Complete Procedure Of Air Conditioning Flex Duct
A damaged duct system significantly reduces the energy efficiency of a heating and air
conditioning system and that is where air conditioning flex duct repair becomes
necessary. Ideally, all conditioned air should be routed directly from the furnace to the
living space. In extreme cases, the energy lost due to torn or damaged ducts far outweighs
the cost of repair materials.
HVAC Duct Types
Duct systems all serve the same function. Local building codes, on the other hand,
frequently dictate the type of material used, the method of installation, and the location.
(Before we continue, remember to always wear appropriate personal protective
equipment, such as a dust mask, eye protection, and gloves.)
1. Sheet Metal Galvanized Systems:
These systems begin with a rectangular trunk line, also known as a plenum. The system
then connects the individual floor penetrations with branch lines made of either round
sheet metal or smaller rectangular ducts. S-shaped clips and cleats, also known as s-locks
and drives, hold sheet metal duct pieces together; screws hold round sheet metal ducts
together. Sheet metal duct is sealed with foil-backed duct tape or sheet metal compatible
mastic by installers. To prevent condensation while using air conditioning, some
applications, such as attics or enclosed systems, require insulation. To perform proper
cleaning of this HVAC system, immediately contact us for Air Duct Dry Fogging

2. Fiberglass Duct Board:
This type of duct is made of compressed fiberglass boards with an outer layer of foil. Each
joint is held together by foil-backed duct tape, mesh, and duct sealing compound. Rigid
fiberglass sheets are available in 1-, 1.5-, and 2-inch thicknesses from manufacturers.
3. Flexible Duct:
This simple-to-install and low-cost duct has three layers: an inner layer that holds its
shape with a spiral wire rib, a fiberg
