Reattaching and Securing Loose Ducts

Leaky or disconnected ductwork often accounts for 10 to 30 percent of total heating and cooling costs. For an average home, leaky ducts can waste hundreds of dollars each year. While the increase in energy cost is significant, protecting health and safety is the most important reason to seal ducts.
Ducts are usually located in the attic, crawl space or basement. If the return ducts leak, they draw air from these areas directly into the home. This air can be contaminated with dust, mold, mildew, excess humidity, and potential toxins such as pesticides for termite treatment, combustion gases, and radon. When supply ducts leak, they can create a lower pressure inside the house which draws in contaminates, too. Holes in the return ducts are not the only source of wasted energy from leaky ducts. If you have holes or gaps in your supply ducts, some of that nice warm or cool air is being blown out into the attic space or crawl space and other places you don't want it to go. That means less air is being pushed into the living space than is being pulled out of the living space through the return ducts. Since Nature abhors a vacuum, air from outside the house is pulled through cracks and other openings in the house's walls. In other words, you will be creating a pressure imbalance in your living space that sucks in cold or hot air from outside your house. That outside air will be cold in the winter and hot in the summer - reducing your comfort and making your heating or cooling equipment work harder than necessary.
We can detect duct system leaks, cuts, and disconnections by measuring negative air pressure inside the duct system and using a video camera. After we find the exact location of leakage, the damaged duct will be replaced or repaired.
