- Roof or wall leaks seep into attic or crawlspace HVAC units, corroding drip pans and mounts.
These damages set the stage for mold growth and air quality decline, prompting professional extraction and component restoration.
What Role Does Condensation Play in HVAC Water Damage?
Condensation forms when warm, humid air contacts cold evaporator coils, creating 20–50 gallons of water daily that must drain properly. Improperly pitched drain pans or clogged condensate lines cause water to pool, rust drip pans, and seep into duct seams. Over time, trapped moisture accelerates metal corrosion and fosters fungal colonies inside coils and plenums, requiring thorough dehumidification and sanitization.
How Quickly Can Mold Develop After Water Exposure in HVAC?
Mold can establish visible colonies within 24–48 hours of moisture exposure in damp duct surfaces.
- Spores land on wet fiberglass, ductboard, or insulation and germinate rapidly.
- Stagnant water and high humidity create ideal conditions for spores to multiply.
- Visible black or green patches appear on coil fins, drip pans, and duct interiors.
Early intervention through professional HVAC cleaning halts mold spread and protects indoor air quality.
