Why is air duct sealing important?
It’s been estimated that twenty to thirty percent of air moved through ductwork is lost through holes, leaks, or poorly connected air ducts. Air duct sealing can lower energy bills, improve your HVAC system’s ability to keep your home a comfortable temperature, and even improve your home air quality. By sealing your air ducts you can keep dander, dirt, dust, mold, spores, and other pollutants out of your air supply – lowering the chances of experiencing respiratory issues and generally improving indoor air.
What methods are used to seal air ducts?
- Tape Air Duct Sealing- This is the least long-lasting method of ductwork sealing. It’s best performed on only a small single leak, as over time tape adhesive wears off, causing the tape to fall off. ONLY use butyl or foil tape, and NEVER use duct tape.
- Mastic Air Duct Sealing– This sticky substance can be used to seal ductwork by applying it to holes or leaks with a caulking gun or a paintbrush. It is longer-lasting than tape, but can be messy. Mastic should not be used on holes or cracks that are larger than a quarter of an inch.
- Aeroseal Air Duct Sealing– THis highly effective method of air duct sealing is applied by a professional technician. All vents and registers will be blocked with foam plugs, and then flexible tubing will be attached to your duct system through a temporary access hole. The entire air duct system will be filled with air pressure to check for leaks anywhere before the sealant is released. Aeroseal is applied with immense precision, with just the right amount of sealant being applied to seal cracks or holes in ductwork.
Duct Armor Air Duct Sealing– This water-based latex sealant lining is professionally installed on ductwork through application to duct interiors. Once Duct Armor dries, it creates a perfect barrier between air ducts and the outside air. It is ideal for preventing contaminants from entering your home, while also improving how fast your HVAC system can cool or heat your home – potentially lowering your energy bills and improving your HVAC system lifespan by reducing strain.
