Air conditioner ducts are pathways that carry chill air from the air conditioning unit towards the home. The air supply can be either heated or cooled by the HVAC system. AC ducts are usually present within the floor, wall, and ceiling frame.
Since these ducts are present within the basement, they usually get damaged near the exposed areas. Damaged ducts can lead to leakage, which can further cause a severe breakdown in the future. In such cases, replacing them can be lifesaving. Read this article to find out everything relating to the air duct replacement cost.
How Do Air Conditioner Ducts Work?
Air conditioner ducts contain tubes that are connected to HVAC systems. First, the surrounding air is pulled in through the HVAC systems that is either cooled or heated.
Next, the air is forced outside the vents to cool or heat the house. Air ducts function similarly to capillaries or arteries. If the veins are clean enough, the blood circulates evenly and smoothly throughout the body, providing the nutrition it requires.
Similarly, the HVAC ducts force cold or hot air throughout the vents and into the house. If there is an unclean air supply, the AC ducts might get damaged over time. In addition, polluted air can clog the HVAC ducts, causing them to work harder.
This can impair their durability and push the HVAC system to shut down constantly. In addition, it is imperative to replace your air duct systems once they get damaged, or else they could cause an electricity breakdown and pose a severe risk to your safety.
Types of Ductwork Material & How Much Does It Cost
Aluminum is known to be one of the best materials used in air ducts. This is probably because of the excellent insulation properties it offers.
Moreover, aluminum is affordable, lightweight, and extremely easy to install. Aluminum ductwork can cost around $6 to $12 per linear foot.
Fiberglass duct liners are used in several ventilation, heating, and cooling units. They are an excellent material for ducts as they provide thermal insulation, preventing them from losing valuable conditioned air.
Fiberglass ducts are sheet metal ducts with internal and external lining. People usually complain about the loud sounds HVAC systems make, which fiberglass ducts are best known to dampen.
This is why they are primarily used in commercial settings. They cost between $6.50-13.50 per linear foot.
Flexible ducts are a very convenient option for homeowners. These are long ductwork pipe-like tubes that flexibly fit in bizarre home spaces.
In addition, they can be combined with other rigid ductwork to produce a tremendous overall HVAC ductwork.
Moreover, they are pretty inexpensive. They cost between $2 to $5 per linear foot.
What Affects The Cost Of AC Duct Replacement?
The location of your home is a critical factor in determining the HVAC duct replacement cost. If you avail of the services of duct replacement professionals who are established quite far away from your residence, you will have to pay the delivery and travel fees as well.
The size of the job is also a critical factor in indicating the AC duct replacement cost. Most professionals charge per linear installation foot, while some tell you an estimated cost including the number of ducts used. If you live in a bigger house, your project may require more ductwork, hence, more costs.
The type of ductwork used is a huge factor that impacts the duct replacement cost. Although sheet metal is the most durable duct material, it is also the most expensive to install. On the other hand, flexible ducting is the most convenient and affordable duct material, but it is not widely used because it’s less durable.
If you live in a house with bizarre installation spaces, installing ductwork in your home space will require more effort.
This will eventually increase the cost of installing ductwork. In addition, if your ductwork spaces are located behind walls or inside floors, accessing them will be challenging and require more time and effort.
Your contractors will need to cut through walls and ceilings to access the ductwork, which will increase the project’s overall cost.
How Much Is The Average Cost To Replace The AC Duct?
|Square Feet Of House||Average Cost of Replacement|
|1000||$3,000 – $6,000|
|1500||$4,000 – $7,000|
|2000||$5,000 – $9,000|
|2500||$6,000 – $10,000|
Replacing Ductwork In Crawl Space
The price of replacing ductwork in a crawl space usually lies around $12 to $30 per linear foot. If the area is clean and easy to access, the price will be minimal.
If it’s not, additional costs may include cleaning and repairing the crawl space itself. The cleaning and improving the crawl space is around $6000, while installing one will be about $5500.
Crawl spaces are usually a more tough place where ductwork replacement is concerned, thus more costly.
Replacing Ductwork In Attic
The price of replacing ductwork in an attic costs lies around $500 to $2000. This usually depends on the size of your house attic and the HVAC system.
If you want your HVAC system to be more efficient, installing attic insulation can be a great option. However, the installation will cost around $1700 to $2000.
Moreover, attics can be small and have lots of clutter, so one should ensure it is easy to access if one wants the cost to be lower.
Replacing An Exposed Ductwork
Several homeowners prefer installing AC ductwork that is concealed to prevent external damage.
However, replacing concealed ductwork is pretty expensive. Several people prefer installing a ductwork system that is exposed as it looks more appealing.
In addition, replacing exposed ductwork will cost less as it removes the price of patching walls. Moreover, on average, depending on the home’s size, replacement costs between $1,400-5,600.
Repair Vs. Replacement Cost
A comfortable HVAC system ensures consistent heating and cooling throughout the year. Homeowners often fail to realize how important every part of the HVAC system is. Issues inside the AC duct systems can lead to inefficient functions. A weak HVAC system can lead to a waste of energy and higher bills.
In these cases, it is essential to either repair the ductwork system or have it replaced right away. When replacing or repairing the ductwork, it is vital to consider the costs. Most homeowners think improving the AC duct system is less costly than replacing it.
This may seem beneficial but can be very expensive in the longer run. The price of repairing or replacing your duct system varies. The cost of repairing ductwork lies between $400 to $700. If the tears are more minor, homeowners can do it themselves, but professional help is better.
The cost of replacing ductwork is around $30 to $70 for every linear foot. This highly depends on the condition and size of the space of the installation. If you have more extensive ductwork, replacing it may seem expensive, but it is way more efficient in the longer run. Spending time and money on repairs repeatedly can cost you a fortune. Hence, it is better to invest in an efficient AC duct system once and for all to prevent any further maintenance and repair costs.
