FAQs
Why is duct cleaning important for my HVAC system in Charleston’s humid, coastal climate?
Charleston’s warm, humid air encourages mold, mildew, and dust accumulation inside ductwork. Salt-laden coastal breezes can also corrode metal components. Professional duct cleaning removes biological growth, salt residue, and debris, helping your HVAC system circulate cleaner air, maintain peak efficiency, and prevent premature wear caused by Charleston’s unique environmental conditions.
How often should I schedule professional duct cleaning for my home or business?
Most Lowcountry homeowners benefit from duct cleaning every 3–5 years. However, you may need more frequent service—every 2–3 years—if you have pets, allergy sufferers, recent renovations, or live close to marshes or construction zones that generate extra dust and pollen. Commercial facilities with higher occupancy or continuous operation should consider annual inspections and cleanings as needed to maintain indoor air quality and system efficiency.
What signs indicate that my air ducts need cleaning?
• Visible dust or mold on supply registers and return grills • Musty or stale odors whenever the HVAC system runs • Unexplained allergy or respiratory flare-ups among occupants • Uneven airflow or rooms that are harder to heat or cool • Excessive dust on furniture shortly after cleaning • Recently completed remodeling projects that produced drywall or sawdust If you notice one or more of these indicators, it’s time to schedule a professional duct inspection.
Will duct cleaning really improve energy efficiency and lower my utility bills?
Yes. Dust, pet dander, and microbial growth restrict airflow, forcing your HVAC blower motor to work harder. The U.S. Department of Energy estimates that 25–40% of the energy used for heating and cooling is wasted when ducts are dirty or leaking. After a thorough cleaning—and sealing if needed—air can move freely, reducing system strain, shortening cycle times, and potentially trimming 10–20% off your monthly energy costs.
Is the duct cleaning process safe for my family, pets, and HVAC equipment?
Absolutely. We use high-efficiency HEPA-filtered vacuums, negative-pressure containment, and eco-friendly sanitizing agents approved by the EPA for residential use. Flexible rotary brushes dislodge debris without scratching duct walls. All vents are sealed during service to prevent contaminants from entering living spaces. Our certified technicians follow NADCA (National Air Duct Cleaners Association) standards, protecting your HVAC components and ensuring a safe environment for children and pets.
How long does a typical duct cleaning service take and what should I expect?
Most single-family homes in Charleston take 3–5 hours, depending on square footage, number of vents, and duct condition. Larger homes or commercial properties may require a full day or multiple visits. 1. Arrival & inspection: We walk through your property, count vents, and assess duct integrity. 2. Setup: Drop cloths, corner guards, and negative-air equipment are installed. 3. Cleaning: Each supply and return line is agitated and vacuumed; the blower, coils, and drain pan are cleaned if included. 4. Sanitizing & sealing: We apply an optional antimicrobial treatment and re-install vent covers. 5. Final review: You receive before-and-after photos, efficiency tips, and a maintenance schedule. You can remain in the home during the process, though noise levels may be similar to a household vacuum cleaner.
