When HVAC Leaks Lead to Hidden Water Damage

October 14, 2025

When a local realtor called about a water issue in a Madison, Alabama home, the team at ABC Cleaning & Restoration found the problem fast — and it was hiding right above the ceiling.


The A/C drain pan in the attic was full of water because the condensation line wasn’t draining properly. Even worse, the system didn’t have a kill switch to automatically shut it off when the pan overflowed. To make matters worse, the drain line wasn’t even routed outside — it was releasing water into the soffit, causing hidden damage to the home’s structure.


What We Found:

  • Condensation line clogged with algae buildup
  • No cleanout for maintenance access
  • Missing kill switch (so the system kept running)
  • Drain line improperly installed — draining into the attic instead of outside

These small installation errors can cause major water damage over time — including soaked insulation, wood rot, and mold growth.


What Needs to Be Done:

✅ Install a kill switch to shut the HVAC unit off automatically if the drain pan fills

✅ Add a cleanout for routine maintenance

✅ Re-route the condensation line to drain safely outside
