Do HVAC Ducts Need to be Sealed? - An Expert's Guide

To ensure optimal performance and energy efficiency, it is essential to seal the ducts along the entire length of the duct system. Air leaks in the ductwork can lead to a significant loss of energy and money, particularly in larger commercial buildings. The best way to seal ducts is to hire a professional to internally seal the entire duct system. However, if your ductwork is accessible and you are a DIY enthusiast, we recommend that you purchase putty, clean the outside of the air ducts and apply it.

Putty duct sealant is a reliable method that has been used to seal air ducts for many years. It is a thick, pasty substance that can be applied to voids and leaks in ducts with a caulking gun and a brush. Butyl adhesive tape and oriented polypropylene (OPP) tape are also good options as they can create a strong seal around duct joints and offer high durability. A well-sealed ductwork system can make your home more comfortable, energy efficient, and safer. Sealing air ducts can help reduce your home's energy consumption, making it more cost-effective in the long run. When you call Schmidt Mechanical to inspect your air conditioning system, one of the things they will inspect will be your air ducts.

Sealing ducts can sometimes be difficult because they are often hidden in walls, attics, basements and mezzanines, making them hard to access. Improved indoor air quality: Dust, dirt and musty smelling air from the attic can easily pass through small gaps and leaks in ducts and spread throughout the house once air enters. If someone in your family has allergies or asthma, sealing the duct system can help reduce their symptoms and improve their health. Your home's ducts carry hot or cold air from your oven's air controller to every room in your house. If you've done all the repairs, but the ducts are still leaking, call Schmidt Mechanical to help you seal the ducts so your home stays comfortable all year round.

Once your ducts are properly sealed, you'll get more reasonable utility bills, greater energy efficiency in your home, and better airflow and comfort. Aeroseal is an effective solution as it properly seals ducts to prevent outside air or dust from entering the pipes and spreading throughout the house. Sealing ducts helps close any of these gaps, making it nearly impossible for these air contaminants to enter. Increased longevity of air conditioning systems: Sealing ducts helps heating and cooling systems, allowing the machine to work less to maintain air temperature. In summary, sealing HVAC ducts is essential for optimal performance and energy efficiency. It helps reduce energy consumption, improve indoor air quality, and increase the longevity of air conditioning systems.

If you're looking for an effective way to seal your HVAC ducts, we recommend hiring a professional or using putty or adhesive tape.
