Stop Cooling Your Attic

    The Invisible Leak

    Ducts in Florida are typically located in the attic, where temperatures can reach 140°F. If you have tears, disconnected joints, or dried-out tape, two bad things happen:

    1. Cooling Loss: You pay to cool the attic while your bedroom stays hot.
    2. Infiltration: Your system sucks dirty, fiberglass-filled attic air into the return side and blows it into your living room.

    Mastic & Aerodynamic Sealing

    We don’t use “Duck Tape” (which falls off in a year). We use professional-grade sealants.

    Our Process:

    1. Inspection: We pressurize the system to find the leaks (often hidden at the junction boxes).
    2. Mastic Application: We paint a fiber-reinforced mastic paste over joints and seams. This hardens into a permanent, rubber-like seal that never dries out.
    3. Insulation Repair: Once sealed, we re-insulate the duct to prevent sweating.

    Make every degree of cooling count.

    What types of services do Duct Ninjas provide?

    We provide camera inspection, negative air vacuuming, deep roto-brush duct cleaning (our standard service), and EPA approved sanitizing to get rid of and prevent mold and mildew. 

    Most single-system homes take 2–4 hours; larger homes or multiple systems take longer. We’ll give you a precise window before we start.

    No. We seal registers, run HEPA filtration, and use drop cloths and shoe covers. Dust goes into our vacuum, not your living space.

    Yes—our sanitizer is EPA-registered for HVAC use. People and pets can re-enter once it’s applied and dried (typically 10–30 minutes), and there’s only a light, temporary scent.

    Please clear access to vents, returns, the air handler, and a driveway spot for our vacuum. Put pets in a safe room and make sure an adult is home.

    Every 2-3 years is recommended to prevent mold and musty smell. Or after every dusty renovation.
