Repair Duct system
Repair
Duct system repair involves reconnecting
parts that have become separated, and
replacing or repairing any damaged or
missing component parts, which could
include flexible metallic and non-metallic
“plastic flex” ducts, rigid metal ducts, sheet
metal duct components, duct supports,
register boots, and registers.
Renovation
Duct renovation should be performed if the
duct system is in poor condition or improperly
sized. Renovation involves replacing a
significant portion of the ductwork, either to
restore it to proper operation or to increase
the capacity of the return air ducting. Some
systems have return ducts that are too small,
causing whistling filters, noisy ducts, and
reduced energy efficiency. If size is not the
problem, often only a portion of the ductwork
needs replacement. But if the entire duct
system needs to be replaced, your contractor
must correctly size the ducts and registers to
ensure that the new ductwork will provide the
most comfort and greatest energy efficiency
