Flexible Duct Vs Metal Duct

This is because they re more versatile and flexible.

Flexible duct vs metal duct.

Flex ducts are better for existing trunk and branch heating and cooling systems. Continue reading below our video of the day. Flex must be oversized at least one duct size. Even when doing this the flex duct creates much more resistance.

Flexible ducts are fairly easy to install and will often cost less than the rigid ductwork. Having seen the results from a duct blaster on many different configurations of residential duct work i would recommend keeping the metal duct work and cleaning it. Installation of rigid metal ducting must be completed by an experienced skilled professional and is often more complicated to be installed than flexible ducting. This is due to the heavy planning it requires and if something is not well thought through it is normal for the technicians to come into a bit of a situation.

Flex duct has an inherent flaw based on the very attributes that make it flexible. While sheet metal ductwork tends to be a better long term choice flexible ductwork has the advantage of relatively low upfront cost and versatility. Air flow in a flex duct tends to tumble probably because of the rib like intrusion every inch or so. Flexible ductwork is going to be cheaper than metal ducts in nearly every case.

What s the best choice for you. When you are trying to stick to a budget on the project this savings can help you do so. Flexible ducts are good for air quality because you are not breathing in fiberglass insulation lined ductwork like the fiber air ducts and they are mold and rust resistant unlike galvanized sheet metal ductwork. Rigid ductwork sheet metal ducts are less likely to incur dangerous mold and growths because their surfaces are non porous and smooth.

Air flow in a steel duct tends to travel smoothly in a coil like motion. It all depends on the unique needs of your home and your budget. In comparison to metal duct flex duct is easier and faster to install.
