Retrofit Systems
When converting from forced-air systems (electric,
gas, or oil) to a heat pump, proper design is still important. The existing
ductwork is probably adequate for the existing system, but may be undersized
for a heat pump. In some situations it's best to remove the old system,
including ductwork. Then a properly designed heat pump, including ductwork, can
be installed.
If the existing ductwork is adequate for airflow
with the properly-sized heat pump, then duct sealing using a blower door
pressure test and mastic sealant for the leaky spots is recommended.
To allow your heat pump to operate at its maximum
efficiency, your home should be adequately weatherized prior to the design of
the heat pump system. Contact your electric utility for information on home
weatherization including:
