Discovering water pooling near your indoor air conditioning unit is understandably alarming, and addressing the cause promptly can help prevent water damage to your home. Old Glory Air Conditioning and Heating explains the most common reasons behind this issue.
As your air conditioner cools your home, it naturally produces condensation, which is designed to drain away through a condensate line. Over time, algae, dirt, or debris can clog this line, causing water to back up and overflow into your home instead of draining properly outside.
If your evaporator coil has iced over, often due to restricted airflow or low refrigerant, that ice will eventually melt, sometimes producing more water than the condensate drain system can handle, leading to overflow and leaking.
The drain pan positioned beneath your indoor unit is designed to catch condensation, but over time, especially in older systems, this pan can crack or corrode, allowing water to leak through rather than properly draining away.
If your indoor unit wasn't installed with the correct slight tilt needed for proper drainage, water may not flow toward the drain as intended, instead pooling and eventually leaking from unexpected areas.
Physical damage or disconnection somewhere along the condensate drain line can prevent water from reaching its intended exit point, causing it to leak out at the point of disconnection instead.
During periods of unusually high humidity, your system may produce more condensation than usual, and if the drainage system isn't functioning at full capacity, this can occasionally lead to overflow issues.
Beyond the immediate mess, water leaking from your AC unit can lead to damage to flooring, ceilings, or walls if the source of the leak is above a living space, and can also encourage mold growth if left unaddressed.
Checking whether the condensate drain line has an accessible clean-out point that can be cleared with a wet vacuum is one simple step homeowners can sometimes take, though persistent leaking generally warrants professional diagnosis.
If your air conditioner is leaking water indoors, our technicians can quickly identify the source and provide the appropriate repair to protect your home from further damage.
