Ducts carry cooled or heated air through a home's HVAC system and remove stale air. There are several types of ducts including sheet metal, fiberglass lined, fiberboard, and flex ducts. Sheet metal ducts are the most durable but fiberglass lined and fiberboard ducts provide insulation and sound dampening. Flex ducts are best for tight spaces but can kink. Getting your ducts assessed can help determine if an upgrade is needed.
2. What are ducts
and why are they
important? Simply put, a duct is
the channel that
carries cooled air from
the air conditioning
unit through your
home, and also
removes warm or stale
air. Ducts are also used
for heating and
filtering systems.
