In the long term, sealing your air ducts can be a great way to keep your home energy efficient, save money, and provide many other benefits. Unfortunately, the connections between the air ducts can become loose or the ducts themselves can have cracks or holes. If the ducts are in poor condition (i.e., they have leaks or major holes), the cost of sealing them will be higher since the work will take longer. It can be hard to estimate exactly how much an air duct sealing project will cost, as it depends largely on the size of the house, the number of ducts present, and the severity of the leak.
In addition to using aluminum adhesive tape and sealing putty, insulation can be installed around the ducts to reduce any heat loss to the air surrounding the duct. Investing in duct sealing now is better than dealing with duct leak issues (such as poor indoor air quality and rising energy bills) in the future. If you answered “yes” to these questions, it's likely that the contractor has enough experience and seals high-quality ducts. This seals all air leak points in the system without damaging the mechanical components or sealing the ventilation grilles. Repairing or cleaning air ducts is cheaper than complete replacement, but it may not be enough. It's also a much more sustainable, long-term solution for sealing air ducts and guarantees that all air leak points are sealed, even in hard-to-reach areas.
Manual duct sealing methods cannot detect or seal leaks that are hidden in walls and other difficult places. Fortunately, a professional can help you determine how severe the air leak inside the air ducts is and identify the best plan of action to seal them. Additional repairs may be needed before or after installing the air ducts, either in the ducts themselves or in other aspects related to the installation. To replace the air ducts yourself, you will need metal sheets, hooks and straps, ventilation covers, duct sealant, insulation, and adhesive tape. More complex duct sealing jobs take longer (increasing labor cost), require more materials, and may even require special tools that cost more to operate. In conclusion, hiring a professional for your air duct sealing project is a wise decision that will save you time and money in the long run.
The cost of hiring a professional will depend on several factors such as size of your home, number of ducts present, and severity of leaks. However, investing in professional services now will help you avoid costly repairs down the line.
