Wondering when to call a trusted pro for indoor work is a common worry for homeowners. I’ve spent two decades serving Greenville, SC, and I handle every call personally at Array of Solutions. This guide explains How Often Air Duct Cleaning is recommended based on home size, pets, allergies, and HVAC usage.
Air ducts move heated and cooled air through your home. The National Air Duct Cleaners Association sets a baseline of three to five years, with some methods extending that span.
Look for visible mold, musty smells, pest signs, or puffs of dust from vents. These red flags mean schedule a service sooner to protect indoor air and system performance.
Clean ductwork through air duct cleaning cuts dust, improves comfort, and helps HVAC run less, which can reduce wasted energy and lower run times. If you’ve remodeled or moved in, don’t wait—book an inspection.

Key Takeaways
- NADCA recommends a 3–5 year baseline; some methods reach 6–8 years.
- Schedule sooner for visible mold, odors, pests, dust bursts, or post-construction.
- Regular service supports better air quality and HVAC efficiency.
- Simple DIY checks reveal problems before they grow.
- Array of Solutions offers personal, experienced care and clear next steps.
How to decide how often air duct cleaning is needed
Start with a standard interval, then tune timing to match your home’s needs and risks. NADCA sets a baseline of every 3–5 years, with some systems eligible to extend to 6–8 years when filters and vents are well maintained.

NADCA’s baseline and when to extend
Use the 3–5 years as your starting point. You may push to 6–8 years only if inspections show minimal dust and debris, and filters are replaced regularly.
When to shorten the timeline
Reduce the time between services if you have pets, known allergy or asthma issues, smoking indoors, wildfire smoke exposure, heavy dust, or a large household. These factors raise particulate load and strain your hvac system.
Move-in and post-construction
Always schedule a service when moving into an unknown prior home or after remodeling. Drywall dust, sawdust, and construction debris travel fast and can impair system components.
Upstate considerations
In Greenville and the Upstate, high humidity and seasonal pollen raise mold risk and lower indoor air quality. Combine dehumidification, timely filter changes, and a predictable maintenance plan to protect system efficiency and energy use.
- Start with NADCA’s baseline and personalize from there.
- Shorten intervals for pets, smoke, wildfires, or heavy dust.
- Schedule immediately for move-ins and post-construction.

Signs your air ducts need cleaning now
A few simple inspections can tell you whether the vents and ductwork are causing trouble for your home.
DIY checks you can run now:
- Remove a vent cover and shine a light inside. If you see layered dust or visible debris on the liner or seams, your air ducts likely need attention.
- Examine return registers and nearby walls for thick, fuzzy dust. That buildup often means restricted airflow and settled particulates in the system.
- Pull the filter. A clogged filter chokes the hvac system and lets dust bypass into trunks and returns.
- Open the furnace/blower compartment. Dust on fan blades or motor housings shows contaminants are recirculating.
- Check the A/C evaporator coil and cabinet for dust clinging to surfaces—this reduces heating and cooling performance.
Urgent red flags: visible mold or a musty odor, pest activity, puffs of dust from vents, or worsening allergy-like symptoms. Treat these as immediate reasons to schedule service.
I handle every inspection personally, document conditions thoroughly, and explain what they mean for your health, comfort, and system life. If work is needed, we use minimally disruptive methods and back our workmanship with a transferable warranty.

Air duct cleaning benefits and why choose Array of Solutions
Air duct cleaning removes built-up dust, debris, pet dander, and other contaminants that collect inside ductwork over time. Clean ducts help improve indoor air quality, reduce allergens, and support a healthier living environment—especially for households with asthma, allergies, or recent renovations. When airflow is unobstructed, HVAC systems operate more efficiently, which can lower energy use, reduce strain on components, and extend system lifespan. Many homeowners also notice more consistent temperatures and less visible dust after professional cleaning.
Choosing Array of Solutions means working with a company that focuses on real results, not shortcuts. Every job starts with an honest assessment to determine whether air duct cleaning is truly needed. Our process emphasizes proper equipment, thorough cleaning, and attention to HVAC system integrity to avoid damage or unnecessary upsells. With experienced technicians, clear communication, and a commitment to improving air quality—not just selling a service—Array of Solutions delivers dependable air duct cleaning you can trust.
When HVAC pathways are clear, the system runs shorter cycles and uses less energy while keeping temperatures steady. Cleaner ductwork reduces static pressure so your hvac uses less work to move conditioned air.
Removing dust, debris, and microbial contamination supports better indoor air quality and improved health for sensitive household members. Targeted work removes mold growth and musty odors at the source, which often restores comfort after remodeling or pet shedding.
Better HVAC system efficiency and lower energy use
- Efficiency gains: less resistance means lower energy consumption and fewer long run times.
- Extended life: reduced wear helps your system last longer and lowers unexpected repairs.
- Stable comfort: cleaner ducts deliver conditioned air evenly, cutting hot and cold spots.
Healthier indoor air quality
Thorough service limits dust recirculation and reduces allergens. The EPA notes indoor spaces can be several times more polluted than outside, so preventative maintenance matters.
