Air Duct Cleaning in St. Augustine, FL

Florida's heat, humidity, and year-round AC use pack residential ductwork with dust, pollen, pet dander, and mold spores faster than almost anywhere else in the country. Our whole-home air duct cleaning uses a truck-mounted HEPA negative-air vacuum and rotary agitation to pull years of buildup out of every supply and return run — then we send you photos of every register, before and after.

Bastion Duct Solutions provides air duct and dryer vent cleaning to homeowners across St. Augustine and all of St. Johns County — from historic downtown and Lincolnville to Nocatee, SilverLeaf, World Golf Village, Ponte Vedra, and St. Augustine Beach. Coastal salt air, 75%+ summer humidity, and constant AC runtime turn dust into a sticky biofilm inside St. Augustine ductwork in as little as 18 months. We use truck-mounted negative-air HEPA vacuums and NADCA-style agitation on every job, with optional EPA-registered antimicrobial fog treatment to kill mold spores left behind by Florida humidity.

Our process in St. Augustine

1. Camera Inspection: We scope every supply and return run with a borescope camera so you see exactly what's in there before any work starts.
2. Protect the Home: Drop cloths, corner guards, and shoe covers. We treat your home like our own.

Our whole-home air duct cleaning starts at $299 for up to 10 vents, with each additional vent at $25. Most St. Augustine homes fall in the $299–$499 range. Avoid '$59 whole-house' coupon scams — they almost always upsell into the thousands on-site.
