Whether you are trying to heat or cool your home you will need air ducts that are in good condition; the ducts within your home can become damaged or worn-out overtime and develop gaps allowing air to escape while letting dust and other particles in. Some reasons for needing duct repair or replacement include but are not limited to water or fire damage, rodent or insect infestation, collapsing flexible or fiber ducts, multiple replacement systems over the years, and a lack of insulation.
