One of the main problems that homeowners contend with in regards to their ductwork is the risk of air loss. In fact, 30% of an HVAC system’s air loss can come from breached air ducts. The best way to combat this and reduce costly air loss is with professional duct sealing. This may seem to you like something the average homeowner can accomplish with some simple duct tape. However, duct tape is not appropriately named and will not get the job done. Professional duct sealing involves a lot more than you may realize. We’ve summarized below.
How Do HVAC Technicians Seal Ductwork?
Clean Ducts: First off, it’s important that the exterior of your ductwork is free from dirt and debris before applying professional sealant. Our technicians will ensure that the surface is dry so that this sealant will bond to the material correctly.
Professional sealant: As mentioned above, store-bought “duct tape” is not aptly named, and as such will not get the job done. Rather, our technicians use a sticky, thick, and fibrous sealant in combo with a fiberglass or foil tape in order to successfully seal your ducts.
Even Distribution: Our technicians will use a stiff-bristled paintbrush to spread duct mastic along seams, joints, holes, and cracks of your ductwork to keep air in and to prevent leaks and other damages.
Strategic Sealing: In general, our technicians will start with the ductwork closest to your indoor unit and work their way out. This is because breaches usually tend to occur closer to the indoor unit due to the higher air pressure in this area.
To ensure you are getting the most from your duct sealing, always use a trained professional, such as the members of our staff. This way you can rely on an accurate and efficient job to keep your ductwork performing as it should for years to come.
