FAQs
What does it mean that your technicians are NADCA-certified?
NADCA stands for the National Air Duct Cleaners Association. A NADCA certification indicates that our technicians have completed extensive training, passed a proctored exam, and adhere to the ACR Standard—the industry’s gold-standard for HVAC system cleaning. In practical terms, you can expect knowledgeable pros who follow strict safety, cleanliness, and ethical guidelines every time they service your home or business in Erwin.
How often should I have my air ducts cleaned in the Erwin area?
The EPA recommends inspecting air ducts every 2-3 years and cleaning them on an as-needed basis. However, homes in Erwin that experience high pollen counts, heavy humidity, or frequent wood-burning stove use may benefit from a professional cleaning every 2 years. If you’ve recently completed renovations, noticed excessive dust, or had a mold or rodent issue, schedule a cleaning right away, regardless of the calendar.
What are the main benefits of professional duct cleaning?
1. Improved indoor air quality: Removing built-up dust, dander, mold spores, and pollen reduces airborne irritants. 2. Energy efficiency: A clean HVAC system can operate up to 20 % more efficiently, lowering utility bills. 3. Extended equipment life: Less debris means less strain on blowers and coils. 4. Odor removal: Smoke, pet, or cooking odors trapped in ductwork are neutralized. 5. Allergy & asthma relief: Cleaner ducts can lessen respiratory flare-ups, especially during Erwin’s peak allergy seasons.
What should I expect during the duct-cleaning appointment?
Our crew arrives in uniform with high-capacity HEPA-filtered vacuums, agitation tools, and video inspection cameras. After protecting your flooring and vents, we create temporary access points to connect the vacuum, place the system under negative pressure, and dislodge contaminants with rotating brushes and compressed-air whips. We finish by cleaning the blower, coils, and drain pan, resealing access holes, replacing filters, and providing photo documentation. A typical residential job in Erwin takes 3–5 hours.
Will duct cleaning damage my HVAC system or drywall?
No. NADCA protocols require non-invasive access methods that preserve system integrity. We use existing service panels when possible. If an additional 1- to 2-inch access hole is needed, it is cut in sheet-metal ductwork only—not drywall—and is sealed air-tight with a code-approved metal plate after service. Your HVAC warranty remains intact, and our work is fully insured.
How much does professional duct cleaning cost and what influences the price?
In Erwin, most single-family homes fall between $450 and $700. Pricing is based on square footage, the number of supply and return vents, system complexity (multiple HVAC units or zones), and any add-on services such as antimicrobial fogging or dryer-vent cleaning. We provide a free on-site estimate before work begins, and there are no surprise charges—only the agreed-upon, up-front price.
