 Air Condition and Ventilation Ducting
what is a duct?
a duct is the channel that carries cooled air from the air conditioning unit through your home, and can also remove warm or stale air. Ducts for central air conditioning can also be used for heating and filtering systems.
Flexible ducts are typically tube-shaped, made of a wire coil covered with a bendable, durable plastic, and surrounded by insulation. This kind of ducting is best in tricky spaces where rigid ducts are just not possible to install, or used to attach non-flexible duct work to an air supply outlet. Like most central air conditioning parts, flexible ducts have specific installation requirements. For example, flexible duct work needs to be secured and supported properly, ensuring little sagging or snaking. Kinks, bends, and turns also need to be minimized – these reduce air flow and could hamper the efficiency and effectiveness of the air conditioner. The advantages of flexible ducts are that they are fairly quick and easy to install, and often cost less than rigid duct work.
