Why Is Your Air Conditioner Leaking Water Inside?
Air conditioners naturally remove humidity from indoor air. The moisture normally drains safely outside through a condensate drain line. When something interrupts this process, water begins collecting inside your home.Common causes include:
- Clogged condensate drain line
- Dirty evaporator coil
- Frozen evaporator coil
- Restricted airflow
- Damaged or cracked drain pan
- Improper AC installation
- Low refrigerant levels
- Broken condensate pump
- Dirty air filter
- Improper unit leveling

Common Reasons an AC Leaks Water Inside Chapel Hill Homes
Clogged Condensate Drain Line
Dust, algae, and debris frequently block the drain pipe. As water backs up, it overflows into your home instead of draining outdoors.Frozen Evaporator Coil
Restricted airflow or refrigerant problems allow ice to form. When the ice melts, excess water overwhelms the drain system.Dirty Air Filter
A neglected filter reduces airflow, increasing the chance of coil freezing and indoor leaks.Cracked Drain Pan
Older systems often develop rusted or cracked drain pans that allow water to escape before reaching the drain.Condensate Pump Failure
Homes with basement or below-grade HVAC installations often depend on condensate pumps. When the pump fails, water accumulates rapidly.Professional diagnosis is recommended because several problems may occur simultaneously. Assistance is available at
