The Benefits of Sealing Air Ducts: An Expert's Guide

When it comes to improving the efficiency of your HVAC system, sealing air ducts is often an overlooked step. However, sealing air ducts offers a multitude of advantages, from reducing energy consumption to improving the health of those with allergies or asthma. But how do you go about sealing air ducts?The most common method is to use an air duct sealant with putty. Putty is a sticky substance that hardens after being applied to ducts.

You can also use high-quality adhesive tape, putty, or Aeroseal sealant for better results. Each method has its own benefits and drawbacks, so let's take an in-depth look at what technique you can use and why. Adhesive tape is a good option for temporary solutions, but it can reduce the lifespan of your HVAC system if applied incorrectly. Butyl adhesive tape and oriented polypropylene (OPP) tape are good options because they can seal duct joints effectively and offer a high level of durability. Due to the lack of airtightness at the lower limit of the duct system, it is recommended to start the sealing process from where the air pressure is highest. Sealing air ducts can help reduce your home's energy consumption and improve the health of those with allergies or asthma. Sealing air ducts by yourself saves you money, but it can be a challenge for beginners, especially if you're trying to get into hard-to-reach areas or when there are leaks hidden behind drywall.

It's important to understand the different methods available and choose the one that best suits your needs. If you're looking for a more permanent solution, then Aeroseal sealant is your best bet. This sealant is injected into the ductwork and expands to fill any gaps or cracks in the system. It's also non-toxic and safe for use in homes with children or pets. No matter which method you choose, it's important to make sure that all joints are properly sealed. This will ensure that your HVAC system runs efficiently and that your home remains comfortable all year round.

Sealing air ducts is an easy way to save money on energy bills and improve indoor air quality.
