Why is My AC Leaking Water?

If you’ve noticed water pooling around your air conditioner, you might be wondering why this is happening. Let’s explore some common reasons for an AC unit leaking water and what can be done about it.
Clogged Condensate Drain Line
One of the most frequent causes of water leakage is a clogged condensate drain line. Over time, dirt, debris, and algae can build up in the drain line, preventing the water from flowing out. When this happens, the water backs up and leaks out of the unit. Regular maintenance can help keep your drain line clear and prevent this issue.
Dirty Air Filters
Dirty air filters can also lead to water leakage. When the air filter is clogged, it restricts airflow over the evaporator coil, causing the coil to freeze. As the coil thaws, excess water is produced, which may overflow the drain pan and cause a leak. Changing your air filter regularly can help avoid this problem.
Low Refrigerant Levels
Low refrigerant levels can cause the evaporator coil to freeze. Similar to the effect of dirty air filters, when the coil eventually thaws, the excess water can lead to leakage. If you suspect low refrigerant levels, it’s important to have a professional check and refill it as needed.
Improper Installation
If your air conditioner was not installed correctly, it might not be level. An unlevel AC unit can cause the water in the condensate pan to spill over. Ensuring your unit is installed properly by a qualified technician is crucial for its efficient operation and to prevent water leakage.
Damaged Condensate Pan
Over time, the condensate pan can become damaged or rusted, leading to leaks. Inspecting the pan for any cracks or corrosion and replacing it if necessary can prevent water from leaking out.
Water leakage from your AC unit can be a sign of several issues, from simple maintenance problems to more serious concerns. Addressing these issues promptly can help prevent further damage and ensure your air conditioner operates efficiently.
