An Ohio Bill, Senate Bill 338, requires registration and establishes laws governing the practices of air conveyance system cleaning services. It is not only Ohio, but other states as well, that have regulations aimed to protect consumers from dishonest duct and air conditioner cleaners.  Senator Kevin Bacon pushed for the law in Ohio.

Michigan already has a law requiring this as well.

Other laws specify the responsibility of landlords when it comes to ventilation in rented or leased buildings. In Oregon for example, the law says that it is the responsibility of landlords. ” Ventilating, air conditioning and other facilities and appliances, including elevators, maintained in good repair if supplied or required to be supplied by the landlord.”

Often, there are not specific laws regulating the cleaning of ducts, but renters can always contact the department of health or any renters advocacy office.

Usually, owners of buildings are responsible for cleaning of common areas and facilities, and this usually includes building’s ducts and vents. The state of Minnesota defines this as “compressors, ducts and in general all apparatus and installations existing for common use.”

There are laws governing ventilation and heating in Minnesota, and most states have similar laws. Just as building owners are required to install sprinkler systems, ventilation is required by law, and often cleaning is mandated.

There are plenty of  trade associations, like the Air Conditioning Contractors of America (ACCA), which produces standards for HVAC systems. ACCA also pushes for regulations and laws like this in more states. In the United Kingdom, the laws are already far beyond the US, enforcing regular cleaning and providing for inspection.
