FAQs
What is a rotating brush duct-cleaning system and how does it work?
Our rotating brush system uses powered, soft-bristle brushes attached to flexible rods that spin inside each supply and return duct. As the brush agitates dust, lint, and microbial growth stuck to the metal or flex-duct walls, a high-efficiency vacuum running simultaneously pulls the loosened debris into a sealed collection unit. Because the brush scrubs 360° around the duct interior, it removes build-up more thoroughly than air-whip or negative-air methods alone, restoring full airflow and improving indoor air quality.
Why is duct cleaning important for my Cosby home or business?
Cosby’s mix of humid summers, cool winters, and surrounding woodlands means your HVAC system constantly pulls in moisture, pollen, and fine Appalachian dust. Over time those contaminants accumulate in the ductwork, fostering mold, bacteria, and allergens that circulate every time the system runs. Professional cleaning eliminates this reservoir, helping reduce allergy symptoms, lowering system strain, and cutting energy costs by as much as 10-15 % because your blower motor no longer fights restricted airflow.
How often should I schedule rotating-brush duct cleaning?
National Air Duct Cleaners Association (NADCA) guidelines recommend a full cleaning every 3–5 years, but frequency can vary. In Cosby we suggest the shorter end of that range if you: • have pets that shed, smokers, or occupants with asthma/allergies; • run the HVAC year-round for heating and cooling; • have recently completed home renovations; or • notice visible dust around vents. Seasonal filter changes and an annual HVAC tune-up also help delay heavy build-up between cleanings.
Will the rotating brushes damage my ducts or insulation?
No. We select brush heads sized specifically for your duct diameter and material—metal, flex, or fiberboard. The nylon bristles are firm enough to dislodge contaminants but soft enough not to scratch coatings or tear flex-duct liners. Our technicians scope each run with a video camera first, avoid fragile sections, and adjust brush speed for delicate areas such as internally insulated ducts. We are fully insured and back every job with a workmanship guarantee.
How long does the service take and what should I expect on the day of cleaning?
A typical single-family home in Cosby takes 2–4 hours. Larger homes or businesses may take longer. You can expect: 1. Pre-inspection: We camera-scope the ducts and seal off each register. 2. Equipment setup: Vacuum hose is connected to the main trunk, creating negative pressure. 3. Rotating brush cleaning: Each vent line is brushed and vacuumed, starting furthest from the HVAC unit. 4. Sanitization (optional): EPA-registered antimicrobial fog can be applied. 5. Final inspection & airflow test. You don’t need to leave the property, and we protect floors and furnishings with drop cloths.
What are the warning signs that my air ducts need professional cleaning?
Contact us if you notice any of these indicators: • Persistent dust on furniture within a day or two of cleaning. • Musty or burnt smells when the HVAC starts. • Visible mold growth inside the return plenum or on vent covers. • Allergy or respiratory symptoms that improve when you leave the building. • Inconsistent room temperatures or weak airflow at registers. • Recent construction, fireplace use, or pest infestations. Addressing these issues promptly keeps your Cosby property comfortable, healthy, and energy-efficient.
