Do the ducts in your home need repairing?

The ducts in a home are hidden under the floors, in the walls and attic and in crawlspaces. Although they are out of sight they are certainly not out of mind, they are a critical component of a well functioning heating and air conditioning system. As the home ages there is a distinct possibility that there will be deterioration of the ducts; small holes may appear and the joints may separate, the result is poor air circulation, degraded air quality and high energy bills. There are signs that air duct repair is needed.

  • Health problems: Dirty ducts often have a negative impact on the quality of air in your home. Damaged ducts can accumulate dust and other allergens and deposit them in various rooms throughout the house. If you or a member of your family suffers from an allergy and their condition deteriorates it could be a problem associated with dirty or leaking ducts.
  • Heating and cooling: Efficient heating and cooling demands effective delivery of conditioned air. If the duct leaks the air will not be delivered to the living space, it will be delivered to the attic, crawlspace or wherever the duct is located.
  • Increase in your utility bill: When treated air is leaking into unused spaces on its way to the useable space in the house the heating and cooling system will go into overdrive. The system will be strained, it will have to work harder and longer to accomplish the task, the result is an increase in your energy bill. If this is the case in your home and there does not appear to be any other reason for an increase in your bill then you must consider that there is a leak in a duct and air duct repair should be undertaken.
  • Odd odors: If you dust the furniture in your home only to see more dust accumulate before you’re even finished it could be an air duct problem. Dust will be drawn into the duct, when the system starts up you can actually see a small puff of dust coming from the vents. The same is true with odors, your home might begin to take on a musty smell; these issues are normally associated with dirty or leaking ducts.

As much as you would hope that it never happens, air ducts do get dirty and damaged. If you are concerned about the air quality in your home and you want to drive down your energy bill then you might have to undertake air duct repair.
