As an expert in the field of heating, ventilation, and air conditioning (HVAC), I have seen firsthand the impact that leaking ducts can have on a home's energy efficiency and air quality. That's why it's crucial to properly seal air ducts with the right materials.
One of the most effective ways to seal leaking ducts is with high-quality air conditioning duct sealing tape.
While duct tape may seem like a quick and easy fix, it is not a long-term solution and can end up costing you more in the long run. In fact, experts estimate that 20 to 30 percent of HVAC costs are due to duct leaks, which can add up to a significant amount over time.To properly seal round ducts, I recommend using high temperature UL181 aluminum tape, which can be found in the duct section of most home improvement stores. This type of tape is specifically designed for use in HVAC systems and is durable enough to withstand high temperatures. But before you start sealing your ducts, it's important to first identify any air leaks and address them. This can be done by using putty sealant or metal tape to seal any gaps or holes in the ducts.
Additionally, it's important to insulate any accessible ducts, such as those in attics, mezzanines, unfinished basements, and garages. This will prevent hot or cold air from escaping and causing your HVAC system to work harder than necessary. So why is it so important to seal air ducts? Well, when air leaks out of the ducts, it not only affects the efficiency of your HVAC system but also impacts the air quality in your home. Leaks allow contaminated air to enter the system, bringing in dust, dirt, and other particles that can reduce the overall air quality in your home.
That's where computer technology comes in. By using precise measurements and applying the right amount of sealant, we can ensure that your ducts are properly sealed without any mess or guesswork. This not only improves the effectiveness of the sealant but also ensures that it doesn't get dirty during the sealing process. When it comes to choosing a sealant, there are a few options available.
High-quality adhesive tape, putty, and Aeroseal sealant are all effective choices. However, it's important to note that in a typical home, 20 to 30 percent of air passing through the duct system is lost due to leaks and poorly connected ducts. That's why it's crucial to choose a sealant that will provide long-lasting results. Butyl adhesive tape and oriented polypropylene (OPP) tape are both great options for sealing duct joints.
They create a strong seal and offer high durability, ensuring that your ducts stay properly sealed for years to come. One popular option for sealing air ducts is Aeroseal. While its name may suggest that it's specifically designed for duct sealing, it is not approved for this purpose and does not hold up well in the long term. It's important to choose a sealant that is specifically designed for use in HVAC systems to ensure the best results.
Air duct leaks can have a significant impact on your home's energy efficiency and air quality. When warm or cool air escapes before reaching the desired living spaces, your HVAC system has to work harder to maintain the desired temperature. This not only leads to higher energy bills but also puts unnecessary strain on your system. But the benefits of properly sealing air ducts go beyond just improving airflow efficiency.
It can also have a positive impact on your health. If anyone in your household suffers from allergies or asthma, sealing the duct system can help reduce their symptoms by preventing outside air and pollutants from entering the home.
