Quick answer
Have a qualified contractor size, install and maintain it. Heat pumps usually move more air than furnaces, so some homes need ductwork changes, and some need electrical service upgrades. Cost depends on the type of system, your goals and the heating equipment and ducts you already have.1
Hire a qualified contractor
Natural Resources Canada recommends having an air-source heat pump installed by a qualified contractor, and consulting a local heating and cooling professional to size, install and maintain the equipment so it runs efficiently and reliably.1
Your ductwork may need changes
If a heat pump will replace or work alongside a central furnace, keep in mind that heat pumps generally run at higher airflows than furnaces. Depending on the heat pump's size, the ductwork may need modifications to avoid extra noise and fan energy use. Your contractor can tell you what applies to your home.1
Check your electrical service
Some installations need changes to the home's electrical service to support the new heat pump.1 Reducing heat loss first can help keep the system, and its supplementary heat, smaller, which is one way Natural Resources Canada's best practices videos show homeowners avoiding costly panel upgrades.2
What affects the cost
- The type of heat pump system.1
- Your design goals, such as whether it replaces or supplements existing heating.1
- The heating equipment and ductwork already in your home.1
- Any electrical service changes needed.1
A simple checklist
- Seal air leaks and add insulation where it's thin.
- Get a heat-loss calculation and a properly sized system.
- Ask whether your ducts can carry the airflow.
- Confirm your electrical panel's capacity.
- For Ontario's rebate, get pre-approval before installation.3

Common follow-up questions
Will a heat pump be louder than my furnace?
It shouldn't be if the system is sized correctly and the ductwork can handle the higher airflow. Your contractor should check the ducts before installation.
Do all homes need an electrical upgrade for a heat pump?
No. Some do, depending on the system and the home's existing electrical service.
