FAQs
What is your eco-friendly sanitizing mist and how does it work inside my HVAC ducts?
Our sanitizing mist is a plant-based, EPA-registered disinfectant that is aerosolized into a fine, low-moisture fog. After we finish mechanical duct cleaning, we release the mist throughout the supply and return sides of your HVAC system. The microscopic droplets stay airborne long enough to contact all internal surfaces—metal duct walls, insulation, blower housing, and coil cabinet—where they neutralize 99.9 % of bacteria, viruses, mold spores, and odor-causing microbes. Because the active ingredients are derived from botanical oils, the product breaks down into harmless organic compounds rather than leaving chemical residues.
Is the mist safe for my family, pets, and the environment?
Yes. The solution contains no chlorine, ammonia, or synthetic fragrances. It has a Category IV toxicity rating—the lowest level recognized by the EPA—which means it requires no personal protective equipment once dispersed. Children, pets, and sensitive individuals can re-enter the treated area after a brief 30-minute ventilation period. The product is biodegradable, VOC-compliant, and manufactured in a carbon-neutral facility, aligning with Chattanooga’s growing commitment to sustainable living and clean water initiatives.
Why should I have my air ducts cleaned and sanitized in Chattanooga’s climate?
The Tennessee Valley’s warm, humid summers encourage mold and bacterial growth inside dark ductwork, while our pollen-heavy spring and fall seasons load the system with allergens. Regular duct cleaning removes built-up dust, dander, and debris; the subsequent sanitizing mist eliminates remaining microbes and neutralizes odors. Together, these steps improve indoor air quality, reduce allergy and asthma triggers, and help your HVAC system operate more efficiently during both cooling and heating seasons.
How often do experts recommend duct cleaning and sanitizing?
The National Air Duct Cleaners Association (NADCA) suggests a full cleaning every 3–5 years for most homes. However, in Chattanooga, we often recommend a 2–3 year cycle because of elevated humidity and pollen levels. Homes with pets, smokers, recent renovations, or family members with respiratory conditions may benefit from annual inspections and more frequent sanitizing treatments to maintain peak air quality.
What will the service visit look like and how long does it take?
1. Pre-inspection: We use video scopes to document the current condition of your ductwork. 2. Mechanical cleaning: Rotary brushes and HEPA-filtered vacuums dislodge and extract dust and debris. 3. Sanitizing mist application: We seal vents, introduce the mist, and let it dwell 15–20 minutes. 4. Post-inspection & report: We provide before-and-after images and an air-quality summary. A typical single-system home (≤2,000 sq ft) takes 3–4 hours start-to-finish. Larger homes or multiple systems may require most of the day. You do not need to leave the house; normal activities can resume shortly after the misting phase.
Will sanitizing my ducts help with energy efficiency and odor control?
Absolutely. Dust and microbial films on duct walls and HVAC components restrict airflow and insulate heat-transfer surfaces, forcing your system to run longer to reach set temperatures. After cleaning and sanitizing, homeowners often see 5–15 % reductions in utility bills and report more even room temperatures. The botanical mist also neutralizes lingering odors from pets, cooking, tobacco, or moisture, leaving a light, natural scent that dissipates within hours.
