Duct Cleaning

Professional cleaning of HVAC ductwork to remove dust, debris, allergens, and mold from air distribution systems

💰 $300–$700 for residential systems ⏱ 3–5 hours for a standard residential duct cleaning ⚡ Moderate — every 3–5 years or as needed

⚠️ Warning Signs You Need Duct Cleaning

  • ⚠ Visible dust or debris blowing from supply registers when the system turns on
  • ⚠ Musty or moldy smell from vents that persists even after filter replacement
  • ⚠ Allergy or respiratory symptoms at home that improve when away — may indicate mold or allergen accumulation in ducts
  • ⚠ Pest or rodent infestation in the home — animals can nest and die in ductwork
  • ⚠ More than 5 years since the last duct cleaning, especially in dusty Sunbelt climates
  • ⚠ Recent home renovation — construction dust contaminates ductwork extensively
  • ⚠ Visible mold or discoloration on visible duct sections near registers

What to Do: Step-by-Step

  1. 1 Verify the contractor uses a truck-mounted or high-powered portable vacuum system with HEPA filtration
  2. 2 Confirm they clean both supply and return ducts, not just the supply registers
  3. 3 Ask for before-and-after photos of the ductwork interior — reputable cleaners provide these
  4. 4 Check if mold testing is included or if it's an add-on service
  5. 5 Have the blower wheel, evaporator coil, and air handler interior cleaned at the same time for maximum benefit
  6. 6 After cleaning, replace the air filter before restarting the system
  7. 7 Ask the contractor to seal any duct leaks they find during cleaning — duct sealing can reduce energy bills by 10–30%
