Why Your Air Conditioner is Leaking and How to Fix It
It’s a scorching summer afternoon on the Sunshine Coast. You’re comfortably lounging in your air-conditioned home when you notice water pooling around your unit. Panic sets in, what’s going on? Don’t worry though because air conditioner leaks are common, and there are simple explanations and solutions. Plus we’re always here to help you understand what causes AC leaks and how to fix them.
Why is My Air Conditioner Leaking?
An air conditioner removes humidity from the air as part of its cooling process. This moisture turns into water, which is normally drained outside via a condensate line. If you notice water leaking indoors, it’s not part of standard operation. Various underlying issues could be causing this leakage, and addressing them promptly can prevent damage to your home and air conditioning unit.
Common Causes of Air Conditioner Leaks
1. Clogged Air Filters
Air filters help maintain airflow to the evaporator coils. If the filter gets clogged with dirt and dust, the airflow is reduced and the coils may freeze. When the system is turned off, the ice on the coils melts, creating excess water that could leak out if the drain pan overflows. Regularly cleaning or replacing your air filter can help prevent this.
2. Blocked Drain Line
Your air conditioning system includes a drain line to safely expel excess water. Over time, this line can get clogged with dust, debris or even mould, causing water to back up and eventually leak from the unit. It’s essential to have the drain line checked and cleared as part of your regular maintenance to avoid leaks.
3. Malfunctioning Condensate Pump
If your air conditioner is located in a basement or any area where water can’t easily drain, it relies on a condensate pump to remove the water. A malfunctioning pump won’t be able to drain water effectively, causing leaks. If you notice a leak near your pump, it may need repair or replacement to restore proper drainage.
4. Improper Installation
Air conditioners need to be installed at a specific angle to ensure proper drainage. If your unit was installed without the right incline, water may not drain out efficiently, resulting in leakage. Professional installation ensures that your system is positioned correctly, preventing future leaks and maximising efficiency.
5. Lack of Regular Maintenance
Like any home appliance, your air conditioner needs regular servicing to perform optimally. Without annual maintenance (at the very least), small issues can develop into bigger problems such as leaks. By having your system professionally serviced, you can identify potential issues like blocked filters, clogged drain lines, or failing components before they cause water damage.
