FAQs

What does it mean to have NADCA-certified technicians clean my air ducts?

NADCA (National Air Duct Cleaners Association) certification indicates that our technicians have completed rigorous training, follow the ACR Standard for HVAC hygiene, and use approved equipment and procedures. Hiring a NADCA-certified team in Cosby ensures your duct system is cleaned safely, thoroughly, and in compliance with industry best practices.

How often should residential air ducts be cleaned in Cosby’s climate?

In East Tennessee, we recommend professional duct cleaning every 3–5 years. Homes with pets, smokers, recent renovations, or allergy sufferers may need service more frequently—about every 2–3 years. A NADCA inspection can confirm the exact timing based on dust levels, moisture, and system condition.

What are the main benefits of HVAC duct cleaning?

Thorough duct cleaning removes accumulated dust, pet dander, mold spores, and other contaminants, which can: (1) improve indoor air quality, (2) reduce allergy and asthma triggers, (3) enhance HVAC efficiency by restoring proper airflow, and (4) prolong equipment life by reducing strain on blowers and coils. Many customers in Cosby also notice lower energy bills and less household dusting.

Will duct cleaning disrupt my daily routine?

Our NADCA-certified crew uses negative-pressure vacuum trucks and sealed, high-efficiency filtration, which keeps debris contained. A typical single-system home in Cosby takes 2–4 hours to complete, and you can stay in the house during the process. We protect floors, furniture, and vents, then perform a final walk-through to ensure cleanliness before departing.

Do you offer before-and-after visuals or reports?

Yes. As part of our NADCA Standard protocol, we document each job with digital photos or video. You’ll receive images of the supply and return trunks, main lines, and key branch ducts so you can see the difference. We also provide a written service report detailing the methods, equipment, sanitizers (if used), and any system issues we discovered.

Is duct cleaning covered by my HVAC maintenance agreement?

Routine maintenance plans usually include filter changes, coil cleaning, and system checks—not full duct cleaning. However, our Cosby customers on a maintenance agreement receive discounted pricing and priority scheduling for duct services. Ask our office to bundle duct cleaning with your next tune-up for additional savings.
