FAQs
What is precision duct sealing and why is it important for my Kingsport home?
Precision duct sealing is the process of locating and closing gaps, cracks, and loose connections in your home’s supply and return ductwork. In many Kingsport houses 20–30 % of the air your HVAC system conditions escapes before it ever reaches the registers, forcing equipment to run longer and harder. Sealing restores the designed airflow, improves comfort in every room, reduces energy waste, and keeps outdoor pollutants such as pollen and humidity from being drawn into the system.
How does your duct sealing service improve indoor air quality and ventilation?
Leaky ducts create pressure imbalances that pull attic, crawl-space, or garage air—often laden with dust, mold spores, and insulation fibers—into the living space. By sealing these leaks we stop that unfiltered air from entering the supply stream, helping your filters and air cleaners do their job more effectively. Balanced duct pressure also allows fresh-air ventilation systems and bathroom/kitchen exhaust fans to work as designed, giving your family cleaner, healthier air.
Will sealing my ductwork really lower my energy bills?
Yes. Because conditioned air is no longer lost, your HVAC equipment cycles less often, cutting heating and cooling costs by 10–30 % in most Kingsport homes. Sealing also allows the system to reach the set temperature faster, which can extend equipment life and may qualify you for local utility rebates or federal tax incentives tied to energy-efficiency upgrades.
How long does a typical duct sealing appointment take and will it disrupt my routine?
For an average 2,000 sq ft residence, the complete inspection, sealing, and post-test usually take 2–4 hours. Our technicians seal from inside the home, so there is no need to access every register or move heavy furniture. The sealant cures almost instantly, and you can run your heating or cooling system as soon as we’re finished. We schedule appointments at your convenience and leave the workspace clean.
What are the signs that my duct system needs sealing or repair?
Common indicators include hot or cold spots between rooms, excessive dust on furniture, musty odors when the blower starts, higher-than-normal utility bills, and HVAC equipment that seems to run nonstop. If you’re unsure, we offer blower-door and duct-leakage tests that measure actual air loss and pinpoint problem areas in line with Tennessee’s energy codes.
Is precision duct sealing safe for my HVAC system and does it come with a warranty?
Absolutely. We use UL-listed water-based mastic and Aeroseal® polymer particles that are non-toxic, low-VOC, and safe for metal and flex ducts alike. The process operates at low pressure and temperature, so it will not stress your blower, coils, or refrigerant lines. All workmanship is covered by a 10-year transferable warranty, and sealing will not void existing manufacturer warranties on your furnace, heat pump, or air conditioner.
