Flexible ducts might be less expensive to have installed, but they will cost you more in the long run. They are made with a less than durable material to make it easier to bend them and maneuver them around obstacles. This means they breakdown at a more rapid rate than the sturdy sheet metal ducts. Breakdowns in your flexible ducts means air that you pay to heat and cool your home is leaking inside the walls - never getting to your living space. We don't want your ducts to resemble these found in a Wilmington, DE home. So contact Dr. Energy Saver today for your free duct inspection!
