How much does it cost to install ducts in an unfinished home?
The cost of installing ducts in an unfinished home averages $1,900 to $4,000. In new construction, installing new ducts is fairly straightforward because the ducts can be put in before the walls and floors are finished, making the installation easy. If the home will have ducts, space can be left for them, which makes installation easier. In a finished home, there is often no space for the ducts, making it costly. But in an unfinished home, the ducts can be planned from the beginning. This means you can have a more efficient and optimized system, with ducts that are large enough to handle more air than may fit in an existing home.
Why are ducts hidden in the basement?
It is common for homes to have at least some exposed ducts in the basement or utility room because they move from your HVAC system to the finished rooms of your home. From there, the ducts become concealed in floors, walls, ceilings, closets, and other spaces. In some homes, such as lofts, all the ducts may remain exposed. The cost of installing new ducts fluctuates depending on whether the ducts are exposed or hidden. Hidden ducts are harder to reach, increasing labor costs.

The trunk is the area that connects directly to the HVAC and runs to all the branches, which then feed off to the vents. Fiberglass ducts are insulating and can be used to gain LEED credits in some areas.
What are the different types of ductwork?
It is very common for some installations to use more than one duct type. Two of these are flex ducts and metal ducts. Metal ducts make up the trunk of your ductwork. They are what attach to your HVAC system and begin the run to the many branches that will carry the air to the rest of your home. From there, the branches may be made of flexible materials, including aluminum and some types of insulated, recycled plastics. Flexible ducts are good for fitting into narrow areas, bending around corners and obstacles, and feeding through joists. Metal ducts are good for handling larger amounts of airflow at once. In most cases, you will find that your ducts need a combination of both to work efficiently.

It can be of many different duct types and forms. This depends on whether this is a branch or the main trunk of your line.
What is a supply duct?
Supply ducts blow warm or cool air to an area inside a home. Supply vents often have dampers to control the flow, called registers . Supply registers will often be installed near windows or doors to better counteract the loss of heat or cold, and two supply registers may be installed in larger rooms to evenly distribute the HVAC air.
How much of the air in ducts is escaping?
Up to 30 percent of the air in your ducts may be escaping.

You may eventually discover through a utility usage report that you are using way more electricity than other similar homes in your neighborhood.
What is flex duct?
Simply put, flex ducts are made from a steel wire spiral, wrapped with a polymer (a bendable plastic), and surrounded by insulation. This kind of ductwork is inexpensive, lightweight, and easy to install. Flex ducts work wonders in tricky spaces where more rigid ductwork will not do.
What happens when air collides with ductwork?
Just like the airplane that vibrates within air pockets, air colliding with the duct becomes turbulent and moves slower. A good HVAC specialist will avoid unnecessary bends when installing the HVAC duct system and opt for smaller tree branch type ducts where possible.
Where does HVAC get its air?
Contrary to popular belief, HVAC systems get their air from inside the building. Return ducts extract air from the living spaces back to the HVAC unit, feeding either your furnace or air handler. Return vents are usually larger than supply vents and are called grills. A filter is often installed either deep inside a return duct or right at the return grill to protect your HVAC unit from impurities.
Do air ducts last forever?
Just ask the cow in twister. Your airducts experience wear and tear over time when air is ricocheting off the walls, so unfortunately, they don’t last forever. Expiry dates vary – metal ducts generally last longer than flex ducts because metal is more rigid and its surface allows air to glide, unlike the coil around flex ductwork. That said, the average air duct lifespan varies from 15 to 25 years. ( Air Duct Lifespan)
Can old flex ducts corrode?
Old seals will erode with enough wear and tear, letting air slip out (or in). If moisture gets into the air duct, it will corrode over time. You’ll see the same corrosion if your basement or crawl space is overly humid, or if water is leaking from your roof, plumbing, or humidifier. Unsupported flex duct runs are more likely to sag, and condensation will gather in the dip.
