How should a residential HVAC system be cleaned?

The most effective way to clean air ducts and ventilation system is to employ Source Removal methods of cleaning. This requires a contractor to place the system under negative pressure, through the use of specialized, powerful vacuum. While the vacuum draws air through the system , devices are inserted into the ducts to dislodge any debris that might be stuck to interior surfaces. The debris can then travel down the ducts to the vacuum, which removes it from the system and the home.

What kind of equipment is best for cleaning-Truck-Mounted Vacuums or Portable vacuums?

NADCA does not endorse one kind of equipment over another. There are two main types of vacuum collection devices: (1) those mounted on trucks and trailers, and (2) portable units. Truck Trailer mounted equipment is generally more powerful than portable equipment. However, portable equipment can be brought directly into a facility, allowing the vacuum source to be located closer to the ductwork. Both types of equipment will clean to NADCA standards. A vacuum collection device alone will not get an HVAC system clean. The use of methods and tools designed to agitate debris adhered to the surfaces within the system, in conjunction with the use of the vacuum collection device(s), is required to clean HVAC systems. (For example: brushes, air whips and "skipper balls.")
