Find Out How Duct Sealing Can Help You and Your Home
Our Team Provides Professional and Certified Duct Sealing Work for Your Home or Business
Basically, the air ducts in your home are tubes connected between the HVAC system and the air vents all over the house. Through an intake vent, the HVAC system pulls in the air and then either cools or heats that air.
The system will then force out that heated or cooled air through the ducts, and then through the air vents to warm or cool the house. It is important that the air ducts in your home are always clean and clear, so that the air that travels through the entire house is healthy and safe. However, if the air ducts are clogged and dirty, toxins can go through the house and your HVAC system may be driven to work harder and this may cause several problems.
Our Air Duct Sealing Services
Part of the air that circulates through the ducts can be lost because of holes, leaks, and bad connections. This can cause increase in your energy bills during peak winter and summer months. The HVAC system will also have difficulty in regulating the temperature throughout the house. Some of the common causes of ductwork problems include:
- Torn, leaky, or disconnected air ducts
- Leaks at filter slot and furnace
- Bends in flexible ductwork that restrict the airflow
- Poorly sealed grills and registers
A common solution to these problems is to have the air ducts properly sealed and insulated. There are many benefits of air duct sealing, including:
- Improved indoor comfort
- Better indoor air quality
- Increased energy efficiency and energy savings
- Improved safety
When you work with Phoenix AC & Heating Experts to seal your air ducts, out team will inspect the entire ductwork system to properly determine the supply and return air balance of your HVAC system.
Why Get Your Air Ducts Sealed and Re-Sealed
You probably do not think about your air ducts often, but they need regular service like other systems in your house. Ducts can easily develop leaks, whether from improper installation or normal wear and tear. Individual leaks may be small, but they usually add up fast. According to the US Department of Energy, the air climate control system loses 20-30% of its total output due to duct leaks. This means a percentage of your payment for heating or cooling the house goes to waste. To prevent these losses, our contractors can get your ducts inspected and sealed as necessary.
Two Popular Methods of Duct Sealing:
A. Exterior sealing – many contractors seal ducts by hand using mastic, a non-hardening, gooey material. Before they seal the seams with mastic, they usually secure the joints using metal screw.
The mastic can be spread over the duct seams using a putty knife or disposable paintbrush. Some simply spread mastic using their fingers while wearing gloves.
B. Interior duct sealing – Aeroseal is a process of duct sealing that usually uses advanced equipment and technology. It is a computerized method of applying an aerosol sealant on the interior of the air ducts where it finds and seals the leaks.
Aeroseal is designed to meet strict standards for duct leaks in new buildings and repair leaks in ventilation shafts and air ducts of existing buildings. Studies find it to be 60% more effective compared to manual sealing. Moreover, the labor and repair expenses are 30% lower.
Typically, Aeroseal equipment is connected to ductwork through a long, flexible tube that runs from the duct to the equipment. In setup process, the vents connected to the ductwork will be closed temporarily so that the air that inside the ducts could only escape through leaks. Our team uses the Aeroseal computerized equipment to determine the precise amount of leakage before we begin the sealing.
Once ready, we use the equipment to deliver an aerosol mist of sealing particles inside the ductwork. While the holes are being filled, there is a computer monitor that provides information of the leakage rate.
What is the Typical Cost of Duct Sealing?
Duct sealing your home or business in Phoenix, AZ will save you a lot of money in the long run. The average cost of duct sealing is from $1,500 to $2,500 per air conditioner. However, remember that there are many different factors that determine the final cost, such as size of the house, age and location of duct system, and method of sealing.
Every property in Phoenix is different, so we can only tell you the exact cost for a certain job if our licensed contractors come to your house or business to provide you an estimate.

If you’re frustrated at the apparent inefficiency of your HVAC system, it’s important to know that the culprit may not be in the machinery. In fact, you could have a perfectly efficient air conditioner and furnace but still have issues with efficiency if your ducts are not properly sealed.
