Poorly distributed heating and cooling throughout your home

If you notice that some rooms vary in temperature from other rooms in your house, you might need leakage. A leak of the ductwork can cause air leakages in your vents and cause your heating and air conditioning unit to fail in a room.

While dust does not always seem to cause any health problems, the dust can cause negative effects on the air quality over time and cause allergic reactions and respiratory disorders.

Utility bills are high

A major sign of duct leakage is high electricity bills. Your air ducts act as the means of transport to the conditioners. During leaks, conditioned air escapes the room before getting there to where it’s needed. In fact, your cooling unit will need a lot more work cooling your house. This extra time strain furthers the device requiring energy and therefore a higher energy bill to run.
