As an HVAC expert, I have witnessed firsthand the impact that duct sealing can have on a home. It is a crucial step in ensuring that your heating and cooling system is functioning at its best, both in terms of efficiency and indoor air quality. One of the main benefits of sealing air ducts is the reduction of air leaks. In a typical home, about 20 to 30 percent of the air that passes through the duct system is lost due to leaks, holes, and poorly connected ducts.
This not only leads to higher energy bills, but it also allows for contaminants to enter the ducts and circulate throughout the house. By properly sealing and insulating ducts, you can significantly improve indoor air quality and reduce the risk of health hazards. But that's not all - sealing air ducts can also have a positive impact on your wallet. By preventing air from leaking out of the ducts before it reaches the vents, or losing/gaining heat due to lack of insulation, you can save money on your energy bills.
In fact, a well-designed and sealed duct system can even allow you to downsize to a smaller, less expensive heating and cooling system. So how do you go about sealing your air ducts? The first step is to identify any leaks or gaps in the duct system. This can be done by a professional HVAC technician or through a DIY inspection. Once identified, these leaks can be sealed with putty sealant or metal tape.
Another important step is to properly insulate any accessible ducts, such as those found in attics, mezzanines, or unfinished spaces. When it comes to choosing a company for your duct sealing project, it's important to look for those that specialize in energy-saving projects or have experience working in attics. One of the most effective solutions for duct sealing is duct putty. This sticky material does not harden, is non-toxic, and is fire-resistant, making it a safe and efficient option for sealing air ducts.
In addition to improving indoor air quality and saving money on energy bills, sealing air ducts can also solve common comfort problems in a home. By ensuring that air is properly distributed throughout the house, you can eliminate rooms that are too hot in the summer or too cold in the winter.
