Do Air Ducts Need to be Sealed? A Comprehensive Guide to Energy Efficiency

To guarantee that your home or commercial building is energy-efficient and cost-effective, it is essential to seal the air ducts along the entire length of the duct system. Poorly sealed air ducts can cause a significant loss of energy and money, particularly in larger buildings. On the other hand, well-sealed air ducts can reduce energy consumption and provide a number of other advantages. In this article, we will discuss why air ducts need to be sealed, the benefits of doing so, and how to go about sealing them.

The most obvious benefit of sealing air ducts is that it decreases energy consumption. When air ducts are properly sealed, the air conditioner will reach the intended room without leaking into the attic and forcing the air conditioning system to work harder than necessary. This can result in lower energy bills and improved efficiency. In addition to reducing energy consumption, sealing air ducts can also improve indoor air quality. Poorly sealed ducts can allow combustible gases to enter your home, as well as dust, insulating particles, and other outdoor contaminants.

Sealing your air ducts can help prevent these harmful substances from entering your home. Another benefit of sealing air ducts is that it can help protect your home from damage. Poorly sealed air ducts can cause moisture to build up in walls and ceilings, leading to mold growth and structural damage. Sealing your air ducts can help prevent this from happening. The best way to seal air ducts is to hire a professional to do the job internally. This ensures that all of the ductwork is properly sealed and that no leaks are left unchecked.

However, if you have accessible ductwork and you're comfortable with DIY projects, you can buy putty and seal the outside of the air ducts yourself. When you call a professional to inspect your HVAC system, they will check for any leaks in your air ducts. Duct sealing is usually a quick process that can be completed in one day. Afterward, you should be able to use your HVAC system again within 24-48 hours. Sealing air ducts can sometimes be difficult because they are often hidden in walls, attics, basements, and other hard-to-reach places. If you're having trouble accessing your air ducts or if they are too old or damaged to repair or replace, you may need to call a professional for help. In conclusion, sealing your air ducts is an important part of maintaining an efficient HVAC system.

If you hear whistling coming from your ducts or if your energy bills suddenly increase for no reason, it's time to seal them. The interior sealing process involves spraying a specialized liquid substance throughout the interior of the air duct network and then spreading it evenly with a specialized tool. A typical home loses 20-30% of the air that passes through its duct system due to leaks, holes, and poor connections.
