What Happens During a Professional Air Duct Cleaning?

Certified technicians follow NADCA’s source-removal method:

• System examination — Technicians open access doors and take photographs of the conditions and cover floors with drop cloths.

• Negative-pressure setup — In a negative pressure setup, the ductwork is connected to a high-powered vacuum truck or a portable HEPA unit. This creates constant negative pressure in the system, making sure that any dislodged debris is pulled out and doesn’t spread into the occupied areas.

• Mechanical agitation — Rotating brushes, compressed-air whips and skipper balls clean supply and return runs on both sides of the register and back to the air handler.

• Collection and containment — Fine particles and larger debris are carried to the containment unit of the vacuum to be discarded.

• Component cleaning — Coils, blower blades, drain pans and registers are cleaned and disinfected when necessary.

• Final walk-through — The team seals holes of access, replaces filters, and demonstrates pre- and after-shots, to ensure the results.

The average house in the Austin area (single HVAC system, 1,600 to 2,000 square feet, approximately 10 to 15 supply outlets) will require two to four hours. Big commercial work may entail night or weekend crews and several days of work.

Deep cleaning done professionally under negative pressure and confirmed with photos is much better than any DIY system. That’s where IAQ Austin — Air Duct Cleaning comes in — providing expert service you can trust to get the job done right.
