Does duct cleaning really improve indoor air quality?

Duct cleaning improves air quality when ducts are actually the problem — visible buildup, biological growth, pest debris, or construction dust. In those homes, professional cleaning and sanitization removes the contaminant reservoir your blower redistributes every cycle. In homes with clean ducts, it does little.

Test First, Clean When It Counts

The honest approach is measurement before recommendation: inspect the ductwork, test the air, and clean only when cleaning will move the needle. Pairing duct cleaning with filtration upgrades and duct sealing delivers lasting results instead of a temporary fix.
