If you’ve spent any time in local Facebook groups, you’ve probably seen a few “too-good-to-be-true” ads for $99 air duct cleanings—often followed by skeptical comments and scam warnings. While these companies and services may not always be an outright scam, it’s fair to ask: is air duct cleaning a real service, or just a modern myth?
Truthfully, having your air ducts professionally cleaned can offer real benefits when done for the right reasons. It’s not something every home needs all the time, but in certain situations, it might be worth considering.
What Does Air Duct Cleaning Actually Do?
Over time, your home’s ductwork can collect a surprising mix of dust, pet hair, pollen, and even mold spores. A professional air duct cleaning service can help remove this buildup and prevent it from circulating through your home. A typical service might include:
- Removing dust and debris by vacuuming or brushing
- Cleaning the supply and return vents
- Inspecting and cleaning HVAC components like fans and coils
- Looking for signs of pests, blockages, or mold
Duct cleaning is not a cure-all, but when there’s visible buildup or specific concerns, a thorough cleaning can support better air quality.
When Air Duct Cleaning Might Be Worth It
While routine duct cleaning isn’t typically necessary, there are valid reasons to invest in it.
- Excessive Dust or Allergies – Constant dust buildup or ongoing allergy symptoms may point to ductwork circulating irritants. If you notice excessive dust buildup around vents, frequent allergy symptoms, or worsening asthma indoors, your ductwork may be circulating allergens.
- Mold Growth – Mold inside ducts isn’t just unsightly—it can affect your health. Cleaning helps, but solving the underlying moisture issue is just as important.
- Pest Infestation – Evidence of rodents or insects (like droppings or nests) in your ductwork is a clear sign that a cleaning is in order.
- Recent Renovations – If you’ve had major construction work done in your home, dust and debris may have settled in your ducts.
When It Might Not Be Necessary
For many households, regular filter changes and routine HVAC maintenance are enough to keep things running smoothly. If there’s no sign of mold, pests, or performance issues, professional duct cleaning likely won’t make a noticeable difference. If you do need your air ducts cleaned, your HVAC contractor may already offer it as a service.
How to Keep Your Air Ducts in Better Shape
Want to keep your air ducts in top condition? Try these tips:
- Change HVAC filters regularly – Replacing your HVAC filter every 1–3 months helps keep dust and debris out of your ductwork.
- Seal duct leaks – Leaky ducts can draw in dirt and contaminants from crawl spaces or attics. Having them sealed can improve efficiency and air quality.
- Control humidity – Keeping indoor humidity in check (between 30–50%) helps prevent mold growth inside ducts, which may require remediation or replacement.
So, is air duct cleaning worth it? In some cases, yes—especially if you have mold, pests, or significant dust buildup. But for many homeowners, routine HVAC maintenance and good indoor air habits can keep ducts clean without the need for cleanings. If you’re unsure, a professional inspection by an HVAC professional can help determine if your ducts truly need attention. As always, doing a little research and choosing a trusted local service can make all the difference.
