Every supply boot, the main trunk line and the air handler of a Germantown home had accumulated dust, debris and residue — the kind of build-up that keeps a house smelling musty no matter how much it is cleaned. Here is how Mold Pro Solutions remediated the whole system in a single day: trunk brushing and cleaning, furnace cleaning and sanitizing, every supply vent cleaned, then an EPA-registered antimicrobial fogged through the ductwork.


A homeowner in Germantown, MD booked a mold inspection with Mold Pro Solutions and the conversation quickly turned to the HVAC system. Air ducts are where a house's dust, moisture and spores collect, and a system that has never been opened can keep redistributing them every time the blower starts. Our guide to what causes mold in a house covers HVAC condensate and ductwork as one of the seven main sources.
When the registers came off, the picture was consistent from room to room: dust and debris settled in the supply boots, build-up along the main trunk, residue on the evaporator coil and the air handler interior, and dust-coated return grilles. The homeowner chose a whole-house HVAC and ventilation remediation rather than a room-by-room approach, and the work was scheduled for a single day so the system could be back online that evening.
The system was remediated as one job — furnace, trunk and every run — with an EPA-registered antimicrobial applied per its label, the same approach behind the HVAC work on our mold remediation projects, with before-and-after photos of each component.

Every Mold Pro Solutions remediation follows the industry standard — and includes a 2-Year Mold-Free Warranty.

Removing every register and return, brushing and vacuuming the main trunk and each supply run, cleaning and sanitizing the furnace cabinet, blower area and evaporator coil, and fogging the cleaned ductwork with an EPA-registered antimicrobial applied according to its label.
This Germantown system was completed in one day, from the first register to the final fogging, with the system restarted the same evening. Larger homes or multiple systems can take longer.
No. Fogging is the last step after mechanical brushing and vacuuming. Applied to dirty ducts it coats the dust instead of removing it, which is why it is never used as the primary cleaning method.
The evaporator coil and air handler are the wet side of the system, where moisture and dust meet. Leaving residue there would re-seed the freshly cleaned ductwork every time the blower runs.
Change filters on schedule, keep the condensate drain clear, control indoor humidity below 60 percent, and have the system inspected if a musty smell returns when the blower starts.
