Project Description


1. Residential Duct Work
Duct work is simply an air delivery system. A delivery system for all forced air systems, furnace or air handler, heating or air conditioning, or both.

Duct delivers fresh air and humidification into your home. Duct work is the channel through which the air in your home is filtered and purified, or expelled to the outdoors and replaced with fresh new air.

Each component of the duct air delivery system, from the air handler to the registers, adds a certain amount of resistance to the airflow. This resistance is friction loss.
