As temperatures rise in June, air conditioners and HVAC systems start running around the clock. While they keep your home cool, they can also become a hidden source of water damage—especially when small leaks go unnoticed.

Many homeowners don’t realize that even a slow drip from an AC unit can lead to damaged drywall, warped windowsills, and mold growth over time.

How Air Conditioners Cause Water Damage

Air conditioning systems naturally produce condensation as they remove humidity from the air. Normally, this moisture is safely drained away—but when something goes wrong, water can start to build up.

Common causes of AC-related water damage include:

• Clogged condensate drain lines
• Dirty or blocked air filters
• Frozen evaporator coils
• Damaged or rusted drain pans
• Improper installation or poor drainage setup

When these issues occur, water can overflow or leak into surrounding areas.

The Most Common Problem Areas

AC and HVAC leaks often affect areas you might not check regularly:

• Around window units and windowsills
• Ceilings below attic or second-floor systems
• Walls near HVAC units
• Basements around central air systems
• Closets or utility spaces where units are located

Because these leaks are usually slow, damage can build up before you even notice it.

Why Small Leaks Cause Big Damage

It doesn’t take a major flood to create serious problems.
Over time, even a small, consistent leak can lead to:

• Warped or rotting windowsills
• Soft or crumbling drywall
• Peeling paint and bubbling surfaces
• Mold growth in hidden areas
• Damage to insulation and framing

The longer it goes untreated, the more extensive—and expensive—the repairs become.

Warning Signs of an AC Water Leak

Watch for these early signs during the summer months:

• Water pooling near your AC unit
• Damp spots on walls or ceilings
• Musty odors Increased indoor humidity
• Visible staining or discoloration

If you notice any of these, it’s important to act quickly.
