FAQs
Why is regular duct cleaning important for my HVAC system in Sewanee’s climate?
Sewanee sits on the Cumberland Plateau, where seasonal temperature swings, high humidity, and abundant tree pollen can quickly accumulate dust, mold spores, and allergens inside ductwork. When those contaminants build up, they restrict airflow, force your HVAC equipment to work harder, and circulate irritants throughout your home. Routine duct cleaning removes this buildup, protecting system components, reducing allergy triggers, and helping your heating and cooling run more efficiently year-round.
How often should I schedule professional duct cleaning for my home or business?
The National Air Duct Cleaners Association (NADCA) recommends cleaning every 3–5 years under normal conditions; however, Sewanee residents may benefit from a shorter cycle (2–4 years) because of elevated pollen counts and higher summer humidity. Consider cleaning sooner if you’ve recently completed a renovation, installed a new HVAC system, adopted shedding pets, or noticed visible dust around vents. Commercial buildings with higher occupancy—such as campus facilities—should be evaluated annually.
What signs indicate my air ducts need cleaning?
Common indicators include: (1) excessive dust on furniture shortly after cleaning, (2) musty or stale odors when the system starts, (3) visible dust or debris blowing from supply registers, (4) unexplained allergy or respiratory flare-ups, (5) inconsistent airflow between rooms, and (6) a recent spike in utility bills without a change in thermostat settings. If you experience any of these, schedule an inspection.
What is included in your duct cleaning service and how long does it take?
Our NADCA-certified technicians begin with a camera inspection to document duct conditions. We then isolate each branch, connect a high-powered negative-air vacuum, and use rotary brushes and compressed-air whips to dislodge contaminants. Registers, grilles, the blower compartment, and the evaporator coil are thoroughly cleaned, and we finish with an optional EPA-approved sanitizer. A typical single-family home (10–15 supply runs) takes 3–4 hours, while larger or older homes with multiple systems may take 5–6 hours. All work areas are protected and left spotless.
Will duct cleaning improve indoor air quality and energy efficiency?
Yes. Removing dust, pet dander, mold, and pollen particles lowers airborne contaminant levels, reducing allergy and asthma triggers. Clean ducts restore unobstructed airflow, allowing the blower motor and heat exchanger to operate under less strain. Studies show a properly cleaned system can improve overall HVAC efficiency by up to 20 %, translating into lower monthly energy bills and extended equipment life.
Is duct cleaning safe for older homes and historic properties common in Sewanee?
Absolutely. Many homes in Sewanee and on the University domain feature older plaster walls and fragile ductwork. Our technicians assess duct material (sheet metal, flex, or fiberboard) and select the gentlest agitation tools to prevent damage. We seal access points with code-approved plates and never use harsh chemicals that could harm historic finishes. You receive before-and-after video footage to verify a thorough yet preservation-minded cleaning.
