Why Did My HVAC Leak and Damage My Ceiling?

Why is the AC Unit in my Attic Leaking Water?

Air conditioner leaks are messy, inconvenient and, unfortunately, not always discovered in time to prevent extensive damage. If your air handler is located in the attic, as is the case in many Texas homes, a leaky HVAC system can mean a damaged ceiling and pricey repairs. Here are three reasons why your HVAC unit might leak and damage your ceiling.

Reasons Why an AC Might Leak from the Ceiling

Air conditioning leaks are attributable to any of the following problems:

  • Clogged condensate line. The number one cause of an air conditioner leak is a clogged condensate line. When warm air blows over your AC’s evaporator coil, condensation forms. This condensation drips into a drain pan and is removed from your home through a condensate drain line. If this drain line becomes clogged with mold, sludge or dirt, the water backs up and overflows the pan. The water puddles in your attic and eventually leaks through the ceiling of your home.
  • Cracked drip pan. Related to a clogged condensate line is a cracked drip pan. As your AC unit ages, the pan can develop cracks or holes. If your AC unit was replaced, the drip pan might not be large enough for your new system.
  • Clogged air filter. When your air filter gets clogged with dirt, it blocks the airflow over the evaporator coil. This blockage causes the coil to get too cold and freeze. When the ice melts, it drips more water than the drip pan can handle. Overflows lead to wet insulation, faulty wiring and other potential problems in addition to ceiling damage.
