FAQs
What does it mean to have NADCA-certified technicians clean my air ducts?
NADCA stands for the National Air Duct Cleaners Association, the organization that sets the industry standard for HVAC hygiene. A NADCA-certified technician has passed rigorous exams on proper inspection, cleaning, and restoration of HVAC systems and must follow the ACR (Assessment, Cleaning & Restoration) Standard. Hiring certified techs assures you that the job will be performed with specialized equipment, documented procedures, and a strict code of ethics—giving you verifiable results, better system performance, and protection of your warranty.
How often should residential air ducts be cleaned in the Oak Ridge area?
Most homes benefit from a professional cleaning every 3–5 years, but Oak Ridge’s humid summers, pollen-rich springs, and occasional winter furnace use can shorten that interval. We recommend more frequent service (every 2–3 years) if you have pets that shed, family members with allergies or asthma, recent renovations, or if you notice visible dust buildup, musty odors, or inconsistent airflow.
What are the common signs that my HVAC ductwork needs cleaning?
Red flags include visible dust plumes or debris blowing from supply registers, stale or moldy odors when the system starts, a spike in allergy or respiratory symptoms indoors, rooms that are noticeably hotter or cooler than others, and unusually high energy bills. If you see dark streaks around vents or discover insect/rodent droppings in or near the ductwork, schedule an inspection right away.
What does your NADCA-compliant duct cleaning service include, and how long does it take?
Our standard service begins with a camera-assisted inspection to document duct condition. We then isolate each branch, attach a high-capacity HEPA vacuum to create negative pressure, and use rotary brushes and compressed-air whips to dislodge contaminants. Supply and return plenums, registers, grills, and the blower compartment are cleaned and sanitized. Finally, we provide before-and-after photos. A typical 2,000-sq-ft home with one HVAC system takes 3–4 hours; larger or multi-system homes may require most of the day.
Will duct cleaning really improve indoor air quality and HVAC efficiency?
Yes. Removing accumulated dust, pollen, mold spores, and pet dander reduces the number of airborne irritants that circulate through your living space. Cleaner ducts also allow for unrestricted airflow, which helps your furnace and air conditioner operate with less strain—often reducing energy consumption by 5–15% and extending equipment life. While duct cleaning isn’t a cure-all for every air-quality problem, it is an important component of a healthy HVAC maintenance plan.
Is the process messy, and do I need to leave my house while you work?
Professional equipment keeps the process clean and safe. Our HEPA-filtered vacuums maintain negative pressure so loosened debris travels directly from the ducts into sealed collection units, not into your rooms. We cover floors and furniture in the work area and wear protective booties. You can stay home during the service—just expect short periods of noise from the vacuum and air tools. When we’re finished, we remove all coverings, wipe down vent covers, and leave your home exactly as we found it—only cleaner.
