How to Determine if Ducts Need Repairs

Duct repair in Eugene and Springfield, Oregon The most reliable and cost-effective way to find out if your system needs repairs is to have a duct test performed by a qualified Marshall's technician, using the proper test equipment. Duct testing is the process of using calibrated mechanical equipment to measure the amount of airflow that is lost through the duct system when it is at normal operating pressure.

While some joints or seams may have only small leaks, other sections may be completely disconnected. Duct testing can indicate the relative leakiness of the ducts and help determine whether the duct system should be sealed, repaired, or renovated.

Duct Sealing

Duct sealing involves following established procedures and applying approved materials to seal air leaks. Locations where sealing is typically performed include the supply and return plenums (which are connected to the furnace cabinet), starting collars (where ducts are connected to the plenums), fittings in the duct runs (Ys, where ducts branch off, and elbows), splices within the duct run, and terminations where the ducts connect to the supply registers.

The most important leakage areas are in the supply and return plenums, because these areas are closest to the air handler and under the highest pressures when the system is operating. All sealing must be performed according to specific building codes and any related energy efficiency program standards. Marshall's technicians are familiar with, and follow the standards and codes for duct sealing.
