Ductwork, Cleaning & Airflow

Expert duct cleaning removes mold, dust and bacteria from the inner lining of your ducts, and sealing keeps the air you paid to cool inside your house.

What we see in the field

In attics across the county we find crushed flex at the boot, sagging runs holding standing dust, and disconnected takeoffs dumping cold air into insulation. Cleaning is worth doing, but on any system past a decade we check for leakage first. Sealing a duct system almost always returns more comfort per dollar than cleaning it.

Ductwork is the part of the system nobody looks at, which is why it causes so many problems. In Florida attics, ducts sit in 130°F air and pull humid, dusty attic air through every loose joint. A typical leaky duct system loses 20–30% of the conditioned air it carries before it ever reaches a room.

Duct cleaning

We use industry-leading RotoBrush tools that scrub the inner lining while vacuuming debris out, not a hose stuck in a vent. The result is cleaner, fresher, safer air and a system that isn't recirculating whatever settled in the ducts over the last decade.

Sealing, redesign and replacement

  • Leak testing to find where the conditioned air is going
  • Mastic sealing at plenums, boots, and branch takeoffs
  • Manual D duct design for new systems and additions
  • Replacement of crushed, disconnected, or undersized runs
  • Return-air additions to fix rooms that never get cool

When to have ducts cleaned

  • Visible mold or dust blowing from supply registers
  • A musty smell every time the system starts
  • After a renovation, roof leak, or rodent activity in the attic
  • Rooms with noticeably weak airflow compared to the rest of the house
  • Every 3–5 years in humid coastal homes as general maintenance

Common questions

How long does duct cleaning take?
Most single-family homes take three to five hours depending on the number of runs and attic access.
Is cleaning the same as sealing?
No. Cleaning removes what's inside the ducts; sealing stops leakage. Homes with high bills usually need sealing, and often both.

  • Kimberly McCarthy
    Great experience. Had problems with a dryer vent 9 months ago, Sunshine came out and cleaned the vent. It started acting up again. Sunshine came out, found that the screen on the roof had clogged again. Fixed it at no charge.
