How long does flexible ductwork last?
What is the functional lifespan of a flexible duct system? A search of industry articles, blogs, and chat rooms indicates it lasts from 10 to 25 years. Most flexible duct manufacturers warranty their products for about 10 years.
What is the most commonly used ductwork in an HVAC residential system?
Made of galvanized steel or aluminum, rigid sheet metal is the most common type of ductwork. The thick, solid wall makes the duct very durable.
Is flexible ductwork insulated?
As I’ll discuss later, flexible ductwork is not only easy to install, it’s also easy to install wrong with kinks over trusses or electrical wires, too much length, or hard 90 degree bends. Insulating spiral ductwork more than doubles the price because the insulation is cut and glued between each of the spiral ribs.
Is it bad to close vents in unused rooms?
When you close the air vents in unused rooms, it’s much easier for the heat exchanger to crack, which can release deadly carbon monoxide into the home. Carbon monoxide is a tasteless, colorless and odorless gas that’s undetectable to humans.
How much does it cost to replace a flex duct?
The price you pay depends on the material: Flexible Polyester: $1-$4 per linear foot. Flexible Aluminum: $2-$5 per linear foot. Galvanized Steel: $3-$10 per linear foot….New Ductwork Cost Per Square Foot.
| Square Feet | Linear Feet of Ductwork | Price |
|---|---|---|
| 1,000 – 2,500 | 150 | $1,500 – $3,000 |
| 2,000 – 3,500 | 250 | $2,500 – $5,000 |
Is round or square duct better?
Round air ducts are best suited for high-pressure HVAC systems. Their design creates less friction, allowing air to flow easier throughout the building. Rectangular ducts aren’t as efficient with their airflow, which means they can create more harm than good in a high-pressure system.

Can you return air with flexible duct?
Yes! You can use flex ducts for your return ducts. However, you have to make sure it fulfills all the necessary criteria. These include pressure checks, proper wrapping, and marking, airflow control, etc.
Why is one room colder than the rest?
If some rooms are warmer or colder than others, this is usually just a matter of balancing. Meaning adjusting the airflow to each room so they all even out. If a room is heating or cooling much quicker than other rooms, the airflow can be reduced to that room to even things out, also sending more air to other areas.

Can We clean flex ducts?
Due to its delicate nature, flex duct should only be cleaned by a professional. The flexible ducts, or flex duct, found in the heating, ventilation, and air-conditioning (HVAC) system consists of three components. The outer layer is a polyethylene protective liner. The layer beneath the liner is fiberglass insulation.
What is a flexible duct connector?
flexible duct connector. In an air-conditioning system, a short length of flexible non-porous material that is inserted between metal ductwork and a metal air diffuser (or air register); prevents the transmission of vibration between these components of the system.
How to design HVAC ductwork?
Keep it tight. Design ducts so none of the runs have to travel too far to reach a room or area.
