Ducts made of ACM’s Ducts which are made of ACM are much less common than metal ducts wrapped with ACMs. If a duct is made of ACMs and it is punctured or damaged, then asbestos fibers may be circulating in the air.
Is Air Duct cleaning a ripoff?
Duct cleaning has never been shown to actually prevent health problems. Neither do studies conclusively demonstrate that particle (e.g., dust) levels in homes increase because of dirty air ducts. This is because much of the dirt in air ducts adheres to duct surfaces and does not necessarily enter the living space.
How do you know if you need new duct work?
The best way to know if your air ducts need replaced is through a duct blower test. An HVAC technician will install pressure sensors in your home’s air ducts, then use a blower fan to pressurize the ducts. An air flow sensor in the blower calculates how much air is required to maintain the pressure.
Can you clean insulated ductwork?

Is fiberglass duct liner safe?
Fiberglass, at a minimum, is an acute physical irritant to the skin, eyes, and upper respiratory tract. While no long-term health effects should occur from touching fiberglass. Rashes can appear when the fibers become embedded in the outer layer of the skin.
How can you tell if ductwork is asbestos?
Asbestos duct insulation: white “paper” wrapped on outside of some heating ducts. Asbestos pipe insulation: white corrugated insulating material on and hanging from pipes, white paste material surrounding certain plumbing joints.
What is Transite ductwork?
Transite ducts consist typically of 10- to 12-inch round PVC tubes or pipes that run under a concrete slab in the ground to provide heating and cooling to a house. Typical transite, or “in-slab” ductwork consists of a single long tube that runs the perimeter, along the outside walls.

Transite pipe used as HVAC ducts or air ducts for heating and air conditioning was often installed buried in a concrete floor slab – methods that placed the asbestos-cement transite piping below or in a building floor slab.
Do transite in-slab HVAC ducts have asbestos?
Photo and some of our comments on transite in-slab HVAC ducts are provided courtesy of Roger Hankey, a Minnesota home inspector. Asbestos hazards of transite ducts: Cementious duct material may contain asbestos. What is this “cement” duct work made of Cement and asbestos fibers.
What are the hazards of Transite (cement asbestos) air ducts?
This article explains the potential hazards of transite (cement asbestos) air ducts – asbestos fiber release, radon, and indoor air quality concerns, and duct collapse when transite air ducts are is found in buildings. Transite pipe, an asbestos-cement product, was used for HVAC ducts and for chimney or flue material to vent gas-fired appliances.
What happens if you cut transite pipe?
If transite pipe is damaged or is cut mechanically (such as by using power equipment), friable, airborne asbestos fibers may be generated – a health and costly cleanup concern.
