Start by sealing air leaks with putty sealant or metallic tape and isolate any ducts you can access (such as those in attics, mezzanines, unfinished basements, and garages). Never use adhesive tape, as it doesn't last long. Apply a layer of silicone putty along both edges of the duct joint. Seal round ducts with aluminum foil tape, not duct tape.
Despite its name, it's not approved for sealing ducts 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 injected spray sealant system, follow the instructions described below. Using the fan, they will spray the inside of the duct system with a liquid rubber sealant, which will cover all holes, cracks, and joints that leak air. All joints and joints in air ducts, air treatment systems, and filter boxes are practically hermetic using tapes, putties, liquid sealants, gaskets, or other approved sealing systems.
In those cases, the evaluator will visually verify that all joints and connections are sealed with putty or metal tape and that all duct covers are sealed to the floor, wall, or ceiling with putty, foam, or adhesive tape. It is a thick, pasty substance that can be applied to voids and leaks in ducts with a caulking gun and a brush. Experts believe that 20 to 30 percent of the costs of heating, ventilation and air conditioning services are due to leaks in the ducts, money that translates into a lot of changes over several months. Sealing ducts from the inside out is a much more complicated process and will probably require hiring a professional.
Duct leaks allow contaminated air to enter the system, increasing pollutants inside the house, including dust, dirt, and other particles that decrease air quality. A convenient option is to take a gallon bucket full of duct sealant and apply it directly with the help of a brush. If someone in your family has allergies or asthma, sealing the duct system can help reduce their symptoms and improve their health. Leaks are a common problem in many homes; poorly sealed duct systems are reported to lose around 40 percent of heating or cooling energy.
In those cases, the evaluator will visually verify that the trunk is durably sealed to the subfloor (for example, having properly sealed ducts will help balance the air temperature in the house and improve air quality). You can apply high-quality adhesive tape (the old-fashioned way), putty, or Aeroseal sealant for better results. Professionally sealed Comfort supply systems are significantly airtight at all seams and connections. If you're looking for an effective way to seal leaks in your home's ductwork system then you've come to the right place.
Sealing your ducts is essential for maintaining good indoor air quality as well as reducing energy costs. The most common methods for sealing leaks include using putty sealant or metallic tape for air leaks; aluminum foil tape for round ducts; silicone putty for joints; foam or adhesive tape for covers; liquid rubber sealant for holes; and high-quality adhesive tape or Aeroseal sealant for better results. Using a caulking gun and brush is one of the most effective ways to apply thick pasty substances like putty or sealant directly onto voids and leaks in your ductwork. This method is also recommended if someone in your family suffers from allergies or asthma as sealing your ducts can help reduce their symptoms.
Finally, it's important to note that having properly sealed ducts can help balance the air temperature in your home as well as improve air quality. So if you're looking for an effective way to save money on energy costs while improving indoor air quality then sealing your home's ductwork is definitely worth considering.
