💧 If you’re seeing this around your A/C vents, cleaning the ceiling alone isn’t going to fix the problem.
We were called out to investigate heavy staining and microbial growth developing around multiple supply registers. Once we got into the attic and started digging deeper, we found the real issue — moisture and condensation developing around the supply boots and duct connections.
In South Louisiana, hot humid attic air meeting cold HVAC components can create some serious moisture problems when duct connections, boots and penetrations aren’t properly sealed and insulated.
Our team went through the system and:
✅ Removed and cleaned the supply grilles
✅ Cleaned and sealed the supply boots
✅ Sealed the duct connections
✅ Addressed air leakage around the ceiling penetrations
✅ Properly sealed and insulated the affected areas
✅ Cleaned and treated the evaporator coil
✅ Cleaned and serviced the drain system
We didn’t just clean what you could see. We addressed what was causing it.
If you’re noticing sweating vents, staining, discoloration or microbial growth around your A/C registers, don’t ignore it. Your HVAC system may be telling you there’s a moisture problem that needs attention.
