What affects your air duct cleaning price?
- Number of vents/registers — more supply and return vents means more labor.
- Home size & number of systems — a second HVAC unit roughly adds another system’s worth of work.
- System access — hard-to-reach ducts, attics, or crawlspaces take longer.
- Level of contamination — heavy debris, pet dander, or mold may require extra treatment.
- Add-on services — bundling dryer vent cleaning or sanitizing.
Why “$99 air duct cleaning” is usually a scam
Ultra-low “whole-home” prices are typically a “blow-and-go” — a quick once-over used to upsell you on site, not a real source-removal cleaning. A thorough job uses negative-air equipment and takes hours. If a quote seems too good to be true, ask exactly what’s included and whether they follow NADCA/EPA practices.
