Air duct cleaning for an average-sized home costs $300–$600 in the US, with most homeowners paying around $400. The EPA notes that duct cleaning has not been shown to prevent health problems in every case, but it's worthwhile after renovations (drywall dust), mold discoveries, pest infestations, or when moving into a new home. The HVAC industry recommends cleaning every 3–5 years for most homes, or more frequently if occupants have allergies or pets.

Duct cleaning costs in Poland
In Poland, duct cleaning costs PLN 500–2,000 for a residential system. Central HVAC with ductwork is less common in Polish homes (most use radiators), but modern apartments with mechanical ventilation (rekuperacja) need duct cleaning every 3–5 years. Cleaning a rekuperator unit with ducting runs PLN 500–1,200. Commercial duct cleaning is a larger market, regulated under building fire safety codes.
What affects the cost?
- Home size — more square footage means more duct runs and vents
- Number of HVAC systems — multi-zone homes cost $200–$400 more per system
- Contamination level — post-renovation dust, mold, or pest debris costs more to clean
- Access difficulty — crawl spaces, attics, and multi-story homes add labor time
- Add-ons — sanitizing, mold treatment, and dryer vent cleaning increase the total
