pool and overflow from the drain pan, leading to leaks.
Poor installation work by inexperienced or rushing technicians can contribute to this issue. You can resolve this issue by seeking assistance from professional air conditioner technicians, such as Luxury Cool, to inspect and repair the unit as needed. With expert service, your aircon will be mounted securely and correctly, ensuring it functions without complications.
6. Low Refrigerant Levels
Aircon refrigerant generates cold air by moving hot air from the room to the aircon’s outdoor unit, releasing the heat through condensation while cooling down the air. A low refrigerant supply can cause the evaporator coils to freeze over, leading to a leak when the coagulated ice melts. Additionally, your aircon must work harder to cool the room, causing condensation to build up faster than it can drain.
If the aircon’s cooling efficiency seems low or if it makes unusual sounds, it may indicate low refrigerant levels. It requires immediate attention, as prompt action helps save on repair costs and protects you from potential health risks, such as breathing difficulties and nausea. Schedule regular aircon maintenance with a professional technician to keep refrigerant-related issues at bay and ensure your aircon remains functional.
7. Malfunctioning Aircon Compressor
An aircon compressor acts as a pump, regulating refrigerant flow to and from the condenser and evaporator coils to cool your home. Excess condensation may accumulate and eventually leak from the unit when a compressor malfunctions, resulting in clanking noises and warm air. This problem may be more pronounced with older aircons and extended use.
If you suspect your air conditioner’s compressor is faulty, call a professional technician to inspect it. Depending on its severity, a thorough repair or complete replacement of parts may help resolve leaks and prevent the aircon from failing.
8. Unclean Aircon Condenser
The aircon condenser is the white box outside your house. It is responsible for transporting indoor warm air out via tubes, condensing the initial warm vapour refrigerant into a liquid before dispensing it outdoors. Because of its location, dirt and grime can easily build up and potentially clog the condenser coils or pipes, leading to leaks.
While you can keep the condenser free of dirt and dust, water leaks can happen. In these circumstances, a qualified technician should handle the issue, as there may be underlying complications that require extensive repairs or replacement of parts.
9. Improper Airflow
Your aircon must be clean and in good condition to ensure air flows freely. Restricted airflow caused by dirty air filters or clogged drainage pipes, for example, could disrupt the cooling process, leading to frozen evaporator coils. Once the ice thaws, excess condensation has nowhere to flow, so it leaks out.
A handy tip to encourage adequate airflow in your aircon unit is to stick to a cleaning routine to clean various components and remove obstructions such as dust, grime, and fungus. If regular cleaning cannot stop the leak, you may need a professional technician to examine and repair the aircon.
10. Old and Loose Pipes
Over time, your aircon and its parts will wear down. This includes the pipes of your aircon unit, where the protective coating cracks or the pipes become loose at their joints. Both cases can cause leakage, which, if left unchecked, may lead to extensive damage, such as wall stains.
If the pipes’ protective covers are damaged, you can easily replace them with new ones. Be sure to check them regularly to catch potential issues early. If you notice any looseness in the pipes, have a skilled technician help you tighten them, as you may break them if you are unsure how to do it yourself.
