FAQs
Why should I have my air ducts cleaned in Charleston’s climate?
Charleston’s warm, humid conditions promote mold, mildew, and dust-mite growth inside ductwork. When your HVAC system cycles, these contaminants are blown into living spaces, aggravating allergies and respiratory issues. Professional duct cleaning removes built-up debris, sanitizes the interior surfaces, and helps your system deliver fresher, healthier air while reducing strain on the blower motor.
How often do experts recommend scheduling duct cleaning for Lowcountry homes?
The National Air Duct Cleaners Association (NADCA) suggests cleaning every 3–5 years, but Charleston homeowners may need shorter intervals because of coastal humidity, frequent pollen, and salt air. If you have pets, smokers, recent renovations, or family members with asthma or allergies, a 2–3-year cycle is usually best. Fresher Air technicians can inspect your system and tailor a schedule to your household’s needs.
What warning signs indicate my air ducts need professional attention?
Common red flags include visible dust puffs from supply registers, musty or moldy odors when the HVAC runs, uneven airflow, a spike in energy bills, or excessive dust settling on furniture shortly after cleaning. If you spot dark streaks around registers or hear rattling from debris in the ducts, it’s time to book a service call.
What steps are involved in Fresher Air’s duct cleaning process?
1) Pre-inspection with a high-resolution duct camera to document buildup. 2) Sealing of all vents and returns to create negative pressure. 3) Connection of a powerful, HEPA-filtered vacuum truck to the main trunk line. 4) Agitation with rotary brushes and compressed-air whips to dislodge dust, pet dander, and microbial growth. 5) Optional eco-friendly sanitizing treatment to inhibit mold and bacteria. 6) Post-inspection and customer walk-through with before-and-after photos for transparency.
Can duct cleaning lower my energy bills and improve indoor air quality?
Yes. When ducts are clogged, your blower motor works harder to push air, raising electricity consumption by up to 20 %. Cleaning restores proper airflow, often resulting in quicker cooling or heating cycles and lower utility costs. Removing allergens, mold spores, and dust also reduces airborne irritants, helping occupants breathe easier and potentially decreasing HVAC-related maintenance issues.
How long will the service take and will it disrupt my routine?
A typical single-system home in Charleston takes 2–4 hours to clean, while larger houses with multiple systems may require most of the day. Our technicians protect flooring and furniture with drop cloths, wear shoe covers, and keep doors closed as much as possible to maintain indoor comfort. You can remain in the home during service; only brief power interruptions to the HVAC system are needed while we work.
