FAQs
What makes your duct-cleaning sanitizers eco-friendly?
Our sanitizers are plant-based solutions that use biodegradable surfactants and naturally derived antimicrobial agents such as thymol. They contain no chlorine bleach, ammonia, or volatile organic compounds (VOCs), so they break down harmlessly after application and do not release toxic fumes into your home or the Kingsport environment.
Will an eco-friendly sanitizer still eliminate mold, bacteria, and viruses in my HVAC ductwork?
Yes. The botanical ingredients we use are EPA-registered as disinfectants and have been laboratory-tested to kill 99.9 % of common pathogens, including black mold (Stachybotrys), E. coli, influenza, and coronavirus strains. They provide the same microbial kill claims as traditional chemicals but without harmful residues.
Is the service safe for children, pets, and allergy sufferers?
Absolutely. Because our products are food-grade and free from synthetic fragrances and dyes, they will not irritate sensitive respiratory systems or skin. We also use a controlled misting method that keeps airborne particles to a minimum. Most families can re-enter the treated space within 30 minutes once the ducts are dry.
How often should I have my air ducts cleaned and sanitized in Kingsport’s climate?
For most homes, we recommend a full cleaning and eco-friendly sanitizing every 3–5 years. However, if you have recent renovations, smokers, pets that shed heavily, or household members with asthma or allergies, an interval of 2–3 years is better. Kingsport’s seasonal humidity can encourage mold growth, so stick to the shorter end of the range if you notice musty odors or visible dust buildup.
What does the duct-cleaning and sanitizing process involve?
1) Our technicians inspect your HVAC system with a high-resolution camera. 2) We seal off registers and use a negative-pressure vacuum to pull debris toward our HEPA-filtered collection unit. 3) Agitation tools dislodge dust and dander from the duct walls. 4) After debris removal, we fog the eco-friendly sanitizer through the supply and return lines, ensuring full contact with interior surfaces. 5) We finish with a post-treatment camera check and provide before-and-after images so you can see the difference.
How much does eco-friendly duct cleaning and sanitizing cost, and does it save on energy bills?
In the Kingsport area, prices start around $399 for a typical single-zone home and vary based on square footage, number of vents, and system complexity. Because a clean HVAC system allows air to flow freely, customers often see energy savings of 5–15 % and experience fewer service calls for clogged coils or blower motors. It’s an investment that pays back through lower utility bills, longer equipment life, and healthier indoor air.
