1.Do you have excessively high electricity  bills in the summer or winter?

2.Does it take a long time to heat or cool a room in your home?

3.Are dust and debris being blown throughout your home?

This could be caused by holes, leaks, disconnected ducts or unbalanced air distribution. Sealing your air ducts can lead to a more comfortable, energy efficient home. According to Energy Star, about 20-30% of the air that moves through your ducts can be getting lost due to these holes or improper connections. They can cause you to be running your heating/cooling system longer and can even pull  dust and debris into your home from your attic or crawl space.
