Clean Air
for a Clean Home

Did you know the quality of the air in your home can be much worse than the air outdoors? In fact, the EPA lists indoor air quality as one of the top five health threats in America, and there is a long list of potential allergens and pathogens in your ductwork.

Zerorez® Madison uses a negative air system by Hypervac Technologies. This "Push-Pull" method is the Gold Standard in duct cleaning. We use compressed air and agitation tools/whips at the vent to break loose dust and debris which is simultaneously being pulled down by the suction of the Hypervac vacuum. Negative air is the best way to help ensure the dust and debris being removed stay contained in a filtered recovery unit vs. swirling back into your home.

This system is designed to service single-family residential homes. We are not currently cleaning commercial properties, or multi-story apartments or condo complexes.

  • We'll need access to the supply and return trunk lines ( the two large ducts running to and from the furnace) to be able to clean. Our negative air unit is about 5ft x 3ft wide. Please clear a path to, and around, the furnace prior to the service. If your furnace room can't accommodate this size, please call our office.
  • The furnace/AC will need to be shut down while the duct cleaning is performed, so please make sure to heat/cool your home to the desired temperature prior to the service.
  • Please remove anything that may obstruct access to the air vents in each room.


Breathe the Difference:
Stay Healthy

As many as 1 in 5 Americans suffer from allergies caused by particles that are frequently found in the air inside most homes. If you or anyone in your family suffers from allergies or asthma-or if you just want healthier air in your Madison Area home-Zerorez® can help.

Ducts can carry harmful particulates and promote asthma, hay fever, and allergy symptoms. A clean duct system promotes a healthier indoor environment, which contributes to productivity, comfort and a sense of health and well being.
