Questions about duct cleaning

  • When does duct cleaning actually help?
    When ducts are visibly dirty, when remodeling debris is in the system, after rodent intrusion, or when occupant allergies/asthma haven't responded to filtration alone. We don't push it on every visit — most homes don't need it.
  • Why before/after photos?
    Duct cleaning is a hard sell because the customer can't see inside the system. We document with borescope photos at the same spots before and after. The difference is usually obvious.
  • How long does the job take?
    A typical 1,800-2,400 sq ft home runs 3-5 hours, single crew. Larger homes or homes with extensive trunkline work can stretch to a second visit.
