Ducts are pivotal in transferring heat from the source to your entire home. All furnaces have an extensive network of ducts, which is impossible to maintain all the time; therefore, routine annual maintenance services are recommended. However, if your furnace has been lacking maintenance for a long time, there is a high chance that your ductwork has developed leaks and the heat is wasted.
According to the US Department of Energy, leaking ductwork can waste almost one-third of your furnace’s total heat yield, which is a massive amount. These leaks are tiny cracks, holes, and air gaps in the ductwork with big impacts on heat wastage. Thus, you might not see the leaks, but a skilled technician will immediately notice them.
