What should be used to seal leaks in ductwork?

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. 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. To manually seal parts of the duct system that have not been treated with the spray-injected sealing system, follow the steps described below. Ideally, all air flowing through the air treatment device reaches the ends of the supply grid without air leaks, and that all air entering through the return duct grilles returns to the air handler without leaking. It is recommended to seal them manually with fiberglass mesh tape and putty, and the duct material should have an interior air barrier.

It's fascinating to explain how sealing air ducts can help reduce your home's energy consumption. Professionally sealed comfort delivery systems are considerably airtight in all seams and connections. Some people argue that the air that comes out of the duct is still in their home, so energy isn't really lost. For aerosol sealant applications, follow the system vendor's instructions; normally, this work will be performed by a factory-authorized technician.

Either way, having properly sealed ducts will help you balance the air temperature in your home and improve air quality.

Experts believe that 20 to 30 percent of public heating, ventilation and air conditioning costs are due to leaks in pipelines, representing a significant part of the changes over several months. In addition, if leaking ducts are in spaces where there is dust or dirt, those contaminants can be absorbed by the system and distributed throughout the house. They will then pressurize the duct system with a fan and use a computer to analyze the data and determine how much air escapes through the ducts.

Most homeowners don't think about sealing their home's air ducts, but the process is crucial to maintaining their home's energy efficiency. Sealing ducts generally reduces the risk of combustion safety problems, such as air build-up. However, it is necessary to check the effects of duct sealing on combustion appliances and ventilation grilles to confirm that narrower ducts do not adversely alter the pressure dynamics of the house and cause problems of this type. Duct leaks allow contaminated air to enter the system, increasing the amount of contaminants inside the house, such as dust, dirt and other particles that decrease quality of the air.
