FAQs
Why is professional air-duct cleaning important for my heating and air-conditioning system?
Over time, dust, pollen, pet dander, mold spores, and even construction debris collect on the inside surfaces of supply and return ducts. When the HVAC fan turns on, those contaminants are circulated through your home, where they can aggravate allergies, reduce system airflow, and force the equipment to work harder. A NADCA-standard cleaning removes this buildup, restoring proper airflow, helping the system run more efficiently, extending component life, and giving you cleaner, healthier air to breathe.
How often should ducts be cleaned in Sevierville’s climate?
Industry guidelines recommend a thorough cleaning every 3–5 years, but local conditions can shorten that interval. Sevierville experiences heavy spring pollen, humid summers that can promote mold growth, and occasional wild-fire smoke from the surrounding mountains. If you have pets, smokers in the home, recent renovations, or family members with asthma or allergies, we suggest inspecting your ductwork annually and scheduling cleaning about every 2–3 years or as needed based on buildup.
What signs tell me my ducts are due for cleaning?
Common indicators include: visible dust poofs from supply registers when the system starts; musty or stale odors when the HVAC fan is running; inconsistent airflow between rooms; an unexplained increase in energy bills; dark lines on carpet near vents (known as filtration soiling); and allergy or respiratory symptoms that improve when you leave the house. A quick look behind a vent cover with a flashlight—if you see heavy dust mats or matted debris—means it’s time for service.
What does your duct-cleaning process involve?
1) We start with a camera inspection to document the condition of the ductwork. 2) All vents and returns are sealed except the one we’re working on to maintain powerful negative pressure. 3) A HEPA-filtered vacuum truck or portable unit is connected to the main trunk line. 4) High-pressure air whips and rotary brushes dislodge built-up debris, which the vacuum immediately removes. 5) We clean and sanitize the blower, evaporator coil, drain pan, and register covers. 6) An EPA-approved sanitizer/mold inhibitor is fogged through the system on request. 7) Finally, we perform a post-cleaning camera inspection and provide before-and-after photos for your peace of mind.
Will duct cleaning disrupt my day or damage my home?
A typical single-zone home in Sevierville takes 2–4 hours to complete. Our technicians arrive on time, wear shoe covers, lay down protective drop cloths, and use corner guards so hoses never scuff walls. Because the vacuum creates a sealed negative-pressure environment, there is no dust release into the living space. You can remain in the home during the service, and in most cases the HVAC system can be turned back on immediately after we finish.
Does duct cleaning really save energy and improve indoor air quality?
Yes. According to the U.S. Department of Energy, 25–40 % of the energy used to heat or cool a home is wasted, often because contaminants restrict airflow and cause coils or blower wheels to become dirty. Removing that buildup allows the system to move air more freely, so it reaches set temperatures sooner and cycles off faster. Cleaner coils also transfer heat more efficiently. On the IAQ side, eliminating accumulated allergens and mold spores reduces airborne irritants, leading many customers to report less dust on furniture and fewer allergy flare-ups after service.
