FAQs
What does it mean that your technicians are NADCA-certified, and why is it important for Huntsville homeowners?
NADCA (National Air Duct Cleaners Association) certification verifies that our technicians have passed rigorous training and adhere to the industry’s highest standards for HVAC system inspection, cleaning, and restoration. In practical terms, it means we use approved methods, follow strict safety protocols, and document every step of the job. For Huntsville residents—where seasonal pollen, red-clay dust, and high humidity can all contaminate ductwork—choosing a NADCA-certified company ensures the job is done thoroughly, safely, and in compliance with national best practices.
How often should I have my air ducts cleaned in the Huntsville area?
The NADCA guideline is every 3–5 years, but in Huntsville we often recommend closer to the three-year mark because of the local climate. Our hot, humid summers promote mold growth, and springtime brings heavy tree and grass pollen that can accumulate in ducts. Homes with pets, recent renovations, or allergy sufferers may benefit from annual inspections and more frequent cleanings.
What are the common signs that my HVAC ductwork needs professional cleaning?
• Visible dust “puffs” or debris blowing from supply vents when the system starts. • Mold growth inside duct surfaces or on HVAC components. • Lingering musty or burning odors when the system runs. • Excessive dust settling on furniture shortly after cleaning. • Unexplained allergy, asthma, or respiratory flare-ups among occupants. • Higher energy bills caused by restricted airflow. If you notice any of these issues in your Huntsville home or business, it’s time for a NADCA-certified inspection.
What does your NADCA-compliant duct cleaning process include?
1. Pre-inspection: We open access panels, photograph conditions, and record system data. 2. System isolation: Supply and return sides are sealed to create true negative pressure. 3. HEPA-filtered vacuuming: A high-powered vacuum truck or portable unit draws contaminants out without releasing them indoors. 4. Mechanical agitation: We use rotary brushes, air whips, and skipper balls to dislodge stuck debris. 5. Component cleaning: Blower, coils, drain pans, grilles, and registers are cleaned and disinfected. 6. Optional antimicrobial fogging: An EPA-registered solution can be applied to inhibit future microbial growth—especially helpful in humid North Alabama. 7. Post-inspection & reporting: We provide before-and-after photos and a written summary so you have full transparency.
Will duct cleaning really improve my indoor air quality and energy efficiency?
Yes. Removing accumulated dust, pollen, pet dander, and mold spores reduces what your family breathes, leading to fewer allergy or asthma triggers. Clean ducts also restore full airflow, allowing your HVAC system to heat or cool more efficiently. Studies show that a clean system can cut energy consumption by up to 20%, particularly important during Huntsville’s hot summers when air-conditioning loads are highest.
How long does a typical duct cleaning take, and what should I expect on the day of service?
Most single-family homes in the Huntsville metro area take 2–4 hours, while larger homes or commercial spaces can run 6–8 hours. Our crew will: • Arrive on time, review the scope, and protect floors with drop cloths. • Shut off HVAC power, remove registers, and create access openings. • Run vacuum hoses from the truck or use contained portable units for high-rise buildings. • Show you debris collected and provide real-time photos. • Seal access panels and reinstall registers. • Clean up thoroughly before leaving. You can use the HVAC system immediately afterward.
