Ducts and Dampers

*NOTE. Fire and smoke dampers are life safety devices, which must remain operable. All responsible staff must be familiar with their locations in the building. Check the building plans on the M or Mechanical pages to identify. A Heating, Ventilation and Air Conditioning (HVAC) contractor or local Building Inspector can provide this service. A good policy (once these dampers are located) is to clearly mark them so that future construction and service workers will not disable or block their function.

Items to include in routine maintenance are:

  • Pressure balancing.
  • Duct insulation.
  • Filter cleaning and changing.
  • Coil cleaning.
  • Valve checks for leakage and function.
  • Duct outlets operation and cleaning.
  • Fan Balance and alignment.
  • Fan bearing lubrication.
  • Fan belt tension.
  • Fan belt wear.
