Ducted & Central Heat Pump Installation in Duncan
Whole-home ducted and central systems for houses with existing ductwork, sized for Duncan's -6°C winter design temperature.
Duncan Heat Pumps installs ducted and central heat pump systems across Duncan and North Cowichan for homes with existing forced-air ductwork, sized to the region's -6°C winter design temperature. A central ducted system typically runs $8,000 to $18,000 before rebates, and CleanBC's Energy Savings Program can offset up to $13,000 of an eligible fossil-fuel conversion.
A ducted or central heat pump connects to your home's existing forced-air ductwork and heats and cools the whole house from one outdoor unit, in place of or alongside a furnace. It suits homes that already have ductwork from a previous furnace or central air system. Your system is sized to a heat-loss calculation against Duncan's -6°C winter design temperature, and installation is carried out by a CleanBC program-registered contractor.
A central ducted heat pump installation in Duncan typically runs $8,000 to $18,000 before rebates, depending on system size and whether your electrical panel needs upgrading.
What's included in your ducted installation?
A complete installation covers system sizing, supply and installation of the outdoor condenser and the indoor air handler, connecting to your home's existing ductwork, the electrical connection, and start-up testing. We pull the Technical Safety BC electrical permit and remove the old equipment on completion.
How do we size a system for your house?
The BC Building Code lists Duncan's winter design temperature at -6°C, with 2,980 heating degree-days below 18°C — a colder profile than much of the south Island. A heat-loss calculation sets your system's size against that design temperature and your home's insulation and window area, so your system holds its output on the coldest days rather than only in mild weather.
What rebates apply, and why does a registered contractor matter?
CleanBC's Energy Savings Program is income-tested and pays up to $13,000 toward an eligible fossil-fuel-to-heat-pump conversion, and Duncan and North Cowichan both add a $350 municipal top-up on qualifying electric heat pump installations. Only work completed by a CleanBC-registered contractor qualifies for the program.

Local conditions
The BC Building Code lists Duncan's winter design temperature at -6°C with 2,980 heating degree-days below 18°C, a colder profile than much of the south Island. A ducted system is sized against that design temperature rather than a moderate fall or spring day, so it holds its rated output through the coldest part of the winter.
In practice
- Situation
- A North Cowichan home with an ageing oil furnace and existing ductwork needed a full heating replacement before winter.
- Complication
- The existing ductwork was original to the house, and a straight swap for the same furnace output would have left the system undersized against the region's actual design temperature.
- Resolution
- A central ducted heat pump was sized to a heat-loss calculation and connected to the existing ductwork, with CleanBC's fossil-fuel conversion tier applied to the oil furnace replacement.
People also ask
Can a ducted heat pump use my home's existing ductwork?
Yes, when your ductwork is in good condition. Your system is sized to your home's heat-loss calculation before it's connected.
Will a ducted heat pump keep up at -6°C?
A cold-climate-rated ducted system is sized against Duncan's -6°C winter design temperature as part of the heat-loss calculation.
Is an electrical permit required for a ducted installation?
Yes. Technical Safety BC requires an electrical permit for most heat pump installations, arranged as part of the job.
How much can CleanBC's rebate offset a ducted installation?
CleanBC's Energy Savings Program is income-tested and pays up to $13,000 toward an eligible fossil-fuel conversion, plus a $350 municipal top-up from Duncan or North Cowichan.
