Ductwork is often the most neglected part of an HVAC system because it is hidden from everyday view. Your ducts run through wall, crawl, attic, and basement spaces carrying conditioned air to your home’s living spaces. Aging ductwork can begin to have issues that compromise the efficacy of the airflow, as well as overall energy efficiency.
Depending on the age and condition of your ducts, repairs or replacement may be needed to get your system working efficiently again. The following are indicators that aging ductwork is negatively impacting your Gary area home.
They are 15-years old or more. If your home was built in the 1990s or prior, the ducts were probably designed according to cost efficiency, rather than energy efficiency. Now, HVAC contractors use Manual D to adequately size and design ductwork for the most efficient layout and air delivery. Have your ducts inspected to see if a redesign is in order.
Ducts are corroded or leaky. Over time, duct materials, mastic tape and caulk can corrode and will cause the joints and seams to split or disconnect completely. If you are able to peek into your crawl spaces or up over the attic hatch, take a look at the exposed ductwork and see if you notice any gaps, peeling tape, or signs of rust. Dust streaks running away from the seams are another sign of leakage. Leaks are a common airflow obstruction and are a major source of energy waste.
Inconsistent airflow. Walk room to room while your HVAC system is working. If some areas have weaker airflow than others, it is a sign that ducts have large leaks, disconnections, or collapsed segments.
Use a duct blower test. Schedule a duct blower test with your HVAC contractor. This test takes a measurement of the airflow through the ducts, and can provide an exact ratio of air leakage to airflow.
Your HVAC contractor will be able to advise you on whether your ducts can be repaired, or if a full redesign would be more cost effective in the long run.
