FAQs
What is sealed ductwork and how does it differ from traditional duct systems?
Sealed ductwork refers to an HVAC air-distribution system in which every joint, seam, and connection is carefully sealed—typically with mastic, UL-181 tape, or aerosolized sealant—to eliminate air leaks. Traditional duct systems often rely on loosely fitted metal or flex-duct connections that can leak 20–30 % of conditioned air into unconditioned spaces such as attics, crawlspaces, or basements. By contrast, sealed ductwork keeps the air you pay to heat or cool inside the duct system until it reaches the living areas, improving comfort, efficiency, and indoor air quality.
Why is sealed ductwork especially beneficial for homes and businesses in Elizabethton, TN?
Elizabethton’s climate features both humid summers and chilly winters. Leaky ducts can draw hot, humid attic air into the system during summer and cold, musty crawlspace air during winter, making the HVAC equipment work harder to maintain set temperatures. Properly sealed ductwork prevents these seasonal air leaks, helping your system maintain consistent temperatures, reduce humidity swings, and lower energy bills—an advantage that is particularly noticeable in the variable Appalachian climate.
How does sealed ductwork improve indoor air quality (IAQ)?
Leaky ducts can act like vacuums, pulling dust, insulation fibers, mold spores, and other pollutants from attics and crawlspaces into the air stream and distributing them throughout the house. By sealing the duct system, the HVAC only circulates filtered, conditioned air, greatly reducing particulate matter and potential allergens. Many Elizabethton homeowners also pair sealed ducts with enhanced filtration or UV air-purification add-ons to further boost IAQ.
Can sealing my ducts lower my energy bills, and if so, by how much?
Yes. ENERGY STAR studies show that sealing and insulating ductwork can reduce HVAC energy use by 15–30 %, depending on the amount of leakage corrected and the efficiency of the existing equipment. In a typical Elizabethton household with mixed electric and gas utility costs, that can translate to $150–$400 in annual savings, paying back the sealing investment in as little as three years while continuing to save for the life of the system.
What is involved in the duct-sealing process and how long does it take?
A certified technician will first inspect and pressure-test your duct system to locate leakage points. They will then apply mastic sealant or UL-rated foil tape to accessible joints, boots, and plenum seams. For hard-to-reach runs, an aerosolized duct-sealing technology can be used from the inside. After sealing, the system is re-tested to verify leakage reduction. Most single-family homes in Elizabethton can be fully sealed in one day; larger homes or commercial properties may take two to three days.
Will sealed ductwork require special maintenance?
Sealed ducts do not require special ongoing maintenance beyond what you should already be doing: changing filters regularly, scheduling annual HVAC tune-ups, and ensuring registers remain unobstructed. In fact, because sealed ducts keep debris out of the system, they often stay cleaner, reducing the need for duct cleaning services. During yearly maintenance, technicians can visually inspect seals and reapply mastic if any mechanical work has disturbed the duct joints.
