Duct Sealing is the sealing of leaks in air ducts in order to reduce air leakage, optimize efficiency, and control entry of pollutants into the home or building. Air pressure combined with air duct leakage can lead to a loss of energy in a HVAC system and duct sealing solves issues of energy loss in the system.
Before sealing duct work it is imperative to ensure the total external static pressure of your duct work and equipment will fall within your equipment manufacturer's specifications. If not, higher energy usage and reduced equipment performance may be expected.
Duct tape is not used for sealing ducts. Building codes call for special fire-resistant tapes, often with foil backings and long lasting adhesives.
Signs of leaky or poorly performing air ducts include:
- Utility bills in winter and summer months above average relative to rate fluctuation
- Spaces or rooms that are difficult to heat or cool
- Duct location in an attic, attached garage, leaky floor cavity, crawl space or unheated basement.

Famous quotes containing the word sealing:
“Woe to that nation whose literature is cut short by the intrusion of force. This is not merely interference with freedom of the press but the sealing up of a nations heart, the excision of its memory.”
—Alexander Solzhenitsyn (b. 1918)
