How should ductwork be sealed against air leaks?

Start by sealing air leaks with putty or metal tape and insulate any ducts you can access (such as those in attics, mezzanines, unfinished basements, and garages). Never use adhesive tape, as it is not durable. You can apply high-quality adhesive tape (the old fashioned way), putty or Aeroseal sealant for best results. Each method has its advantages and disadvantages, so let's take an in-depth look at what technique you could use and why.

Apply a layer of silicone caulk along both edges of the duct joint. Seal round ducts with aluminum foil tape, not adhesive tape. Despite its name, it's not approved for duct sealing and doesn't hold up well in the long term. Duct leaks allow contaminated air to enter the system, increasing contaminants inside the house, such as dust, dirt and other particles that decrease air quality.

As you know, your air conditioner does more to control the temperature of a room than simply produce cool air. Leaks in the air duct will allow cold or warm air to escape before it reaches the desired living spaces in the house. Buy UL181 high-temperature aluminum tape in the duct section of a residential center and use it to seal the joints of round ducts. Then, they will pressurize the duct system with a fan and use a computer to analyze the data and determine the amount of air that escapes through the ducts.

Most homeowners don't think about sealing their home's air ducts, but the process is crucial to maintaining the energy efficiency of their home. Either way, having your ducts properly sealed will help you balance the air temperature in your home and improve air quality. Butyl adhesive tape and oriented polypropylene (OPP) tape are good options because they can create a surprisingly good seal around duct joints and offer a high level of durability.

Sealing air ducts

is often an afterthought in many home improvement projects, but it can improve or decrease the efficiency of HVAC systems.

If someone in your family has allergies or asthma, sealing the duct system can help reduce their symptoms and improve their health. So, in addition to improving airflow efficiency, why worry about sealing ducts in the first place? Sealing air ducts offers a multitude of additional advantages. Some people argue that the air that comes out of the duct is still in their home, so energy isn't really lost. It's fascinating that you explain how sealing air ducts can help reduce energy consumption in your home.

You can further improve indoor air quality with an air filter, which you won't have to change very often because there won't be as much dust or dirt to clean.
