Sealing your air ducts is a great way to keep your home energy efficient, save money, and improve the air quality. But how much does it cost? The cost of sealing your air ducts will depend on the type of insulation you choose, the thickness of the insulation, and the complexity of the duct system. The most common insulating materials used for air ducts are fiberglass, cellulose, and foam. The cost of installation per square foot is usually around 3 inches of material.
It is important to note that if the ducts are not already sealed or insulated, the project cost will be higher than if they were already sealed. You may want to consider consulting a professional insulation contractor in your area for a project quote. They can use water-based aerosol sealants to seal the ducts internally and ensure that all leaks are properly sealed. Additionally, they can check for any rodents in the ducts that may be introducing bacteria and diseases into your home.
As a general rule, plan to install at least 3 inches of insulation in all of your home's HVAC ducts. However, if the ducts are rusted or corroded, they may need to be replaced, which will increase costs as it may include new parts of duct material and sealants. Duct sealing is part art and part science, and results in a system of well-insulated and sealed ducts that efficiently supply air to all parts of the house. The disadvantage of air-sealing your own ducts is that there may be places that are nearly impossible to reach within the air duct system. In conclusion, sealing your air ducts can be a great way to save money in the long run. The cost will depend on the type of insulation you choose, the thickness of the insulation, and the complexity of the duct system.
