Furnace-to-Heat-Pump Conversion in Fredericton
A furnace-to-heat-pump conversion can range from adding a heat pump to an existing furnace to replacing the furnace with an electric air handler. Existing ducts and backup-heat strategy determine much of the project.
Homes with usable forced-air ducts already have the distribution system a central heat pump needs. The main question is whether the existing furnace remains as backup or is replaced by an air handler with electric auxiliary heat.
Furnace add-on option
A heat pump can sometimes be integrated with an existing furnace so the heat pump handles much of the season and the furnace assists under selected conditions. Equipment compatibility, controls and duct airflow need to be checked.
Full furnace replacement
If the furnace is near end of life or electrification is the goal, a heat-pump air handler may replace it. This can change electrical requirements and backup-heat planning.
Do not ignore the ducts
Returns, filter size, static pressure and supply balance affect comfort after the conversion. A new outdoor unit cannot correct undersized or poorly distributed ductwork by itself.
