FAQs
What is truck-mounted vacuum duct cleaning and how does it work?
Our technicians park a powerful vacuum truck at your Elizabethton home, connect a large 8–10" hose to your main duct trunk line, and place the entire HVAC system under negative pressure. While the truck vacuum pulls contaminants toward its 13,000–16,000 CFM collector, we move through each supply and return run with high-pressure air whips and agitation tools that dislodge dust, pollen, pet dander, mold spores and construction debris. Because the debris travels directly to the sealed truck hopper outside, none of it re-enters your living space, and the process is faster and more thorough than with portable equipment.
Why is air-duct cleaning important for homes in Elizabethton?
The Tri-Cities region experiences high pollen counts in spring, elevated humidity in summer and increased wood-smoke particles in winter. These pollutants settle inside your ductwork, where they circulate every time the HVAC system runs. Dirty ducts can aggravate allergies and asthma, create musty odors, restrict airflow and force your furnace or air conditioner to work harder. Professional duct cleaning removes the built-up contaminants, improving indoor air quality, supporting respiratory health and helping your HVAC equipment operate at peak efficiency.
How often should I have my ducts cleaned, and what signs indicate it’s time?
The National Air Duct Cleaners Association (NADCA) recommends a thorough cleaning every 3–5 years for most residences. However, you may need service sooner if you notice: • Visible dust plumes coming from supply vents • Dark streaks around vent covers • Unexplained allergy flare-ups or persistent musty smells • Recent remodeling, drywall sanding or new flooring installation • A rodent or insect infestation • You’ve moved into a previously owned home and don’t know its maintenance history. If any of these apply, call us for a free inspection.
What should I expect on the day of service?
Most single-system homes in Elizabethton take 2–4 hours to complete. When we arrive, we’ll do a walk-through, lay down protective floor coverings, and install corner guards to protect walls. We’ll cut a small access panel in the main trunk (later sealed to code) for the vacuum hose, then systematically clean each vent line. The truck engine runs outside, so you’ll hear a low hum but no loud compressors inside. After cleaning, we treat the system with an EPA-registered sanitizer on request, re-assemble everything, and leave your home exactly as we found it—only cleaner.
Can duct cleaning lower my energy bills and extend HVAC equipment life?
Yes. The U.S. Department of Energy reports that 25–40 % of the energy used for heating or cooling a home is wasted, often due to build-up that restricts airflow. Removing that debris lets air move freely, so your blower motor doesn’t work as hard and your system reaches set temperatures faster. Customers typically see 5–15 % reductions in utility costs and less wear on expensive components like blower motors, heat exchangers and coils, potentially adding years to the equipment’s service life.
Are you licensed and insured, and do you follow NADCA standards?
Absolutely. We are a Tennessee-licensed mechanical contractor, fully insured for both liability and workers’ compensation. Our team is NADCA-certified, meaning we follow the association’s ACR Standard for cleaning methodology, safety, and ethical conduct. You’ll receive before-and-after photos, a written completion report, and a satisfaction guarantee. If any vent isn’t cleaned to your expectations, we’ll return at no charge.
