A Century of HVAC-R Progress: 30+ Years of Rotobrush Innovation

This piece is a product announcement from Rotobrush, a maker of air duct cleaning equipment, marking more than 30 years in the business. It doesn't carry news that changes what homeowners should expect to pay or qualify for, but it's a useful reminder that duct cleaning is a service some HVAC contractors offer using specialized machines like these.

The company makes two main types of equipment. One is a brush-and-vacuum system that physically scrubs the inside of ductwork while vacuuming out debris, useful for jobs in attics, basements, and crawlspaces. The other uses "negative air" cleaning, which pulls air (and dust) out of the ducts using strong suction rather than brushes, delivering high airflow for tougher jobs. Both come with removable components contractors can carry into tight spaces, cutting down on long hose runs.

For a homeowner, none of this changes your own to-do list. Duct cleaning isn't something you'd do yourself, and this article doesn't mention any rebate, program, or new rule tied to it. If your ducts haven't been cleaned in years, or you're doing other efficiency work on your home, it's simply worth knowing that contractors have more capable, portable equipment now than in the past for that kind of job.
