How Much Energy is Lost Through Ductwork? A Comprehensive Guide

The average air duct system can be responsible for a significant amount of energy loss, with estimates ranging from 25 to 40 percent. According to Energy Star, up to 30 percent of the air that passes through a duct system is lost due to leaks, holes, and poorly connected ducts. This means that a fifth of the air circulating through your home is not providing the necessary heating or cooling. If the system has significant leaks, you may lose more than the normal percentage.

Not only does this result in energy loss, but it can also pose serious health risks. Poorly sealed ducts can allow dust, pollen, and other allergens to enter your home, leading to respiratory issues and other health problems. Fortunately, there are ways to reduce the amount of energy lost through ductwork and improve the overall health of your home. Sealing and insulating ducts can help save energy, improve indoor air quality, and increase safety.

Sealing ducts is a relatively simple process that involves using mastic sealant or metal-backed tape to close any gaps or holes in the ductwork. This will help reduce air leakage and improve the efficiency of your heating and cooling system. Insulating ducts is also important for reducing energy loss. Insulation helps keep the air inside the ducts at a consistent temperature, which reduces the amount of energy needed to heat or cool it.

It also helps reduce noise from the system and prevents condensation from forming on the outside of the ducts. By sealing and insulating your ducts, you can reduce energy loss and improve the overall health of your home. This will help you save money on your energy bills and ensure that your home is comfortable all year round.
