Ducts are an
integral part of
a forced-air
heating or
cooling system
and their
purpose is to
circulate air to
evenly heat and
cool your home.
Unfortunately,
ducts are often
leaky – wasting
7-12% of heating
and cooling
energy used by
your home. How
do I know if my
ducts need
repairs?
The following
can be signs
that your ducts
need repair and
sealing:
- Rooms
are too warm
or too cold
- High
summer and
winter
utility
bills
- Little
or no air
flow from
registers in
some rooms
- Air
filter gets
dirty
quickly –
needs to be
changed more
than once a
month –
indicating
leaks in
return
ducts.
- Streaks
of dust at
registers or
duct
connections
- No
insulation
on visible
ducts (those
in an attic
or crawl
space)
- Flexible
ducts are
tangled or
kinked
Who
can fix my
ducts?
There are some
repairs you may
be able to do
yourself or you
can hire a
heating and
cooling
contractor that
specializes in
duct repair.
These
contractors use
special
diagnostic
equipment to
check duct
pressures, air
flow and leakage
to assess the
efficiency of
your duct system
and prescribe
improvements.
