Learn how sealing your home's air ducts can help improve its energy efficiency and reduce your energy bills.

Maximizing Efficiency with Air Duct Sealing

When it comes to improving the energy efficiency of your home, sealing air ducts is an essential step. There are a few different ways that contractors can seal their ducts for maximum productivity.

Duct sealant with putty

is a proven method that has been used to seal air ducts. It is a thick, pasty substance that can be applied to voids and leaks in ducts with a caulking gun and a brush.

The Aeroseal is effective because it properly seals the ducts so that outside air or dust does not enter the pipe and spread throughout the house. To get started, seal air leaks with putty or metal tape and isolate any ducts you can access (such as those in attics, tight spaces, unfinished basements, and garages). Sealing air ducts is often an afterthought in many home improvement projects, but it can have a significant impact on the efficiency of HVAC systems. Leaks in the air ducts will allow cold or warm air to escape before it reaches the desired living spaces in the house. Most homeowners don't think about sealing their home's air ducts, but the process is crucial to maintaining the home's energy efficiency.

The ducts distribute heat and air conditioning to the different rooms in the house and, often, these ducts have holes in their connections, allowing the air conditioner to escape before it reaches the intended room. In homes with forced air heating and cooling systems, ducts are used to distribute air conditioning throughout the house. A well-designed and sealed duct system can make your home more comfortable, energy efficient, and safe. However, in a typical home, about 20 to 30 percent of the air that passes through the duct system is lost due to leaks, holes, and poorly connected ducts. The air ducts work by providing convenient ways for air conditioning from the HVAC equipment to flow to the desired rooms. The self-made method of sealing air ducts saves money, but it can be quite a challenge for beginners, especially if you are trying to enter hard-to-reach areas or when there are hidden leaks behind drywall. Butyl adhesive tape and oriented polypropylene (OPP) tape are good options because they can seal duct joints surprisingly well and offer a high level of durability.

Contractors will then pressurize the duct system with a fan and use a computer to analyze the data to determine the amount of air leaving the ducts. Some people argue that the air coming out of the duct is still in the house, so energy isn't actually lost. Sealing your home's air ducts is an important step in improving its energy efficiency. It can help reduce your energy bills and make your home more comfortable. With proper sealing techniques, you can ensure that your HVAC system runs efficiently and effectively.