Duct sealing is part art and part science, and it results in a system of well-insulated and sealed ducts that efficiently deliver air throughout your home. If this sounds like an upgrade your ducts could use, keep reading to learn more about the process involved.
What is the Average Cost to Seal Your Air Ducts
Unlike other HVAC repairs, the average cost of air duct sealing depends largely on the existing infrastructure. For an average job, though, you can expect to pay anywhere from $1,000 to $2,500. The large range of average costs reflects the reality that no two jobs are alike, meaning it’s best to have a technician stop by to give you a more accurate estimate.
Factors That Affect the Cost of Duct Sealing
Factors that determine the cost of a duct sealing project include the size and age of the ductwork, the size of your home, the accessibility of the ductwork, and how the ductwork is currently sealed and insulated. Here is a more detailed explanation of some of these factors.
The first and most important factor that determines the cost is the size and age of your ductwork. A sprawling system of ducts that are retrofitted to an older home will be quite complicated to seal and insulate properly, thus raising the cost. On the other hand, a smaller home that was built recently and still has most of its ducts exposed will be lower in cost.
To add to this point is the fact that dual HVAC systems typically double the cost involved in duct sealing. Since each system of ducts is separate from the other, each has to be treated as its own individual project. Given the benefits of duct sealing, though, this increased cost is well worth it.
As mentioned, the accessibility of the ductwork also plays an important role in determining the price of a duct sealing project. If your home’s ductwork is located in an unfinished attic or basement, then it is a prime candidate for duct sealing. This is because, in addition to being easy to access, these exposed ducts are in desperate need of insulation to improve their efficiency.
This idea of exposed ducts overlaps with the last factor determining duct sealing cost, and that is the current status of your ducts when it comes to sealing and insulation. If your ducts are neither sealed nor insulated, the project cost will be higher than if the joints of your ducts are already sealed.
Alternatively, if your ducts have been previously sealed and insulated, but those measures have become worn out, then it will cost more to remove the old insulation, clean the ducts, and install new materials.
How Long Does Duct Sealing Take?
In an ideal environment, the average duct sealing job takes about two hours. This refers exclusively, however, to putting mastic sealant on the duct joints and allowing it to dry. Additionally, this assumes that the ducts are easily accessible and that no other extenuating circumstances present themselves during the course of the project.
Beyond these foundational factors, most of the same factors that influence the price of a project also determine its longevity. Obviously, larger, harder-to-access ducts will take longer to seal properly than easy-to-access ducts in a small home. Additionally, it’s a good idea to have your ducts sealed in a secondary manner, which is also called insulating your ducts. In insulation, plywood or foam is used to isolate the soffit where the ducts are located from the rest of the surrounding space.
This is especially important if your ducts are in an uninsulated attic or basement, as the ducts need to be protected from extreme temperatures in order to allow your HVAC system to work efficiently. If you desire to have your ducts sealed in this manner, along with the basic sealing of joints, then this will add significant time to the project.
What are the Benefits of Duct Sealing?
Duct sealing helps your HVAC system to operate more efficiently in a variety of ways. Two key components of duct efficiency are a duct’s ability to move air from place to place without being interrupted and a duct’s ability to minimize energy transfer with the surrounding air, meaning you don’t want them to transfer heat or cold until the air gets to the room you are trying to heat or cool. Duct sealing helps with both of these things.
When it comes to uninterrupted airflow, duct sealing helps by filling in the gaps that are present at each joint in the ducts. As air flows through the ducts, these joints can allow air to escape, which can reduce the overall heating and cooling capacity of your HVAC system. If the joints, and any other holes, are sealed, however, then all the air that leaves the central HVAC system will arrive at the vents.
As far as minimizing energy transfer, duct sealing helps prevent unconditioned air from the cavities where ducts are located from entering into the ducts. Since air of different temperatures seeks to mix until it reaches equilibrium, the unconditioned air outside the ducts and the conditioned air inside the ducts are at risk of mixing, thus lowering the efficiency of your HVAC system. If the ducts are sealed, however, this mixing is much less likely, meaning your home will be heated and cooled much more quickly and efficiently.
