AC Leaking Water Services

Diagnosis and repair for overflowing condensate pans, clogged drain lines, cracked drain pans, and water pooling around indoor air handlers.

Protecting your home from structural water damage caused by clogged or damaged AC condensate systems.

Diagnosis and repair for overflowing condensate pans, clogged drain lines, cracked drain pans, and water pooling around indoor air handlers.

Common Symptoms

• Water pooling around the base of the indoor furnace or air handler closet
• Water dripping through second-floor ceilings or light fixtures below the attic unit
• Secondary condensate drain line (outside pipe near eaves or window) actively dripping
• System shutting off unexpectedly due to an activated float safety switch
• Musty, damp odor or elevated humidity levels near the air handler closet

Possible Causes

• Primary PVC condensate drain line blocked by algae, fungal sludge, or dust buildup
• Cracked or rusted-through indoor drain pan (especially in units over 10 years old)
• Disconnected or unglued PVC drain pipe fittings inside attic or wall cavity
• Frozen evaporator coil melting faster than the drain pan can discharge water
• Faulty or clogged condensate removal pump in basement or crawlspace installations

Safe Homeowner Checks

• Immediately switch the AC system to "OFF" at the thermostat to stop condensate production
• Check the emergency drain pan beneath attic units; if standing water is present, clear the area
• Inspect the exit point of the drain pipe (typically outdoors near the foundation) for visible mud or debris
• Place towels or containers to capture active water and prevent ceiling collapse or drywall rot

Frequently Asked Questions

How much water does a typical central air conditioner produce?

In humid summer weather, a typical residential central AC system can extract 5 to 20 gallons of water from your indoor air every day. If the drain line becomes blocked, that moisture accumulates quickly inside your home.

Why did my AC shut off completely when water started backing up?

Modern installations include an electronic float safety switch installed in the drain line or emergency pan. When water rises, the float switch cuts the 24V control circuit to prevent water damage from destroying your ceilings or flooring.
