The Benefits of Properly Sealing HVAC Ducts

As an expert in the HVAC industry, I have seen firsthand the impact that poorly sealed ducts can have on a building's energy efficiency and overall comfort. That's why I always stress the importance of properly sealing ducts to my clients. Not only does it save them money in the long run, but it also helps to maintain a comfortable living or working environment. Sealing ducts is necessary to prevent air leaks and ensure optimal energy efficiency. In larger commercial buildings, air leaks in the duct system can result in significant energy and monetary losses.

That's why it's crucial to hire a professional to internally seal the entire duct system. However, for homeowners who enjoy DIY projects, there is an option to seal ducts yourself using putty.

Duct putty is a proven method for sealing air ducts.

This thick, pasty substance can be applied to openings and leaks in ducts with a caulking gun and brush. If you've already made repairs but are still experiencing leaks, I recommend calling a professional like Schmidt Mechanical to help seal your ducts and keep your home comfortable all year round.

One effective method they use is Aeroseal, which properly seals the ducts to prevent outside air or dust from entering and circulating throughout the house. Aside from energy efficiency, sealing ducts also has a positive impact on the lifespan of HVAC systems. By preventing air leaks, the machine doesn't have to work as hard to maintain the desired temperature. Some may argue that since the air that filters through the ducts stays in the house, there is no real energy loss.

However, studies have shown that in a typical home, 20-30% of air passing through the duct system is lost due to leaks, holes, and poorly connected ducts.

Sealing air ducts is a crucial step in maximizing the efficiency of HVAC systems.

When it comes to sealing ducts, duct putty is widely considered the best solution by industry professionals. It's a sticky material that doesn't harden, is non-toxic, and fire-resistant. However, sealing ducts can be a challenging task as they are often hidden in walls, attics, basements, and mezzanines, making them difficult to access.

But the effort is worth it, especially for those with allergies or asthma. Sealing the duct system can help reduce symptoms and improve overall health. A well-designed and properly sealed duct system can make a home more comfortable, energy-efficient, and safe. Butyl adhesive tape and oriented polypropylene (OPP) tape are excellent options for creating a tight seal around duct joints and offering durability.

So why bother sealing ducts if it improves airflow efficiency? The answer is simple - there are numerous additional benefits to sealing air ducts. When considering a duct sealing project, it's essential to look for companies that specialize in energy-saving projects or exclusively work in attics. Once the ducts are properly sealed, you'll notice a significant improvement in utility bills, overall efficiency, and airflow. Duct sealing involves properly insulating and sealing the metal units that carry air conditioning throughout the house.
