FAQs
What is a rotating brush system and how does it clean my HVAC ductwork?
A rotating brush system is a professional-grade tool that uses motor-driven nylon or polypropylene brushes attached to flexible rods. As the brush spins, it loosens dust, pollen, pet dander, and other debris stuck to the interior walls of your supply and return ducts. Simultaneously, a high-powered HEPA vacuum captures the dislodged contaminants, preventing them from circulating through your home. This dual-action approach is far more thorough than vacuuming alone, especially for older metal or fiberboard ducts common in Sewanee homes.
Why should I consider duct cleaning in Sewanee’s climate?
The Cumberland Plateau’s humid summers and cool, damp winters create ideal conditions for mold, mildew, and dust buildup inside ductwork. Over time, this buildup can reduce HVAC efficiency, raise energy bills, and aggravate allergies and asthma. A rotating brush cleaning removes these contaminants, improving indoor air quality, reducing musty odors, and helping your system run more efficiently—important when temperature swings are frequent in Sewanee.
How often do experts recommend duct cleaning with a rotating brush system?
Industry guidelines suggest every 3–5 years for an average household. However, Sewanee residents may benefit from more frequent cleanings—every 2–3 years—if they have pets, recent renovations, wood-burning fireplaces, or household members with respiratory issues. After any major construction or if you notice visible dust puffs from vents, schedule an inspection right away.
Is the rotating brush method safe for all types of ductwork?
Yes—when performed by certified technicians. We select brush heads sized for your duct diameter and material, whether it’s galvanized steel, aluminum flex, or fiberboard. The brushes are firm enough to remove debris but soft enough to avoid scratching or tearing the duct liner. Before starting, we block and protect delicate components (e.g., humidifiers, UV lights) and perform a post-cleaning inspection to ensure everything is intact.
How long does a typical duct cleaning service take and will it disrupt my day?
A whole-home rotating brush duct cleaning usually takes 2–4 hours, depending on the property’s size and duct complexity. Our team arrives with drop cloths and boot covers, isolates each zone, and maintains negative pressure so dust doesn’t escape into living areas. You can stay in the home during service; the HVAC system will be shut off temporarily but restored before we leave.
What does duct cleaning cost in the Sewanee area and what’s included?
For most single-family homes in Sewanee, rotating brush duct cleaning ranges from $450 to $650. Pricing covers: pre-inspection with video scope, sealing of vents and registers, mechanical brushing and HEPA vacuuming of all supply and return lines, cleaning of the main trunk and plenum, sanitizing fog (optional), and a final camera inspection with before-and-after footage. We provide a firm quote up front—no hidden fees—and offer discounts for annual HVAC maintenance plan members.
