FAQs
What does NADCA certification mean, and why should I insist on NADCA-certified technicians for duct cleaning in Graysville?
NADCA (National Air Duct Cleaners Association) certification is the industry’s gold standard for air-duct cleaning professionals. To earn it, our technicians must pass rigorous exams on HVAC hygiene, adhere to the ACR (Assessment, Cleaning & Restoration) Standard, maintain liability insurance, and commit to continuing education. Hiring NADCA-certified techs ensures that your ducts are cleaned with specialized equipment, proper containment, and documented procedures that protect your home, HVAC system, and indoor air quality. It also means you’re working with a company that is accountable to NADCA’s code of ethics and subject to random audits—peace of mind you won’t get from uncertified cleaners.
How often should Graysville homeowners schedule professional air-duct cleaning?
The EPA and NADCA both recommend having ducts inspected every 2 to 3 years and cleaned every 3 to 5 years, but local factors can shorten that window. Graysville’s humid summers, spring pollen, and occasional construction dust often prompt homeowners to clean closer to every 3 years. You should also consider more frequent service if you have pets that shed, household members with allergies or asthma, a recent renovation, or if you notice visible dust blowing from registers. Our free camera inspection helps determine whether cleaning is truly needed.
What signs indicate my HVAC ductwork needs cleaning?
Common red flags include: 1) Moldy or musty odors when the system runs. 2) Visible dust puffs or debris coming from vents. 3) Black streaks or dirt around supply registers. 4) Increased allergy or respiratory symptoms indoors. 5) Frequent filter clogging despite regular changes. 6) Rodent or insect droppings in or around vents. If you notice any of these, call us for a NADCA-certified inspection—often we can show you the interior of your ducts with a live video feed so you can see the problem yourself.
What is included in your professional duct-cleaning service, and how long does it take?
Our Graysville duct-cleaning package is a full-system service, not just a quick vacuum of the registers. It includes: (1) Pre-cleaning camera inspection and written estimate; (2) Sealing all supply and return grills; (3) Connecting a 5,000 CFM negative-air machine with HEPA filtration to create system-wide suction; (4) Agitating debris with rotary brushes, air whips, and skipper balls; (5) Cleaning blower compartment, evaporator coil, and drain pan where accessible; (6) Sanitizing ducts with EPA-registered antimicrobial (optional); (7) Post-cleaning camera verification and customer sign-off. Most single-zone residential systems take 3–5 hours, while larger homes with multiple HVAC units may require a full day.
Will duct cleaning really improve my indoor air quality and HVAC efficiency?
Yes—when performed to NADCA standards, duct cleaning removes built-up dust, dander, mold spores, and other pollutants that recirculate through your living space. Customers often report reduced allergy flare-ups, fewer musty odors, and less dust settling on furniture. Clean, unrestricted ductwork also allows air to flow more freely, which can lower blower motor strain and potentially cut energy use by 5-10 %. While results vary with system age and condition, combining duct cleaning with routine filter changes and seasonal HVAC maintenance offers the biggest boost to IAQ and efficiency.
How much does professional duct cleaning cost in Graysville, and do you offer guarantees or discounts?
Pricing depends on square footage, number of HVAC systems, and add-ons like antimicrobial treatment, but most Graysville homes fall between $399 and $649 per system. We provide flat-rate, up-front quotes—no bait-and-switch coupons. Every cleaning comes with a 12-month "Clean Duct" guarantee: if you find significant dust or debris in the ductwork we cleaned within a year, we’ll re-clean the affected section at no charge. Seniors, military, and first-responders receive a 10 % discount, and we regularly bundle duct cleaning with seasonal HVAC tune-ups for extra savings.
