Flexible Duct Vs Metal Duct

Flexible ducts are fairly easy to install and will often cost less than the rigid ductwork.

Flexible duct vs metal duct.

Metal ducts are more rigid due to the nature of steel making them ideal to build an entire hvac system. 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. The inner liner ribs restrict airflow more than sheet metal ductwork but not significantly. Installation of rigid metal ducting must be completed by an experienced skilled professional and is often more complicated to be installed than flexible ducting.

Flex ducts are better for existing trunk and branch heating and cooling systems. While sheet metal ductwork tends to be a better long term choice flexible ductwork has the advantage of relatively low upfront cost and versatility. 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. When you use flexible ductwork instead of metal ducts you will save some substantial money.

This is because they re more versatile and flexible. Air flow in a steel duct tends to travel smoothly in a coil like motion. Flexible ductwork is going to be cheaper than metal ducts in nearly every case. Even when doing this the flex duct creates much more resistance.

What s the best choice for you. Air flow in a flex duct tends to tumble probably because of the rib like intrusion every inch or so. It all depends on the unique needs of your home and your budget.
