Air Conditioner Leaking Water Inside
in Omaha, Nebraska
Finding water pooling around your indoor AC unit or dripping from your ceiling is alarming — and it’s a problem that should be addressed quickly. Water damage from a leaking AC can ruin drywall, flooring, and insulation, and encourage mold growth if left unchecked. Midlands Heating & Air diagnoses and fixes AC water leaks throughout Omaha and the surrounding metro area.
Common Causes & What to Do
-
Clogged Condensate Drain Line
Clogged Condensate Drain Line
This is the most common cause of AC water leaks. As your air conditioner removes humidity from the air, it produces condensate water that drains through a PVC line to the outside or a floor drain. Over time, algae, mold, and debris can clog this line — causing water to back up and overflow the drain pan. A simple flush usually clears it, and we can install a float switch that automatically shuts the system off if the drain starts to back up again.
-
Cracked or Overflowing Drain Pan
Cracked or Overflowing Drain Pan
The drain pan sits beneath your indoor air handler to catch condensate. Over time, especially in older systems, the pan can develop cracks or rust through — causing water to leak even when the drain line is clear. Drain pans can be replaced without replacing the entire unit.
-
Frozen Evaporator Coil Thawing
Frozen Evaporator Coil Thawing
If your AC runs with a dirty filter, low refrigerant, or restricted airflow, ice can form on the evaporator coil. When the system shuts off, that ice melts — sometimes faster than the drain pan can handle — resulting in water overflow. If you’ve seen ice on your unit or refrigerant lines, this is likely the culprit.
-
Dirty Air Filter
Dirty Air Filter
A severely clogged air filter restricts airflow over the evaporator coil, causing the coil temperature to drop below freezing and ice to form. Check and replace your filter — it’s the first thing to address and often fixes the problem entirely.
-
Low Refrigerant
Low Refrigerant
Low refrigerant causes the evaporator coil to run too cold, leading to ice formation and eventual water leakage when it thaws. This also means your system isn’t cooling effectively. A technician needs to find and repair the leak, then recharge the system.
-
Improper Installation or Pitch
Improper Installation or Pitch
If your air handler isn’t perfectly level, or the condensate drain line doesn’t have the correct slope, water may not drain properly and can pool or overflow. This is common in systems that have been moved or in homes where equipment was installed by less experienced contractors.
