Water-based putty duct sealant is the best choice because it cleans more easily and will hold on for a long time. When using duct sealant with putty on your own, you can apply it with a simple brush. You can also use a caulking gun to apply duct putty, although it's not necessary. In general, the best way to seal ducts is to hire a professional to do the job by internally sealing all of the duct system.
However, if your ducts are accessible and you like homeowner projects, we recommend that you buy putty, clean the outside of the air ducts, and apply putty. 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. You must use quality duct sealing compounds to properly seal the ducts. You should start with a silicone-based duct sealant that is easily applied with a putty gun.
This sealant will cover cracks and holes and keep moisture at bay. There is no filter to stop them when there are gaps in the ducts between the filter and the ventilation grilles. Therefore, hiring an expert to clean and seal the ducts could save you doctor visits and medical expenses in the future. To prevent these situations from happening, make sure the ducts are sealed, either the old-fashioned way (applying some tape, putty, and insulation) or by hiring a professional to blow liquid rubber sealant through the system. 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.
Some people argue that the air that comes out of the duct is still in their home, so energy isn't really lost. 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. This is considered internal sealing of ducts using technology and is performed by a licensed professional. Most homeowners don't think about sealing their home's air ducts, but the process is crucial to maintaining their home's energy efficiency. Meanwhile, you think your ducts are working efficiently while your energy bills are skyrocketing.
Leaks are a common problem in many homes; poorly sealed duct systems have been reported to lose about 40%. percent of heating or cooling energy. Your home's ducts carry hot or cold air from your oven's air controller to every room in your house. 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.
It is a thick, pasty substance that can be applied to voids and leaks in ducts with a caulking gun and a brush. If you clean your ducts annually, you'll notice leaks more quickly and you'll be able to fix problems before they become serious problems.
