FAQs
Why should I have my air-duct system cleaned by a professional?
Over time, dust, pet dander, pollen and even construction debris accumulate inside supply and return ductwork. Each heating or cooling cycle can recirculate those contaminants up to 5–7 times per day, aggravating allergies, lowering HVAC efficiency and creating musty odors. A professional cleaning removes this buildup with specialized vacuums and agitation tools, restoring healthy airflow, reducing wear on your furnace or air conditioner and helping your indoor air stay as clean as possible.
How often do homes in Powell need duct cleaning?
Most national guidelines recommend a thorough cleaning every 3–5 years, but Powell’s mix of humid summers, leaf-heavy autumns and winter furnace use can shorten that interval—especially for households with pets, recent remodeling, or allergy sufferers. We typically suggest inspecting the system every two years and scheduling a cleaning when dust and debris exceed ¼" on duct walls or occupants notice increased allergy symptoms.
What signs indicate my ducts should be cleaned soon?
Common red flags include visible dust puffs from supply vents, dark streaks on vent covers, musty or burnt odors when the HVAC starts, uneven airflow, a noticeable increase in dusting frequency, or unexplained allergy or respiratory flare-ups. A spike in energy bills may also signal restricted airflow from heavy debris buildup.
What is included in your Powell duct-cleaning service?
Our NADCA-certified technicians start with a camera inspection to document buildup. We then seal each register, place the system under 2,000+ CFM negative pressure, and use high-velocity air whips and soft-bristle brushes to dislodge contaminants all the way to the plenum. The debris is captured by a HEPA-filtered vacuum. We finish by cleaning the blower compartment, evaporator coil housing, and return drop, then sanitize with an EPA-registered antimicrobial fog (optional). Before-and-after photos are provided so you can see the results.
Will duct cleaning really improve energy efficiency and indoor air quality?
Yes. According to the U.S. Department of Energy, 25–40 % of heating and cooling energy is wasted when systems are dirty. Removing obstructions lets conditioned air flow freely, so your furnace and AC cycle less often. Cleaner ducts also reduce the circulation of dust, mold spores and allergens, helping occupants breathe easier and lowering the burden on air filters and the HVAC coil.
How long does the service take and will it disrupt my household?
A typical single-zone home in Powell takes 2–4 hours; larger or multi-system homes may take a bit longer. We protect floors with drop cloths, wear boot covers and keep doors closed to maintain indoor temperatures. While the vacuum is running you’ll hear a low hum, but you can remain in the house and use electricity, water and Wi-Fi as usual. Once we’re done, you can run your heating or cooling system immediately.
