Causes of Aircon Water Leaks
Understanding the root of aircon water leaks is essential for effective resolution. From clogged components to refrigerant issues, these malfunctions can lead to unwanted dripping and potential damage in your home.
Blocked Drainage System
A blocked drainage system is a major culprit for water leaks in air conditioning units. Dirt, debris, and even mould can accumulate over time, preventing water from draining out effectively.
This blockage can create a backlog of water that spills out from the drain pan or finds other escape routes, leading to leaks.
Regular cleaning can prevent these blockages from forming. It’s essential to check the drainage system periodically and clear any obstructions immediately. If left unchecked, vibrations from your HVAC unit may worsen wear and tear, causing more significant damage and potentially costly repairs.
Simple maintenance steps can save money and hassle by ensuring your AC’s drainage system remains unobstructed and functional.
Dirty Air Filter
Your air conditioner works hard to keep you cool, but a dirty air filter can throw a spanner in the works. When the filter clogs with dust and debris, it restricts airflow over the evaporator coils.
This can lead to those coils dropping below freezing and ice forming. Once the AC is turned off or on a defrost cycle, that ice melts and may cause water leaks inside your home.
Keep your indoor air quality high and water leaks at bay by checking your AC’s air filter monthly. If it looks grimy or clogged up, replace it without delay. Regular maintenance ensures that mould growth doesn’t stand a chance in your system’s components.
Clean filters help maintain dehumidification processes efficiently so you stay comfortable all season long without unexpected drips from your unit.
Low Refrigerant Levels
Low refrigerant levels in your air conditioning system are a common culprit behind water leaks. This problem can make the evaporator coil inside the unit too cold, causing it to freeze over time.
As odd as it may sound, the ice built up on the coils must eventually melt, and excess water may overflow from the drain pan when it does. This overflow is often mistaken for a leak but is a sign of low coolant in your system.
To avoid this issue, check your air conditioner’s refrigerant regularly. An HVAC technician can safely handle refrigeration repair to refill any lost coolant. It’s crucial not to ignore these signs because prolonged low refrigerant levels not only cause leaks but could also damage other parts of your air conditioning or decrease its efficiency.
A well-maintained unit with proper refrigerant will avoid unnecessary freezing and save you from unexpected puddles around your air conditioner.
Damaged or Rusted Drain Pan
Over time, the drain pan in your air conditioning system might get damaged or rusted. This part of the aircon collects water that condenses from the cooling process. Small holes and cracks can appear if corroded, allowing water to leak out instead of draining away properly.
High humidity often speeds up this corrosion process, making rust a frequent problem for aircones in damp climates.
Vibrations from your HVAC unit are also culprits in damaging the pan. These constant shakes can cause wear and tear, sometimes even disconnecting the pan from its proper position. When this happens, you’ll notice water pooling where it shouldn’t – leading to potential water damage and mould growth in your home if not fixed swiftly.
If you spot any signs of corrosion or leakage around your drain pan, taking immediate action is essential to prevent further issues with your system.
