Where All That Water Comes From

Your air conditioner removes moisture from the air as it cools — on a humid Asheville summer day, a residential AC system can pull 5–20 gallons of water from the air every 24 hours. This water collects on the evaporator coil, drips into a drain pan below it, and flows out through a condensate drain line to the outdoors or a floor drain. When any part of this drainage path fails, water ends up where it shouldn't — on your floor, in your ceiling, or running down walls.

Clogged Condensate Drain Line: The #1 Cause

Algae, mold, and slime love the warm, wet environment inside condensate drain lines. Over time, this biological growth clogs the line and water backs up into the drain pan, eventually overflowing. You can sometimes clear a clog by locating the drain line exit outside your home and using a wet/dry vacuum to suction out the blockage. Pouring a cup of white vinegar into the drain access point monthly helps prevent clogs. If the line is severely blocked, a technician can use compressed gas or a special drain brush to clear it.

Other Causes of AC Water Leaks

A cracked or rusted drain pan allows water to drip through rather than flowing to the drain — common in systems over 12 years old. A disconnected drain line from vibration or poor installation can send water spilling out at the connection point. A frozen evaporator coil, once it thaws, can release water faster than the pan and drain can handle. And a dirty evaporator coil can disrupt water flow, causing it to drip off the coil in unintended directions.

Preventing Water Damage

AC water leaks can cause thousands of dollars in damage to floors, walls, ceilings, and belongings before you notice them. Installing a float switch on the drain pan automatically shuts off the system if water backs up — this $30 device prevents catastrophic damage. Annual AC maintenance includes condensate drain cleaning and pan inspection. If your AC is currently leaking water, call Quality Comfort for HVAC leak repair before the damage spreads.
